Ground check: 5. RESEARCH QUESTION: Is there
plantation in forest zone?
• To get physical evidence on GIS result, we could use GPS.
• Enter the coordinate of deforestation area into GPS.
Minimum data required:
• Use GPS to navigate us to the determined area.
• Spatial data of forest zone.
• After arriving at the area, prepare the report.
• Spatial data of land coverage.
• Spatial data of plantation area.
4. RESEARCH QUESTION: Is there land
overlapping and inappropriate land utilization?
Data analysis:
Minimum data required: • Intersect spatial data of coverage area at the beginning of
the year with data taken from the end of the year, to obtain

• Select area where there is overlapping land use.
Ground check:
• To get physical evidence on GIS result, we could use GPS.
The result can be seen in the following figure:
• Enter the coordinate of plantation area inside the protected
forest into GPS.

• After arriving at the area, prepare the report.

Plantation on forest zone

From the Figure 5, it can be seen that overlapping has
occurred between farm area and LFC, and, after referring to
the database, the overlapping was found to occurred in the LIMITATIONS OF GIS
