Abstract

The confident level on the analysis and evaluation results is highly dependent on the accuracy of data interpretation. This study aimed to evaluate the capability and accuracy level of image interpretation ALOS AVNIR-2 in the mapping of land in the Watershed Moramo, Moramo District, South Konawe. The research was conducted on the interpretation results of land unit element of the pre-processing to image processing. Interpretation of land units performed by the analytical approach of landform, lithology, slope, and land use through the  introduction of  the  basic  elements of  visual  images by  means  of  on-screen digitizing. The result showed that the image of ALOS AVNIR-2 composite image processing through 341, sharpening the contrast and spatial filtering can provide information in identifying land units in soil mapping with very clear to clear. Accuracy of 89.06 % landform unit; lithology of 92.19 %; and land use mapping by 90.63 % and 90.00 % of the land, or an average accuracy of interpretation of land units in providing information for mapping land located in either category (>85 %). Keywords :   ALOS AVNIR-2 imagery, image processing and interpretation, watershed, land evaluation unit, the mapping
