Which system is used to identify the proximity of parcels to features that may affect their value?

The Geographic Information System (GIS) is the correct choice for identifying the proximity of parcels to various features that may influence their value. GIS is a powerful tool that allows for the storage, analysis, and visualization of spatial data. By mapping out features such as schools, parks, commercial areas, and transportation networks, GIS helps assess how these elements can impact real estate values. The proximity to desirable amenities or potential nuisances can significantly affect property values, and GIS provides the necessary geographic context to analyze these relationships effectively.

Other options do not serve this specific function. An amortization schedule is a financial tool used to outline loan repayment details over time, while contingency tables and cross tabulation are statistical methods for analyzing the relationship between categorical variables, rather than focusing on spatial relationships and their economic impacts. Thus, GIS stands out as the most relevant system for assessing the influence of location-related features on property value.
