- 3. SUPPORTING PROJECTS SDI4Apps finished this year and it was an EU-funded project managed by the University of West Bohemia from the Czech Republic. The project is being implemented with the concerted effort of 18 organizations across Europe. SDI4Apps seeks to build a cloud-based framework with open API for data integration focusing on the development of six pilot applications. The project draws along the lines of INSPIRE, Copernicus and GEOSS and aspires to build a WIN-WIN strategy for building a successful business for hundreds of SMEs on the basis of European spatial data infrastructures.

- 4. INPUT DATA • OLU database for the Czech Republic • SPOI database for the Czech Republic INSPIRE Conference, Kehl, 5th Sept 2017
- 5. USED SOFTWARE/TOOLS • Mapserver for data visualization in a heatmap technique INSPIRE Conference, Kehl, 5th Sept 2017
- 6. PROJECT IDEA AND RESULTS • The aim was to do some precomputation, i.e. to precompute ,in which land use type, each SPOI is lying, and then to visualize the density of SPOI filtered by different land use types. • Initially it was thought that the WebGL library is perfect tool for this task as it would allow interactive filtering of land use categories. Unfortunately there wasn’t time for this. So the map was created with the help of Mapserver and is available now at: https://goo.gl/pabypt . Two categories of land use were selected for which heatmaps were constructed: residential areas and areas used in primary sector of economy (agriculture, forestry, mines).

- 8. PROJECT IDEA AND RESULTS • The main lesson learnt was that such combination of these two datasets doesn’t bring anything unexpected and doesn’t give much insights. What would be interesting however is to try to use SPOI to define the land use type of certain OLU objects, which for now have land use attribute from not so precise/reliable sources.

- 10. REUSE • The idea to use SPOI in defining land use type of objects from OLU dataset will be definitely reused. It is very relevant for instance in Flanders region of Belgium, where cadastral parcels don’t have land use attribute and it needs to be derived from somewhere. For now it was derived from Urban Atlas and Corine datasets. But it was a very rough guess. I think using SPOI for this purpose will give more reliable results.
