Mapping Trees to Protect Places
How Tree Mann Solutions uses Bad Elf GNSS and field GIS to preserve trees, inform design, and protect the places people value.

At Tree Mann Solutions, the team knows a tree is more than a trunk at a coordinate.
A tree can shade a sidewalk, frame a home, anchor a park, absorb rainfall, filter air, support wildlife, and become part of how someone remembers a place. Before protecting that tree, however, people need to understand where it is, how large it is, what condition it is in, and how its canopy occupies space.
That makes tree preservation a spatial problem.
It also makes good mapping part of good arboriculture.
Tree Mann Solutions knew there was a better way to inventory.
When Sydney Dwoskin joined Tree Mann Solutions roughly five years ago, much of her work involved tree-condition assessments. The trees had already been surveyed, while she navigated through the woods using static PDF maps on her phone.
Tree Mann began moving its field workflow from static PDFs into Fulcrum, giving arborists interactive tree points over aerial imagery instead of asking them to interpret a static sheet in the woods.
The next step felt natural: if Tree Mann’s arborists were already standing beside the trees, why not collect their locations too?
That question helped bring Bad Elf GNSS into the Tree Mann field kit.
Today, Tree Mann uses digital data collection and Bad Elf positioning to support tree inventories, condition assessments, canopy mapping, planning, and preservation work across Texas. The team collects tree locations, documents conditions, and gives planners and engineers spatial information much earlier in the design process.

Map it before the design hardens
Timing matters.
On a large development site, an engineer may be deciding where roads, homes, utilities, amenities, or buildings should go. Moving those elements is much easier during conceptual design than after drawings, permits, and construction plans are complete. Modern digital tree inventories give those AEC teams an early look at what already lives on the site.
- Where are the large trees?
- Which trees might influence a roadway alignment?
- Where does an important canopy extend?
- Can a building shift slightly and preserve a heritage tree?

Sometimes the client needs a formal land survey that meets specific municipal requirements. In jurisdictions such as Austin, Tree Mann may require a Registered Land Surveyor’s help to complete the task. In other situations, Tree Mann’s job is to give the design team an early spatial inventory of trees so they can make smarter decisions before they commit to a plan.
That distinction matters.
The map does not preserve the tree by itself. It gives people a chance to design around it, but the canopy matters too! A point tells the team where the trunk is, yet it does not tell the whole story.
Tree Mann also uses Bad Elf to map drip lines and canopy extents. That information helps architects, engineers, and planners understand how much physical space a tree occupies before they place buildings, roads, grading, or other infrastructure around it.
For early planning, this can provide a practical and affordable view of the existing canopy. More advanced LiDAR and 3D modeling take the analysis further, especially around complex buildings and heritage trees.
Sydney sees those technologies becoming increasingly important, but she does not expect them to replace arborists in the field. Dense brush, vines, canopy, and complicated trunks still demand human eyes and boots on the ground.
Technology extends Tree Mann’s expertise.
It does not replace it.
Accuracy takes more than buying a GPS
Tree Mann Solutions’ transition was not instant. The team had to learn GNSS best practices, Fulcrum, RTK corrections, coordinate systems, and quality-control procedures. Sydney describes the training as critical to that process.
“Bad Elf’s workshop training helped so much!”
As the projects became more sophisticated, accuracy became more important for Tree Mann. The team added RTK corrections, standardized coordinate-system practices, and worked with professional surveyors to check its data and improve field techniques.
Consequently, trees also create one of the tougher environments for GNSS!

Leaves, branches, trunks, buildings, and surrounding structures can interfere with satellite signals. Tree Mann does not assume every point is perfect just because a receiver reports a coordinate. The team prides itself on checking its work.
Sometimes the tree itself creates the error
Consider a 36-inch heritage tree. If someone stands at the edge of the trunk and collects a perfectly accurate GNSS position, the coordinate may still sit about 18 inches from the center of the tree. A 50-inch trunk creates an even larger offset.

