How TerraGo created a new kind of map—and built the tools to make geographic information, more collaborative, and useful.

A map can be beautiful, technically exact, and full of critical intelligence—and still fail the people who need it most. The problem is rarely the map itself. It is the distance between the GIS project where the information lives and the field, meeting room, incident command post, or job site where a decision must be made. Large datasets may be difficult to move. Specialized applications may be difficult to deploy. An exported PDF may look right, yet leave behind the layers, attributes, location intelligence, and interactivity that made the original map valuable.

TerraGo has spent its history closing that gap. The company loves the PDF map because a map in PDF form is familiar, portable, printable, and easy to share. But TerraGo’s purpose has never been to make an ordinary static PDF. It is to make the PDF map smarter: connected to real-world geography, capable of carrying useful context, and practical for the people who must act on it. That idea is GeoPDF.

In 2005, TerraGo created the first geo-referenced PDF map and helped change what a map document could be. Working with Adobe and the Open Geospatial Consortium, TerraGo helped advance GeoPDF toward an open-standard approach. Today, TerraGo offers a focused suite of tools for producing high-quality GeoPDFs from the maps, models, imagery, and project information organizations already rely on. The goal remains straightforward: deliver the right geographic information to the right person in a form they can use.

The PDF Map, Reimagined

Traditional PDF maps solve a real problem. They preserve a map’s cartography, allow teams to send a consistent view to many recipients, and can be opened almost anywhere. For reviews, reports, permits, plans, and distribution packages, that accessibility is hard to beat. Yet a conventional PDF is usually a snapshot. It shows a map, but it does not necessarily know where it is. A user may be able to see a road, parcel, asset, contour, or boundary, but not interrogate it, locate themselves against it, or move easily between the map and the data behind it.

A GeoPDF adds geographic awareness to that familiar document experience. Its pages can be georeferenced, meaning the map content is associated with a real-world coordinate system. That foundation enables a document to do more than display an image. Depending on the way it is authored and configured, users can work with map layers, access information tied to features, measure locations, navigate a mapbook, view their GPS position, and add geographically meaningful notes or observations. The map becomes a portable operational product rather than a static export.

That distinction matters because maps are rarely created for their own sake. They support planning, maintenance, engineering, inspection, emergency response, environmental work, utilities, land management, asset operations, and countless other activities. In each case, the question is not merely whether a map can be produced. The question is whether the people using it can understand what they are seeing, trust what they are seeing, and use it quickly enough to make a better decision.

GeoPDF was designed around that practical reality. It preserves the convenience of the document while carrying more of the intelligence that makes a map useful. It can help an organization distribute authoritative information beyond the GIS department without requiring every stakeholder to work in a full GIS application. And because the product is portable, it can remain useful when connectivity is limited, when a recipient needs a file rather than a web application, or when a project record needs a durable, shareable deliverable.

A History Built Around Access

GeoPDF did not emerge from an abstract desire to make a file format more sophisticated. It emerged from the need to make critical geographic and engineering information usable away from the systems that produced it. TerraGo’s early work focused on delivering map and drawing information to the people responsible for real-world operations. Those users needed current, understandable information in a format they could carry, review, and use without becoming specialists in the source applications.

The insight was powerful: a map document could retain the accessibility that made paper and PDF products so universal while gaining the location intelligence of a geographic system. When geography is embedded in the document, a map can serve as a common operating picture. It can connect a field user to a position, a reviewer to an asset, a project manager to a page in a larger map series, or a decision-maker to a clearer understanding of conditions on the ground.

TerraGo’s work with Adobe and the Open Geospatial Consortium helped move that concept beyond a single closed workflow. The effort to establish an open standard mattered because organizations need map products that can travel: across teams, contractors, agencies, devices, and years of project history. A GeoPDF is built to make that travel practical without reducing a carefully authored map to a flat image.

Two decades later, organizations have more spatial data than ever. ArcGIS projects contain rich attributes and carefully designed layers. Imagery captures changing conditions. LiDAR and elevation data reveal the shape of the world in extraordinary detail. The need to share that information has only increased. The challenge is still familiar: how can an organization deliver the fidelity of its geospatial work to every person who needs it, not just the person with access to the original project and specialist software?

TerraGo’s answer is a suite of purpose-built GeoPDF tools. Each is designed for a different stage or type of work, but all are built around the same promise: use the information you have already created to produce a map product that is portable, interactive, and ready to support decisions.

Publisher for ArcGIS Pro: Preserve the Work You Built

For teams that build maps in ArcGIS Pro, the starting point is often a project containing far more intelligence than an exported PDF can show. It may include carefully styled layers, feature attributes, scale-dependent views, imagery, links to supporting material, and years of data stewardship. A basic print-to-PDF workflow can deliver a clean-looking page, but it can also strip away the very context that makes the project valuable to the people receiving it.

GeoPDF Publisher for ArcGIS Pro is designed to change that outcome. Working directly inside an ArcGIS Pro project, it lets GIS professionals transform their work into high-fidelity GeoPDFs while maintaining meaningful connections to the map’s layers, attributes, and geographic context. The goal is not to recreate an ArcGIS project in a different tool. It is to publish an accessible deliverable from the project where the work already lives.

