DESCRIPTION The ogrinfo program lists various information about an OGR-supported data source to stdout (the terminal). By executing SQL statements it is also possible to edit data. --help Show this help message and exit --help-general Gives a brief usage message for the generic GDAL commandline op- tions and exit. -if <format> Format/driver name to be attempted to open the input file(s). It is generally not necessary to specify it, but it can be used to skip automatic driver detection, when it fails to select the ap- propriate driver. This option can be repeated several times to specify several candidate drivers. Note that it does not force those drivers to open the dataset. In particular, some drivers have requirements on file extensions. Added in version 3.2. -json Display the output in json format, conforming to the ogrinfo_output.schema.json ogrinfo_output.schema.json schema. Added in version 3.7. -ro Open the data source in read-only mode. -al List all layers (used instead of having to give layer names as arguments). In the default text output, this also enables list- ing all features, which can be disabled with -so. In JSON out- put, -al is implicit, but listing of features must be explicitly enabled with -features. -rl 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). -rl cannot be used with -sql. Added in version 2.2. -so Summary Only: suppress listing of individual features and show only summary information like projection, schema, feature count and extents. In JSON output, -so is implicit and listing of features can be enabled with -features. -features Enable listing of features. This has the opposite effect of -so. This option should be used with caution if using the library function GDALVectorInfo() and/or -json, as the whole output of ogrinfo will be built in memory. Consequently, when used on a large collection of features, RAM may be exhausted. Added in version 3.7. -limit <nb_features> Added in version 3.9. Limit the number of features per layer. -q Quiet verbose reporting of various information, including coor- dinate 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. Example of -where and quoting: -where "\"Corner Point Identifier\" LIKE '%__00_00'" Note: -dialect is ignored with -where. Use -sql instead of -where if you want to use -dialect. -sql <statement>|@<filename> 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 (e.g @my_select.txt where my_select.txt is a file in the current di- rectory). Data can also be edited with SQL INSERT, UPDATE, DELETE, DROP TABLE, ALTER TABLE etc. Editing capabilities depend on the selected dialect with -dialect. -dialect <dialect> SQL dialect. In some cases can be used to use (unoptimized) OGR SQL dialect instead of the native SQL of an RDBMS by passing the OGRSQL dialect value. The SQL SQLite dialect can be selected with the SQLITE and INDIRECT_SQLITE dialect values, and this can be used with any datasource. -spat <xmin> <ymin> <xmax> <ymax> The area of interest. Only features within the rectangle will be reported. -geomfield <field> Name of the geometry field on which the spatial filter operates. -fid <fid> If provided, only the feature with this feature id will be re- ported. Operates exclusive of the spatial or attribute queries. Note: if you want to select several features based on their fea- ture 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 If set to NO, the feature dump will not display field values. Default value is YES. -fielddomain <domain_name> Added in version 3.3. Display details about a field domain. -geom=YES|NO|SUMMARY|WKT|ISO_WKT If set to NO, the feature dump will not display the geometry. If set to SUMMARY, only a summary of the geometry will be dis- played. 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 re- ported 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> Dataset open option (format specific). If a driver supports the OGR_SCHEMA open option, it can be used to partially or completely override the auto-detected schema (i.e. which fields are read, with which types, subtypes, length, precision etc.) of the dataset. The value of this option is a JSON string or a path to a JSON file that complies with the OGR_SCHEMA open option schema defin- ition -nomd Suppress metadata printing. Some datasets may contain a lot of metadata strings. -listmdd List all metadata domains available for the dataset. -mdd <domain> Report metadata for the specified domain. all can be used to re- port metadata in all domains. -nocount Suppress feature count printing. -noextent Suppress spatial extent printing. -extent3D Added in version 3.9. Request a 3D extent to be reported (the default is 2D only). Note that this operation might be slower than requesting the 2D extent, depending on format and driver capabilities. -nogeomtype Suppress layer geometry type printing. Added in version 3.1. --formats List all vector formats supported by this GDAL build (read-only and read-write) and exit. The format support is indicated as follows: • ro is read-only driver • rw is read or write (i.e. supports GDALDriver::CreateCopy()) • rw+ is read, write and update (i.e. supports GDALDriver::Create()) • A v is appended for formats supporting virtual IO (/vsimem, /vsigzip, /vsizip, etc). • A s is appended for formats supporting subdatasets. The order in which drivers are listed is the one in which they are registered, which determines the order in which they are successively probed when opening a dataset. Most of the time, this order does not matter, but in some situations, several dri- vers may recognize the same file. The -if option of some utili- ties can be specified to restrict opening the dataset with a subset of drivers (generally one). Note that it does not force those drivers to open the dataset. In particular, some drivers have requirements on file extensions. Alternatively, the GDAL_SKIP configuration option can also be used to exclude one or several drivers. -wkt_format <format> The WKT format used to display the SRS. Currently supported values for the format are: WKT1 WKT2 (latest WKT version, currently WKT2_2018) WKT2_2015 WKT2_2018 Added in version 3.0.0. <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 re- ported to the terminal. If no query parameters are provided, all features are reported. Geometries are reported in OGC WKT format. C API This utility is also callable from C with GDALVectorInfo(). Added in version 3.7.

In such cases one may use the :memory: input file which is a in-memory empty SQLite file (and the SQLite SQL dialect will be implicitly used). ogrinfo :memory: -sql "SELECT ST_Buffer(ST_GeomFromText('POINT(0 0)'), 1)" AUTHOR Frank Warmerdam <warmerdam@pobox.com>, Silke Reimer <silke@inteva- tion.de> COPYRIGHT 1998-2025 Jul 12, 2025 OGRINFO(1)
