12-meter WorldDEM Product Availability – A Monthly Update

For three years, Airbus’ twin high-resolution radar satellites, TerraSar-X and TanDEM-X, have imaged the entire land surface of our planet multiple times to create the first ever global 12-meter (m) elevation model. The WorldDEM is ideal for all mapping projects requiring accurate elevation models including orthorectification, floodplain determination, mineral exploration and hydrocarbon development.

During February, sections of Africa, Europe, the Middle East and South America were made available. WorldDEM areas that are available to order take a minimum of 10 days to deliver.

    Good Sir,
    Please may i ask you what it sound like if i request your organization provide me with this 12m DEM primarily for my Doctorate research in the Niger Delta Region of Nigeria.

    These is an appeal seeing i would not be able to afford the cost but would be ok if you demand i site it and acknowledge your organization after usage in my thesis.
    Thanks in anticipation
