GIS can be defined as a computer system designed for storing, manipulating, analyzing, and displaying data in a geographic context. One of the advantages GIS provides is the ability to assist in the decision making process by providing an additional tool to analyze and compare numerous geographic data layers along with traditional databases.


Yellowstone County's Interactive Mapping websites are sites that allow you to access the County's GIS data interactively and quickly over the Internet. These sites allow the user to view various data layers, see tabular information related to the layers, and print maps. Users can select by property information such as owner name, address, legal descripton, parcel identification number or geographic extent. Links to assessment, property tax and jurisdictional information are also provided.
