CALIBRATING CELLULAR AUTOMATA OF LAND USE/COVER CHANGE MODELS USING A GENETIC ALGORITHM
Stochastic spatial simulation Genetic algorithm Amazon deforestation landscape pattern fragmentation connectivity
2015/9/21
Spatially explicit land use / land cover (LUCC) models aim at simulating the patterns of change on the landscape. In order to simulate landscape structure, the simulation procedures of most computatio...
Multi-image Shape-from-shading: Derivation of Planetary Digital Terrain Models Using Clementine Images
High-resolution DTM extraterrestrial surfaces reconstruction method
2015/7/8
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using only conventional
digital image matching is a problem. The matching methods need at least ...
