> Some of your documentation is 404ing. Thanks, will fix momentarily! EDIT: fixed, thanks! > How many dimensions are supported? Two dimensions. The commands are designed primarily with Earth geometry in mind to help people build location-aware apps. > Also, does this support many projections, or just a few. It supports WGS84 (a commonly used ellipsoid model) or a unit sphere. Currently you can't use a plane. Check out http://rethinkdb.com/api/javascript/get_nearest/ http://rethinkdb.com/api/javascript/get_nearest/ for an example. > Does this do a correct interpolation of degrees to meters along the path The implementation is based on the S2 library (https://code.google.com/p/s2-geometry-library/ https://code.google.com/p/s2-geometry-library/) also used by PostGIS, which AFAIK does spherical linear interpolation. > Are there commands to export WKT or WKB? No, currently only GeoJSON (which you could later post-process and export to other formats with existing tools). This is a great idea, though, if there is more demand for it we'll definitely add other exporters. EDIT: all great questions, I opened an issue in the doc repo (https://github.com/rethinkdb/docs/issues/521 https://github.com/rethinkdb/docs/issues/521) -- we'll address all of these in the docs.
