<html> <head> <title>INTERLIS</title> </head> <body bgcolor="#ffffff"> <h1>INTERLIS</h1> OGR has support for INTERLIS reading and writing.<br> <a href="http://www.interlis.ch/">INTERLIS</a> is a standard which has been especially composed in order to fulfil the requirements of modelling and the integration of geodata into contemporary and future geographic information systems. The current version is INTERLIS version 2. INTERLIS version 1 remains a Swiss standard. With the usage of unified, documented geodata and the flexible exchange possibilities the following advantage may occur: <ul> <li>the standardized documentation <li>the compatible data exchange <li>the comprehensive integration of geodata e.g. from different data owners. <li>the quality proofing <li>the long term data storage <li>the contract-proof security and the availability of the software </ul> <h2>Model</h2> Data is read and written into transfer files which have different formats in INTERLIS 1 (.itf) and INTERLIS 2 (.xml). For using the INTERLIS model (.ili) a Java interpreter is needed at runtime, and the <a href="http://home.gdal.org/dl/ili2c.jar">ili2c.jar</a> file must be in the Java path. The model file can be added to the transfer file seperated by a comma.<p> Some possible transformations using <a href="http://www.gdal.org/ogr/ogr2ogr.html">ogr2ogr</a>.<p> <ul> <li> Interlis 1 -> Shape: <pre> ogr2ogr -f "ESRI Shapefile" shpdir ili-bsp.itf,ili-bsp.ili </pre> </li> <li> Interlis 2 -> Shape: <pre> ogr2ogr -f "ESRI Shapefile" shpdir RoadsExdm2ien.xml,RoadsExdm2ben.ili,RoadsExdm2ien.ili </pre> or without model: <pre> ogr2ogr -f "ESRI Shapefile" shpdir RoadsExdm2ien.xml </pre> </li> <li> Shape -> Interlis 1: <pre> ogr2ogr -f "Interlis 1" ili-bsp.itf Bodenbedeckung__BoFlaechen_Form.shp </pre> </li> <li> Shape -> Interlis 2: <pre> ogr2ogr -f "Interlis 2" LandCover.xml,RoadsExdm2ben.ili RoadsExdm2ben_10.Roads.LandCover.shp </pre> </li> <li> Incremental import from Interlis 1 into PostGIS: <pre> ogr2ogr -f PostgreSQL PG:dbname=warmerda av_fixpunkte_ohne_LFPNachfuehrung.itf,av.ili -lco OVERWRITE=yes ogr2ogr -f PostgreSQL PG:dbname=warmerda av_fixpunkte_mit_LFPNachfuehrung.itf,av.ili -append </pre> </li> </ul> <p> <h3>Arc interpolation</h3> INTERLIS arc geometries are converted to polygons.<br></br> The interpolation angle can be changed with the environment variable ARC_DEGREES (Default: 1 degree).<br></br> <h2>Other Notes</h2> <ul> <li>More Information: <a href="http://gis.hsr.ch/wiki/OGR">http://gis.hsr.ch/wiki/OGR</a> (german)</li> <li> Development of the OGR INTERLIS driver was supported by <a href="http://www.kogis.ch/">Swiss Federal Administration</a>, <a href="http://www.so.ch/de/pub/departemente/bjd/gis.htm">Canton Solothurn</a> and <a href="http://www.geoinformation.tg.ch/">Canton Thurgovia</a>.</li> </ul> </body> </html>
