Imagery subscription services
Landgate's SLIP Imagery service gives you access to aerial imagery captured over Western Australia since 1948. There are three services to choose from depending upon your organisation’s requirements.
WA Now
This base layer imagery is a whole of state layer configured as a flattened and seamless single service. It can be used as a background in conjunction with other data services to provide a spatial reference and contains the most current 1:100,000 aerial imagery tiles, aboriginal community, regional and town site mosaics.
Perth Metro
The Perth Metro service has recently combined Perth’s bi-annual capture (Perth2) and quarterly capture (Perth4) imagery services into a single service.
It provides Perth metropolitan aerial imagery as individual mosaics from 1948 through to the present day.
Perth was captured annually until 2010, became bi-annual in 2011 and then quarterly in 2015 – captured in each of the four seasons. In 2018, it reverted to a bi-annual program.
Imagery captured prior to 2007 has been converted from individual, analogue frames to seamless digital orthorectified mosaics. The scan resolution equates to approximately 20cm GSD.
The ground resolution of our digitally captured imagery varies between 10 and 15cm GSD.
NB: not all imagery captured prior to 2000 is currently available in this service; it is being added progressively over time and made available at no additional cost to the subscriber.
WA Regional
This service provides access to all available regional imagery as separate layers from 1987 to the current year. This includes the most current 1:100,000 aerial imagery tiles, aboriginal community, regional and town site mosaics.
