|
||||
|
||||
The easiest way to install tippecanoe on OSX is with [Homebrew](http://brew.sh/):
|
||||
|
||||
```sh
|
||||
```js
|
||||
$ brew install tippecanoe
|
||||
```
|
||||
|
||||
On Ubuntu it will usually be easiest to build from the source repository:
|
||||
|
||||
```sh
|
||||
$ git clone https://github.com/mapbox/tippecanoe.git
|
||||
$ cd tippecanoe
|
||||
$ make -j
|
||||
$ make install
|
||||
```
|
||||
|
||||
See [Development](#development) below for how to upgrade your
|
||||
C++ compiler or install prerequisite packages if you get
|
||||
compiler errors.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
```sh
|
||||
$ tippecanoe -o file.mbtiles [options] [file.json file.json.gz file.geobuf ...]
|
||||
$ tippecanoe -o file.mbtiles [file.json ...]

If no files are specified, it reads GeoJSON from the standard input.

@ -67,204 +52,6 @@ You can concatenate multiple GeoJSON features or files together,
|
||||
and it will parse out the features and ignore whatever other objects
|
||||
it encounters.
|
||||
|
||||
Try this first
|
||||
--------------
|
||||
|
||||
If you aren't sure what options to use, try this:
|
||||
|
||||
```sh
|
||||
$ tippecanoe -zg -o out.mbtiles --drop-densest-as-needed in.geojson
|
||||
```
|
||||
|
||||
The `-zg` option will make Tippecanoe choose a maximum zoom level that should be
|
||||
high enough to reflect the precision of the original data. (If it turns out still
|
||||
not to be as detailed as you want, use `-z` manually with a higher number.)
|
||||
|
||||
If the tiles come out too big, the `--drop-densest-as-needed` option will make
|
||||
Tippecanoe try dropping what should be the least visible features at each zoom level.
|
||||
(If it drops too many features, use `-x` to leave out some feature attributes that
|
||||
you didn't really need.)
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
Create a tileset of TIGER roads for Alameda County, to zoom level 13, with a custom layer name and description:
|
||||
|
||||
```sh
|
||||
$ tippecanoe -o alameda.mbtiles -l alameda -n "Alameda County from TIGER" -z13 tl_2014_06001_roads.json
|
||||
```
|
||||
|
||||
Create a tileset of all TIGER roads, at only zoom level 12, but with higher detail than normal,
|
||||
with a custom layer name and description, and leaving out the `LINEARID` and `RTTYP` attributes:
|
||||
|
||||
```
|
||||
$ cat tiger/tl_2014_*_roads.json | tippecanoe -o tiger.mbtiles -l roads -n "All TIGER roads, one zoom" -z12 -Z12 -d14 -x LINEARID -x RTTYP

only drop features if the tiles get too big.

Tippecanoe will normally drop a fraction of point features at zooms below the maxzoom,

to keep the low-zoom tiles from getting too big. If you have a smaller data set where

all the points would fit without dropping any of them, use `-r1` to keep them all.

If you do want point dropping, but you still want the tiles to be denser than `-zg`

* `-L{`_layer-json_`}` or `--named-layer={`_layer-json_`}`: Specify an input file and layer options by a JSON object. The JSON object must contain a `"file"` key to specify the filename to read from. (If the `"file"` key is an empty string, it means to read from the standard input stream.) It may also contain a `"layer"` field to specify the name of the layer, and/or a `"description"` field to specify the layer's description in the tileset metadata, and/or a `"format"` field to specify `csv` or `geobuf` file format if it is not obvious from the `name`. Example:
|
||||
|
||||
```
|
||||
tippecanoe -z5 -o world.mbtiles -L'{"file":"ne_10m_admin_0_countries.json", "layer":"countries", "description":"Natural Earth countries"}'
|
||||
```
|
||||
|
||||
CSV input files currently support only Point geometries, from columns named `latitude`, `longitude`, `lat`, `lon`, `long`, `lng`, `x`, or `y`.
