Gina Tools

This package consists of a number of utilities for use in conjunction with GDAL. Currently these programs are only supported on Unix systems.

gdal_contrast_stretch	Contrast stretch and conversion from 16-bit 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
