In addition to Landsat images, Google Earth images have been captured with high resolution. Coverage within each image was minimized during capturing to ensure high resolution images. Five images were captured and geo-referenced to cover the study area. Figure 3 shows sample of mosaic Google Earth images with 3.0 m ground resolution. This resolution would allow for accurate digitizing of linear features as described in the following section.
