# GIS and Weather Data Processing Container Plan
|
|
|
|
## Overview
|
|
This document outlines the plan for creating Docker containers to handle GIS data processing and weather data analysis. These containers will be used exclusively in CTO mode for R&D and data analysis tasks, with integration to documentation workflows and MinIO for data output.
|
|
|
|
## Requirements
|
|
|
|
### GIS Data Processing
|
|
- Support for Shapefiles and other GIS formats
|
|
- Self-hosted GIS stack (not Google Maps or other commercial services)
|
|
- Integration with tools like GDAL, Tippecanoe, DuckDB
|
|
- Heavy use of PostGIS database
|
|
- Parquet format support for efficient data storage
|
|
- Based on reference workflows from:

|
|
- Complex dependency management, especially with DuckDB and PostGIS
|
|
- Computational resource requirements, especially for large datasets
|
|
