WindPRO - Planning Wind Farms

http://www.emd-international.com/windpro/windpro-modules
WindPRO is the leading software package in the world for planning wind farms. It is a large and complex program for estimating and planning all aspects of a wind turbine farm. The user worked in a GIS-like environment.

Some examples of modules include:
WindPRO Animation: This generated a film with rotating wind turbines. Wind turbines could be placed in an artificial landscape or a photo. Neighbors and decision-makers used the animations to consider the visual impact of the turbines.

WindPRO Visual: A wind turbine or facility was realistically reproduced in a digital photo. Time of year, time of day, and weather conditions in the picture were taken into account. The results were realistic enough to make it difficult to distinguish between an artificially generated picture and a picture taken after the wind turbines were built.

Wind resource card for Denmark for any area (on land). For every 200 meters, wind conditions were calculated at four different heights over terrain (25, 45, 70, or 100 meters). Eighty million detailed calculations were made, comprised of local buildings, windbreaks, forests, lakes, and orographic and statistical wind conditions.

Care - Efficient Advertising Procurement

Care allows media agencies in the Dutch market to plan and place ads directly on the television stations through web APIs. It saves media agencies time as they do not have to contact television stations via email and phone.
