Knowing “what, where, and when” you wish to have us capture photos is important, as we tailor our process to each project. Utilizing remote sensing skills (theoretical and practical) we try to deliver the best product for your mapping project. We study project successes and failures, and we methodically iterate our tools, techniques, methodology and framework. Success with your aerial photo project, depends on scientific method, not just the successful adaption of technology.
If you are interested in ordering new air photos or orthophoto mosaics, there are a number of important criteria to consider:
There are two ways to show us your area of interest:
Oblique aerial photography offers a unique perspective compared to traditional vertical air photos. Above ground features are more pronounced and many people find that objects are easier to distinguish on oblique air photos.
We integrate our oblique air photos into Flyeye viewing software (www.flyeye.ca). Flyeye is available as an ArcMAP plugin that accurately displays of georeferenced air photo imagery. Some key features of our oblique imagery are:
Photogrammetric aerial cameras have been around since the 1930’s and aerial surveys were common after WWII. These historical air photos can be scanned, orthorectified, and mosaicked into an orthophoto.
Terrasaurus has been working closely with the University of British Columbia and mapping consultants, to processes historical air photos into quality orthophotos. We have developed certain techniques:
If your site is small in size (less than 250Ha) and accessible by a vehicle, then it can be flown by our UAV. Our fixed-wing UAV delivers great imagery and is a cost-effective alternative for small sites. If you require a larger area, our aerial camera in the manned aircraft becomes more efficient (and safer).
UAVs are lightweight, thus only able to carry a small digital camera. Most UAVs carry an APS-C sized digital camera. The coverage is much smaller than our professional aerial camera. Therefore more photos are required per equal area, thus the UAV is only efficient for smaller-sized projects.
