What are the two types of MAUP?

The two types of the Modifiable Areal Unit Problem (MAUP) are indeed the Zone Effect and the Scale Effect. The Zone Effect refers to the way the results of analysis can change based on the specific zones or areas into which data is aggregated. When data is categorized into different spatial units, the configuration of these units can influence the statistical results.

The Scale Effect pertains to how the results can vary when the scale of analysis changes. For example, aggregating data at a larger geographic scale may result in the loss of local variations and nuances that would be visible at a smaller scale. These aspects highlight the importance of careful consideration when selecting spatial units for analysis in GIS, as they can significantly impact the conclusions drawn from the data.

The other choices propose different potential effects, but they do not correspond to the established classifications of MAUP. Understanding the Zone Effect and the Scale Effect helps GIS professionals to critically assess their analyses and avoid misinterpretations that may arise from inappropriate aggregations or scales.
