Powering Applications with Map Data Layers Extracted from Satellite Imagery

LAND INFO's off-the-shelf global land-use/land-cover data are ideal for visualization/simulation, wireless network planning, base mapping, presentation graphics and other applications requiring affordable large-area coverage.

Simulation-based virtual training systems require geo-specific visual environments for realistic training of military and security forces, but scenarios often are based in areas of the world with limited map data availability. LAND INFO creates map datasets optimized for visualization and simulation (viz/sim) applications on a worldwide basis by leveraging the global reach of com-mercial high-resolution optical satellite imagery.

Depending on the map data layers and attribution required, a blend of manual and semi-automated techniques are employed to create the data. LAND INFO’s custom map datasets have been used  effectively in skills trainers for small arms, gunnery, convoy/route clearance, armor and aviation.

Geodata Advantage

Used by pilgrims during the Hajj, Mina (Tent City) and Jamaraat Bridge are located at the eastern outskirts of Mecca, Saudi Arabia. Realistic digital environments are created by including detailed features such as fences, compound walls, towers and other infrastructure in addition to basic layers such as transportation, buildings, hydrology and vegetation. Rich feature attribution, such as road type, is also included. The topology that is employed maintains visually correct databases, e.g., building footprints don't intersect with roads or hydrology. Shared nodes at all road intersections permit routing applications.

At project inception, LAND INFO will analyze the required layers and level of detail to recommend appropriate source data, making sure the customer thoroughly understands all options, including the use of archive imagery vs. new collection. During initial image processing, ensuring high absolute accuracy allows multiple data types from different sources to be integrated while maintaining high relative accuracy, resulting in visually correct environments.

LAND INFO’s topologically correct map data layers afford a significant cost and time savings for customers who want to finalize their own visual databases, or turnkey 3-D models can be delivered. Additionally, LAND INFO can custom create data from a wide range of collection platforms or correlate a customer’s existing data to satellite imagery for improved accuracy and currency.
