SHP, TAB) can have dual behaviors, that is if they’re OGR reads all the files in the directory as a single data source with roads.shp or roads.tab) and whenĪccessing a directory-based data source you specify the directory name and When accessing a file-based data source you specify theįilename of one of the files in the set (e.g. Let’s call the former «File-based data sources» and the later «Directory-basedĭata sources». tab/.map/.dat/.ind/.id for MapInfo TAB files) or a whole directory of files In OGR, a data source can be either a set of files that share a commonīasename (e.g.shp/.shx/.dbf for ArcView Shapefiles, or Vector Data Access Guide is an excellent resource for this). The syntax for this differs depending on the type of data being used (the Three parameters (CONNECTIONTYPE OGR, CONNECTION and DATA). The LAYER’s DATA parameter is expanded to The only change that is needed to integrate OGR support with a MapServerĪpplication is with the.

Starting with MapServer 7.0, 2.5D geometries, when handled by OGR drivers andĭata sources, can be taken into account by MapServer if it is built with Then see the README.WIN32 file in the MapServer source.

Linux users might want to try FGS, a Linuxįor Windows users, it is recommended to look for a pre-compiled binary on the Installed it should be sufficient to add -DWITH_OGR=ON to the cmake lineīefore (re)building MapServer.
Obtaining and Compiling MapServer with OGR Support ¶įollow the instructions on the GDAL page to compile/install OGR/GDAL. The main developer of the OGR library is currently Even Rouault (with originalĭevelopment by Frank Warmerdam) and the integration of OGR within MapServer
The #gdal IRC channel on might also be of help. The old GDAL Wiki has lots of good information for users and developers. Search the list archives before sending new questions. The GDAL mailing list can be used for OGR related questions. The legacy pages on the OGR Simple Features Project can be found on the

How to Get More Information on the OGR Project ¶Īs OGR is now merged with GDAL as of GDAL 2.0, the main GDAL site Will give performance comparable to native shapefile access in MapServer. On the other hand, someīinary formats such as MapInfo TAB are better suited for random access and Give very poor performance for a web application. That’s the case of MapInfo MIF/MID files which is a TEXT format and will Some of the above formats are not well suited for random access by nature, Mid/Mif and TAB data do not need to be converted to ESRI shapefiles when using Types of vector data files in their native formats. The OGR Simple Features Library allows MapServer users to display several References point to GDAL (such as the mailing list). OGR is actually part of the GDAL library, so you will notice that some Tools) providing read (and sometimes write) access to a variety of vector fileįormats including ESRI Shapefiles, and MapInfo mid/mif and TAB formats.
