[GRASS-user] Wich file format to transport (raster/ vector) data from a GRASS db in to another computer's GRASS db? Why export vector data in shapefile for starspan/ OpenEV?
Dear all, it's some months now that I am trying to learn GRASS-GIS and I wonder 1. if one needs to copy some GRASS raster data from his data base in another computer's GRASS data base (same coordinate system of course), then how? Where do for example the history files go? I understand (I think) the need to set-up properly a LOCATION and import the data. But why isn't there a GRASS portable vector/ raster file format? 2. the same about vector data 3. Is it really necessaty to export in shapefiles when working with starspan? If there is GRASS read-only support by OGR why is it necessary to export? What about OpenEV? If GDAL is built with GRASS support why can't it read GRASS rasters?

1.. if one needs to copy some GRASS raster data from his data base in another computer's GRASS data base (same coordinate system of course), then how? Where do for example the history files go? See r.pack/r.unpack in the Grass Add-ons. I use these scripts for moving rasters around from computer to computer: http://grass.gdf-hannover.de/wiki/GRASS_AddOns#Raster_add-ons The r.pack script uses a MatLab format file as an intermediary, and is apparently a decent universal format for storing rasters in. I understand (I think) the need to set-up properly a LOCATION and import the data. But why isn't there a GRASS portable vector/ raster file format? I think r.in/out.ascii and v.in/out.ascii are designed for this? Not 100% sure, but check the man pages for these two commands. 2. the same about vector data See above. 3. Is it really necessaty to export in shapefiles when working with starspan? If there is GRASS read-only support by OGR why is it necessary to export? I can't comment on Starspan; never used it.

[GRASS-user] newbie category question..
Hi - I'm trying to do something I thought was fairly simple, but eludes me... I'm trying to find the average elevation of polygons. I used gdal_rasterize to make a layer, which does indeed have unique categories, and values, for each building. I'm trying to use this layer against a DEM, and on a per-polygon basis, get the min/max of the DEM ... I was thinking that somehow I might use r.statistics, butnot so straightforward, apparently. thanks in advance for any suggestions! Chris p.s. - it would sure be nice if I could make key/value pairs within mapcalc; that way I could read a category from one layer, make a key, and fetch it anywhere within mapcalc... ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
