When using GIS for site selection, which data layers are typically considered?

• A. Weather patterns only.
• B. No data needed.
• C. Population distribution and accessibility.
• D. Random guess.

Answer: (C)

When you use GIS for site selection, you combine multiple spatial data layers to evaluate how well different locations meet key needs. Population distribution helps you estimate market size, labor pool, and potential customers, while accessibility assesses how easy it is for people to reach the site and for goods and services to move in and out. Together, these layers show where demand is strongest and where logistics are most efficient, which is central to choosing a site. Weather patterns can matter for certain types of sites, but on its own they don’t provide the full picture of market reach and logistics. Not needing any data goes against how GIS works, since the analysis relies on comparing real, spatial information. A random guess ignores the data-driven approach that GIS enables.
