The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level.The Latin word terra (the root of terrain) means "earth.". 2014 IEEE International Conference on Robotics and Automation (ICRA). This paper presents a self-supervised classification approach to learning the visual appearance of terrain classes which relies on vibration-based sensing of wheel-terrain interaction to identify these terrain classes. First, area segmentation was performed globally with the logarithmic value of slope gradient and the local convexity calculated from the DEM. The objective is to classify terrain into 5 types: building, green zone, car park, road and canal.

Proceedings of the 8th International Conference on Computer Recognition Systems CORES 2013. en 16 The dispute in the main proceedings concerns the tariff classification of three Kawasaki models of all terrain vehicles (KVF‐360 4x4, KVF‐650 4x4 and KVF‐750 4x4). Next, the SVM, ELM, and DBN classification algorithms for hyperspectral image terrain classification are analysed and compared in terms of accuracy and consistency. However, for the reason explained above, manually classifying terrain for an single landing site is impractical, not to mention doing so for the eight candidate sites currently considered.
