Test map to view available imagery services from the Spatial Collaboration Portal for the Wollongong City Council Local Government Area.

From the imagery mosaics created from the Historical Aerial Photo Enhancement (HAPE) project.

Current and historic imagery form an important part of the NSW Foundation Spatial Data Framework and provide a valuable resource which is widely accessed by government and the broader community on a daily basis. As the completeness of this data base continues, its market demand also increases across a broad range of applications.

Spatial Services aerial imagery was originally captured using a variety of cameras including the Wild RC-5, RC-10 and Leica RC-30 cameras with a variety of lenses with focal lengths of 88mm, 153mm and 304mm. Images were captured in monochrome or colour during this period at a range of scales. Capture scales ranged from 1:5 000 to 1:80 000.

The Historical Air Photo Enhancement program (HAPE) not only allows the capability to search, discover and use source imagery, but also provides the delivery and viewing of enhanced historic rectified imagery mosaics. This new development means the community at large can now access and utilise spatially accurate historic imagery:
