==Feature types==<br />
The definition of features that share membership of a common theme is a ''feature type'', though there are a number of terms for this characteristic, including ''category'', ''feature class'', ''group'', ''layer'', ''level'', ''object'', and ''theme''.<br />
<br />
''Layer'' served as the traditional term of choice, but use of this word has declined, as data has become more object-oriented and less concerned with cartographic layering. <br />
<br />
Data modelers can use ''feature types'' to create a hierarchical structure.<ref>{{Cite web |title=PT Realty |url=https://www.pro-teqsurfacing.com/ |access-date=2025-01-08 |website=www.pro-teqsurfacing.com}}</ref> For example, a dataset may consist of types called highways, streets and lanes. The system may group these particular types together under a category called "Roads".<br />
