D2.5 Proof -of-Concept Evaluation for Modelling Time and Space. 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 )
E N D
Motivation (I) • IncreasingamountofgeospatialdatabeingpublishedasLinked Data • LinkedGeoData • OrdnanceSurvey, IGN Spain, IGN France, etc. • European Environmental Agency • ... • Different vocabularies (heterogeneity) • GeoSPARQL • NeoGeo • W3CBasic GeoVocabulary • theISAProgrammeCoreLocationVocabulary • schema.org’scoordinates and polygons 11/02/11
Motivation (II) • Besides, geospatial data can be combinedwithstatistical data, sensor data, etc., whichalsoprovide a temporal perspective • Again, different (standardised) vocabularies • W3C RDF Data Cube • Semantic Sensor Network Ontology
Deliverableobjective • Implement and describe a prototypetoolthatmakes use of data accordingto a combination of thesevocabularies • Map4RDF-iOS • https://itunes.apple.com/en/app/map4rdf-lite/id828604407?mt=8 • Developed in parallelto Map4RDF • http://map4rdf.oeg-upm.net/ • Two demos presented • ISWC2013 Semantic Sensor Network workshop (SSN2013). Sydney, October 2013 • W3C/OGC LinkingGeospatial Data Workshop. Google Campus, London, March 2014
Map4RDF-iOS Map4RDF-iOS Description • Endusers • Citizens/ non-geographers / LGD providers 5
Map4RDF-iOS mainfeatures Map4RDF-iOS Description • iOSmobiledevices(v5 tov7) withoptimisedmemorymanagement • Multiplemap servers (OSM, Google, Apple, Nokia) • Data • Statisticaldata modelled as W3C's DataCube • Multiplegeospatial data models: W3C Geo XG, GeoLinkedData, and WKT/GeoSPARQL • Clustering of data points • Customizablebyendusers, e.g. definition of SPARQL endpoints and queries 6
Map4RDF-iOS limitations Map4RDF-iOS Description • Single platform (iOS) • WorkingwithTitaniumAppceleratortoprovide a combination of native + HTML5 widgets • Onlysupportfor (non-authenticated) SPARQL endpoints. • Onemap server and oneendpoint at a time. • No data edition • Connectivity module tosave & share configurations, snapshots, and LGD datasets 10
