Existing registered users have been transferred to the DPIE subscription.Joe Fedewa has been writing about technology for over a decade. In 2020/21 this innovative service will be facilitated by the Department of Planning, Industry and Environment (DPIE). In 2019/20, Spatial Services facilitated a Whole-of-Government daily satellite imagery subscription through Planet Labs. NSW Government agencies are also able to contact the Service Delivery team to request access to individual mosaics and state wide mosaics from 20. The 2020 capture will soon be available as a basemap via the Spatial Collaboration Portal. SPOT 6/7 Imagery 2019 can be viewed as a basemap on the Spatial Collaboration Portal. Bushfire affected areas throughout NSW can be viewed prior to and post the devastating season experienced in 2020. Used alongside our fourth quarter 2019 Spot Imagery release, monitoring urban expansion and land use/cover changes at a small, medium or large scale, to help better observe and understand the evolution of urbanisation and advance the sustainable development process are all achievable. The imagery from this latest capture will be of particular use to agencies working on a range of change management initiatives. The provision of this dataset was awarded by tender to Geospatial Intelligence Pty Ltd who has partnered with Geoimage Pty Ltd and Airbus Defence and Space. So far two satellite imagery mosaics have been captured at 1.5m resolution (from 20) as part of the Spatial Services Whole-of-Government initiative. More recent satellite imagery is available as part of Spatial Services SPOT 6/7 mosaics. Satellite imagery, designed to aid in management of resources and monitoring of oceanic and terrestrial changes, is available from Satellite Pour l’Observation de la Terre (SPOT 5), a system of satellites launched in 2002. This imagery can be useful to organisations involved in planning and managing land use and the natural environment. Spatial Services contributes the NSW LiDAR imagery to the national data set, Elevation and Depth – Foundation Spatial Data (ELVIS). Spatial Services has access to specialised Radar, Light Detection and Ranging (LiDAR) data and satellite imagery which depict height information, vegetation, floods and other special conditions and features. Orthorectified imagery is available to purchase, by contacting the Service Delivery team. This allows precise measurement in line with the scale of the photography. Orthorectification removes distortions due to height, altitude of the aircraft and the terrain that has been photographed. The term is used both when establishing the relation between aerial images and coordinates and also to determine the spatial location of other geographical features.

To georeference something means to define its existence in physical space, that is establishing its location in terms of map projections or coordinates. To use imagery in a GIS, it is necessary to georeference or orthorectify the imagery. Georeferenced and orthorectified photographs This imagery can be viewed as a basemap on Six Maps or the Spatial Collaboration Portal. The Spatial Services Imagery Capture Program has also captured more recent aerial imagery over NSW. Due to the size of the file and JP2 format, users may have issues opening the images if they do not have appropriate software. This imagery is supplied in a digital format by FTP link as an unprocessed JPEG2000 (JP2). Ordering higher resolution Historical Imageryįor customers who want to purchase a higher resolution version of historical imagery, this product is still available, and users can contact the Service Delivery Team for further information. Over Sydney, these images can also be viewed as a mosaic, allowing users to explore the city and its history. Users can search an area of interest, and look at thumbnails of each available frame and download a 600dpi version of a chosen image, free of charge. The new Historical Imagery Viewer, as part of the Spatial Collaboration Portal, allows users to search, discover and download historical imagery from our library, dating back to the 1930s. Free viewing and download of aerial imagery Obtaining aerial photos from different periods can be a useful way to research the history of an area or to verify different uses of land over time. Imagery from the pastĪerial imagery provides a valuable source of information for studying, monitoring, forecasting and managing natural resources and human activities. Aerial Imagery is captured across NSW and is available with a range of years from 1930s through to current. Spatial Services holds a wide range of aerial photography and other historical imagery of NSW for viewing and purchase.
