Abstract

Texture has a wide range of applications in the field of image processing. The application of existing texture research methods in DEM is mostly texture feature extraction and index calculation. However, the formation of landforms is caused by terrain relief. The existing texture analysis methods generally have a deficiency in the reflection on the human visual system. In this paper, the visual boundary lines, visual outline lines, and skeleton lines were used as the DEM relief textures that can visually reflect terrain relief. Then the extraction method is refined in conjunction with digital terrain analysis theory. Finally, a multi-dimensional visualization model of DEM relief texture was built, which achieves a better visual effect and provides new ideas for digital terrain analysis, and also has a wide range of popularization and application value.
