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).
- -rl:
- (Available in GDAL 2.2) Enable random layer reading mode, i.e. iterate over features in the order they are found in the dataset, and not layer per layer. This can be significantly faster for some formats (for example OSM, GMLAS).
- -so:
- Summary Only: suppress 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. Starting with GDAL 2.1, the \filename syntax can be used to indicate that the content is in the pointed filename.
- -sql statement:
- Execute the indicated SQL statement and return the result. Starting with GDAL 2.1, the @filename syntax can be used to indicate that the content is in the pointed filename.
- -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. Starting with GDAL 1.10, the 'SQLITE' dialect can also be used with any datasource.
- -spat xmin ymin xmax ymax:
- The area of interest. Only features within the rectangle will be reported.
- -geomfield field:
- (OGR >= 1.11) Name of the geometry field on which the spatial filter operates on.
- -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/WKT/ISO_WKT}:
- (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 or ISO_WKT, the geometry will be reported in full OGC WKT format. If set to WKT the geometry will be reported in legacy WKT. Default value is YES. (WKT and ISO_WKT are available starting with GDAL 2.1, which also changes the default to ISO_WKT)
- -oo NAME=VALUE:
- (starting with GDAL 2.0) Dataset open option (format specific)
- -nomd
- (starting with GDAL 2.0) Suppress metadata printing. Some datasets may contain a lot of metadata strings.
- -listmdd
- (starting with GDAL 2.0) List all metadata domains available for the dataset.
- -mdd domain
- (starting with GDAL 2.0) Report metadata for the specified domain. 'all' can be used to report metadata in all domains
- -nocount
- (starting with GDAL 2.0) Suppress feature count printing.
- -noextent
- (starting with GDAL 2.0) Suppress spatial extent printing.
- --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 layer wide 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.
Layer name: BL2000_LINK
Geometry: Line String
Feature Count: 1
