Identification of land use pattern
On screen digitization of the remotely sensed data was performed to identify land use in 1995 and 2002.
GIS data layers for 1995 and 2002 land uses were established, based on UTM/WGS84 coordinate. The obtained
map results were checked against the ground truth with over 11 ground sites of 3 replications. Observation
records at each site included cover type and composition, topography, landform and related land characteristics.
Allocation of the sites was based on GPS, topographic maps and satellite image. Revision of the land use map
was performed to ensure the results. Land use change between the years 1995 to 2002 was then analyzed to
understand the historical change patterns of the land.