|
||||
|
||||
### Parallel processing of input
|
||||
|
||||
* `-P` or `--read-parallel`: Use multiple threads to read different parts of each GeoJSON input file at once.
|
||||
* `-P` or `--read-parallel`: Use multiple threads to read different parts of each input file at once.
|
||||
This will only work if the input is line-delimited JSON with each Feature on its
|
||||
own line, because it knows nothing of the top-level structure around the Features. Spurious "EOF" error
|
||||
messages may result otherwise.
|
||||
Performance will be better if the input is a named file that can be mapped into memory
|
||||
rather than a stream that can only be read sequentially.
|
||||
|
||||
If the input file begins with the [RFC 8142](https://tools.ietf.org/html/rfc8142) record separator,
|
||||
parallel processing of input will be invoked automatically, splitting at record separators rather
|
||||
than at all newlines.
|
||||
|
||||
Parallel processing will also be automatic if the input file is in Geobuf format.
|
||||
|
||||
### Projection of input
|
||||
|
||||
* `-s` _projection_ or `--projection=`_projection_: Specify the projection of the input data. Currently supported are `EPSG:4326` (WGS84, the default) and `EPSG:3857` (Web Mercator). In general you should use WGS84 for your input files if at all possible.
|
||||
* `-s` _projection_ or `--projection=`_projection_: Specify the projection of the input data. Currently supported are `EPSG:4326` (WGS84, the default) and `EPSG:3857` (Web Mercator).
|
||||
|
||||
### Zoom levels
|
||||
|
||||
* `-z` _zoom_ or `--maximum-zoom=`_zoom_: Maxzoom: the highest zoom level for which tiles are generated (default 14)
|
||||
* `-zg` or `--maximum-zoom=g`: Guess what is probably a reasonable maxzoom based on the spacing of features.
|
||||
* `-Z` _zoom_ or `--minimum-zoom=`_zoom_: Minzoom: the lowest zoom level for which tiles are generated (default 0)
|
||||
* `-ae` or `--extend-zooms-if-still-dropping`: Increase the maxzoom if features are still being dropped at that zoom level.
|
||||
The detail and simplification options that ordinarily apply only to the maximum zoom level will apply both to the originally
|
||||
specified maximum zoom and to any levels added beyond that.
|
||||
* `-R` _zoom_`/`_x_`/`_y_ or `--one-tile=`_zoom_`/`_x_`/`_y_: Set the minzoom and maxzoom to _zoom_ and produce only
|
||||
the single specified tile at that zoom level.

|
||||

||||

|
||||

### Filtering feature attributes
|
||||
|

* `-x` _name_ or `--exclude=`_name_: Exclude the named attributes from all features. You can specify multiple `-x` options to exclude several attributes. (Don't comma-separate names within a single `-x`.)
|
||||
* `-y` _name_ or `--include=`_name_: Include the named attributes in all features, excluding all those not explicitly named. You can specify multiple `-y` options to explicitly include several attributes. (Don't comma-separate names within a single `-y`.)
|
||||
* `-X` or `--exclude-all`: Exclude all attributes and encode only geometries
|
||||
|
||||
### Modifying feature attributes
|
||||
|
||||
* `-T`_attribute_`:`_type_ or `--attribute-type=`_attribute_`:`_type_: Coerce the named feature _attribute_ to be of the specified _type_.
|
||||
The _type_ may be `string`, `float`, `int`, or `bool`.
|
||||
If the type is `bool`, then original attributes of `0` (or, if numeric, `0.0`, etc.), `false`, `null`, or the empty string become `false`, and otherwise become `true`.
|
||||
If the type is `float` or `int` and the original attribute was non-numeric, it becomes `0`.
|
||||
If the type is `int` and the original attribute was floating-point, it is rounded to the nearest integer.
|
||||
* `-Y`_attribute_`:`_description_ or `--attribute-description=`_attribute_`:`_description_: Set the `description` for the specified attribute in the tileset metadata to _description_ instead of the usual `String`, `Number`, or `Boolean`.
