Updating of land-cover maps by using texture information from very high-resolution space-borne imagery

Funded under: FP5

Abstract

The process of updating existing land-cover databases is an issue of great concern for keeping existing and often expensive information valuable. Often, this problem is one of integrating appropriately multi-temporal data sets that are completely different in nature. In this article, a methodology is proposed for the updating of land-cover databases by using texture information derived from very high-resolution panchromatic space-borne imagery. At a given scale the homogeneity of texture derived from newly acquired imagery is measured within the polygons to update by means of knowledge-based segmentation approach. In a successive step, the new region contours are compared with the existing polygons. This basically transforms the change detection problem into one of image segmentation. Experimental results for the analysis of urban-rural relationships by IRS-1C panchromatic imagery indicate the usefulness of the taken direction.
