The Problem
• Immigration to Jordan results in ongoing and explosive urbanization
• Developers ignore and bulldoze archeology

Incomplete list of Requirements…
• Must capture and polygonal extent of sites… polygons, not just points
• Supports robust spatial data validation and integrity rules
• Robust Reporting Capabilities
• Sustainability: DoA will be the final owner
• Flexible: expected that system will be redeployed in other Middle Eastern countries with minimal expense

MEGA-J Technical Components…
Database: PostgreSQL with PostGIS Supports native spatial data, accessible with SQL in a robust relational
database
Client Application: Quantum GIS Spatial data editing, ad-hoc outputs
Data Publishing Platform: GeoServer Web-enables spatial data using open standards
Rendering Environment: OpenLayers with Google Basemap Data Java Script map widget creator. Consumes spatial information from most
any standards-based source

Why Open Source?
Remember the requirements…
Sustainability:• Proprietary s/w maintenance = one year of typical Jordanian
government salary• In the end, DoA will own the system• Other (potentially Third World) countries will deploy the system
in the future
Technical:• Data validation, integrity supported (based on spatial criteria)• Access to database by multiple GIS clients• Complex reporting capabilities, both spatial and non-spatial

Project Status
• Beta data model created
• Workflow (using QGIS and PostGIS) deployed in Jordan for initial data capture
• Final Data Model and Code Base currently under development
• RC 1 expected in Spring 2009
