What is GIS?

A Geographic Information System (GIS) is a mapping infrastructure that links the location of a map feature with textual data of that feature. Unlike a paper map, where “what you see is what you get,” a GIS combines many layers of features, creating a dynamic mapping environment. The GIS environment gives you the ability to view and query the map based on the contents of the database.

What online services do we provide?

Currently we provide an interactive mapping application that displays property information collected by the Auditor’s Office. In addition, information on surveys completed within the county and county controlled zoning are available from this site.


The “GIS Hub” is the platform for exploring and downloading Clark County GIS data, discovering apps, and engaging others to solve important issues. You can analyze and combine datasets using maps, as well as develop new web and mobile applications. Let’s achieve our goals together!
