# Filter vector data Filtering allows you to display a subset of features within a vector layer based on attribute values. This is useful for focusing on relevant data, reducing visual complexity, and analysing specific conditions within a dataset. A short video walkthrough is available below. {% embed url="" %} *** #### Applying filters Filters are applied to a vector layer based on feature attributes. You can define conditions to include or exclude features from the current view. Typical use cases include: * displaying features within a specific value range * isolating specific categories * focusing on features that meet defined conditions *** #### How filtering works Filtering does not modify the underlying dataset. It only affects how data is displayed in the viewer. Multiple filters can be combined to refine the visible subset of data. *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ellipsis-drive.com/working-with-vector-data/filter-vector-data.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
