2010 Pacific Islands Geographical Information Systems and Remote Sensing User Conference

Discussion Session 1.6

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

Goals

2

Enhance Data Sharing and Interoperability between:

Tools, Workflow, Processes & External third-party Systems

Single Data Platform, but Multiple End-User Frontends

Development

3

Common Platform developed using purely OSS components:

Data Layer – PostGIS Spatial ExtensionDifferent Data Formats converted using OGR (ogr2ogr) and PostGIS (shp2psql) utilities.

Data Exposure – OGC Web ServicesWMS, 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

Discussion
