The option allows MDA to continue providing NGA with apparent changes in global land-cover. MDA said it would 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,” MDA said in a company statement. “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.”
