NAME
gdaltindex - Builds a shapefile as a raster tileindex.
SYNOPSIS
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]*
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 in-
dexed rasters. The default tile index field name is location.
-write_absolute_path
The absolute path to the raster files is stored in the tile in-
dex 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 rec-
tangular 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 informa-
tion 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.
