dans-gdal-scripts

This package consists of a number of utilities for use in conjunction with GDAL. Currently these programs are only supported on Unix systems, but it should be possible to compile them on Windows if you know how to make the corresponding Makefiles.

Programs

gdal_contrast_stretch

Contrast stretch and conversion from 8,16-bit or floating point to 8-bit

gdal_dem2rgb

Generate hillshaded images from DEMs

gdal_get_projected_bounds

Project a polygon and return its bounding rectangle

gdal_landsat_pansharp

Pansharpening - works best for Landsat 7 images

gdal_list_corners

Prints raster geocode information in YAML format (similar to gdalinfo but gives YAML)

gdal_merge_simple

Merge individual bands into a single GeoTIFF image (8-bit only)

gdal_merge_vrt

Merge individual bands into a single VRT image

gdal_raw2geotiff

Convert raw binary files into GeoTIFFs

gdal_trace_outline

Trace the outline of an image and generate WKT or Shapefile (options exist for cleaning up raggedy edges, can also do feature classification)

gdal_wkt_to_mask

Generate a bitmap of the area covered by a polygon
