Book Description
This study provides evidence of the influence of DTED resolution (in regions with different terrain roughness) on Army terrain data applications. The report documents results of the U.S. Army Topographic Engineering Center's DTED resolution analysis including extensive field work and terrain visualization undertaken to investigate DTED integrity in comparison to the actual terrain. Finally, the report offers conclusions regarding DTED support for Army tactical and simulation applications.

Pages : 17
Book Description
This interim technical report discusses a project under the Advanced Visualization and Interactive Displays (AVID) in-house program to develop techniques to load and display voluminous high-resolution terrain data with sufficient visual quality and interactivity. The AVID program objectives are to develop, evaluate, and exploit new concepts in information visualization, display technology, and human-computer interaction (HCI) that provide airmen with a tailored information environment. The result of this project was the successful design and implementation of a data structure for storing, manipulating, and processing terrain data vertex information, and an algorithm that intelligently processes the information contained within the data structure.

Digital Terrain Elevation Data (DTED) Anomaly Removal Through the Use of an Interactive Fourier Frequency Filtering Process
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 34
Book Description
The Defense Mapping Agency is a producer of raster formatted elevation data in a form called DTED (Digital Terrain Elevation Data). This data is collected from digitized source maps and from optically or digitally correlated stereopairs of photographic imagery. The various means used in producing DTED sometimes introduce a striation anomaly into the data. Conventional techniques for handling this anomaly have included the use of convolution with smoothing filters. Smoothing, however, degrades the high quality resolution of the data. A more precise method specific only to the anomaly was required. To accomplish this, an interactive Fourier frequency filtering program was designed to allow analysis and filtering of the DTED in the frequency domain. The process allows the analyst to use the data's amplitude spectrum as an aid in designing an area specific low-pass, band-reject, or fan- reject filter. This technique can result in almost total elimination of the striation anomaly with virtually no degradation of the high quality resolution of the data. (Author).