That direct workflow matters for both quality and efficiency. Map authors can focus on the cartography and information design that their audience needs, then publish a GeoPDF configured for the purpose at hand. A field crew may need a concise map with the most relevant layers and links to reference material. A stakeholder may need an interactive review product that makes it easier to understand a proposed change. A project team may need a document that supports questions, comments, and location-aware feedback. In each case, the GeoPDF can be designed as a deliberate product rather than an afterthought.

Publisher for ArcGIS Pro helps organizations extend the value of their ArcGIS investment. Instead of keeping important geographic information inside a specialist environment, teams can put a dependable representation of that information into the hands of a broader audience. The recipient does not need to reconstruct a GIS workflow just to understand the map. They receive a product built for viewing, sharing, and action.

The practical result is fidelity with reach. The work that went into layers, attributes, and data organization is not treated as invisible back-end effort. It becomes part of a map experience that can travel to the field, across departments, and into conversations where decisions are made.

GeoPDF Composer: Turn Map Sheets into One Connected Resource

Many organizations do not have just one map. They have map series, plan sets, legacy PDFs, tiles, regional coverage, and hundreds—or thousands—of pages that must be understood together. That creates a different kind of problem. A single sheet may be useful, but a collection of disconnected sheets forces users to hunt for the right page, lose context at sheet edges, and manage updates manually. The more extensive the coverage, the more costly that fragmentation becomes.

GeoPDF Composer is built for this challenge. It enables teams to take large collections of map sheets and create a seamless GeoPDF mapbook. Instead of treating every page as an isolated file, Composer turns the collection into a connected resource. An index map can guide users to the right page. Pages can be linked for intuitive navigation. The mapbook can carry the geographic context that makes movement through the collection feel purposeful rather than cumbersome.

This capability is especially valuable when a project depends on broad coverage and local detail at the same time. A user can begin with an overview, identify an area of interest, and move into the detailed sheet that supports the task. The relationship between pages is preserved. The person holding the mapbook does not need to know its internal filing convention, decipher a naming scheme, or manually piece together adjacent sheets to understand the larger picture.

Composer also helps organizations bring existing map assets into a more useful workflow. Many teams have PDFs created over years of projects—documents that contain important cartography but lack registration, navigation, or a connection to a larger map product. With GeoPDF Composer, those assets can be georegistered, organized, and incorporated into GeoPDF-based deliverables. That makes it possible to add value to existing work rather than starting over.

Updates are equally important. Map products are not static when the world, the project, or the data changes. By organizing map sheets into a connected GeoPDF mapbook, teams can manage a repeatable publishing process that carries current information through the deliverable. The result is a more coherent experience for the end user and a more disciplined process for the organization that produces the maps.

GeoPDF Composer is, in short, the answer to “we have a lot of maps.” It makes it possible to turn a collection into a system of pages that work together—every page connected, every update carried through, and every user better able to find the information they need.

3D Composer: When the Mission Needs Another Dimension

Some geographic questions cannot be answered adequately from above. Terrain can hide or reveal a route. Elevation can change the feasibility of a design. A structure’s relationship to its surroundings can be difficult to communicate on a flat page. In these situations, the Z axis is not a visual extra; it is part of the decision.

3D Composer extends the GeoPDF concept into this third dimension. Using LiDAR, terrain, imagery, or elevation data, teams can generate an interactive 3D GeoPDF that makes complex spatial relationships easier to see and share. Instead of asking every stakeholder to open a specialized 3D system, organizations can deliver a compact, familiar document that presents the model in context.

That accessibility is the point. Technical teams may be able to navigate source data and sophisticated modeling environments, but decision-makers, partners, field personnel, and community stakeholders often need a faster path to understanding. A 3D GeoPDF can show the relationship among terrain, imagery, and features in a form that supports discussion. It can be used alongside 2D maps, project descriptions, photographs, and other documentation, giving every audience a clearer view of the place and conditions being discussed.

Portability also matters. High-resolution 3D data can be large and demanding. A well-produced 3D GeoPDF packages the visual and geographic insight into a more practical file for sharing and review. It gives people a way to view and communicate about the work without asking them to manage the underlying source datasets. The model becomes an understandable part of the project record and a useful part of the decision process.

For missions involving terrain, elevation, infrastructure, visibility, or physical context, 3D Composer provides another way to carry the truth of the landscape into the room. It unlocks the Z axis so stakeholders can move beyond a flat interpretation and see the spatial relationships that matter.

Not Better PDFs—Better Outcomes

Publisher for ArcGIS Pro, GeoPDF Composer, and 3D Composer address different needs, but they share a common purpose. Publisher helps ArcGIS Pro users create high-fidelity GeoPDFs directly from the work they have built. Composer helps organizations turn many sheets and legacy documents into connected, navigable mapbooks. 3D Composer helps teams share terrain and model-based insight in a portable form that more people can understand.

Together, these tools help an organization make geographic information more available without making it less meaningful. They support a workflow in which a map does not stop at the GIS desktop. It can become a field-ready reference, a connected atlas, a collaborative review document, or an interactive 3D communication tool. The information can travel farther while retaining the context that makes it trustworthy.

That is what TerraGo has been building since day one: not simply better PDFs, but better decisions, better collaboration, and better situational awareness. The map remains familiar. The difference is what it can do for the person using it.

Start Your GeoPDF Workflow

The most powerful map is not necessarily the most complex one. It is the map that puts the right information in the hands of the person who needs it, at the moment they need it, in a form they can confidently use. With TerraGo GeoPDF, your team can carry the fidelity of its GIS projects, map collections, and 3D data beyond the desktop and into the real world.
