Readme

go-geom

Package geom implements efficient geometry types for geospatial applications.

Key features

OpenGeo Consortium-style geometries.
Support for 2D and 3D geometries, measures (time and/or distance), and unlimited extra dimensions.
Encoding and decoding of common geometry formats (GeoJSON, KML, WKB, and others) including sql.Scanner and driver.Value interface implementations for easy database integration.
2D and 3D topology functions.
Efficient, cache-friendly internal representation.
Optional protection against malicious or malformed inputs.

Examples

PostGIS, EWKB, and GeoJSON.

Detailed features

Geometry types

Encoding and decoding

GeoJSON
IGC
KML (encoding only)
WKB
EWKB
WKT (encoding only)
WKB Hex
EWKB Hex

Geometry functions

XY 2D geometry functions
XYZ 3D geometry functions

Protection against malicious or malformed inputs

The WKB and EWKB formats encode geometry sizes, and memory is allocated for those geometries. If the input is malicious or malformed, the memory allocation can be very large, leading to a memory starvation denial-of-service attack against the server. For example, a client might send a MultiPoint with header indicating that it contains 2^32-1 points. This will result in the server reading that geometry to allocate 2 × sizeof(float64) × (2^32-1) = 64GB of memory to store those points. By default, malicious or malformed input protection is disabled, but can be enabled by setting positive values for wkbcommon.MaxGeometryElements.
