Introducing OSMLanduse.org : OpenStreetMap Landuse Landcover (LULC) WebMap is Online

Today a new global WebMap prototype “OSMLanduse.org” has been launched by GIScience Research Group Heidelberg. The map provides worldwide Landuse/Landcover information on the basis of OpenStreetMap (OSM) data. This is based on our earlier work on testing the suitability of OpenStreetMap for deriving landuse and landcover information (LULC).
LULC data is highly relevant for many research questions and practical planning activites.
Up to now there exist well known data sets generated from remote sensing imagery such as CORINE, Urban Atlas or GlobeLand30, which are available for different areas, time slots, and offer different LULC classifications.

Yet it is an interesting question if and to what degree OpenStreetMap can complement, add to, or refine these sources. Up to now this is certainly very different in different world regions and the new map helps to explore and better understand this kind of data in OSM and how it is evolving in different areas.
Therefore the aim is to evaluate the overall possibility and suitability of OpenStreetMap (OSM) data for these specific purposes, identify ways for improvement and to provide all this information globally to the interested communities in an automated way.

In order to do so, the data from OpenStreetMap was initially categorized similar to the classification level 2 of the CORINE Landcover classes. This category mapping and further pre-processing of OSM data will be further refined in ongoing work.
A first basic WebMapping application has been set up with the use of free and open-source software, including PostgreSQL/PostGIS, Geoserver and MapProxy. At the moment the website provides basic WebGIS elements, such as legend, search function and feature info. Higher zoomlevels (>7) are updated on a minutely basis. In the near future we want to implement other useful features and explore ways to measure the quality of the data. Right now GIScience HD isworking on realizing a function, which provides statistical information about the landuse/landcover in a certain area (bbox), defined by the user.
In particular also the mapping between common land use classifications such as CORINE, Urban Atlas etc. and the OpenStreetMap categorization of objects is refined and the preprocessing for different scales improved.
So stay tuned for further updates!
