If a geographer wanted to use a geographic information system (GIS)to study soil contamination and determined that only the areas within 1.5 kilometers of a toxic waste dump needed to be considered and mapped, he/she would be most likely to choose which type of GIS function?

Buffering allows the geographer to create a specific distance around a point, such as the toxic waste dump, and analyze only the areas within that distance. This would allow the geographer to focus their analysis on the areas most likely to be impacted by soil contamination. Kriging is a spatial interpolation technique used to estimate values between known data points and is not directly relevant to this particular analysis. Area calculation and point-pattern analysis may be useful in other analyses, but are not directly relevant to the task of mapping soil contamination around a toxic waste dump.
