The main objectives for site selection as follows:

• Land use for project site and surrounding area.
• Distances from the populated area, local community, existing access or road, existing transmission line and etc.
• Environmental and geospatial conditions around the site such as existing slope, shadows, average temperature, humidity and etc.

GIS for site selection has many advantages. We can classify the advantages in the scope of Economic, Environmental and Operational Efficiencies.

• Using GIS to analyze proximity of solar farm to consumers. Electricity and distribution losses has direct relation with distances to consumers. Ideally its better to build power stations near to residential area or power lines.
• Lastly, reducing civil construction cost by selecting the most suitable site.

• Input of geospatial data can be use in GIS application for data analysis in Environmental Impact Studies. As an example, aerial mapping will provide current imagery of the site conditions.
• Various other spatial data can also be extracted from aerial images using suitable sensors available such as multispectral, infra red etc. This information can be used to provide valuable input for the environmental impacts studies.

Optimizing geospatial data for selection of solar farm site location. GIS data can be easily integrated and performed analytical studies based of topography, temperature, precipitation , humidity ,etc.