The GPS can be right while the mapped tree is wrong.
Land surveyors helped Tree Mann refine the technique needed to map difficult situations like these. Instead of forcing a receiver against a large trunk, field technicians can occupy positions away from the tree, measure distance and direction to the trunk center, and calculate the actual center through intersection.
That combines GNSS accuracy with field craft.
For a heritage tree sitting beside a proposed building, a couple of feet matter!
Trees are a vital resource
People often talk about resources as energy, water, minerals, infrastructure, or land.
Trees belong in that conversation. Full stop.
Research consistently shows that urban trees provide measurable ecosystem and human benefits. A U.S. Forest Service study estimated that trees and forests removed 17.4 million tons of air pollution across the contiguous United States in 2010. Researchers estimated the associated health value at $6.8 billion, including more than 850 avoided deaths and 670,000 avoided cases of acute respiratory symptoms (Nowak et al., 2014).
Trees also help cool places. A 2025 review of 115 studies found that urban trees consistently provided stronger cooling than other vegetation types, particularly where dense, tall canopies provided meaningful shade (Alonzo et al., 2025).
An inventory tells people what resources already exist.

And in a time when water, shade, habitat, land, infrastructure, and healthy communities have never been more critical, knowing what exists is clutch. People cannot deliberately manage a resource that has never been inventoried. The connection becomes even stronger when considering human health.
A 2015 study in Toronto combined detailed street-tree data with health information. Researchers found that 10 additional trees per city block were associated with better self-reported health comparable to being seven years younger or having roughly $10,000 more annual income (Kardan et al., 2015). The study showed association rather than proving that trees caused the difference, but the scale of the relationship is striking.
Nature also affects the mind. In a Stanford-led experiment, participants who took a 90-minute walk in a natural environment showed reduced self-reported rumination and reduced activity in a brain region associated with rumination. Participants who walked through an urban environment did not show the same change (Bratman et al., 2015).
People experience trees emotionally, too!
A 2024 study involving 638 residents found connections between urban canopy, satisfaction with tree-related benefits, and attachment to home, street, and neighborhood. Residents associated trees with sense of place, social interaction, and fresh air. Researchers also noted that losing trees can become “a source of distress and solastalgia” (McGrath et al., 2024).
That is placemaking.

A mature tree can become the thing people give directions by. It can be the shade where neighbors talk, the oak children climb, the canopy over a trail, or the tree someone notices is missing before noticing the new building that replaced it. These relationships help explain why urban forests can contribute to attachment to home, street, neighborhood, and a broader sense of place (McGrath et al., 2024).
Think about a place you love.
There is a good chance a tree is somewhere in the picture.
The coordinate connects to the person.
That is the larger story behind geospatial technology like Bad Elf GPS.
Bad Elf helps Tree Mann establish location. Fulcrum helps the team organize the field record. RTK, coordinate systems, training, and surveyor collaboration help improve confidence in the data.
Tree Mann’s arborists supply the part technology cannot: species knowledge, condition, context, judgment, and an understanding of what that tree means to the landscape.
Put those pieces together and the result travels far beyond a GPS point.
Want to become an arborist?
Sydney has simple advice for anyone considering this profession: be ready to work outside.
She knows the heat, early mornings, poison ivy, insects, and physical work are real. She also knows the reward. “There’s no substitute for that life.”

For aspiring arborists, Tree Mann Solutions recommends a few practical steps:
- Learn the trees first. Field identification, biology, soils, risk, health, and proper tree care remain the foundation.
- Learn the technology too. GIS, GNSS, mobile data collection, imagery, and eventually LiDAR can make someone dramatically more useful to a modern arboriculture team.
- Explore ISA. The International Society of Arboriculture supports arboricultural research, education, credentials, and professional development. ISA certification can provide a strong professional pathway as experience grows.
- Know ASCA. The American Society of Consulting Arborists focuses on professional consulting, including inventories, risk assessments, planning, appraisal, and tree protection during construction. Its education and professional network can help arborists move deeper into consulting practice.
- Network relentlessly. Meet surveyors, landscape architects, planners, engineers, GIS professionals, developers, and other arborists. Attend ISA chapter events, ASCA programs, GIS meetings, and local professional conferences. The best field technique someone learns next may come from a neighboring profession.
Most importantly, go outside and hug a tree! Look at the trees in the places you love. Notice their shade, scale, smell, sound, and the space underneath them.
Then imagine that place without them. That is why arborists map.