|
||||
* `-E`_attribute_`:`_operation_ or `--accumulate-attribute=`_attribute_`:`_operation_: Preserve the named _attribute_ from features
|
||||
that are dropped, coalesced-as-needed, or clustered. The _operation_ may be
|
||||
`sum`, `product`, `mean`, `max`, `min`, `concat`, or `comma`
|
||||
to specify how the named _attribute_ is accumulated onto the attribute of the same name in a feature that does survive.
|
||||
* `-pe` or `--empty-csv-columns-are-null`: Treat empty CSV columns as nulls rather than as empty strings.
|
||||
* `-aI` or `--convert-stringified-ids-to-numbers`: If a feature ID is the string representation of a number, convert it to a plain number to use as the feature ID.
|
||||
* `--use-attribute-for-id=`*name*: Use the attribute with the specified *name* as if it were specified as the feature ID. (If this attribute is a stringified number, you must also use `-aI` to convert it to a number.)
|
||||
|
||||
### Filtering features by attributes
|
||||
|
||||
* `-j` *filter* or `--feature-filter`=*filter*: Check features against a per-layer filter (as defined in the [Mapbox GL Style Specification](https://docs.mapbox.com/mapbox-gl-js/style-spec/#other-filter)) and only include those that match. Any features in layers that have no filter specified will be passed through. Filters for the layer `"*"` apply to all layers. The special variable `$zoom` refers to the current zoom level.
|
||||
* `-J` *filter-file* or `--feature-filter-file`=*filter-file*: Like `-j`, but read the filter from a file.
|
||||
|
||||
Example: to find the Natural Earth countries with low `scalerank` but high `LABELRANK`:
|
||||
|
||||
```
|
||||
tippecanoe -z5 -o filtered.mbtiles -j '{ "ne_10m_admin_0_countries": [ "all", [ "<", "scalerank", 3 ], [ ">", "LABELRANK", 5 ] ] }' ne_10m_admin_0_countries.geojson
|
||||
```
|
||||
|
||||
Example: to retain only major TIGER roads at low zoom levels:
|
||||
|
||||
```
|
||||
tippecanoe -o roads.mbtiles -j '{ "*": [ "any", [ ">=", "$zoom", 11 ], [ "in", "MTFCC", "S1100", "S1200" ] ] }' tl_2015_06001_roads.json
|
||||
```
|
||||
|
||||
Tippecanoe also accepts expressions of the form `[ "attribute-filter", name, expression ]`, to filter individual feature attributes
|
||||
instead of entire features. For example, you can exclude the road names at low zoom levels by doing
|
||||
|
||||
```
|
||||
tippecanoe -o roads.mbtiles -j '{ "*": [ "attribute-filter", "FULLNAME", [ ">=", "$zoom", 9 ] ] }' tl_2015_06001_roads.json
|
||||
```
|
||||
|
||||
An `attribute-filter` expression itself is always considered to evaluate to `true` (in other words, to retain the feature instead
|
||||
of dropping it). If you want to use multiple `attribute-filter` expressions, or to use other expressions to remove features from
|
||||
the same layer, enclose them in an `all` expression so they will all be evaluated.
|
||||
* `-x` _name_ or `--exclude=`_name_: Exclude the named properties from all features
|
||||
* `-y` _name_ or `--include=`_name_: Include the named properties in all features, excluding all those not explicitly named
|
||||
* `-X` or `--exclude-all`: Exclude all properties and encode only geometries

### Dropping a fraction of features to keep under tile size limits
|

|
||||
* `-an` or `--drop-smallest-as-needed`: Dynamically drop the smallest features (physically smallest: the shortest lines or the smallest polygons) from each zoom level to keep large tiles under the 500K size limit. This option will not work for point features.
|
||||
* `-aN` or `--coalesce-smallest-as-needed`: Dynamically combine the smallest features (physically smallest: the shortest lines or the smallest polygons) from each zoom level into other nearby features to keep large tiles under the 500K size limit. This option will not work for point features, and will probably not help very much with LineStrings. It is mostly intended for polygons, to maintain the full original area covered by polygons while still reducing the feature count somehow. The attributes of the small polygons are *not* preserved into the combined features (except through `--accumulate-attribute`), only their geometry. Furthermore, the polygons to which nested polygons are coalesced may not necessarily be the immediately enclosing features.
