Re: [Bigdata-commit] Using the Geospatial service

[Michael S. <ms...@me...>]

Dear Blaise,

thanks for your interest in using geospatial. Unless I oversee something, data and query look good. So I guess what’s missing is that you need to enable geospatial when creating the namespace:

> com.bigdata.rdf.store.AbstractTripleStore.geoSpatial=true

Please note that the geospatial feature in 2.0.1 was intended to be a preview — while it should work well performance-wise, we’re just finishing up a much more powerful version of the geospatial feature for 2.1, which comes with more powerful configuration mechanisms, a built-in datatype for lat+lon only, and many more (this will, unfortunately, include breaking changes, yet it should be pretty straightforward to migrate existing geospatial knowledge bases to 2.0.2).

Best,
Michael
