Interlis QGIS plugin

QGIS Plugin for importing and exporting Interlis data.

ogrtools

ogrtools is a collection of libraries and tools built with the Python API of OGR.

pyogr library

pyogr gives you OGR commands like ogr2ogr or ogrinfo as Python library, i.e. without calling an external executable file. Most of the code is already included in the OGR source distribution as samples for using the Python API.

• ogr2ogr.py: ogr2ogr call with stdout/stderr redirection
• ogrinfo.py: ogrinfo call
• ogrvrt.py: generate a VRT from a datasource
• ogrds.py: Call OGR SQL commands on a datasource

interlis library

Extensions for the OGR Interlis driver.

• Automatic detection of used models in transfer files
• Extracting enums from IlisMeta model
• Loading and converting of Interlis models from model repositories

ogr command line tool

The ogr command line tool exposes ogrtools functionality for using in a command shell.

ogr --help
usage: ogr [-h]
           {version,formats,info,sql,vrt,genconfig,write-enums,transform} ...

Query and transform OGR compatible vector data

optional arguments:
  -h, --help            show this help message and exit

commands:
  valid commands

  {version,formats,info,sql,vrt,genconfig,write-enums,transform}
    version             Show version information
    formats             List available data formats
    info                Information about data
    sql                 Execute SQL Query
    vrt                 Create VRT from data source
    genconfig           Generate OGR configuration from data source
    write-enums         Write tables with enumeration values
    transform           Transform data source based on OGR configuration

ogr version

Show version information

usage: ogr version [-h]

ogr formats

List available data formats

ogr vrt

Create VRT from data source

usage: ogr vrt [-h] source [layers [layers ...]]

Example:

ogr vrt tests/data/osm/railway.shp

<OGRVRTDataSource>
  <OGRVRTLayer name="railway">
    <SrcDataSource relativeToVRT="0" shared="1">tests/data/osm/railway.shp</SrcDataSource>
    <SrcLayer>railway</SrcLayer>
    <GeometryType>wkbLineString</GeometryType>
    <LayerSRS>GEOGCS[&quot;GCS_WGS_1984&quot;,DATUM[&quot;WGS_1984&quot;,SPHEROID[&quot;WGS_84&quot;,6378137,298.257223563]],PRIMEM[&quot;Greenwich&quot;,0],UNIT[&quot;Degree&quot;,0.017453292519943295]]</LayerSRS>

Development

git clone https://github.com/sourcepole/qgis-interlis-plugin.git

Running tests:

apt-get install python3-nose

python3 -m "nose"
The tests were made for GDAL version 2.2.2

For running ogr commands from source tree:

alias ogr="PYTHONPATH=$(pwd) $(pwd)/ogr_cli/ogr.py"
