arcgis-compressed-geometry

A Java library for encoding and decoding ArcGIS Compressed Geometry Format.

Introduction

This library provides encoding and decoding functionality for ArcGIS Compressed Geometry Format. It supports the following coordinate formats:

• xy (2D coordinates)
• xyz (3D coordinates with elevation)
• xym (coordinates with measure values)
• xyzm (coordinates with elevation and measure values)

How to use

Encode

List<double[]> coordinates = Arrays.asList(
            new double[]{-122.40645857695421, 37.78272915354862},
            new double[]{-122.40609876765315, 37.78299901052442}, 
            new double[]{-122.40597283439777, 37.78305298191958},
            new double[]{-122.40417378789242, 37.7844382477287}
        );
String geometry = CompressedGeometryEncoder.encode(coordinates, "xy", 55585);

Decode

List<double[]> points = CompressedGeometryDecoder.decode("+1m91-6fkfr+202tp+k+f+7+3+34+2d");
