Geoinformatics

in 2004 it was FOSS4G!

FOSS/GRASS User Conference in Bangkok

FOSS4G2006 held at Lausanne, Switzerland http://2006.foss4g.org/

FOSS4G2007 held at Victoria, Canada http://2007.foss4g.org/

FOSS4G2010 held at Barcelona, Spain http://2010.foss4g.org/

FOSS4G2011 to be held at Denver, USA http://2011.foss4g.org/

FOSS4G2012 to be held at Beijing, Chinahttp://2012.foss4g.org/ ＣＡＮＣＥＬＬＥＤ

FOSS4G 2013 Nottingham, UK http://2013.foss4g.org/

FOSS4G is now a worldwide phenomenon

Home BrewJapan, Korea, India, Malaysia, The Philippines…and Asia

In 2013, PaaS4G! is round the corner

Platform as a Service for

(sounds like 4) Geoinformatics

(or geospatial) applications*

*In other words CloudGIS

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

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

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.

http://zoo-project.org

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

Example

HelloWorld.py

def HelloPy(conf,inputs,outputs):outputs["output1"]={"value": "helloworld"+inputs['Name']['value'],"datatype": "string"}return SERVICE_SUCCEEDED

HelloWorld.zcfg overview

[HelloWorld]Title = Get the HelloWorld string.serviceProvider = test_serviceserviceType = Python<DataInputs>[Name]Title = HelloString<LiteralData>DataType = string</LiteralData></DataInputs>

<DataOutputs>[output1]Title = HelloString<LiteralData>DataType = string</LiteralData></DataOutputs>
