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 AUTHORS

ogrinfo(1) General Commands Manual ogrinfo(1) NAME
ogrinfo - ogrinfo lists information about an OGR supported data source SYNOPSIS
ogrinfo [--help-general] [-ro] [-q] [-where restricted_where] [-spat xmin ymin xmax ymax] [-fid fid] [-sql statement] [-dialect dialect] [-al] [-so] [-fields={YES/NO}] [-geom={YES/NO/SUMMARY}][--formats] datasource_name [layer [layer ...]].fi DESCRIPTION
The ogrinfo program lists various information about an OGR supported data source to stdout (the terminal). -ro: Open the data source in read-only mode. -al: List all features of all layers (used instead of having to give layer names as arguments). -so: Summary Only: supress listing of features, show only the summary information like projection, schema, feature count and extents. -q: Quiet verbose reporting of various information, including coordinate system, layer schema, extents, and feature count. -where restricted_where: An attribute query in a restricted form of the queries used in the SQL WHERE statement. Only features matching the attribute query will be reported. -sql statement: Execute the indicated SQL statement and return the result. -dialect dialect: SQL dialect. In some cases can be used to use (unoptimized) OGR SQL instead of the native SQL of an RDBMS by passing OGRSQL. -spat xmin ymin xmax ymax: The area of interest. Only features within the rectangle will be reported. -fid fid: If provided, only the feature with this feature id will be reported. Operates exclusive of the spatial or attribute queries. Note: if you want to select several features based on their feature id, you can also use the fact the 'fid' is a special field recognized by OGR SQL. So, '-where 'fid in (1,3,5)'' would select features 1, 3 and 5. -fields={YES/NO}: (starting with GDAL 1.6.0) If set to NO, the feature dump will not display field values. Default value is YES. -geom={YES/NO/SUMMARY}: (starting with GDAL 1.6.0) If set to NO, the feature dump will not display the geometry. If set to SUMMARY, only a summary of the geometry will be displayed. If set to YES, the geometry will be reported in full OGC WKT format. Default value is YES. --formats: List the format drivers that are enabled. datasource_name: The data source to open. May be a filename, directory or other virtual name. See the OGR Vector Formats list for supported datasources. layer: One or more layer names may be reported. If no layer names are passed then ogrinfo will report a list of available layers (and their layerwide geometry type). If layer name(s) are given then their extents, coordinate system, feature count, geometry type, schema and all features matching query parameters will be reported to the terminal. If no query parameters are provided, all features are reported. Geometries are reported in OGC WKT format. EXAMPLE
Example reporting all layers in an NTF file: % ogrinfo wrk/SHETLAND_ISLANDS.NTF INFO: Open of `wrk/SHETLAND_ISLANDS.NTF' using driver `UK .NTF' successful. 1: BL2000_LINK (Line String) 2: BL2000_POLY (None) 3: BL2000_COLLECTIONS (None) 4: FEATURE_CLASSES (None) Example using an attribute query is used to restrict the output of the features in a layer: % ogrinfo -ro -where 'GLOBAL_LINK_ID=185878' wrk/SHETLAND_ISLANDS.NTF BL2000_LINK INFO: Open of `wrk/SHETLAND_ISLANDS.NTF' using driver `UK .NTF' successful.
