NAME

gdaltindex - 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 builds a shapefile 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:
(GDAL >= 1.11)

The OGR format of the output tile index file. Default is 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. Using this option generates files that are not compatible with MapServer < 6.4.
Default creates simple rectangular polygons in the same coordinate reference system as the
input rasters.

-src_srs_name field_name:
(GDAL >= 1.11)

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 >= 6.4.

-src_srs_format type:
(GDAL >= 1.11)

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 shapefile will be created if
it doesn't already exist, otherwise it will append to the existing file.

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

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
