Remote Sensing and (GIS) applications in the Erosion studies at the Romero river Watershed
Results and Discussions
Figure 1. Topgraphic map of the watershed
Figure 1 present the Topographic map of the project area. The map looked as if it is manually mosaicked , cut and scanned. This was not the case, however. As explained in the Material and methods .The map is georeferenced, digitized and saved as vector geospatial data .
Figure 2. Land use map of the watershed.
Figure 2 showed the Land Use Map. Coconut and grasses are is the dominant land uses followed by forest .The other land uses are grasses and paddy rice.
Figure 3.Soil map of the watershed.
Figure 3 is the soil map. Sampaloc series , slightly eroded is the dominant soil types in the upland area. For the low lands, the major soil are Coralan, Halayhayin , and Baybay series.
Figure 4 . Slope map of the watershed.
Figure 4 is the Slope Map. The lowlands are generally level (0-3% slope ). The sloping to undulating uplands have slopes of 3-18%. The complex mountain range that traverse the area has slopes of over 18%
Figure 5.Landsat image of the watershed.
Figure 5 is the landsat Image of the watershed taken on Aril 2, 1993.
Figure 6. Land cover interpretation map based on landsat.
Figure 6 is the Land cover Interpretation Map of the Landsat image using the supervised classification function of TNTmips. The land cover map based on satellite image showed that coconut and grasses are the dominant vegetation in the area.
