Who knew swimming pools would need to be geospatial-ised?

Local governments are constantly looking for new ways to automate data production. One major challenge faced by councils in Australia is to identify the locations for swimming pools. Citizens are required to obtain permits prior to construction, whilst ensuring pools are protected by barriers that must conform to Australian building regulations.

Most governments tackle the challenge of identifying swimming pools manually – an arduous and time consuming task that requires many man-hours. The ERDAS IMAGINE Spatial Modeler improves efficiency by allowing users to build repeatable, customized spatial models which efficiently solve complex geospatial problems. By using colour infrared imagery and a modified Normalized Difference Water Index model, ERDAS IMAGINE automates the process of swimming pool extraction.

The modified Normalized Difference Water Index processes the initial thematic raster dataset before ERDAS IMAGINE’s vector functionality allows further data processing

The ability to automatically extract features from large imagery datasets saves governments’ time and money, whilst also creating opportunities to generate additional revenue. ERDAS IMAGINE Professional is included within the Hexagon Geospatial Enterprise License Agreement, contact your local representative for more information.
