Continued improvements on the BrownDog app

The "BrownDog" online GIS app continues to be developed.  This app will work on any computer device, including iPhones and iPad.  BrownDog is an alternative for those who cannot use our older GeoPrime flex app.

Some of the latest enhancements to the BrownDog online app include:
  • Search by Land Owner Name (available through the Advanced Search button).  This type of search requires a password which is available through the registration form link at the top of the app. 
  • Other enhanced search capabilities using the basic search box and the advanced search button.
  • More map layers and more control over the layer display.  For example, click the ... (ellipses) to the right of the layer name to adjust layer transparency. 
  • Better popup window displays.
 In the coming year, more enhancements to the online GIS sites are planned.


New Brown County map includes 2016 population estimates, land cover

A new Brown County map was recently published as a downloadable PDF:
This map includes major roads and municipal boundaries as well as 2016 population estimates for each municipality.  General land cover classifications show developed, agricultural and forest lands colored in green & gold (of course!).  Land cover is based on the Wiscland2 dataset.  As a final touch:  A 'hillshade' effect was lightly applied to show topographic relief.

Here is a preview of what you'll get when you download the PDFs:



Changes Coming to Brown County's Land Information Web Sites

Some news regarding Brown County's land information web sites:
  • The Property Search site will be getting an overhaul in 2017.  Our Property Search site has changed little since it launched about 15 years ago, but the time has come for change.  This site runs on tables stored in a 33-year-old AS/400 system which is slated for replacement in the coming year, and with that, the Property Search web site will also see some changes.   The new site will have the same information as the old (possibly more) and will of course link to the new GIS site for the map.   More details to come.
  • GeoPrime will be replaced:  Although GeoPrime is Brown County's most-used GIS web mapping site, it has to be phased out  because the technology it is based on is no longer being supported.  GeoPrime will likely be shut down completely by 2018.
  • Plans for the new GIS mapping websites:
    • A new "basic" GIS site will be launched in the coming months.  Check back for the link when it becomes available.  This new site will have mostly the same functions and simple 'look and feel' that GeoPrime has.  Some of the benefits of the new site include:  It will have much faster performance;  It will have 'responsive design' meaning it will work well on any web or mobile device including iPhones; Buttons and the map view will adapt to the screen size;  It will use the Javascript API, which won't require 'plugins' to run ( just know it will make your IT security people happy!). 
    • A new "advanced" GIS site is also being developed.  This site is not finished, but it is available now;   Click here to check it out.  For lack of a better name, we are calling it the "BrownDog". Why BrownDog, you ask?   Well, 1) because we couldn't come up with a better name that has anything to do with Brown County that wasn't boring and 2) because we like dogs (that is a photo of Sunny, my Golden Retriever on the thumbnail image. She's not quite brown in color but close enough and definitely cute enough, I think!).  The advanced site will use the same technology and base data as the basic viewer, but it will have many more functions & features to keep the tech-savvy people happy.  Like the Survey Index, this app is based on Esri's Web Appbuilder which makes it easy to add new features.
    • The above sites are designed for multiple purposes & general GIS use.  As you probably know, we also offer other more 'focused' maps and apps including:

Online GIS map update schedule

Map Update Schedules

How often is the online GIS map updated?
A GIS is comprised of map layers & information from many different sources.   A common question we receive is:  How often are the individual map layers updated?     Here are some general update schedules:
Base Map layers
  • Our “Standard Base Map” is updated weekly.  This default base map includes many layers including roads, parks, schools, parcel outlines, addresses, and other information.   The map updates run weekly but there are some caveats:
    • Address numbers are assigned by the municipality (not the county) in most cases.  The County makes every effort to collect addressing information from
      each municipality so that information is up-to-date.  Every address in the county should be in our system.  If you find any that are missing, please contact the Land Information Office at 920-448-6295 and we will work with the addressing administrator to update the county address database.
    • Building outlines (building ‘footprints’) are NOT complete county wide. Building outlines are mapped by the municipality on an irregular schedule;  The County will collect and building outlines as they become available from these other organizations.   Note that in most cases, we will have the address number up-to-date in our system, but the building outline may not be mapped graphically because the address map layer is separate from the building outline map layer.  
  • Most of the aerial photo base maps are named with the year taken (for example, Aerials-Summer 1938).  In years past there has been no consistent schedule as far as when flights were completed, although since 2000 we have been collecting photos at least every 5 years.   
    • In the future, we hope to collect new aerial photos every 3 years.  Our most recent flight was this year (2017) and if budgets allow our next flights will be in Spring 2020.
  • The “Landscape” base map shows terrain with a hillshade effect.  This was created using topographic data shot from the 2010 LiDAR flight (same source as the 2010 contour overlay).  We hope to obtain new LiDAR data in 2020 or sooner.

