NAME
ogrtindex - Creates a tileindex.
SYNOPSIS
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
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 their
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 in-
dex.
-f <output_format>
Select an output format name. The default is to create a shape-
file.
-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>
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.
New in version 2.2.0.
-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 >= 7.2.
New in version 2.2.0.
-src_srs_format <format>
The format in which the SRS of each tile must be written.
Available formats are: AUTO, WKT, EPSG, PROJ.
New in version 2.2.0.
-accept_different_schemas
By default ogrtindex checks that all layers inserted into the
index have the same attribute schemas. If you specify this op-
tion, 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 direc-
tory:
