Nathaniel Pyron on GIS and the Installation Common Operating Picture: Mapping the Mission

Every installation master plan is, at its core, a stack of maps. The airfield clear zones. The noise contours. The floodplain. The explosives safety arcs. The historic districts. The utility corridors. The wildlife hazard zones. The standoff distances. No planner can hold all of that in their head, and no static PDF keeps it current. The geographic information system — GIS — is where the installation's many realities live together, and the planner who masters it masters the plan.

The common operating picture

The phrase comes from military operations, but it fits planning perfectly: a common operating picture is a single, shared, geospatial view of everything that matters, current enough to act on. On an installation, the GIS is that picture. When the public works director, the environmental manager, the airfield manager, and the master planner all open the same map layers, decisions stop being made from stale drawings in separate offices. A proposed barracks site can be checked against the noise contour, the accident potential zone, the historic district, and the stormwater network in minutes rather than weeks.

This is why the Department of Defense has invested so heavily in installation geospatial standards. Common data models mean a planner at one installation can read another's data, and enterprise systems let higher headquarters roll up installation data for portfolio-level decisions. The planner's job at the local level is less about collecting data — much of it already exists — and more about curating it: making sure the layers are current, documented, and actually used in planning decisions.

Layers that earn their keep

Not every layer matters equally. The layers that consistently decide installation planning outcomes are the constraint layers: the ones that say "no" or "not here." Airfield imaginary surfaces and clear zones. Explosives safety arcs around munitions areas. Floodplains and tsunami zones. Endangered-species habitat and wetlands. Noise contours. Accident potential zones. Antiterrorism standoff distances. Historic districts. Contaminated sites.

The planner's discipline is to keep these layers authoritative. A noise contour from a decade-old study, an explosives arc drawn before a magazine was demolished, a floodplain that predates the latest flood maps — each one is a decision waiting to go wrong. Nathaniel Pyron has learned that the most dangerous layer in any installation GIS is the one everyone trusts but nobody has updated. Data governance — who owns each layer, how often it is refreshed, what source it came from — is unglamorous work that prevents expensive mistakes.

Analysis the paper map could never do

GIS earns its keep not just as a map but as an analytical engine. Suitability analysis can score every parcel on the installation against a weighted set of criteria — mission compatibility, environmental sensitivity, infrastructure access, cost — and produce a defensible ranking of development sites. Viewshed analysis can test whether a proposed tower penetrates an airfield's imaginary surfaces before a single drawing is made. Buffer analysis can instantly show every building inside a revised standoff distance. Network analysis can model how closing one gate redistributes traffic across the installation.

For airfield planning specifically, GIS is close to indispensable. The airfield's imaginary surfaces are three-dimensional geometries — approach slopes, transitional surfaces, horizontal and conical surfaces — that must be evaluated against terrain and structures. Doing that by hand is slow and error-prone; in GIS, it is a repeatable computation. When a proposed antenna or wind turbine near the installation raises an obstruction question, the planner can answer it with geometry rather than guesswork.

The planner's data check

Three habits separate planners who use GIS from planners who are used by it. First, verify the currency of every constraint layer before it enters a planning alternative — check the study date, not just the layer name. Second, document the assumptions: which noise scenario, which flood map version, which explosive-arc standard. A map that does not say what it assumes is a rumor with a legend. Third, keep the picture shared: the GIS only works as a common operating picture if the people who need it can see it. Export the key maps, brief them in project meetings, and make sure the decision-makers are looking at the same picture the planner is.

Nathaniel Pyron's rule of thumb: the master plan is only as current as its GIS. A planner who treats the geodatabase as the plan's living memory — maintained, governed, and shared — gives every project on the installation the same head start: decisions made against reality, not against last year's drawing. Map the mission, and the plan follows.

The Sky Is Zoned Too: What Special-Use Airspace Means for Base Master Planning

Image
By Nathaniel Pyron Every planner knows a parcel has a zoning district. Fewer civilians realize the sky above it has one too. I'm Nathaniel Pyron, a military urban planner specializing in military master planning with an airport and airfield focus, and the "Airspace" half of my job title gets questions at every conference I attend. So here's the plain-English version: the military doesn't just plan the ground inside the fence line. It has to plan the air above it — and the two plans are inseparable. The Federal Aviation Administration calls it Special Use Airspace, or SUA: defined volumes of sky where military activities must be confined, and where nonparticipating aircraft face limitations. There are seven types: Prohibited Areas, Restricted Areas, Military Operations Areas (MOAs), Warning Areas, Alert Areas, Controlled Firing Areas, and National Security Areas. Two of them — Prohibited and Restricted — are regulatory airspace created through formal rulemaking;...

The 15-Minute Base: Bringing Walkable-City Thinking to Military Installations

Image
A compact, walkable military installation town center — the 15-minute base concept. Field notes I’m Nathaniel Pyron, a military urban planner specializing in military master planning with an airport and airfield focus. Most of my work comes down to one question: how does the layout of a place shape the lives of the people who depend on it? Lately, I’ve been applying a civilian planning idea — the 15-minute city — to a question the military has been wrestling with for years: why do so many of our installations feel less like communities and more like office parks you happen to sleep on? The 15-minute city, briefly The concept was formalized in 2016 by urbanist Carlos Moreno, and its premise is disarmingly simple: everything a person needs day to day — home, work, food, health care, school, a place to gather — should be reachable within 15 minutes on foot or by bike. It rests on four principles: proximity, diversity of uses, density, and digital services that reduce unnecessary trips....

AICUZ, Explained: What Can Be Built Near a Military Runway

Image
Aerial view of a military airfield with AICUZ clear zones and accident potential zones overlaid — the compatible land use map around the runway.   Field notes I'm Nathaniel Pyron, a military urban planner specializing in military master planning with an airport and airfield focus. Every airfield I've worked on — most recently as a community planner with the United States Marine Corps at Camp Blaz and in Darwin, Australia — has something a civilian airport usually doesn't: a second map laid over the first. The first map shows runways, taxiways, and hangars. The second one shows where you can and can't build — and it starts the moment you leave the pavement. That second map comes from the Air Installations Compatible Use Zone program, AICUZ. If you live or plan near a military airfield, it's the most important planning document you've never read. Here's what it says, and why it works. A program built to keep neighbors and missions safe The Department of De...
