Land and Property Information (LPI) offers a range of aerial photography and other imagery of NSW for viewing and to purchase.
Aerial photos of your area or property
LPI regularly captures aerial imagery of areas of the state and can provide:
- imagery of most areas
- from years between 1947 and the present
- as prints or digital files that can be suitable for use in a computerised geographical information system (GIS).
Georeferenced and orthorectified photos
In order to use imagery in a GIS, it is necessary to georeference or orthorectify the imagery. To georeference something means to define its existence in physical space. That is, establishing its location in terms of map projections or coordinate systems. The term is used both when establishing the relation between aerial images and coordinates but also to determine the spatial location of other geographical feature.
Orthorectification removes distortions due to height, altitude of the aircraft and the terrain that has been photographed. This allows measurement to a precision in line with the scale of the photography.
Free viewing of SIX imagery
Using SIX Maps http://maps.six.nsw.gov.au you can zoom into any portion of the state and see aerial imagery, property boundaries and streets, and other free online features.
Aerial images from the past
Aerial imagery provides a valuable source of information for studying, monitoring, forecasting and managing natural resources and human activities.
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. Photos below demonstrate how Breakfast Point in Sydney has changed over a 60 year period.
You can make historical comparisons using SIX Maps http://maps.six.nsw.gov.au.
For other timeframes and locations, you may need to purchase historical aerial photos.