|
||||
* `-aD` or `--coalesce-densest-as-needed`: Dynamically combine the densest features from each zoom level into other nearby features to keep large tiles under the 500K size limit. (Again, mostly useful for polygons.)
|
||||
* `-aS` or `--coalesce-fraction-as-needed`: Dynamically combine a fraction of features from each zoom level into other nearby features to keep large tiles under the 500K size limit. (Again, mostly useful for polygons.)
|
||||
* `-pd` or `--force-feature-limit`: Dynamically drop some fraction of features from large tiles to keep them under the 500K size limit. It will probably look ugly at the tile boundaries. (This is like `-ad` but applies to each tile individually, not to the entire zoom level.) You probably don't want to use this.
|
||||
* `-aC` or `--cluster-densest-as-needed`: If a tile is too large, try to reduce its size by increasing the minimum spacing between features, and leaving one placeholder feature from each group. The remaining feature will be given a `"clustered": true` attribute to indicate that it represents a cluster, a `"point_count"` attribute to indicate the number of features that were clustered into it, and a `"sqrt_point_count"` attribute to indicate the relative width of a feature to represent the cluster. If the features being clustered are points, the representative feature will be located at the average of the original points' locations; otherwise, one of the original features will be left as the representative.

|
||||
* `-ac` or `--coalesce`: Coalesce consecutive features that have the same attributes. This can be useful if you have lots of small polygons with identical attributes and you would like to merge them together.
|
||||
* `-ao` or `--reorder`: Reorder features to put ones with the same attributes in sequence (instead of ones that are approximately spatially adjacent), to try to get them to coalesce. You probably want to use this if you use `--coalesce`.
|
||||
* `-ao` or `--reorder`: Reorder features to put ones with the same properties in sequence, to try to get them to coalesce. You probably don't want to use this.

### Adding calculated attributes

||||
|
||||
* `-ag` or `--calculate-feature-density`: Add a new attribute, `tippecanoe_feature_density`, to each feature, to record how densely features are spaced in that area of the tile. You can use this attribute in the style to produce a glowing effect where points are densely packed. It can range from 0 in the sparsest areas to 255 in the densest.
|
||||
* `-ai` or `--generate-ids`: Add an `id` (a feature ID, not an attribute named `id`) to each feature that does not already have one. There is currently no guarantee that the `id` added will be stable between runs or that it will not conflict with manually-assigned feature IDs. Future versions of Tippecanoe may change the mechanism for allocating IDs.

|
||||
* `-pC` or `--no-tile-compression`: Don't compress the PBF vector tile data. If you are getting "Unimplemented type 3" error messages from a renderer, it is probably because it expects uncompressed tiles using this option rather than the normal gzip-compressed tiles.

### Filters

|
||||
* `-c` _command_ or `--postfilter=`_command_: Specify a shell filter command to be run at the end of assembling each tile
|
||||
|
||||
The pre- and post-filter commands allow you to do optional filtering or transformation on the features of each tile
|
||||
as it is created. They are shell commands, run with the zoom level, X, and Y as the `$1`, `$2`, and `$3` arguments.
|
||||
Future versions of Tippecanoe may add additional arguments for more context.
|
||||
|
||||
The features are provided to the filter
|
||||
as a series of newline-delimited GeoJSON objects on the standard input, and `tippecanoe` expects to read another
|
||||
set of GeoJSON features from the filter's standard output.
|
||||
|
||||
The prefilter receives the features at the highest available resolution, before line simplification,
|
||||
polygon topology repair, gamma calculation, dynamic feature dropping, or other internal processing.
|
||||
The postfilter receives the features at tile resolution, after simplification, cleaning, and dropping.
|
||||
|
||||
The layer name is provided as part of the `tippecanoe` element of the feature and must be passed through
|
||||
to keep the feature in its correct layer. In the case of the prefilter, the `tippecanoe` element may also
|
||||
contain `index`, `sequence`, `extent`, and `dropped`, elements, which must be passed through for internal operations like
|
||||
`--drop-densest-as-needed`, `--drop-smallest-as-needed`, and `--preserve-input-order` to work.

