In 2013, PaaS4G! is round the corner
Platform as a Service for
(sounds like 4) Geoinformatics
(or geospatial) applications*
*In other words CloudGIS
![Page 5: PaaS4G - Towards a Service Oriented Platform for ...](https://reader033.fdocuments.us/reader033/viewer/2022060317/6294999b10fd375802130955/html5/thumbnails/5.jpg)
INTEROPERABLE SERVICE ORIENTED
GEOSPATIAL ARCHITECTURE
Automate and orchestrates WPS, WMS, WMTS and
WFS.
Geoprocessing driven by a collection of WPS
Services
Vector Data as WMS and WFS
Raster data is displayed as WMS
Both datatypes as WMTS in final Web-GIS
applications
![Page 6: PaaS4G - Towards a Service Oriented Platform for ...](https://reader033.fdocuments.us/reader033/viewer/2022060317/6294999b10fd375802130955/html5/thumbnails/6.jpg)
WHAT IS WPS ?
Web Processing Service is designed to standardize the way thatGIS algorithms are made available on the Internet.
WPS specifies a mean for a client to request the execution of a spatialcalculation from a service.
WPS intends to automate geoprocessing by employing geospatial semantics in a service-oriented architecture (SOA).
Open Geospatial Consortium interoperability standards since 2005
WPS Standard was published and accepted as Standard in 2007
http://zoo-project.org
![Page 7: PaaS4G - Towards a Service Oriented Platform for ...](https://reader033.fdocuments.us/reader033/viewer/2022060317/6294999b10fd375802130955/html5/thumbnails/7.jpg)
Short WPS Overview
Web Processing Service defines three requests :
GetCapabilities (as almost all the OWS Standards)
Provides a full overview of all the processes available on the therequested server.
DescribeProcess Provides detailed description ofService.
Execute Provides a way to run the Service and ask for the
ResponseDocument or RawdataOutput.

Why use WPS ?
WPS opens the door to interoperability with Web GIS!
Input:
- Shapefile, MapInfo...
- GeoTiff, DEM, Lidar …
- KML, GeoJSON...
- PostGIS, Oracle, ArcSDE...
- WFS, WCS, CSW...
Output:
- Shapefile, MapInfo...
- GeoTiff, DEM, Lidar …
- KML, GeoJSON...
- PostGIS, Oracle, ArcSDE...
- WMS, WFS, WCS...
WPS allows the processing and conversion of GIS data online
