NAME¶
gdaltindex - gdaltindex builds a shapefile as a raster tileindex
SYNOPSIS¶
gdaltindex [-tileindex field_name] [-write_absolute_path] [-skip_different_projection] [-t_srs target_srs] index_file [gdal_file]*
DESCRIPTION¶
This program builds a shapefile with a record for each input raster file, an
attribute containing the filename, and a polygon geometry outlining the
raster. This output is suitable for use with MapServer as a raster tileindex.
- •
- The shapefile (index_file) will be created if it doesn't already exist,
otherwise it will append to the existing file.
- •
- The default tile index field is 'location'.
- •
- Raster filenames will be put in the file exactly as they are specified on
the commandline unless the option -write_absolute_path is used.
- •
- If -skip_different_projection is specified, only files with same
projection ref as files already inserted in the tileindex will be inserted
(unless t_srs is specified).
- •
- If -t_srs is specified, geometries of input files will be transformed to
the desired target coordinate reference system. Note that using this
option generates files that are NOT compatible with MapServer.
- •
- Simple rectangular polygons are generated in the same coordinate reference
system as the rasters, or in target reference system if the -t_srs option
is used.