tile-join
|
||||
=========
|
||||
|
||||
Tile-join is a tool for copying and merging vector mbtiles files and for
|
||||
joining new attributes from a CSV file to existing features in them.
|
||||
Tile-join is a tool for joining new attributes from a CSV file to features that
|
||||
have already been tiled with tippecanoe. It reads the tiles from an existing .mbtiles
|
||||
file, matches them against the records of the CSV, and writes out a new tileset.
|
||||
|
||||
It reads the tiles from an
|
||||
existing .mbtiles file or a directory of tiles, matches them against the
|
||||
records of the CSV (if one is specified), and writes out a new tileset.
|
||||
|
||||
If you specify multiple source mbtiles files or source directories of tiles,
|
||||
all the sources are read and their combined contents are written to the new
|
||||
mbtiles output. If they define the same layers or the same tiles, the layers
|
||||
or tiles are merged.
|
||||
If you specify multiple source mbtiles files, they are all read and their combined
|
||||
contents are written to the new mbtiles output. If they define the same layers or
|
||||
the same tiles, the layers or tiles are merged.
|
||||
|
||||
The options are:
|
||||
|
||||
### Output tileset
|
||||
|
||||
* `-o` *out.mbtiles* or `--output=`*out.mbtiles*: Write the new tiles to the specified .mbtiles file.
|
||||
* `-e` *directory* or `--output-to-directory=`*directory*: Write the new tiles to the specified directory instead of to an mbtiles file.
|
||||
* `-f` or `--force`: Remove *out.mbtiles* if it already exists.
|
||||
|
||||
### Tileset description and attribution
|
||||
|
||||
* `-A` *attribution* or `--attribution=`*attribution*: Set the attribution string.
|
||||
* `-n` *name* or `--name=`*name*: Set the tileset name.
|
||||
* `-N` *description* or `--description=`*description*: Set the tileset description.
|
||||
|
||||
### Layer filtering and naming
|
||||
|
||||
* `-l` *layer* or `--layer=`*layer*: Include the named layer in the output. You can specify multiple `-l` options to keep multiple layers. If you don't specify, they will all be retained.
|
||||
* `-L` *layer* or `--exclude-layer=`*layer*: Remove the named layer from the output. You can specify multiple `-L` options to remove multiple layers.
|
||||
* `-R`*old*`:`*new* or `--rename-layer=`*old*`:`*new*: Rename the layer named *old* to be named *new* instead. You can specify multiple `-R` options to rename multiple layers. Renaming happens before filtering.
|
||||
|
||||
### Zoom levels
|
||||
|
||||
* `-z` _zoom_ or `--maximum-zoom=`_zoom_: Don't copy tiles from higher zoom levels than the specified zoom
|
||||
* `-Z` _zoom_ or `--minimum-zoom=`_zoom_: Don't copy tiles from lower zoom levels than the specified zoom
|
||||
|
||||
### Merging attributes from a CSV file
|
||||
|
||||
* `-c` *match*`.csv` or `--csv=`*match*`.csv`: Use *match*`.csv` as the source for new attributes to join to the features. The first line of the file should be the key names; the other lines are values. The first column is the one to match against the existing features; the other columns are the new data to add.
|
||||
|
||||
### Filtering features and feature attributes
|
||||
|
||||
* `-x` *key* or `--exclude=`*key*: Remove attributes of type *key* from the output. You can use this to remove the field you are matching against if you no longer need it after joining, or to remove any other attributes you don't want.
|
||||
* `-X` or `--exclude-all`: Remove all attributes from the output.
|
||||
* `-i` or `--if-matched`: Only include features that matched the CSV.
