Color and color infrared aerial photography with multi-date and multi-scale were taken over the Sakaerat Environmental Research Station (SERS) of 81.05 km2 which was used as the study area. Forest land-use classification and vegetation maping were performed from these photographs. Findings showed that large scale of 1: 15,000 color and color infrared photographs provided more details for land-use classification: e.g. stand density, forest community, development stage, degree of disturbance, dominant tree species distribution were identified. Multi-date color and color infrared photography also providedd information on phenological characteristics, forest fire (newly burned, old burned area), forest ecotone, and agricultural cropping patterns. Land-use classification map compiled from 1: 15,000 scale of color and color infrared photographs was used as a control map for accuracy comparisons. The results revealed that color and color infrared of 1: 50,000 scale providedd highest accuracy (86.5%) followed by visual interpretation of LANDSAT (74 percent) and digital image analysis using dry and wet season frame, (73.7 percent and 69.5 percent) respectively. The photo interpretation, selective and dichotomous keys, were also constructed from the future appeared on both color aerial photographs for the future use.
