MacDonald, Dettwiler and Associates (MDA)... Land Surface Exams (Imagery)

[SatNews] MacDonald, Dettwiler and Associates Ltd. (TSX: MDA) has announced that the U.S. National Geospatial-Intelligence Agency (NGA) has exercised...

...a one year option valued at US$4 million to continue the provision of apparent changes in land-cover anywhere around the globe. MDA will deliver changes for more than 100 million square kilometers of the Earth’s land surface.

Overlaying satellite images from multiple dates, MDA’s sophisticated software identifies changes in land-cover that persist regardless of seasonal changes or weather effects. Changes identified are typically caused by human activities. Knowing where these changes occur allows the analyst to focus only on the areas of change when updating global map databases. This allows map updating to be done more frequently in rapidly changing areas and less frequently elsewhere, significantly improving the customer’s efficiency.
