I have a map in pdf format. i want to import the map in grass. reading
pdf map is available in ArcGIS. so I thought of developing and
contributing a module to GRASS GIS (r.in.pdf) to read maps in pdf formats
directly.I dont know where to start.
maybe use the very nice "pdftk" program to extract the single page you
want from the document, and then extract the inner PostScript from within
the PDF wrapper. Then use graphics tools as others have suggested, or
ps -> vector format directly for non-raster.
will anyone please provide me any information or links related to
importing raster maps into grass gis.how a map is processed when we
perform r.in.* module on the map?. How files are like cellhd,fcell etc
are created in GRASS?
use r.in.gdal or one of the existing r.in.* low-level modules to do that.
there's not much need or point to (re)doing it yourself.
good luck,
