Continental Mapping Sun Prairie: Mapping the Future from Wisconsin

If you have any interest in mapping, geospatial tech, or how cities plan their infrastructure, you may have heard of Continental Mapping in Sun Prairie, Wisconsin. Over the years, that name has come to represent a key player in aerial mapping, surveying, and spatial data. In 2022, the company rebranched to Axim Geospatial, but many locals and clients still refer to it as Continental Mapping.

In this article, I want to walk you through who they are, what they do in Sun Prairie and beyond, why they matter locally, and what their future might look like. I’ll try to write this in a simple, straightforward way—imagine I’m explaining it over coffee to a friend who’s curious about mapping companies. I’ll also include examples, pros and cons, and advice for people thinking of hiring them.

2. Company Background & Evolution

Founding and Original Mission

Continental Mapping Consultants was founded to fill a growing need: high-accuracy mapping, photogrammetry, surveying, and spatial data services for both private and public clients. Their work depends heavily on having the right hardware (like aerial cameras, drones, GPS) and software (GIS, image processing). Over time, they built a reputation for strong technical capability.

Growth & Reaching a National/Global Scale

Though based in Sun Prairie, Wisconsin, they didn’t stay a small local firm. They expanded by winning contracts, acquiring smaller players, and increasing their geographic reach. Their staff grew, their technology investments increased, and they started taking on projects at state, federal, and even international scales.

2022 Rebrand to Axim Geospatial

A big moment came in 2022: Continental Mapping merged with or reorganized under the name Axim Geospatial. The existing businesses and contracts were preserved, but newer work is now under the Axim brand. The headquarters remain in Sun Prairie. This rebranding signals their ambition to integrate services, present a unified identity, and compete more widely in the geospatial sector.

Offices and Reach

While the “Sun Prairie location” is their flagship or original address, they now operate in multiple states. Their reach is broad—they have contracts across the U.S. and mapping footprints around the world.

Because of that reach, local clients benefit from a firm that has both local presence and national experience.

3. Core Services Offered in Sun Prairie / Wisconsin

What exactly do they do? The services break down into a few major categories. As a client, these are the things you might ask them for.

Photogrammetric Mapping

Photogrammetry is the process of using overlapping aerial or drone photographs to derive accurate measurements (distances, elevations, contours). You fly over an area, capture many images, then software stitches them and computes geometry.

In practice, Continental Mapping / Axim will fly drones or manned aircraft equipped with high-resolution cameras or LiDAR sensors. Then they generate orthophotos (geometrically corrected images), digital elevation models (DEMs), contour maps, 3D surface models, etc.

This is a core strength of theirs—and one of their flagship offerings.

Aerial Imagery / Remote Sensing

Beyond just mapping, they offer aerial photography, multispectral or hyperspectral imaging, thermal imaging, or other remote sensing techniques. These are useful for land use analysis, vegetation health, urban planning, environmental monitoring.

For example, a municipality might ask them to map how vegetation is changing over time, or a utility company to inspect transmission corridors using aerial imagery to detect encroaching vegetation.

GIS & Spatial Data Services

Maps are useful, but their real power comes from being usable in GIS (Geographic Information Systems). So they also provide:

• Data processing and cleaning

• GIS database creation and management

• Overlay analysis, spatial queries

• Integration of remote sensing data into GIS

• Web mapping / map servers

• Custom map products tailored to client needs

If a city wants a web map overlaid with zoning, utilities, flood zones, etc., they can supply those services.

Land Surveying / Topographic Mapping

Surveys are essential in construction, site planning, roads, utilities. Continental Mapping provides land surveying, establishing control points, ground truthing, topographic data, boundary mapping.

For example, before a developer builds new houses, they need a topographic survey of the site (elevations, existing features, drainage). This is part of what they can supply.

Engineering / Project Support

Mapping or GIS work often supports engineering, architecture, or infrastructure design. They may assist with:

• Alignments and corridor mapping for roads

• Design overlays

• Utility planning

• Infrastructure monitoring

• Construction progress mapping

So they often operate in tandem with civil engineers, planning departments, or architects.

4. Technical Approach & Quality Assurance

It’s relatively easy to take pictures from the air nowadays. The harder part is ensuring accuracy, reliability, and useful outputs. Here’s how a high-quality mapping firm like this tends to operate.