Overlay Map Layers
The overlay layers are updated approximately on the following schedule:

    Municipal Boundaries:  Updated as needed (annexations, etc are generally put into the GIS within a week of the time they are recorded by the Register of Deeds)
  • Airport Zoning:   As needed (very infrequenly)
  • POWTS (Private Onsite Waste Treatment Systems) are updated approximately weekly
  • Flood Mapping is updated on FEMA’s schedule (which is very infrequent; last countywide update was in 2009).  However:
    • We do  track changes known as “LOMAs or LOMRs”  (Letters of Map Amendment and Letters of Map Revision).    These changed areas show as red outlined areas in our Flood Mapping layer.  We will update these as often as we receive the information from FEMA.   Use the “Identify Drilldown” tool, click on the map, click the “LOMA/LOMR” from the list and then you can view the date the LOMA or LOMR was approved and view the associated PDF maps and letter from FEMA.
  • PLSS (Public Land Survey System) section lines, section corners, forty lines, etc:   Updated as needed.  Corner tie sheets (PDFs available using Identify Drilldown) are input by our County Surveyor as they are updated.
  • Districts & Wards:  Updated soon after redistricting is completed every 10 years (last redistricting process was in 2011).
  • Schools/School Districts:   Updated as needed
  • Parks:  Updated as needed
  • Outdoor Warning Sirens:  Updated as needed
  • Addresses:  Address numbers should be no more than one week old (see Base Map information above)
  • Parcels:  Updated daily, though there may be some delays from the time the document is recorded by the Register of Deeds to the time the map is updated.
  • Parcel Ownership:   Updated daily, same as above
  • Survey Index:   Not complete in the City of Green Bay;   updates are being put in as time permits
  • Transportation:  Roads, railroads, etc are updated as needed.  We will generally show “proposed” streets as soon as plats are recorded by the Register of Deeds, and then we will change them from “Proposed” as they are built, when we are made aware that construction is complete.
  • Elevation Contours have a date on them.  The 2010 contours were produced using our April 2010 LiDAR flight.  We hope to do another LiDAR flight (which will produce contours) by 2020 or sooner if budgets allow.
  • Wetlands:   The DNR WWI (Wisconsin Wetland Inventory) map layer is maintained by the Wisconsin DNR.   The County will collect updated data and update this map layer whenever we are aware of changes.
  • Lakes & Rivers:   Updated as needed
  • ESAs & Shoreland Zones:  Updated as needed
  • Soils:  This map layer is maintained by the USDA Natural Resources Conservation Service (NRCS).  The County will collect this data from the NRCS and update this map layer whenever we are aware of changes.


Land Owned by the Green Bay Packers

Parcels of land owned by the Green Bay Packers

Click to view interactive map
How to use the interactive map:
  • Zoom in (tip: Use your mouse wheel to zoom in / out)
  • Click on each parcel to view more details (assessed values, acreage, links to other real estate documents, and more).  You can view this information for adjacent parcels as well. Assessment values are the most current available at Brown County; Assessment values are updated each spring/summer via the municipal assessor.
  • Click Layers (blue button to the upper left of the map)  to interactively view this area with older aerial photography and historic parcel data. This will allow you to view the development of this area from 1938-present and see how land ownership has changed.
More interesting facts about this area:
  • The parcel on which Lambeau Field is located is not owned by the Packers (it is owned by the City of Green Bay).
  • Most of the highlighted parcels west of Lambeau Field will become part of the Titletown District development starting in 2016.  The Titletown District is in Ashwaubenon.
  • Many of the smaller parcels south of the stadium were converted from residential lots to parking lots over the last 5 years.
