1.. _vector.sxf: 2 3Storage and eXchange Format - SXF 4================================= 5 6.. shortname:: SXF 7 8.. built_in_by_default:: 9 10This driver reads SXF files, open format often associated with Russian 11GIS Software Panorama. 12 13The driver is read only, but supports deletion of data source. The 14driver supports SXF binary files version 3.0 and higher. 15 16The SXF layer support the following capabilities: 17 18- Strings as UTF8 19- Random Read 20- Fast Feature Count 21- Fast Get Extent 22- Fast Set Next By Index 23 24The driver uses classifiers (RSC files) to map feature from SXF to 25layers. Features that do not belong to any layer are put to the layer 26named "Not_Classified". The layers with zero features are not present in 27data source. 28 29To be used automatically, the RSC file should have the same name as SXF 30file. User can provide RSC file path using config option 31**SXF_RSC_FILENAME**. This config option overrides the use of same name 32RSC. 33 34The RSC file usually stores long and short layer name. The long name is 35usually in Russian, and short in English. The **SXF_LAYER_FULLNAME** 36config option allows choosing which layer names to use. If 37SXF_LAYER_FULLNAME is TRUE - the driver uses long names, if FALSE - 38short. 39 40The attributes are read from SXF file. Maximum number of fields is 41created for the same layer features with different number of attributes. 42If attribute has a code mapped to RSC file, driver adds only the code 43(don't get real value from RSC, as the value type may differ from field 44type). 45 46If config option **SXF_SET_VERTCS** set to ON, the layers spatial 47reference will include vertical coordinate system description if exist. 48 49Since GDAL 3.1 config options can be passed as driver open options. 50 51Driver capabilities 52------------------- 53 54.. supports_georeferencing:: 55 56.. supports_virtualio:: 57 58See Also 59-------- 60 61- `Panorama web page <http://gisinfo.ru>`__ 62- `SXF binary format description v.4 (rus) - 63 pdf <http://gistoolkit.ru/download/doc/sxf4bin.pdf>`__ 64- `SXF binary format description v.4 (rus) - 65 doc <http://gistoolkit.ru/download/classifiers/formatsxf.zip>`__ 66- `SXF format description v.3 67 (rus) <http://loi.sscc.ru/gis/formats/Format-geo/sxf/sxf3-231.txt>`__ 68- `RSC format description 69 (rus) <http://gistoolkit.ru/download/classifiers/formatrsc.zip>`__ 70- `Test spatial data in SXF format 71 (rus) <http://www.gisinfo.ru/price/price_map.htm>`__ 72- `Some RSC files 73 (rus) <http://www.gisinfo.ru/classifiers/classifiers.htm>`__ 74
