16 impact to the conservation areas, such as population density, household forest
activities and traditional forests land claim by community. Traditional forest land claim map is generated by assessing the traditional boundary in the field, using
GPS device. This data layer provided information like distribution of Ratu Forest Claim in national park that must be taking into account when making a
management decision. Even this right is not recognized yet under government low, but considering the aims of establishment of the national park is to conserve
the community rights of land. Results of data preparation are described followed.
3.4.1 Terrain Model
Terrains model such slope and elevation generated using height points derived from USGS SRTM. First process is to crops the points of area of interest.
This done using Global Mapper Program thence exported as text file with spatial resolution has resample the original resolution from 90 m x 90 m. Height point
data X, Y, and Z that has geo-referenced thence interpolate to produce Triangular Irregular Network TIN as raster dataset to generate elevation and
slope map. The use of height points data are given are smooth result in surfaces analysis but its less accurate at coast area.
Slopes classes derived from GTOPO30 data EROS Data Centre, 1998 the Global Agro-Ecological Zones Study, Food and Agriculture Organization of
the United Nations FAO, Land and Water Development Division AGL with the collaboration of the International Institute for Applied Systems Analysis
IIASA, 2000. Surfaces data analysis resulted about 88.19 of terrestrial park are flat
slopes 8 and 11.81 other are with slope hilly to mountainous slopes 8. In table 4, showed the percentage of area based on slopes class in Nino Konis
Santana National Park.

17 Surfaces data analysis also produced elevation map for study area, as list
in table 5 that the area is almost 94 dominated with elevation range between 0-500 meters, while areas above 500 meters to 925 meters only 6. Elevation
Map has indicated that within area of study are less than 2000 m. The highest point only 925 m and its meaning no area fit to the HCVA 1.1 protected places
with elevation 2000 m.
