In a land use survey, if you are analyzing spatial distribution, what is needed?

• A. A base map and an appropriate key
• B. A larger sample size
• C. A computer with GIS
• D. A climate data set

Answer: (A)

To show how land use is spread across space, you need a geographic reference and a way to read what you see. A base map provides the locations and boundaries to plot the different areas, and an appropriate key (legend) explains which land-use categories each color or symbol represents. With those two, you can identify patterns like clustering, gaps, or corridors in the distribution. A larger sample size helps accuracy, but it doesn’t establish the spatial framework by itself. A computer with GIS can make analysis easier, but the essential requirement for mapping spatial distribution is simply a base map plus a clear key. A climate data set isn’t relevant to identifying how land use is distributed across the area.
