OX-Framework

  • OGC Web Service Access Framework

    • addresses developers

    • customizable and extendable system of cooperating classes

    • reusable design

    • applicable for client & server applications


Example clients
Example Clients

  • Rich Client

  • Web Map Server

  • Thin SOS Client, Thin SWE Client

  • uDig Plugin

  • ArcGIS Plugin



Oxf web map server
OXF Web Map Server

  • WMS-Frontend encapsulating a SOS

  • Conforms to WMS 1.1.1

  • Mapping of sensor data sets to layers

  • Existing WMS clients can access sensor data

  • Opaque Service Chaining

  • “Rendering Engine


Thin swe client
Thin SWE Client

Web-based application to access sensor data

Display of time series

Combination of different phenomena

Ajax based

Export: PDF, Excel and CSV

Supports SOS, SES




Sos gis plugins
SOS GIS Plugins

  • uDig

  • ArcGIS

  • R


Uncertainty visualisation in uncertweb
Uncertainty Visualisation in UncertWeb

  • Necessaryformodelinputs, outputsand intermediate steps

  • Support understandingandcommunicationofuncertainties

  • Support UncertWeb encodings (NetCDF-U, O&M, UncertML)

  • Aim: Develop a web-basedinteractivethinclient

Usability survey
Usability Survey

  • Web basedsurvey (usingLimeSurvey)

    • Different usergroups

      • GIS andstatisticsexperts vs. non-experts

    • Questions on fivemethods

      • 3 static (adjacentmaps, contours, symbols)

      • 2 interactive (UncertWeb client, Aguila)

    • Evaluatingperformanceandpreference

      • Methodswith high performance + high preferencewereconsideredasuseful
