Douglas County has been collecting digital data since the late 1980's. Our main goal in the beginning was to automate the assessment mapping and achieve a streamlined process for updating and sharing a common base. Then the work began...

We first developed a PLSS base and a land ownership dataset that was tied to the State Plane NAD27 coordinate system. All other information was built on this data set. Later the map was shifted to a State Plane NAD83 coordinate base as a whole with no adjustments. 

You will notice that not everything will line up exactly due to the process of years of collecting data from different sources at different reliability factors. This website is a work in progress which will improve as new or better information is made available

The use of new technology has given us the ability to distribute information to the public in a visual manner. This is our goal ! 


 The content of the website is organized into maps for different types of research. 

     Base Map - Locating the area of interest, assessment info, ownership, surveys
     Control - Find Vertical and Horizontal control points
     Gov Corners - Search for cadastral information

Basic ideas to remember:

          - All actions on the website are performed by a click, click procedure. There is no click and drag.

    -   All toolbars available at the top of the screen have a description of use in the help. The first time you enter this website you may want to browse the help to get a feel for how the website works and what each tool does.

    -  When selecting a feature on the map, there is a top down process that gives detail information. This can be changed by using the legend properties tool.  This may require a refresh. 

    - You should start with the binoculars to search using predefined queries that are designed for the type of data included in each map.  Enter your information following the example and hit find.

  - When a query results in multiple choices, use the push pin to select the desired result. The pushpin at the top will select all. Pushing the pin again will unselect the item.

       - When using the address search, be patient. The drop down is organizing every street in Douglas County by alphabetical order.
