September 9, 2025. The Visual Data Analysis (VDA) Geographic Information System (GIS) is a computer-based tool that allows users to store, analyze, visualize, and interpret geographic data. VDA GIS tools are structured for online (VDAW4/iVDA) and offline (VDAD) use and operation with Windows, Mac and iPhone devices. This section provides basic information regarding VDAW4 and iVDA. These tools may be used with user projects or VDA Projects. See available projects at this main project list. This document is provides a summary of basic VDAW4/iVDA usage.

Complete the following steps using VDAW4. You will be able to display median age by county (a label) and median age by county (a label) from the ACS 2023 county file (item D018). Userfile download First, select the project where the layer is located. e.g., Population County -- Age/Gender With a project open, select a layer making it the active lauer (left click name) Click the Userfile download. A form appears. Click the Make Shapefile. The name of the shapefile is shown; it will not be familiar and is assigned by the system. Click the Download button; the downloaded file will be in a folder on your computer. The shapefile correponding to that layer has been downloaded. Close the Userfile download frame. Userfile upload First, select the project where the layer is to be added e.g. American Community Survey 2023 County Data Profiles. Click the Userfile upload. A form appears. Click the Choose file. The name of the shapefile is shown; assigned by the system. Select the shapefile to be added. This name is a ZIP file and was stored on your computer. A new layer is added at the top of the Legend Panel corresponding to the shapefile. Close the Userfile upload form. The map window shows the shapefile as the top layer. It has a gray fill pattern. Optionally modify the layer attributes with the Tools>Layer Editor. Add a label (medage as upper, center) Optionally move the new layer down with the up/down feature. Save Project Click the Save button to save the project e.g. while American Community Survey 2023 County Data Profiles with new layer is opened. The original project will not be affected. Open Project Any authorized user can now open the new project. The new project name is not promoted or listed. To Open the project with the added layer, click Opem Project. a form opens showing the projects saved using this method. the most recent project saved is shown at top. Displaying and interpreting the differences in ages. Why is there a difference in the two median ages diaplayed? 1) the ACS 2023 data are 5-year estimates based on a survey (the latest) -- centric to 2021 2) the data from the 2024 median age by county are two years more recent and based on model-based estimates. ACS 2023 data are 5-year estimates based on a survey (the latest) -- centric to 2021 .. zoom in to Kansas counties .. click graphic for larger view  .. Sedgwick County (Wichita) .. median age 35.9 years (statistical survey with MOE known) 2024 median age by county are two years more recent and based on model-based estimates .. click graphic for larger view  .. zoom in to Kansas counties .. Sedgwick County (Wichita) .. median age 36.4 years (model-based, no MOE available) Database .. goto top Database includes Windows applications listed below. Without setting up your computer to use these applications, they will not operate. Each Windows application requires a registry entry. At this time, these applications work on/use only local data files. More on this later. Make a unique directory, for example c:\VDAGIS1, that will be used to house the applications and related data. 1. County Projections Explorer (CPE) Expand the CPE file to c:\VDAGIS1 2. dBTools Expand the DBTools file to c:\VDAGIS1. 3. ChartGraphics Expand the ChartGraphics file to c:\VDAGIS1. 4. Expand this zip file (registry bats) to c:\VDAGIS1. To launch a Windows .exe file from a web browser, you must register it in the registry of your computer. The above zip contains batch files to automate this process. addreg.bat delreg.bat 5. From that same folder, run (from command prompt in c:\vdagis1) addreg [application name]. Examples: If the application is cpe.exe, run addreg cpe .. if dBTools.exe, run addreg dBTools .. if Chartgraphics.exe, run addreg ChartGraphics Click OK or YES to the message dialog. If you want to remove the registry entry created, run the following command from an elevated (Administrator) Command Prompt: delreg [application name] Example: delreg cpe You should now be able to see/use the Windows applications from iVDA. Remember that the files used are local to your computer.

Proceed as follows. Use the above iVDA tool and project. Make the County Annual Population the Active Layer Click the Table/Query button In the SQL Field, enter "st='20'" (omit quotes) .. the variable "st" contains the text-based state FIPS Code Click Query button. Table refreshes with 105 Kansas records. Part 2. Click the top (any) record in the Table. Next click the "Map 1 Selected" button. The Map Window zooms to that area.
