Abstract: A method and system to provide visualization of high resolution terrain for use in real-time simulation for digital image displays that is derived directly from source data including imagery, classification, elevation and vector data at run-time with little or no off-line manipulation of the source data. The fidelity of the visualization is scaled while based on the graphic system's capability readily available worldwide data exists for elevation vector and import runway data. System provides for facilitating run-time processing of source data utilizing a project file which lists each source file, desired attribute mapping and whether the source is enabled or disabled. For each source file a source proxy object is created in memory which references the target source file. The source proxy objects are stored in a vector manager in a spatial index to quickly determine which data sources intersect a given area. A spatial index can be queried for the proxies covering a requested geographical location.
