Are we sure GeoTools and ESRI geometry-api have the same GeoJSON in mind? I would look at *test cases* for the GeoTools functionality. Where possible I always try and get the docs to include example code directly from test cases (so it is not out of date).
The geojson module is unsupported, so while it compiles it may not run? Kind of surprising this has not been popular enough to be completed 🙂 There isa specific GeometryJSONTest <https://github.com/geotools/geotools/blob/main/modules/unsupported/geojson/src/test/java/org/geotools/geojson/GeometryJSONTest.java> that appears to have examples of using Geometry in isolation (not writing to a file). -- Jody Garnett On May 15, 2024 at 9:39:27 PM, Phil Scadden <p.scad...@gns.cri.nz> wrote: > Ultimately, what I am trying to do is read some features from a geopkg > using geotools, fidding with contents of the feature and then writing the > Feature to an ESRI FeatureServer using the REST API.
