Automated generation of satellite-derived information is a powerful tool for compliance monitoring and incident detection, however, it's not without its challenges.


Satellites now pass over New Zealand several times a day, collecting images of any given area of the country at metre-scale resolution. This increase in the availability of regular, high-quality, georeferenced imagery can offer scalable solutions for compliance monitoring and incident detection.  Reconnaissance that once required physically visiting an area of interest can now be carried out from a computer, allowing field and front-line responders to deploy on an incident basis, improving team efficiency and effectiveness.  Examples of monitoring and detection applications are found in construction activities, logging operations, detection of spray drift into ecologically sensitive areas, and the detection of pollution events in surface waters. However, the promise of satellite-derived solutions is not without its challenges. This presentation uses learning outcomes from Xerra-built urban-development and water quality monitoring tools to demonstrate how challenging factors such as cloud cover, cost of imagery, and classification problems can be overcome.
