I'm using gdalwarp to clip a number of geotiffs (tiles of a larger map) to a polygon described by a shapefile (which is about the size of the overall map, i.e. much larger than individual tiles) ...
I'm generating contours from four 5x5 degree SRTM DEMs in southeastern Australia. I'm using gdalwarp to reproject the DEM, then gdal_contour to generate contours. First, I generated contours for each ...
I need to perform some tests and verifications on databases and/or datasets. I need for example to analyze two databases and then determine if there is enough correlation between both. My main issue ...
I need to colorized geometries from shapefiles and convert them to raster image (geotiff). I tried to use geotools's VectorToRasterProcess and ImageWorker ("d:\gis\tmp\32 27 25 w4.shp" is path to my ...
Given a geotiff image with a colortable in it, what is the easiest way to extract each color as its own "layer or shapefile or multipolygon object"? Specifically, I am looking for a programmatic ...
