ISPRS Test Project on Urban Classification, 3D Building Reconstruction and Semantic Labeling

In this part of our working group site you will get further information about the benchmarks we are running.

NEW 2018 - Full reference data available

As of now (summer 2018) all reference data for all benchmarks we are running is available for download - end of the benchmark challenge!

This means that we are stopping evaluating and publishing new results on our website. Instead, participants are encouraged to do an evaluation using the now available independent reference data on their own. A comparison to former results is still possible of course and appreciated. Files with the full reference data are contained in the respective folders on the download site. The naming of files should be clear enough. In order to facilitate a comparison to existing results there are still the old files with reference labels "...for_participants", i.e. a part of the full reference and in addition now the complete reference data.

In addition there is the code we have been using to evaluate the semantic labeling results. The C-code is linked to several external libraries. Please note that we cannot provide support for the software due to restricted resources.

When you request the data you will receive an ftp download link to all the data, includig all the reference data. For the formal issues (terms of use), see this doc.
