this research is based on the small study area, and according to the river networking. In this research, only big river was analyzed.
By the same procedure with to extract contour, attribute data of buffered river have to be assigned data by location spatial join to
included in PVC attribute data, and the result can be seen in Figure 4.11.

The result of assigning data by location spatial join of river
buffer LogR_Riv 1,000 m, where yellow cells is river or group of river 1,000 m 1 and light blue is
≥ 1,000 m 0.
4.2.4. Data Extracting of Road Buffer Process
Basically processing to extract road buffer and put into polygon vector cell PVC is similar with extract river buffer data
process. Actually data type of road is line and road networking may be
quite dense. Because of each road features are buffered 1,000 meters, all read network possible to become one feature, road buffered area.
Since in this study area is totally protected area where there are no road allowed exist, and this study area just using subdistrict street; so
44
Figure 4.16 can show existing road buffered area is only a small area in the east part of the study area.
Value 0 of LogR_Road is for inside area of buffered road and
1 is for the outside area. Inside buffered road also is identified as non-road Net. Next process is geoprocessing and assign data by
location for spatial join to PVC attribute data table.

4.2.5. Data Extracting of Shoreline Area Process.
It has obtained a polygon boundary of study area before. This polygon could be created from village administration data from
BPS Badan Pusat Statistic-Bureau of Statistical Center, and query builder process to produce one polygon of study area boundary.
The boundary polygon shapefile, have to converted from polygon to polyline, and the polyline will be split to get the shore
line only . The polyline attribute must be edited, by adding 45
LogR_SL logistic Regression of Shoreline. LogR_SL will be
valued 0 for inside area of buffering and 1 for outside area Figure 4.13.
Shore line was buffered also 1,000 meters towards inside the land, there is no deal with the area toward the sea.
