Urban and Regional Infrastructure
Airborne Sensing’s imagery has been used to support numerous urban and regional planning campaigns both in Canada and abroad. These images form the base data for both cadastral and urban infrastructure mapping. Both of these are crucial to sustainable urban renewal, with the former settling property disputes in advance and providing a predictable data base for revenue generation, and the latter enabling the development and maintenance of all municipal infrastructure.
– The digital camera system’s higher dynamic range and multispectral capability yields sharper images with more predictable detail for mapping and analysis.
– Automated image classification allows the detection of similar surface objects or attributes — e.g., to determine the presence and precise location of an invasive plant species in a neighbourhood environment, or to calculate the proportion of hard surface to vegetative surface within a municipality.
– All aerial image data can be imported into, or used directly in, GIS environments with full georeferencing and Digital Elevation Model (DEM) capabilities so that cadastral information regarding property boundaries can be overlaid immediately onto engineering information for effective alignment of new corridors or infrastructure facilities.
– Rapid and efficient development of DEMs facilitates the planning of corridors and facilities for water main and sewer networks. This was evidenced in our 2011 survey of Santo Domingo, Dominican Republic, in which mapping tools were provided for a complete upgrade of the storm and sanitary sewage systems in the city.
– Precise photogrammetric pavement surveys can be accurate up to 5cm, enabling vast possibilities for urban planning and infrastructure management.
