Xerces

OGR has support for INTERLIS reading.
INTERLIS is a standard which has been especially composed in order to fulfill the requirements of modeling and the integration of geodata into contemporary and future geographic information systems. With the usage of unified, documented geodata and the flexible exchange possibilities the following advantage may occur:

  • the standardized documentation

  • the compatible data exchange

  • the comprehensive integration of geodata e.g. from different data owners.

  • the quality proofing

  • the long term data storage

  • the contract-proof security and the availability of the software

OGR supports INTERLIS 1 and INTERLIS 2 (2.2 and newer) with the following limitations:

  • Curves in Interlis 1 area polygons are converted to line segments

  • Interlis 1 Surface geometries with non-numeric IDENT field are not included in the attribute layer

  • Embedded INTERLIS 2 structures and line attributes are not supported

  • Incremental transfer is not supported

  • Transfer id (TID) is used as feature id

Driver capabilities

Supports Georeferencing

This driver supports georeferencing

Supports VirtualIO

This driver supports virtual I/O operations (/vsimem/, etc.)

Dataset open options

Open options can be specified in command-line tools using the syntax -oo <NAME>=<VALUE> or by providing the appropriate arguments to GDALOpenEx() (C) or gdal.OpenEx (Python). The following open options are available:

  • MODEL=value: Path to IlisMeta model file.

Model support

Data is read from transfer files which have different formats in INTERLIS 1 (.itf) and INTERLIS 2 (.xtf). Models are passed in IlisMeta format with the open option MODEL or by using "a_filename.xtf,models.imd" as a connection string.

IlisMeta files can be be generated with the ili2c compiler. Command line example:

java -jar ili2c.jar --ilidirs '%ILI_DIR;http://models.interlis.ch/;%JAR_DIR' -oIMD --out models.imd model1.ili [model2.ili ...]

or for newer models:

java -jar ili2c.jar --ilidirs '%ILI_DIR;http://models.interlis.ch/;%JAR_DIR' -oIMD16 --out models.imd model1.ili [model2.ili ...]

Some possible transformations using ogr2ogr.

  • Interlis 1 -> Shape:

    gdal vector convert --oo MODEL=Beispiel.imd -f "ESRI Shapefile" ili-bsp.itf shpdir

  • Interlis 2 -> GeoPackage:

    gdal vector convert --oo MODEL=KGKCGC_FPDS2_V1_1.imd fpds2_v1_1.xtf fpds2_v1_1.gpkg

    or without model:

    gdal vector convert -f "ESRI Shapefile" RoadsExdm2ien.xml shpdir

    Example with curves and multiple geometries:

    gdal vector sql --oo MODEL=OeREBKRM09vs.imd --config OGR_STROKE_CURVE=TRUE --sql 'SELECT Rechtsstatus,publiziertAb,MetadatenGeobasisdaten,Eigentumsbeschraenkung,ZustaendigeStelle,Flaeche FROM "OeREBKRM09trsfr.Transferstruktur.Geometrie"' -f "ESRI Shapefile" ch.bazl.sicherheitszonenplan.oereb_20131118.xtf shpdir

  • Importing multiple Interlis 1 files into PostGIS:

    gdal vector convert --oo MODEL=av.imd --overwrite-layer av_fixpunkte_ohne_LFPNachfuehrung.itf PG:dbname=warmerda
gdal vector convert --oo MODEL=av.imd --append av_fixpunkte_mit_LFPNachfuehrung.itf PG:dbname=warmerda

Arc interpolation

Converting INTERLIS arc geometries to line segments can be forced by setting the configuration variable OGR_STROKE_CURVE to TRUE.
The approximation of arcs as linestrings is done by splitting the arcs into subarcs of no more than a threshold angle. This angle is the OGR_ARC_STEPSIZE. This defaults to one degree, but may be overridden by setting the configuration variable OGR_ARC_STEPSIZE.
