                  [-lyr_name name] index_file [gdal_file]*

DESCRIPTION

       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.

       -lyr_name <name>
              Layer name to create/append to in the output tile index file.

       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.

EXAMPLES

       • 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.
