Green Bay and Brown County Wisconsin through 72 years of change

The app will show you two aerial photos side-by-side with an interactive vertical bar down the center.    The aerial photo on the right is from 1938 and is the earliest complete aerial photo ever taken of Brown County.  

Drag the vertical bar left & right to compare aerial photos from 1938 to 2010.  Zoom in on the map to see the details.  (tip:  zooming with your mouse scroll wheel is often easier than using the + and - zoom buttons on the app).

Explore the growth of the cities and other changes to the county's land use over 72 years with this map.

Note: When zoomed in, modern-day streets and properties will appear to help provide you with some reference.


Using the Draw tools to add your own graphics to your GIS map

You can draw your own map graphics on the GeoPrime app.  Draw lines, text or areas to highlight things on your map and call attention to them.  Here's how:

1) In the GeoPrime app click the "Tools" button  > Choose "Draw"
2) Pick the type of feature you'd like to draw (point, line, box, circle, polygon or text)
3) Choose options like color and line thickness, then start clicking on the map to draw.

To move a graphic after it's drawn, click on it to 'select' it, then drag the graphic to move it.

You can save your graphic drawing by clicking the "save" button on the lower right portion of the Draw toolbox.  This will save a file to your computer with a ".drw" file extension.   You can always load that .drw file back into your map using the "load layer" button on the far lower right corner of the Draw toolbox.  
*Note that this process will save the graphic drawing overlay only, not the entire map (to save the entire map with your graphic overlay, you should instead use Print > Save PDF or Save Image).

Saving these .drw files is also useful if you need to switch to other tools and you want to preserve your graphic drawings. You may have to load your graphics back in if you move on to another tool.

Here is an screen shot showing an example of some extra graphics added to the map with the Draw tools:

Accessing the "Map Key" (map symbol legend) in the GeoPrime app

 The GeoPrime mapping site provides you with a lot of useful information about properties in Brown County.  The map uses lots of map layers with many colors and symbols, and although we strive to keep the map as user-friendly as possible, the groundswell of information can be a bit overwhelming at times.

To help understand what the map symbols mean, one handy shortcut is to click on the layer name.  This will bring up a map key (legend) for that particular map layer or layer group. 

For example, clicking on the name of the layer "ESAs & Shoreland Zones" will show you the various symbols associated with the ESA layer and some other information about it as shown on the screen shot below:

There is also a printable legend (PDF) available on the app's upper toolbar.

Note:  This screen shot/example shows the Shoreland Zoning and ESA (Environmentally Sensitive Area) map layers--If you have more questions about these, click here.


How to zoom quickly on an online map using the Shift key

Brown County online GIS

“Zoom In” quickly using the Shift key

How to Zoom In to an area (handy shortcut using your Shift key)
The GeoPrime web map and most of our Featured Maps & Apps  allow you to zoom in to a rectangle that you draw.  This shortcut will help you zoom around the map more quickly and it’s very handy when starting from a wide view, such as the entire county, and zooming in to a specific location.

Here’s how to do this:

  1. Press and Hold Down your “SHIFT” key

  1. While holding the SHIFT key, use the mouse’s left click button and drag a box/rectangle on the map.

The rectangle/box that you draw will show as a red outline.  
Simply release the mouse button (and shift key) when you have finished drawing the box around the area you want to zoom to and the map will go to that location.

Your mouse scroll wheel will also allow you to zoom in/out, as do the buttons along the left side of the map.  
And of course if you know the address, street, or parcel number you wish to zoom to, you can use the “Search” button to quickly go to specific locations.
