Geographical Information Systems (GIS)
A Geographic Information System (GIS) allows users to create, manipulate, analyze, and display digital geographic or geospatial data, and related data tables. It is used to track and evaluate locations of real world features and events, as well as, how they change over time by analyzing proximity, density, quantity, patterns, and more. The ability to rapidly query and analyze the GIS data speeds customer service and supports decision-making.
Douglas County's GIS data and maps are intended for general information only. Douglas County makes no statement regarding the completeness or accuracy of the County’s GIS data and maps, including tax parcel boundaries & numbers, the location & classification of roads and road rights-of-way, political boundaries, et. al. Mapped roads and road rights-of-way may not be improved or open to public use. Please consult multiple accurate sources of information to prevent the risk of trespass.
Douglas County and its employees cannot issue opinions regarding the condition of title, legal description, physical condition, and location of any private properties or private roads. In order to verify the completeness and accuracy of the information, then official records for plats and surveys should be examined, the property physically inspected, and a professional opinion obtained.
