dc.description.abstractCombining different types of data from varying sensors has the potential to be more accurate than a single sensor. This research fused airborne LiDAR data and WorldView-2 (WV-2) multispectral imagery (MSI) data to create an improved classification image of urban San Francisco, California. A decision tree scenario was created by extracting features from the LiDAR, as well as NDVI from the multispectral data. Raster masks were created using these features and were processed as decision tree nodes resulting in seven classifications. Twelve regions of interest were created, then categorized and applied to the previous seven classifications via the maximum likelihood classification. The resulting classification images were then combined. A multispectral classification image using the same ROIs was also created for comparison. The fused classification image did a better job of preserving urban geometries than MSI data alone and suffered less from shadow anomalies. The fused results however, were not as accurate in differentiating trees from grasses as using only spectral results. Overall the fused LiDAR and MSI classification performed better than the MSI classification alone but further refinements to the decision tree scheme could probably be made to improve final results.en_US
