The increased availability of high-resolution satellite images and aerial photography in support of 3D modeling with detailed terrain surface elevation models assists urban planners and municipal managers to create a model and visualize the urban space in three dimensions.

Just a few years ago, the main input data for the production of digital city models and 3D city models were aerial images, terrestrial images, map data, and data derived from classical surveying. The process of geospatial information extraction from these sources was performed manually, but today with the availability of high-resolution Satellite sensors, satellite images can support the generation of a three-dimensional dense, geo-referenced terrain surface.

3D models can be used as a user-friendly interface for querying the urban environment as a Geographic Information Systems (GIS), for hyper-linking Web-based information, for visualizing model results, and for accessing functional simulation models.

3D terrain modeling and visualization application requires good detail pertaining to the terrain features and terrain slopes for critical project decisions, an accurate digital terrain model (DTM) and a digital surface model (DSM) must be available.

Satellite Imaging Corporation(SIC) can provide customers with 5m digital surface models (DSMs), 2m digital elevation models (DEMs), and a detailed, orthorectified satellite image mosaic at 0.8m resolution. Our company can produce clear, captivating simulated views of almost any location from high resolution satellite sensors and aircraft imaging data.
