There is not any shortcut to fixing the reasonably priced housing disaster within the U.S., however figuring out a logical approach to current housing knowledge is a essential first step.
Geographic data system (GIS) software program groups from town of Philadelphia and the Frontier Institute in Montana just lately spoke with InformationWeek about how they’re mapping out group knowledge 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 capable of transfer the needle on the reasonably priced housing disaster.
Half one in every of this collection focuses on how mapping out the upcoming sprawl of main hubs in Montana led to regulatory modifications. Keep tuned for half two, which focuses on reasonably priced housing challenges in Philadelphia.
How GIS mapping modified the housing debate in Montana
In Bozeman, Montana, native officers had been skeptical that regulatory reform may very well be an efficient approach to deal with the rising price of housing, stated Kendall Cotton, CEO of the Frontier Institute, a suppose tank based mostly in Helena. To visually clarify the potential impression of regulatory modifications on the housing disaster, Cotton and his crew determined to create the Montana Zoning Atlas. The interactive GIS map lets public officers and residents entry a visible illustration of Montana’s housing knowledge.

“Our purpose was to mainly clearly display how strict native zoning laws are making it tough to construct the properties we have to construct to maintain up with demand,” Cotton stated. “We ended up mainly making a profile for every main metropolis in Montana.”
Utilizing Esri’s ArcGIS software program, the Frontier Institute crew was capable of create color-coded maps displaying knowledge “down into the parcel stage,” Cotton stated. With the atlas, Cotton’s crew might visually display that present laws had been limiting the forms of properties that may very well be constructed on land parcels. Underneath present laws, single-family house builds had been outpacing multi-family dwellings.
The atlas additionally helped display “how laws stack on high of one another,” Cotton stated. “We use this to make the argument to native and state leaders that one thing’s obtained to be accomplished to deal with this. We have to make our laws extra versatile. We have to enable for extra of a lot of these lacking center properties in our communities to deal with our housing disaster,” he stated.
Turning a wall of paper maps and unhealthy knowledge right into a GIS zoning atlas
Nonetheless, mapping out 13 counties in Montana was no small feat for the Frontier Institute’s crew of three workers, who had no background in GIS. Thankfully, Cotton stated the GIS instruments had been “fairly user-friendly.”
The most important raise in growing the Atlas was the handbook knowledge assortment course of. In some instances, the Frontier crew needed to drive to metropolis data workplaces to find bodily maps. Knowledge high quality offered one other problem.
“There’s a number of form of unhealthy knowledge on the market, as nicely,” Cotton stated. “Loads of these metropolis or county data had been shocking after we had been capable of form of pull them into the GIS techniques.” One sort of discrepancy his crew observed was {that a} data workplace may say it had a selected housing zone, but it surely wasn’t mapped out — “it did not exist on the map,” he stated.
As well as, some data workplaces had bodily copies of their maps with the zoning districts drawn in with a highlighter. Cotton’s crew would scan them. “We needed to create our personal shapefiles as a way to put these zones on our map,” he stated. “It took a whole lot of hours of my workers and volunteers’ time.”
As well as, zones and laws are regularly altering, and Cotton famous that the atlas is a “time slice only for our interval of knowledge assortment.”
“Our hope is that we laid the groundwork for future researchers to go in and perhaps develop or regularly replace this, and I’ve really helpful that to the state,” Cotton stated. “I actually imagine that it is a useful resource of the general public curiosity that is helpful for people who find themselves attempting to construct issues within the state and for policymakers.”
Working intently with the Nationwide Zoning Atlas challenge was additionally useful in creating the Montana Zoning Atlas, Cotton stated. He defined that the nationwide challenge offers a standardized methodology, analysis papers and different assets which are useful for studying GIS and creating maps.
Turning GIS maps into housing reform
Finally, these a whole lot of hours of knowledge assortment and GIS mapping proved fruitful. The atlas was cited as justification for most of the suggestions made by Montana Governor Greg Gianforte’s housing activity pressure convened in 2022, Cotton stated. Montana handed a “huge bundle of housing reforms” in 2023 and 2025, he added.
By printing out maps from the Montana Zoning Atlas, Cotton’s crew might 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 properties 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% enhance in housing capability in comparison with what they did earlier than,” Cotton stated.
“Now Montana is a pacesetter in statewide housing reform coverage, and it actually began with this basis of excellent knowledge that we had been capable of 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 expertise to different mapping initiatives, together with the Ed Navigate Montana challenge, which offers mother and father with data on native training choices for his or her youngsters. The Frontier Institute is utilizing GIS to construct out a map software for fogeys to determine close by colleges. The suppose tank has additionally began a challenge to map out the supply of reasonably priced, free-market healthcare suppliers — money pay and membership-based clinics — in Montana, Cotton stated.
“[GIS] permits us to take our coverage work to the subsequent stage and provides folks assets that are extraordinarily impactful and helpful, moderately than simply publishing a PDF white paper on our web site, like a number of conventional suppose tanks do. We’re offering knowledge and data visualized in a means that is extraordinarily helpful for folks now who’re on-line,” Cotton stated.
