GI2010 symposium-koskova+charvat (flood)

  1. 1. G I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum THE EU-CIP-PROJECT “BRISEIDE” ANALYTICAL CAPABILITIES ON REGIONAL GEOPORTAL IRENA KOŠKOVÁ Regional Government, Liberec Region & KAREL CHARVÁT CCSS, Prague
  2. 2. MAIN OBJECTIVEG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum 1. The main objective is to present extended functionality of existing regional Flood Portal - online available spatial analysis possibilities 2. For the communication between the mapping application (client) and GRASS GIS, OGC Web Processing Service protocol was used (implemented by PyWPS on the server-side). 3. The functionality was made by using GRASS GIS modules: r.lake … for flooding r.drain … for runoff r.water.outlet … for catchement r.los … for visibility

  4. 4. OGC Web Processing ServiceG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum OGC’s Web Processing Service is defining the way, geoprocessing operations should be offered over networks using Web Services. Can be configured to offer any sort of GIS functionality to clients across a network. Data can be stored on the server, sent with the request or stored on remote servers (WCS, WFS, . . . ) The GIS functionality is referred as process Scope: To move the geospatial calculations from client to server
  5. 5. PyWPSG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum Implementation of OGC Web Processing Service 0.4.0 Only interface between Internet and used programs GRASS GIS, R, GDAL/OGR, PROJ.4, . . . Free Software, GNU/GPL. Supported by Help Service - Remote Sensing PyWPS has been developed with support of DBU (Deutsche Bundestifftung Umwelt). http://pywps.wald.intevation.org
  6. 6. PyWPS demo on Flood Portal of Liberec RegionG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum 1. Spatial analysis - CATCHMENT / BASIN Calculation of the catchment area for a given point. To achieve meaningful results it is necessary to enter a point on Thalweg. The result is the area from which water flows to the specified point The calculated data  can be downloaded  in GeoTIFF format
  7. 7. PyWPS demo on Flood Portal of Liberec RegionG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum 2. Spatial analysis - RUNOFF Calculate fluid drain path from the specified location. The calculation can be used as a quick graphical representation of risk in case of leakage flows hazardous liquids. The calculated data  can be downloaded  like GML
  8. 8. PyWPS demo on Flood Portal of Liberec RegionG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum 3. Spatial analysis - FLOODING Calculate the area submerged for a given height of water at a specified point. The calculated data  can be downloaded  in GeoTIFF format
  9. 9. PyWPS demo on Flood Portal of Liberec RegionG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum 4. Spatial analysis - VISIBILITY Calculation of the visibility analysis. Result of calculating is the area, visible from the place the observer stands The calculated data  can be downloaded  in GeoTIFF format
  10. 10. THANK YOU FOR YOUR ATTENTIONG I 2 0 1 0 D r e s d e n – 10. Sächsisches GIS-Forum Ing. Irena Košková Regional Authority of Liberec Region, Czech Republic irena.koskova@kraj-lbc.cz RNDr. Karel Charvát Czech Centre for Science and Society, Prague, Czech Republic charvat@ccss.cz
