Overview

ArialPhotography
Leading Edge Geomatics provides advanced aerial photogrammetric solutions for a variety of markets and industries. LEG deploys the latest camera systems that are individually paired with gyro-stabilized platforms to one of the seven aircraft in our fleet. With several camera solutions, gyro mounts, and aircraft, we can ensure quality imagery, high accuracy, and maximum collection efficiency for any aerial mapping project. Our camera sensor portfolio includes 80-150 Megapixel cameras that provide high-quality, high-resolution imagery. We have a team of experienced photogrammetrists on staff that ensure every project is delivered on time, meeting the highest quality standards.

LEG transforms imagery into a variety of unique products, individually tailored to our customers’ needs, including:
• Orthorectified RGB and CIR imagery
• True Orthorectified Imagery
• Stereo Models
• Oblique Imagery

 

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.
