Wollongong Historical Mosaics (partial coverages)

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:MetadataTypeImageryUpdate FrequencySpatial Services releases mosaics incrementally as they completedContact DetailsRelationship to Themes and DatasetsNSW Imagery Theme of the Foundation Spatial Data Framework (FSDF)AccuracyAssessment of positional accuracy for each mosaic was undertaken using a 5km x 5km grid. An overall accuracy of +/- 20m for 95% of the 100k map sheet was targeted. The mosaic was assessed for positional accuracy at a scale of 1:10,000 using ADS 50cm imagery.Standards and SpecificationsMetadata AS/NZS ISO 19115-2, ANZLIC Metadata Profile v1.1 and ISO 19139AggregatorsDistributorsDataset Producers and Contributors
