NAME

6       ogrtindex - ogrtindex creates a tileindex
7

SYNOPSIS

9       ogrtindex [-lnum n]... [-lname name]... [-f output_format]
10                        output_dataset src_dataset...

DESCRIPTION

13       The ogrtindex program can be used to create a tileindex - a file
14       containing a list of the identities of a bunch of other files along
15       with there spatial extents. This is primarily intended to be used with
16       the UMN MapServer for tiled access to layers using the OGR connection
17       type.
18
19       -lnum n:
20           Add layer number 'n' from each source file in the tile index.
21
22       -lname name:
23           Add the layer named 'name' from each source file in the tile index.
24
25       -f output_format:
26           Select an output format name. The default is to create a shapefile.
27
28       -tileindex field_name:
29           The name to use for the dataset name. Defaults to LOCATION.
30
31       If no -lnum or -lname arguments are given it is assumed that all layers
32       in source datasets should be added to the tile index as independent
33       records.
34
35       If the tile index already exists it will be appended to, otherwise it
36       will be created.
37
38       It is a flaw of the current ogrtindex program that no attempt is made
39       to copy the coordinate system definition from the source datasets to
40       the tile index (as is expected by MapServer when PROJECTION AUTO is in
41       use).

EXAMPLE

44       This example would create a shapefile (tindex.shp) containing a tile
45       index of the BL2000_LINK layers in all the NTF files in the wrk
46       directory:
47
48       % ogrtindex tindex.shp wrk/*.NTF
