D. Validation with in-situ data
Validation with in-situ data is important to ensure the predicted location in the real world exists. From the in-situ investigation, there is only one place that had been identified to have Solar Photovoltaic panel. Two other places that have existing PV system installed at Georgetown area were used to validate the suitability map. The address and coordinates of the two points are as following: • 539 Jalan Masjid Negeri, Georgetown ( 5° 23’14.94 N, 100° 18’16.03”E) • 2.26, Wisma MTT, Georgetown (5°24’51.69”N ,100° 20’28.64”E)
These were 30 pieces of solar PV panel that had been installed at Wisma MTT, Georgetown (Figure 9) agree with the 30 solar PV panels calculated using GIS modeler in ArcGIS 9.3.
