Hyperspectral remote sensing images are consisted of several
hundreds of contiguous spectral bands that can provide very rich
information and has the potential to differentiate land cover classes with
similar spectral characteristics. LIDAR data gives detailed height information
and thus can be used complementary with Hyperspectral data. In
this work, a hyperspectral image is combined with LIDAR data and used
for land cover classification. A Principal Component Analysis (PCA) is
applied on the Hyperspectral image to perform feature extraction and
dimension reduction. The first 4 PCA components along with the LIDAR
image were used as inputs to a supervised feedforward neural network.
The neural network was trained in a small part of the dataset (less than
0.4%) and a validation set, using the Bayesian regularization backpropagation
algorithm. The experimental results demonstrate efficiency of the
method for hyperspectral and LIDAR land cover classification.
