1. Open Source GIS Web Mapping Solutions Sachindra Singh ICT Systems Developer 2010 Pacific Islands Geographical Information Systems and Remote Sensing User Conference Discussion Session 1.6

2. Overview 1 2010 SOPAC ICT development initiative to bring together disparate: GIS Data Systems GIS Data Formats SHP Files, MapInfo Files, GML Files, etc Common, Searchable, Scalable Data Platform Singular GIS and Spatial Data Repository

3. Goals 2 Enhance Data Sharing and Interoperability between: Tools, Workflow, Processes & External third-party Systems Single Data Platform, but Multiple End-User Frontends

4. Development 3 Common Platform developed using purely OSS components: Data Layer – PostGIS Spatial Extension Different Data Formats converted using OGR (ogr2ogr) and PostGIS (shp2psql) utilities. Data Exposure – OGC Web Services WMS, WFS, WCS - enables any modern desktop or web GIS tool to consume GIS data/layers Data User Interfaces Web Map Interface (Searchable, Bandwidth-aware) Google Earth (KML file generation from Data Layers within the repository) Other potential interfaces (desktop, web, or mobile) can be easily development using OGC Webservices

5. Discussion 4 What priority does your organisation place on a single GIS data platform and/or enabling data sharing using industry standards such OGC WebServices or Simple Features SQL?
