Alternatives to GeometryService for projection

jackcrawford — Tue, 03 Jul 2018 04:48:47 GMT

I'm new to ArcGIS. is there an code-only alternative to using the REST Geometry service to perform operations on geometry, e.g. projection, determine an envelope or must I use the geometry service. This is not a mapping app but will run on a Java servlet engine. Need to project multipolygons and polygons (in ESRI JSON format) from SR NAD83 4269 to WGS84 3857 and determine envelope for same.

Thanks for the help.

Dear Jack,

Yes, there are some options:

1) Use ProjectEngine in ArcGIS Runtime for Java. However, Runtime was not designed to work with servlet engine.

GeometryEngine| arcgis-java

2) Use open - source libraries to perform geometry operations like GitHub - locationtech/jts: The JTS Topology Suite is a Java library for creating and manipulating vector geometry. and integrate it with your application

3) Use Esri JS Geometry Engine and call Javascript from your application geometryEngine | API Reference | ArcGIS API for JavaScript 4.8

Hope it helps,

Adam
