CommunityOpen-source Java GIS toolkit for full spatial dev
System Documentation
What problem does it solve?
Java-based GIS development can be complex due to fragmented libraries for data access, CRS conversions, spatial queries, and rendering. GeoTools provides a mature, modular toolkit that unifies vector and raster I/O, CRS transformations, filtering, and map rendering in a compliant, reuse-ready package.
Core Features & Use Cases
- Vector and raster data access via DataStore and readers, supporting formats like Shapefile, GeoPackage, GeoJSON, PostGIS, and more.
- Coordinate reference systems (CRS) handling and transformations using EPSG-aware utilities for accurate geospatial math.
- Spatial querying and filtering with CQL/ECQL, including bbox, contains, intersects, and attribute-based queries.
- Map rendering and styling support for producing maps, charts, and export formats like PNG or SVG.
- Web service clients for WMS/WFS/WCS integration and desktop/server GIS workflows, enabling end-to-end GIS pipelines.
Use cases: building GIS portals, desktop GIS tools, or server-side geospatial services that require robust, standards-compliant data access and rendering.
Quick Start
Add GeoTools to your Maven or Gradle project and start building GIS-enabled Java applications using DataStore, CRS utilities, and rendering tools.
