Spatial Service’s standard imagery capture program covers the entire state of NSW. Standard coverage imagery is captured and processed at a 50cm Ground Sample Distance (GSD) and is available as either 5km x 5km image modules or mosaicked to the extent of a 1:100,000 mapsheet.

The NSW Imagery web service provides access to a repository of the Spatial Services (DCS) maintained standard imagery covering NSW, plus additional sourced imagery. It depicts an imagery map of NSW showing a selection of LANDSAT® satellite imagery, standard 50cm orthorectified imageries, High resolution 10cm Town Imageries. It also contains high resolution imageries within multiple areas of NSW within DFSI, Spatial Services maintained projects and captured by AAM, VEKTA and Jacobs (previously SKM). The image web service is updated periodically when new imageries are available. The imageries are shown progressively from scales larger than 1:150,000 higher resolution imagery overlays lower resolution imagery and most recent imagery overlays older imagery within each resolution. The characteristics of each image such as accuracy, resolution, viewing scale, image format etc varies by sensor, location, capture methodology, source and processing. For specific information about the metadata for the imagery used, please refer to the individual data series within the NSW Data Catalogue. As a consequence of the variety of source data, each map displayed by the user within this map service may have a number of copyright permissions. It is emphasised that the user should check the use constraints for each image data series.

Access API Historical Imagery 1980 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: 1. Through the Historical Imagery Viewer 2.

Imagery is the product created from the use of airborne, space borne or terrestrial sensors. These technologies image the surface of the Earth to allow for the visualisation of land surface features. Imagery includes data sourced from satellite, aircraft and vehicle mounted sensors. These technologies have a range of capabilities that includes but is not limited to, the ability to record multispectral and hyperspectral data and produce products such as orthorectified mosaics and stereo-viewable imagery.

However, the horizontal accuracy of the imagery is dependent upon the resolution (GSD) of the image:Horizontal accuracy of +/-2.5 x GSD (meters) at 95% confidence level on bare open ground using RMSE x 1.73.There are two products accessible on the Historical Imagery Viewer:Historical Aerial Photo Images (HAP)These are standard 600dpi unprocessed frames as JPG’sSpatial Services has a huge repository of digitised Historical Aerial Photography. The collection has been acquired over a number of years from 1930 through to 2005. The 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 ranging from 1:10 000 to 1:80 000. Images have been digitised from either the aerial film negatives or hard copy prints up 2000dpi resolution depending on the scanned medium.Historical Aerial Photo Enhancement Product (HAPE)This is a Orthorectified product created from the Historical Aerial Photo Collection. A complete 100k coverage of individual photo frames was required for each project area for standard program capture. The Ortho rectification of individual photo frames with 60% forward overlap, that lie within and intersecting the relevant 100k map sheet. Spatial Services create the HAPE mosaics with a new process utilising Augmented Reality Modelling Software.This is an automated process using an Augmented Reality Modelling Software to produce a 3D models of an area from simple photographs.The Hybrid processing in this software enables the creation of reality meshes using Spatial Services archive of historical Air Photos, the image overlap and the photo centre points derived from the original Key Diagrams and flight reports.From the Historical Aerial Photos and the “essential information” from the Key Diagrams we are able to create a 3d mosaic of the photo frames that we can flatten to a 2D ortho photo mosaic.All images are loaded into the reality modelling engines where they go through a triangulation process with context capture using the X and Y coordinates of the photo centre and the Z coordinate created from the Flying height and other essential
