ABSTRACT
The classification of data collected by a multispectral sensor had done by using the multispec
software. The data was analyzed through a number of processing steps to achieve the required
classification of the spectral data to adequate, exhaustive, separable classes. This research
discusses the analysis of the multispectral data gathered by an airborne. It was found that this
classification is depended on many factors, e.g. clustering process, the spectral band
utilizedand final requirement. This study compares two systems of calculation polygons area,
by using multispec software and GIS tool. The results showed that the area of classified
polygons improved by using GIS tool.
That's the smart thinknig we could all benefit from.
