ATIC - Alberta Terrestrial Imaging Centre

Joint venture between the University of Lethbridge & Iunctus Geomatics Corp.

Incorporated in mid-2005

Our mandate:

Develop the Canadian academic market for SPOT satellite data

Applied research using remote sensing while working with end users to develop commercial products for managing natural resources and protecting the environment

5

Remote Sensing

The science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation.

Remote sensing is an applied science which helps in understanding many activities such as forestry, land usage, agriculture, environmental protection, water management, etc.

SPOT - Major Applications Land & Topography

Land development planning Tracking municipal infrastructure Accurate mapping Flight simulators

Agriculture Yield enhancement

Forestry Monitoring timber rights & harvesting Assessing fire damage & pest infestation

Environmental Protection Monitoring mining and oil & gas activities

Water Management Watershed mapping & monitoring Wetlands mapping Glacial changes

Utilities Telecom – cellular tower placement & infrastructure tracking Powerlines and pipelines – right-of-way corridors

Military Mission planning

24

Why SPOT Imagery Extensive coverage of Canada with high & medium resolution optical imagery

at academic prices

Ideal mix of resolutions for most applications: Spatial Spectral Temporal

Cost effective - price/performance “sweet spot” Extensive archives – Canada and global User tasking with “real time” delivery Wide range of uses
