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.
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.
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.
- -lyr_name <name>
Layer name to create/append to in the output tile 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.
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
raster_common_options for other command-line options, and in particular the --optfile switch that can be used to specify a list of input datasets.
