DESCRIPTION

17       The ogrtindex program can be used to create a tileindex - a file
18       containing a list of the identities of a bunch of other files along
19       with there spatial extents. This is primarily intended to be used with
20       MapServer for tiled access to layers using the OGR connection type.
21
22       -lnum n:
23           Add layer number 'n' from each source file in the tile index.
24
25       -lname name:
26           Add the layer named 'name' from each source file in the tile index.
27
28       -f output_format:
29           Select an output format name. The default is to create a shapefile.
30
31       -tileindex field_name:
32           The name to use for the dataset name. Defaults to LOCATION.
33
34       -write_absolute_path:
35           Filenames are written with absolute paths
36
37       -skip_different_projection:
38           Only layers with same projection ref as layers already inserted in
39           the tileindex will be inserted.
40
41       -t_srs target_srs:
42           (GDAL >= 2.2)
43
44       Extent of input files will be transformed to the desired target
45       coordinate reference system. Using this option generates files that are
46       not compatible with MapServer < 7.2. Default creates simple rectangular
47       polygons in the same coordinate reference system as the input vector
48       layers.
49
50       -src_srs_name field_name:
51           (GDAL >= 2.2)
52
53       The name of the field to store the SRS of each tile. This field name
54       can be used as the value of the TILESRS keyword in MapServer >= 7.2.
55
56       -src_srs_format type:
57           (GDAL >= 2.2)
58
59       The format in which the SRS of each tile must be written. Types can be
60       AUTO, WKT, EPSG, PROJ.
61
62       -accept_different_schemas:
63           By default ogrtindex checks that all layers inserted into the index
64           have the same attribute schemas. If you specify this option, this
65           test will be disabled. Be aware that resulting index may be
66           incompatible with MapServer!
67
68       If no -lnum or -lname arguments are given it is assumed that all layers
69       in source datasets should be added to the tile index as independent
70       records.
71
72       If the tile index already exists it will be appended to, otherwise it
73       will be created.

EXAMPLE

76       This example would create a shapefile (tindex.shp) containing a tile
77       index of the BL2000_LINK layers in all the NTF files in the wrk
78       directory:
79
80       % ogrtindex tindex.shp wrk/*.NTF
