One of the major problems involved in surveying vegetation cover in urban areas using satellite images is that there are many areas of vegetation which are smaller in size than the resolution of satellite data. By overlaying satellite images with corresponding vegetation maps, we examined the relationship between vegetation cover ratio and vegetation index pixel by pixel. It was found that as the vegetation cover ratio decreases, the difference between it and the vegetation index becomes increasingly more significant. Based on the average vegetation index, we estimated the area of vegetation and found that this method was more accurate than the more widely used method of supervised classification for estimating vegetation areas. This was because our method is capable of estimating areas in proportion to the mix of vegetation cover, that is, it is more suitable for estimation of actual vegetation cover in urban areas.
