[kepler-dev] Kepler vs Grass

[Dan Higgins]

Bertram,
    We have been looking a Grass (and other GIS systems) in particular 
as part of the BEAM GARP/ENM work (and I am the main developer for 
this). Due to its size, we (at least temporarily) decided not to try 
integrating all of Grass. For the GARP workflows we needed only a few 
Grass functions. So, Jianting at UNM/LTER pulled a few routines out of 
Grass and turned them into actors (Convex Hull, Rasterization, etc). We 
also needed some import of GIS files, so the GDAL module (part of Grass) 
has also been turned into an actor.  We also created some pure java GIS 
actors for manipulating raster grids, etc. A image display system 
(ImageJ) was also used for displaying various spatial data. So there are 
GIS actors that already exist and we are planning on adding others as 
specifically needed. [Also, Efrat has/is adding a number of GIS features 
through web services.]

    Examples of many of these existing features can be found by clicking 
on the "ENM(GARP) Workflows" link which is the first link on the current 
Kepler intro screen. Take a look at the "Rescaling Example" or the 
"Convex Hull Operations" example.
