D2.5Proof-of-Concept
Evaluation for Modelling Time and Space
Slide 2 of x11/02/11
Motivation (I)
• Increasing amount of geospatial data being published as Linked Data• LinkedGeoData• OrdnanceSurvey, IGN Spain, IGN France, etc.• European Environmental Agency• ...
• Different vocabularies (heterogeneity)• GeoSPARQL• NeoGeo• W3CBasic GeoVocabulary• the ISAProgramme Core Location Vocabulary• schema.org’s coordinates and polygons
Slide 3 of x
Motivation (II)
• Besides, geospatial data can be combined with statistical data, sensor data, etc., which also provide a temporal perspective
• Again, different (standardised) vocabularies• W3C RDF Data Cube• Semantic Sensor Network Ontology

Deliverable objective
• Implement and describe a prototype tool that makes use of data according to a combination of these vocabularies• Map4RDF-iOS • https

• Developed in parallel to Map4RDF• http://map4rdf.oeg-upm.net/
• Two demos presented• ISWC2013 Semantic Sensor Network
workshop (SSN2013). Sydney, October 2013• W3C/OGC Linking Geospatial Data Workshop.

Map4RDF-iOS main features
– iOS mobile devices (v5 to v7) with optimised memory management
– Multiple map servers (OSM, Google, Apple, Nokia)
– Data– Statistical data modelled as W3C's DataCube– Multiple geospatial data models: W3C Geo XG,
GeoLinkedData, and WKT/GeoSPARQL
– Clustering of data points– Customizable by end users, e.g. definition
of SPARQL endpoints and queries

Map4RDF-iOS limitations
– Single platform (iOS)– Working with Titanium Appcelerator to provide
a combination of native + HTML5 widgets
– Only support for (non-authenticated) SPARQL endpoints.
– One map server and one endpoint at a time.
– No data edition– Connectivity module to save & share
configurations, snapshots, and LGD datasets
