gdaltindex - Builds a shapefile as a raster tileindex.
gdaltindex [-f format] [-tileindex field_name] [-write_absolute_path]
[-skip_different_projection] [-t_srs target_srs]
[-src_srs_name field_name] [-src_srs_format [AUTO|WKT|EPSG|PROJ]
[-lyr_name name] index_file [gdal_file]*
This program creates an OGR-supported dataset 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.
- -f <format>
- The OGR format of the output tile index file. Starting with GDAL 2.3, if
not specified, the format is guessed from the extension (previously was
ESRI Shapefile).
- -tileindex
<field_name>
- The output field name to hold the file path/location to the indexed
rasters. The default tile index field name is location.
- -write_absolute_path
- The absolute path to the raster files is stored in the tile index file. By
default the raster filenames will be put in the file exactly as they are
specified on the command line.
- -skip_different_projection
- Only files with same projection as files already inserted in the tileindex
will be inserted (unless -t_srs is specified). Default does not
check projection and accepts all inputs.
- -t_srs
<target_srs>:
- Geometries of input files will be transformed to the desired target
coordinate reference system. Default creates simple rectangular polygons
in the same coordinate reference system as the input rasters.
- -src_srs_name
<field_name>
- The name of the field to store the SRS of each tile. This field name can
be used as the value of the TILESRS keyword in MapServer
- -src_srs_format
<type>
- The format in which the SRS of each tile must be written. Types can be
AUTO, WKT, EPSG, PROJ.
- index_file
- The name of the output file to create/append to. The default dataset will
be created if it doesn't already exist, otherwise it will append to the
existing dataset.
- <gdal_file>
- The input GDAL raster files, can be multiple files separated by spaces.
Wildcards my also be used. Stores the file locations in the same style as
specified here, unless -write_absolute_path option is also
used.
- •
- Produce a shapefile (doq_index.shp) with a record for every image
that the utility found in the doq folder. Each record holds
information that points to the location of the image and also a bounding
rectangle shape showing the bounds of the image:
gdaltindex doq_index.shp doq/*.tif
- •
- Perform the same command as before, but now we create a GeoPackage instead
of a Shapefile.
gdaltindex -f GPKG doq_index.gpkg doq/*.tif
- •
- The -t_srs option can also be used to transform all input rasters
into the same output projection:
gdaltindex -t_srs EPSG:4326 -src_srs_name src_srs tile_index_mixed_srs.shp *.tif
- •
- Make a tile index from files listed in a text file :
gdaltindex doq_index.shp --optfile my_list.txt
Common options for raster programs for other command-line
options, and in particular the --optfile switch that can be used to
specify a list of input datasets.
