20 The ogrinfo program lists various information about an OGR supported
21 data source to stdout (the terminal).
22 -ro:
24 Open the data source in read-only mode.
25 -al:
27 List all features of all layers (used instead of having to give
28 layer names as arguments).
29 -so:
31 Summary Only: supress listing of features, show only the summary
32 information like projection, schema, feature count and extents.
33 -q:
35 Quiet verbose reporting of various information, including
36 coordinate system, layer schema, extents, and feature count.
37 -where restricted_where:
39 An attribute query in a restricted form of the queries used in the
40 SQL WHERE statement. Only features matching the attribute query
41 will be reported.
42 -sql statement:
44 Execute the indicated SQL statement and return the result.
45 -spat xmin ymin xmax ymax:
47 The area of interest. Only features within the rectangle will be
48 reported.
49 -fid fid:
51 If provided, only the feature with this feature id will be
52 reported. Operates exclusive of the spatial or attribute queries.
53 Note: if you want to select several features based on their feature
54 id, you can also use the fact the 'fid' is a special field
55 recognized by OGR SQL. So, '-where 'fid in (1,3,5)'' would select
56 features 1, 3 and 5.
57 -fields={YES/NO}:
59 (starting with GDAL 1.6.0) If set to NO, the feature dump will not
60 display field values. Default value is YES.
61 -geom={YES/NO/SUMMARY}:
63 (starting with GDAL 1.6.0) If set to NO, the feature dump will not
64 display the geometry. If set to SUMMARY, only a summary of the
65 geometry will be displayed. If set to YES, the geometry will be
66 reported in full OGC WKT format. Default value is YES.
67 --formats:
69 List the format drivers that are enabled.
70 datasource_name:
72 The data source to open. May be a filename, directory or other
73 virtual name. See the OGR Vector Formats list for supported
74 datasources.
75 layer:
77 One or more layer names may be reported.
78 If no layer names are passed then ogrinfo will report a list of
80 available layers (and their layerwide geometry type). If layer name(s)
81 are given then their extents, coordinate system, feature count,
82 geometry type, schema and all features matching query parameters will
83 be reported to the terminal. If no query parameters are provided, all
84 features are reported.
85 Geometries are reported in OGC WKT format.
87
89 Example reporting all layers in an NTF file:
90 % ogrinfo wrk/SHETLAND_ISLANDS.NTF
92 INFO: Open of `wrk/SHETLAND_ISLANDS.NTF'
93 using driver `UK .NTF' successful.
94 1: BL2000_LINK (Line String)
95 2: BL2000_POLY (None)
96 3: BL2000_COLLECTIONS (None)
97 4: FEATURE_CLASSES (None)
98 Example using an attribute query is used to restrict the output of the
101 features in a layer:
102 % ogrinfo -ro -where 'GLOBAL_LINK_ID=185878' wrk/SHETLAND_ISLANDS.NTF BL2000_LINK
104 INFO: Open of `wrk/SHETLAND_ISLANDS.NTF'
105 using driver `UK .NTF' successful.
