[kepler-dev] GIS i/o

[Matt Jones]

Kepler has a nice collection of actors that can manipulate spatial data, 
including for example GDAL's warp and project, convex hull operations, 
and various point in polygon and similar query operators.  We've wrapped 
some of the GRASS library functions as GIS actors in Kepler too, and we 
have access to R in Kepler which has a whole suite of geospatial 
functions.

That said, we haven't done what you asked for, which is to provide a 
link to a specific GIS system where we can manipulate that system (like 
create new layers). As GIS systems are somewhat proprietary, it would 
probably be best to provide data read/write actors for the OGC services, 
and maybe an interface to a backend spatial data system like PostGIS. 
Then the GIS system and kepler could both access the same spatial data 
stores via OGC or other standard interfaces.

If you do something in this area it would be of great interest to us on 
SEEK and Kepler.
