OSGeo – GDAL/OGR import BGT/IMGeo (continuation)

GDAL is a C++ translator library for more than 200 raster and vector geospatial data formats. It offers an API for a variety of languages such as C, C++, Python, Perl, C# and Java.

vdPConsulting has investigated whether and how this GDAL/OGR functionality can be implemented in a C# plugin in AutoCAD.

As Proof of Concept II, the download of the BGT and BRK/DKK from the PDOK website has been implemented. Based on a project polygon, a location filter is created and sent to PDOK as a spatial query. The result is downloaded (as a ZIP-file) and extracted into the project folder and then imported into AutoCAD.

OSGeo – GDAL/OGR import BGT/IMGeo

GDAL is a C++ translator library for more than 200 raster and vector geospatial data formats. It offers an API for a variety of languages such as C, C++, Python, Perl, C# and Java.

vdPConsulting has investigated whether and how this GDAL/OGR functionality can be implemented in a C# plugin in AutoCAD.

The import of the BGT/IMGeo is implemented as a Proof of Concept. Processed to NLCS-layers based on the features. At a later stage this can always be further broken down based on multiple properties. By keeping the fill and outline separated from each other, a simple Layer-command can be used to turn the fill off and switch to a line map. The software creates a set of Layer Filters for this purpose.

OSGeo – GDAL/OGR in vdPClassify and vdPCADdesign

GDAL is a C++ translator library for more than 200 raster and vector geospatial data formats. It offers an API for a variety of languages such as C, C++, Python, Perl, C# and Java.

vdPConsulting has investigated whether and how this GDAL/OGR functionality can be implemented in a C# plugin in AutoCAD.

In vdPCADdesign, it is now possible to export CADdesign-objects to GML, GeoJSON, GeoPackage and ESRI Shape files. For reading from the same files, CADdesign-objects are expected to write them as objects in the drawing.

Also in vdPClassify it is now possible to export Classify-objects to GML, GeoJSON, GeoPackage and ESRI Shape files. For reading in from the same files, generic functions have been implemented in the vdPClassify-toolkit that read in the points, lines and polygons and create them as generic AutoCAD Points, Polylines and Closed Polylines in the drawing.

OSGeo – GDAL/OGR

GDAL is a C++ translator library for more than 200 raster and vector geospatial data formats. It offers an API for a variety of languages such as C, C++, Python, Perl, C# and Java.

In the Visual Studio development environment it is possible to download NuGet packages. These are open source development libraries you can simply add to your .NET project.

A number of NuGet packages are available for GDAL. In addition to the complete GDAL environment, so-called .NET wrappers are installed with which C# functions in the underlying GDAL C++ DLLs can be called.

vdPConsulting is currently investigating the possibilities to implement GDAL/OGR functionality in a C# plugin in AutoCAD to export data to and import from GML, GeoJSON, GeoPackage and ESRI Shape files.

The projects listed here offer freely available tools and technologies under an open source license. 

A small selection of the large number of projects:

MapGuide Open Source & FDO

MapGuide Open Source is a web-based platform that enables users to develop and deploy web mapping applications and geospatial web services. FDO Data Access Technology is an API for manipulating, defining and analysing geospatial information regardless of where it is stored.

MapGuide & FDO were Autodesk commercial products submitted to OSGeo in March 2006.
