This is the command ogrtindex that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
ogrtindex - ogrtindex creates a tileindex
SYNOPSIS
ogrtindex [-lnum n]... [-lname name]... [-f output_format]
[-write_absolute_path] [-skip_different_projection]
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.
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.
It is a flaw of the current ogrtindex program that no attempt is made to copy the
coordinate system definition from the source datasets to the tile index (as is expected by
MapServer when PROJECTION AUTO is in use).
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
