With many applications, aerial photography can offer users an advantageous perspective on projects and planning.

Leading Edge Geomatics owns and operates four cameras:

• Three Applanix DSS
• One Microsoft UltraCam Lp

With our advanced equipment, Leading Edge can provide you with resolutions between 7.5 and 30 cm. Further to basic aerial photos, Leading Edge can process your data to deliver orthorectified imagery, or stereo models.


Orthorectified Imagery

Halifax_DowntownDigital aerial imagery is orthorectified using digital elevation models  produced from automated matching of imagery or LiDAR elevation data to produce orthophotos. Orthophotos are then combined to create a seamless orthorectified mosaic of the project area.
Orthorectified Imagery products are designed for users seeking an imagery product that is GIS ready, as well as users who require a high degree of absolute geometric accuracy for analytical applications. The products are radiometrically, sensor corrected, and orthorectified with a fine digital terrain model using the map projection and datum requested by the customer. For order polygons that require more than one strip, users have the option to have their products mosaicked into a single product.

Stereo Models

Stereo models enable the user to view the overlapping area in adjacent pairs of photographs for the purpose of viewing and measuring three-dimensional points in the imagery.

Basic Stereo Pair Imagery products are designed for users with advanced image processing capabilities and photogrammetric tools. This product is ideal for Digital Elevation Model (DEM) generation, 3D visualization, and feature extraction applications. Basic Stereo products are collected in-track, on the same orbit, and are acquired at angles optimal for stereo viewing and manipulation.

Oblique Imagery

Oblique imagery is acquired at an angle, as opposed to the traditional vertical imagery used in orthophoto production, which is taken at nadir. Oblique imagery enables the user to easily interpret the imagery and offers side views of objects and structures on the ground. High or low oblique imagery is possible depending on the users needs and desired angle of inclination from nadir.
