Case Studies – BC

Hectares BC – Biodiversity BC on behalf of a broad partnership

Biodiversity BC and its government and non-government partners were looking for regional-level environmental statistics. Refractions proposed a new approach to generating GIS summaries, using the power of a relational database and web tools to provide GIS analysis to users who previously had no access to it.

Refractions provides full-service support for the British Columbia Digital Roads Atlas – systems design, maintenance, data conflation, client service, and rapid response.

Line Cleaner – BC Ministry of Forests

The British Columbia Ministry of Forests needed a tool to conflate multiple roads databases into a single working layer. Refractions delivered the algorithms and a user interface based on the uDig platform.

Refractions developed an ArcMap extension to automate the calculation of standard reports joining a massive shape-file archive with a large Oracle database.

To integrate ocean observations with the Canadian Geospatial Data Infrastructure (CGDI), the British Columbia government contracted to build an OpenGIS™ standard portal. Refractions delivered a system that allowed on-the-fly discovery and viewing of WMS layers, on-the-fly re-styling of WMS layers, and session management. The system used ArcIMS, OpenIMF, J2EE, and Mapserver.

Refractions integrated a mapping system based on the Mapserver open source web mapping engine into the existing VISTA on-line analytical (OLAP) data warehouse infrastructure. The new system acts as another “view” of the data, so any data query created in VISTA can now be viewed as a table, a chart, or a colorful thematic map.

Refractions built a web-based utility for searching boundaries over the web, using Oracle, ArcIMS, and IMF to provide an interactive map of the data.

Geographic Data BC needed a system to quality control planimetric mapping submissions from third parties. Refractions built a system that used FME to run quality operations and ArcView 3.X to provide a user interface for semi-automated manual operations.

Archaeology Branch had large number of bad records in their GIS coverage and database with poor linkages between the spatial and attribute sides of their system. Refractions analyzed their complete database algorithmically and generated a new clean coverage and database update script to bring the two sets into sychronization.
