Interactive Mapping of Database Queries Every Map Tells A Story Tyler Mitchell and Mishtu Banerjee and LifeLine Development Team The LifeLine Team Steve Monai Andrea Eastham Ian Moss Mingchuan Lu James Wang Mishtu Banerjee Tyler Mitchell . The Problem • Technical: ease of data access • Managerial: information black box. • Complexity (of data, of decisions) The Status Quo Silos of Capability • GIS Tools don’t query databases well. • Database query tools don’t handle spatial objects well • Lots of interchange between GIS and DBs to get a simple answer • Every BUSINESS problem becomes a TECHNICAL problem Our Approach • Focus on the Query System. – Ease of Use by Non-Technical folks – Cost Effective (Use Open Source) – Low Maintenance • Various Prototypes • Work with others • Go back to the beginning… What Are Our Components • Query Tool: LifeLine • Spatial Database: PostGIS • Mapping System: MapServer • The task is “gluing” these together Defining A Query . View and Summarize Data . View A Map (and another Map) . …. And Another Map …. And More Data … and … . More Complex Spatial Queries (Prototype Mode!) … harnessing the power of PostGIS . To Do List • • • • • Complete Redesign – in Python Adding full suite of spatial operators Automated colour theming Accessing Multi-databases Advanced database schemas (“Tree” to “Forest” Graphs) • Analysis capabilities – exploratory data analysis Going Forward • A framework that works today • It needs to be made simpler, more automated, easier to install and setup • Join us! • What else can be “glued” together ??? Going Open Source • Open Source version of current LifeLine to be released as “Xaya” under a BSD/MIT style license. • Then we will rebuild it! • Help us design Xaya from the beginning!