|
||||
* `-j` *filter* or `--feature-filter`=*filter*: Check features against a per-layer filter (as defined in the [Mapbox GL Style Specification](https://docs.mapbox.com/mapbox-gl-js/style-spec/#other-filter)) and only include those that match. Any features in layers that have no filter specified will be passed through. Filters for the layer `"*"` apply to all layers.
|
||||
* `-J` *filter-file* or `--feature-filter-file`=*filter-file*: Like `-j`, but read the filter from a file.
|
||||
* `-pe` or `--empty-csv-columns-are-null`: Treat empty CSV columns as nulls rather than as empty strings.
|
||||
|
||||
### Setting or disabling tile size limits
|
||||
|
||||
* `-pk` or `--no-tile-size-limit`: Don't skip tiles larger than 500K.
|
||||
* `-pC` or `--no-tile-compression`: Don't compress the PBF vector tile data.
|
||||
* `-pg` or `--no-tile-stats`: Don't generate the `tilestats` row in the tileset metadata. Uploads without [tilestats](https://github.com/mapbox/mapbox-geostats) will take longer to process.
|
||||
* `-o` *out.mbtiles*: Write the new tiles to the specified .mbtiles file
|
||||
* `-f`: Remove *out.mbtiles* if it already exists
|
||||
* `-c` *match*`.csv`: Use *match*`.csv` as the source for new attributes to join to the features. The first line of the file should be the key names; the other lines are values. The first column is the one to match against the existing features; the other columns are the new data to add.
|
||||
* `-x` *key*: Remove attributes of type *key* from the output. You can use this to remove the field you are matching against if you no longer need it after joining, or to remove any other attributes you don't want.
|
||||
* `-i`: Only include features that matched the CSV.
|
||||
* `-pk`: Don't skip tiles larger than 500K.
|
||||
* `-l` *layer*: Include the named layer in the output. You can specify multiple `-l` options to keep multiple layers. If you don't specify, they will all be retained.
|
||||
* `-L` *layer*: Remove the named layer from the output. You can specify multiple `-L` options to remove multiple layers.

tippecanoe-json-tool
|
||||
====================
|
||||
|
||||
Extracts GeoJSON features or standalone geometries as line-delimited JSON objects from a larger JSON file,
|
||||
following the same extraction rules that Tippecanoe uses when parsing JSON.
|
||||
|
||||
tippecanoe-json-tool file.json [... file.json]
|
||||
|
||||
Optionally also wraps them in a FeatureCollection or GeometryCollection as appropriate.
|
||||
|
||||
Optionally extracts an attribute from the GeoJSON `properties` for sorting.
|
||||
|
||||
Optionally joins a sorted CSV of new attributes to a sorted GeoJSON file.
|
||||
|
||||
The reason for requiring sorting is so that it is possible to work on CSV and GeoJSON files that are larger
|
||||
than can comfortably fit in memory by streaming through them in parallel, in the same way that the Unix
|
||||
`join` command does. The Unix `sort` command can be used to sort large files to prepare them for joining.
|
||||
|
||||
The sorting interface is weird, and future version of `tippecanoe-json-tool` will replace it with
|
||||
something better.
|
||||
|
||||
### Options
|
||||
|
||||
* `-w` or `--wrap`: Add the FeatureCollection or GeometryCollection wrapper.
|
||||
* `-e` *attribute* or `--extract=`*attribute*: Extract the named attribute as a prefix to each feature.
|
||||
The formatting makes excessive use of `\u` quoting so that it follows JSON string rules but will still
|
||||
be sorted correctly by tools that just do ASCII comparisons.
|
||||
* `-c` *file.csv* or `--csv=`*file.csv*: Join attributes from the named sorted CSV file, using its first column as the join key. Geometries will be passed through even if they do not match the CSV; CSV lines that do not match a geometry will be discarded.
|
||||
* `-pe` or `--empty-csv-columns-are-null`: Treat empty CSV columns as nulls rather than as empty strings.

|
||||
* `-t` _projection_: Specify the projection of the output data. Currently supported are EPSG:4326 (WGS84, the default) and EPSG:3857 (Web Mercator).
