ASF GitHub Bot commented on DRILL-4091: --------------------------------------- Github user k255 commented on the issue: https://github.com/apache/drill/pull/258 It's good that now there's commiter which is aware of the GIS context! The list of functions added in this PR is as follows: ST_Buffer, ST_Contains, ST_Crosses, ST_Difference, ST_Disjoint, ST_DiST_ance, ST_Envelope, ST_Equals, ST_Intersects, ST_Overlaps, ST_Relate, ST_Touches, ST_Transform, ST_Union, ST_UnionAggregate, ST_X, ST_Y, ST_XMin, ST_XMax, ST_YMin, ST_YMax Regarding the documentation, I wouldn't like to duplicate it because I followed what is available in PostGIS (which actually uses GEOS lib, in similar way as drill-gis uses relevant java libs - esri, proj4j) and these are defined in open geospatial consortium (OGC) specs. Of course here we have just a subset of what PostGIS is capable of, but I think it's valuable subset. So i.e. for ST_X function the docs are at http://www.postgis.net/docs/ST_X.html Also on example usage please refer to examples contained in readme at: https://github.com/k255/drill-gis I'll also finally need to think about blog post/presentation on this extension, but most probably not in following days but later in the future. > Support more functions in gis contrib module > -------------------------------------------- > > Key: DRILL-4091 > URL: https://issues.apache.org/jira/browse/DRILL-4091 > Project: Apache Drill > Issue Type: Improvement > Components: Functions - Drill > Reporter: Karol Potocki > > Support for commonly used gis functions in gis contrib module: relate, > contains, crosses, intersects, touches, difference, disjoint, buffer, union > etc. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