Tools, Hardware & Software

• High-precision GPS / GNSS receivers

• Drones (UAVs) or manned aircraft with stabilized camera rigs

• LiDAR sensors (for detailed elevation data)

• Multiband or multispectral sensors for advanced imagery

• Software: photogrammetry packages (e.g. Pix4D, Agisoft, proprietary solutions), GIS software (ArcGIS, QGIS), image processing, error correction tools

They invest in calibration, sensor correction, and methods to reduce distortion.

Workflow: Field to Final Product

1. Planning phase – define area, flight plans, overlap, ground control points (GCPs)

2. Field data collection – aerial flights, drone flights, ground control point measurement

3. Data ingestion & processing – upload, align images, compute point clouds, DEMs, orthomosaic

4. Quality control & validation – check for errors, mismatches, misalignment

5. GIS integration & product generation – export maps, layers, deliverables

6. Delivery & client support – interactive maps, consultation

At each stage they check for misalignment, anomalies, missing data, distortions.

Accuracy, Calibration & Error Checking

One important claim a mapping firm must support is accuracy (e.g. horizontal error < X cm, vertical error < Y cm). They use ground control points (surveyed markers whose location is precisely known) to tie imagery to real-world coordinates. They also cross-check overlapping images to ensure consistency.

If they detect anomalies (e.g. sudden shifts, mismatches), they go back and re-fly or reprocess.

As a client, you should ask: “What is your stated accuracy? What baseline do you use? How many ground control points? Do you deliver metadata about error margins?” A good firm will provide this transparently.

Example / Case Study (Hypothetical)

Suppose a mid-size municipality in Dane County wanted to update its floodplain map. Continental Mapping flew a drone survey after a heavy rain season, collected thousands of overlapping images, used ground control points, processed into elevation models, then delivered contour maps, flood zone overlays, and GIS layers. The city compared those to older maps and found previously unmapped low spots. The updated map informed better storm drainage design.

That’s the kind of integration between field, mapping, and planning they can deliver.

5. Local Projects & Impact in Sun Prairie / Dane County

Because the company is physically based in Sun Prairie, they are well positioned to work with local governments, planning departments, and contractors in Dane County and surrounding areas. Their local presence gives them advantages: faster turnarounds, both field and office staff nearby, knowledge of region geography.

Sample Local Projects

While I couldn’t locate a public catalog of all their local projects, we can reasonably infer types of work they do:

• For city planners, updating basemaps and parcel maps

• Supporting utility expansions (e.g. water, sewer)

• Mapping infrastructure (roads, bridges)

• Flood mapping in local watersheds

• Site plans for new subdivisions

• Environmental monitoring streams or wetlands

Their local impact includes ensuring that planning is based on up-to-date, accurate geospatial data rather than outdated surveys.

Benefits to Local Community

1. Better planning and decision making: Local governments rely on accurate maps to plan roads, zoning, drainage, public works.

2. Cost savings: Having a competent regional mapping provider reduces travel/time costs vs hiring someone distant.

3. Faster updates / refresh cycles: When changes occur (new development, erosion, flooding), local mapping provider can respond more quickly.

4. Economic development: Developers feel more confident investing in areas where good survey and mapping infrastructure exists.

5. Public transparency: Good maps enhance public awareness (for example, flood risk zones available to citizens).

Because mapping is a foundational infrastructure in planning, having a strong local mapping firm helps the region function more effectively.

6. Comparisons & Advantages

When someone is deciding whether to hire Continental Mapping / Axim vs another local competitor, here are likely comparisons and how they might set themselves apart.

What They Do Differently

• Scale & Experience: Because they have national contracts and global reach, they bring best practices, mature workflows, and bigger resources.

• Technical capacity: They are more likely to own advanced sensors (LiDAR, multispectral) and sophisticated processing software.

• Reputation & Reliability: Established brand and client track record.

• Local + national presence: They combine local proximity with wide network and cross-project experience.

• Integrated services: With the rebrand, they can offer a more seamless set of services (mapping, GIS, consulting) under one roof.

Possible Weaknesses / Challenges

• Cost might be higher than small local firms.

• Turnaround in small niche jobs might not always beat a very local boutique firm.

• They may be less flexible in very small, ad hoc jobs.
