There is not any shortcut to fixing the inexpensive housing disaster within the U.S., however figuring out a logical method to current housing information is a crucial first step.
Geographic info system (GIS) software program groups from town of Philadelphia and the Frontier Institute in Montana lately spoke with InformationWeek about how they’re mapping out group information to color a clearer image of the components contributing to the housing disaster. By designing interactive maps and digital dashboards utilizing GIS firm Esri’s software program, Montana and Philly have been in a position to transfer the needle on the inexpensive housing disaster.
Half one in every of this sequence focuses on how mapping out the upcoming sprawl of main hubs in Montana led to regulatory adjustments. Keep tuned for half two, which focuses on inexpensive housing challenges in Philadelphia.
How GIS mapping modified the housing debate in Montana
In Bozeman, Montana, native officers had been skeptical that regulatory reform could possibly be an efficient method to tackle the rising value of housing, stated Kendall Cotton, CEO of the Frontier Institute, a suppose tank primarily based in Helena. To visually clarify the potential impression of regulatory adjustments on the housing disaster, Cotton and his staff determined to create the Montana Zoning Atlas. The interactive GIS map lets public officers and residents entry a visible illustration of Montana’s housing information.

“Our objective was to principally clearly reveal how strict native zoning laws are making it troublesome to construct the houses we have to construct to maintain up with demand,” Cotton stated. “We ended up principally making a profile for every main metropolis in Montana.”
Utilizing Esri’s ArcGIS software program, the Frontier Institute staff was in a position to create color-coded maps displaying information “down into the parcel stage,” Cotton stated. With the atlas, Cotton’s staff may visually reveal that present laws had been limiting the varieties of houses that could possibly be constructed on land parcels. Below present laws, single-family dwelling builds had been outpacing multi-family dwellings.
The atlas additionally helped reveal “how laws stack on prime of one another,” Cotton stated. “We use this to make the argument to native and state leaders that one thing’s bought to be executed to handle this. We have to make our laws extra versatile. We have to permit for extra of most of these lacking center houses in our communities to handle our housing disaster,” he stated.
Turning a wall of paper maps and unhealthy information right into a GIS zoning atlas
Nonetheless, mapping out 13 counties in Montana was no small feat for the Frontier Institute’s staff of three workers, who had no background in GIS. Luckily, Cotton stated the GIS instruments had been “fairly user-friendly.”
The most important carry in growing the Atlas was the handbook information assortment course of. In some circumstances, the Frontier staff needed to drive to metropolis data places of work to find bodily maps. Information high quality offered one other problem.
“There’s a variety of sort of unhealthy information on the market, as properly,” Cotton stated. “Plenty of these metropolis or county data had been stunning once we had been in a position to sort of pull them into the GIS methods.” One kind of discrepancy his staff observed was {that a} data workplace would possibly say it had a selected housing zone, nevertheless it wasn’t mapped out — “it did not exist on the map,” he stated.
As well as, some data places of work had bodily copies of their maps with the zoning districts drawn in with a highlighter. Cotton’s staff would scan them. “We needed to create our personal shapefiles with a view to put these zones on our map,” he stated. “It took tons of of hours of my employees and volunteers’ time.”
As well as, zones and laws are frequently altering, and Cotton famous that the atlas is a “time slice only for our interval of information assortment.”
“Our hope is that we laid the groundwork for future researchers to go in and possibly develop or frequently replace this, and I’ve advisable that to the state,” Cotton stated. “I actually imagine that this can be a useful resource of the general public curiosity that is helpful for people who find themselves making an attempt to construct issues within the state and for policymakers.”
Working carefully with the Nationwide Zoning Atlas mission was additionally useful in creating the Montana Zoning Atlas, Cotton stated. He defined that the nationwide mission supplies a standardized methodology, analysis papers and different sources which can be useful for studying GIS and creating maps.
Turning GIS maps into housing reform
In the end, these tons of of hours of information assortment and GIS mapping proved fruitful. The atlas was cited as justification for lots of the suggestions made by Montana Governor Greg Gianforte’s housing activity drive convened in 2022, Cotton stated. Montana handed a “massive bundle of housing reforms” in 2023 and 2025, he added.
By printing out maps from the Montana Zoning Atlas, Cotton’s staff may go to housing committee conferences with a map of Missoula, Montana, and evaluate it to the zoning map of Los Angeles. Cotton stated it was eye-opening for officers to see that Missoula’s sample of single-family houses was starting to resemble the sprawl of Los Angeles.
Missoula repealed and changed its land use plan and developed a brand new zoning code and new zoning map that “allows an 85% improve in housing capability in comparison with what they did earlier than,” Cotton stated.
“Now Montana is a frontrunner in statewide housing reform coverage, and it actually began with this basis of excellent information that we had been in a position to construct that clearly confirmed and demonstrated to native and state leaders that this was an issue that wanted to be addressed,” Cotton stated.
Increasing GIS into training and healthcare
The Frontier Institute is now making use of its GIS abilities to different mapping tasks, together with the Ed Navigate Montana mission, which supplies dad and mom with info on native training choices for his or her kids. The Frontier Institute is utilizing GIS to construct out a map device for folks to establish close by colleges. The suppose tank has additionally began a mission to map out the supply of inexpensive, free-market healthcare suppliers — money pay and membership-based clinics — in Montana, Cotton stated.
“[GIS] permits us to take our coverage work to the following stage and provides individuals sources that are extraordinarily impactful and helpful, quite than simply publishing a PDF white paper on our web site, like a variety of conventional suppose tanks do. We’re offering information and knowledge visualized in a method that is extraordinarily helpful for individuals now who’re on-line,” Cotton stated.
