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, or as input for the GTI driver.

     TIP:
	Equivalent in new "gdal" command line interface:

	See gdal raster index.

     --help
	    Show this help message and exit

     --help-general
	    Gives a brief usage message for the generic GDAL commandline options
	    and exit.

     -q, --quiet
	    Suppress progress messages and other non-error output.

     -overwrite
	    Added in version 3.9.

	    Overwrite the tile index if it already exists.

     -recursive
	    Added in version 3.9.

	    Whether directories specified in <file_or_dir>  should  be	explored
	    recursively.

     -filename_filter <val>
	    Added in version 3.9.

	    Pattern  that  the	filenames  contained  in  directories pointed by
	    <file_or_dir> should follow.   '*'	is  a  wildcard  character  that
	    matches  any number of any characters including none. '?' is a wild-
	    card character that matches a  single  character.	Comparisons  are
	    done in a case insensitive way.  Several filters may be specified.

	    For example :-filename_filter "*.tif" -filename_filter "*.tiff"

     -min_pixel_size <val>
	    Added in version 3.9.

	    Minimum  pixel  size in term of geospatial extent per pixel (resolu-
	    tion) that a raster should have to be selected. The  pixel	size  is
	    evaluated after reprojection of its extent to the target SRS defined
	    by -t_srs.

     -max_pixel_size <val>
	    Added in version 3.9.

	    Maximum  pixel  size in term of geospatial extent per pixel (resolu-
	    tion) that a raster should have to be selected. The  pixel	size  is
	    evaluated after reprojection of its extent to the target SRS defined
	    by -t_srs.

     -of <output_format>
	    The  OGR format of the output tile index file. If not specified, the
	    format is guessed from the extension.

     -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  ex-
	    actly 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 {AUTO|WKT|EPSG|PROJ}
	    The format in which the SRS of each tile must be written. Types  can
	    be	AUTO, WKT, EPSG, PROJ.	This option should be used together with
	    -src_srs_format.

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

     -lco <NAME>=<VALUE>
	    Added in version 3.9.

	    Layer creation option (format specific)

     <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  ap-
	    pend to the existing dataset.

     <file_or_dir>
	    The  input	GDAL  raster  files,  can be multiple files separated by
	    spaces.  Wildcards may also be used. Stores the  file  locations  in
	    the same style as specified here, unless -write_absolute_path option
	    is also used.

	    Starting  with  GDAL  3.9,	this  can  also  be  a	directory  name.
	    -recursive can also be used to recurse down to sub-directories.

	    It is also possible to use the generic option --optfile filelist.txt
	    to specify a list of source files.

OPTIONS SPECIFIC TO USE BY THE GDAL GTI DRIVER
     gdaltindex can be used to generate a tile index suitable for use by the GTI
     driver. There are two possibilities:

     * either use directly a vector tile index generated by  gdaltindex  as  the
       input of the GTI driver

     * or  generate  a	small  XML  .gti  wrapper  file,  for  easier  use  with
       non-file-based formats such as databases, or for vector formats	that  do
       not support setting layer metadata items.

     Formats  that support layer metadata are for example GeoPackage (-of GPKG),
     FlatGeoBuf (-of FlatGeoBuf) or PostGIS (-of PG)

     Setting -tr and -ot is recommended to avoid the GTI driver to have  to  de-
     duce  them by opening the first tile in the index. If the tiles have nodata
     or mask band,  -nodata and -mask should also be set.

     In a GTI context, the extent of all tiles referenced in the tile index must
     be expressed in a single SRS. Consequently, if input tiles may have differ-
     ent SRS, either -t_srs or -skip_different_projection should be specified.

     -gti_filename <name>
	    Added in version 3.9.

	    Filename of the XML Virtual Tile Index file to generate, that can be
	    used as an input for the GDAL GTI / Virtual Raster Tile  Index  dri-
	    ver.   This  can  be  useful when writing the tile index in a vector
	    format that does not support writing layer metadata items.

     -tr <xres> <yres>
	    Added in version 3.9.

	    Target resolution in SRS unit per pixel.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or as RESX and RESY layer metadata items for  formats  that  support
	    layer metadata.

     -te <xmin> <ymin> <xmax> <ymax>
	    Added in version 3.9.

	    Target extent in SRS unit.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or	as  MINX,  MINY,  MAXX and MAXY layer metadata items for formats
	    that support layer metadata.

     -ot <datatype>
	    Added in version 3.9.

	    Data type of the tiles of the tile index: Byte, Int8, UInt16, Int16,
	    UInt32, Int32, UInt64,  Int64,  Float32,  Float64,	CInt16,  CInt32,
	    CFloat32 or CFloat64

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or	as  DATA_TYPE layer metadata item for formats that support layer
	    metadata.

     -bandcount <val>
	    Added in version 3.9.

	    Number of bands of the tiles of the tile index.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or as BAND_COUNT layer metadata item for formats that support  layer
	    metadata.

	    A  mix  of	tiles with N and N+1 bands is allowed, provided that the
	    color interpretation of the (N+1)th band is  alpha.  The  N+1  value
	    must be written as the band count in that situation.

	    If	-nodata  or -colorinterp are specified and have multiple values,
	    the band count is also inferred from that number.

     -nodata <val>[,<val>...]
	    Added in version 3.9.

	    Nodata value of the tiles of the tile index.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or as NODATA layer metadata item  for  formats  that  support  layer
	    metadata.

     -colorinterp <val>[,<val>...]
	    Added in version 3.9.

	    Color  interpretation of of the tiles of the tile index: red, green,
	    blue, alpha, gray, undefined.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or as COLOR_INTERPRETATION layer metadata item for formats that sup-
	    port layer metadata.

     -mask  Added in version 3.9.

	    Whether tiles in the tile index have a mask band.

	    Written in the XML Virtual Tile Index if -gti_filename is specified,
	    or as MASK_BAND layer metadata item for formats that  support  layer
	    metadata.

     -mo <KEY>=<VALUE>
	    Added in version 3.9.

	    Write  an  arbitrary  layer  metadata item, for formats that support
	    layer metadata.  This option may be repeated.

	    NOTE:
	       This option cannot be used together -gti_filename

     -fetch_md <gdal_md_name> <fld_name> <fld_type>
	    Added in version 3.9.

	    Fetch a metadata item from the raster tile and write it as	a  field
	    in the tile index.

	    <gdal_md_name>  should  be	the  name  of  the raster metadata item.
	    {PIXEL_SIZE} may be used as a special name	to  indicate  the  pixel
	    size.

	    <fld_name> should be the name of the field to create in the tile in-
	    dex.

	    <fld_type> should be the name of the type to create.  One of String,
	    Integer, Integer64, Real, Date, DateTime

	    This option may be repeated.

	    For example: -fetch_md TIFFTAG_DATETIME creation_date DateTime

EXAMPLES
   Example 1
     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

   Example 2
     Perform the same command as before, but now we create a GeoPackage  instead
     of a Shapefile.

	gdaltindex -of GPKG doq_index.gpkg doq/*.tif

   Example 3
     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

   Example 4
     Make a tile index from files listed in a text file, with metadata	suitable
     for use by the GDAL GTI / Virtual Raster Tile Index driver.

	gdaltindex tile_index.gti.gpkg -ot Byte -tr 60 60 -colorinterp Red,Green,Blue --optfile my_list.txt

RETURN STATUS CODE
     The  program returns status code 0 in case of success, and non-zero in case
     of error (non-blocking errors emitted as warnings are considered as a  suc-
     cessful execution).

C API
     This utility is also callable from C with GDALTileIndex().

SEE ALSO
     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.
