1. What is AIMS?

AIMS stands for Automated Information Mapping System and is a department within Johnson County government. AIMS is a Geographic Information System, or GIS. A GIS is a computerized system for managing large amounts of information that is geographically referenced or related to a location. In other words, a GIS is smart maps. An integrated GIS is generally a "turnkey" system operating on a computer system in a client/server environment. It often has plotter, digitizer, or color printer devices attached to the computer or on the network. The GIS also includes software for graphic processing, database management, and spatial analysis and modeling. The AIMS database integrates graphic and nongraphic data. Return to the top

2. How does GIS help me?

By combining locational information with tabular information, GIS provides users the ability to make very informed decisions with improved efficiency at less cost. AIMS enhances this ability by making the county’s maps and data available online. GIS is used in many arenas including emergency management and response, property appraisal, public works, health services, and economic development. Return to the top

15. How current is the map data on your website?

This question is most often related to planimetric, aerial, and property data. Planimetric data was collected over the years of 1998, 1999, 2000 and 2004. Some features (e.g. buildings, pavement edge, water features) have since been updated every two years in coordination with aerial imagery capture. To inquire for specific dates for your area, please contact the Aerial data is current for the year it was flown. Orthophotography is captured in the spring of even years and release in the late summer or fall of that year. Property information is typically updated within two weeks of a change requested by the Department of Records and Tax Administration. Return to the top

16. How accurate is the map data on your website?

This question is most often related to planimetric, aerial, and property data. Planimetric data is accurate depending on the year acquired (See Question #15) to within 2 feet. Aerial and orthophotography accuracy is dependent on the year. Resolutions range from 2 feet pixel to .5 feet pixels. Property data is also accurate to within 10 feet. Property data should be used for planning purposes only and a survey should be conducted to locate the actual physical property lines. You can search for Johnson County surveyors here. AIMS has no control over the accuracy, currency, or completeness of publicly available basemaps provided by Google, Bing, and ESRI that we overlay our data with. Please view the associated metadata for all accuracy information. Return to the top

17. How do I report map errors in Online Mapping?

AIMS often receives questions regarding errors related to street names, business locations, and GPS routing. Here are some quick tips to help you report possible mapping errors. If the Base Map within Online Mapping (upper right corner) is set to ‘JoCo Map’, then you are viewing Johnson County data. Please report any errors to addressinfo@jocogov.org and AIMS staff will work with the appropriate parties to make sure the error is fixed. If the Base Map is not set to ‘JoCo Map’, then you are viewing a private company’s data.

18. Why can’t I get the property ID or other labels to show up on the map I print from the Johnson County Online Mapping application?

Property labels are only available at certain scales due to the complexity of sending large amounts of data across the internet. Zoom in more to get the option to label the property. The property polygon must also be checked for drawing. If you need a map of a larger area with labels contact the Mapper of the Day (913-715-1600) to get an estimate. Return to the top

19. How can I get the X,Y (latitude, longitude) of my property?

You can receive the X, Y of the centroid of your property or of a corner of the property by going to Johnson County Online Mapping and zooming to your parcel of interest. Then hover the cursor over the point of interest and in the lower left corner of the browser status bar the stateplane coordinate will be displayed. This unit is in feet. Using freeware off of the internet or commercial packages you can convert it to Latitude and Longitude if necessary. Return to the top
