Pacific Northwest LIDAR comes in esri .e00 format. To get it into a usable form
|
|
we can use gdal tools.
|
|
|
|
Reproject the source data to EPSG:4326 (GRS84, lat/long)
|
|
gdalwarp -t_srs EPSG:4326 -of GS7BG -ot Float64 srcfile.e00 destfile.xyz
|
|
|
|
[user@host ~]$ gdalwarp -t_srs EPSG:4326 -of GS7BG -ot Float64 ~/q47122a71.e00 ~/q47122a71.xyz
|
|
|
|
Convert the intermedatry file to AAIGrid Int32
|
|
gdal_translate -of AAIGrid -ot Int32 srcfile.xyz destfile.asc
|
|
|
|
[user@host ~]$ gdal_translate -of AAIGrid -ot Int32 ~/q47122a71.xyz ~/q47122a71.asc
|
|
|
|
The above could be pipelined to reduce intermedaty files.
