ogrtindex

Creates a tileindex.

SYNOPSIS

Usage:

ogrtindex [-lnum n]... [-lname name]... [-f output_format]
          [-write_absolute_path] [-skip_different_projection]
          [-t_srs target_srs]
          [-src_srs_name field_name] [-src_srs_format [AUTO|WKT|EPSG|PROJ]
          [-accept_different_schemas]
                 output_dataset src_dataset...

DESCRIPTION

The ogrtindex program can be used to create a tileindex - a file containing a list of the identities of a bunch of other files along with there spatial extents. This is primarily intended to be used with MapServer for tiled access to layers using the OGR connection type.

-lnum n:

Add layer number 'n' from each source file in the tile index.

-lname name:

Add the layer named 'name' from each source file in the tile index.

-f output_format:

Select an output format name. The default is to create a shapefile.

-tileindex field_name:

The name to use for the dataset name. Defaults to LOCATION.

-write_absolute_path:

Filenames are written with absolute paths

-skip_different_projection:

Only layers with same projection ref as layers already inserted in the tileindex will be inserted.

-t_srs target_srs:

(GDAL >= 2.2)

Extent of input files will be transformed to the desired target coordinate reference system. Using this option generates files that are not compatible with MapServer < 7.2. Default creates simple rectangular polygons in the same coordinate reference system as the input vector layers.

-src_srs_name field_name:

(GDAL >= 2.2)

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 >= 7.2.

-src_srs_format type:

(GDAL >= 2.2)

The format in which the SRS of each tile must be written. Types can be AUTO, WKT, EPSG, PROJ.

-accept_different_schemas:

By default ogrtindex checks that all layers inserted into the index have the same attribute schemas. If you specify this option, this test will be disabled. Be aware that resulting index may be incompatible with MapServer!

If no -lnum or -lname arguments are given it is assumed that all layers in source datasets should be added to the tile index as independent records.

If the tile index already exists it will be appended to, otherwise it will be created.

EXAMPLE

This example would create a shapefile (tindex.shp) containing a tile index of the BL2000_LINK layers in all the NTF files in the wrk directory:

% ogrtindex tindex.shp wrk/*.NTF
