We propose an elevation-based approach to parking lot structure analysis from aerial imagery. In contrast to image-based methods, the new approach treats parked vehicles as 3-D microstructures and attempts to locate them in the elevation domain. The STME (Surface Texture and Microstructure Extraction) system is applied to the elevation map to extract the 3-D microstructures. A hybrid applicatio...

For the generation of topographic maps generally the ground elevation rather than the surface elevation is required, which can be realized, if at all, only with large wavelengths that penetrate the vegetation foliage. This paper reports about a project in the Brazilian Amazon region where Aerosensing's P-band airborne interferometric SAR has been used to map a part of the rainforest. The P-band...

Recently we developed a periodic surface model to assist the construction of nano structures parametrically for computer-aided nano-design. In this paper, we study the properties of periodic surfaces for degree elevation and reduction. Degree elevation approaches are developed to incrementally increase shape complexities, including native, variational, and boundary constrained elevations. A gen...

Over three million hectares of salt-affected soils characterized with high salinity and sodicity caused serious land degradation in Songnen Plain, northeast China. Soil salinity–sodicity heterogeneous distribution under microtopography is usually influenced by several environmental factors. The side direction movement of soil water driven by water from depression is the key factor that aggravat...
