Precision Tree Data with GIS: Why Accuracy Matters in Tree Surveys

In the world of arboriculture and land management, precision matters. Whether you're a planner, architect, engineer, or estate manager, access to accurate, science-based tree data is essential for informed decision-making. At GEOTREE Ltd, we combine professional expertise with cutting-edge technology to deliver tree surveys that are not only detailed, but also spatially accurate — thanks to Geographic Information System (GIS) and GNSS (Global Navigation Satellite System) tools.

High-Accuracy Field Data Collection

Every effective tree survey starts in the field. GEOTREE uses state-of-the-art GNSS equipment that provides centimetre-level accuracy, capturing the exact location of each tree or group of trees. This precise geotagging means every data point is tied to real-world coordinates — significantly improving both the reliability and usability of the information collected.

Mapping with Intelligence: The Role of GIS

Once data is collected, it’s mapped and presented using advanced GIS (Geographic Information System) technology. GIS allows complex data to be organised into intuitive ‘layers,’ each representing different types of information — such as:

• Tree species
• Age class
• Condition or health status
• Canopy spread or Root Protection Areas (RPAs)

This layered structure provides a clear visual context, helping clients understand not just where trees are located, but also how they relate to one another and the land they occupy.

Why This Matters

The GIS-based approach transforms raw data into decision-ready information. Here’s how it benefits landowners, developers, and professionals alike:

Categorisation of Data
Layering enables clear separation of key attributes, such as age class distribution or species type, making it easier to interpret large volumes of information.

Enhanced Visualisation
Management strategies — whether for preservation, pruning, or removal — can be supported with mapped visual overlays that clarify priorities and on-the-ground realities.

Integration with Other Plans
GIS outputs can be exported and merged with topographical surveys and architectural drawings, streamlining planning applications and informing the development of tree management plans.

The Value of Professional Cartography

Behind the technology is the human expertise. GEOTREE’s GIS mapping is handled by a qualified and experienced cartographer, ensuring each map is accurate, clear, and fit for purpose. Clients receive reports in both digital and hard copy formats, making them suitable for planning submissions, internal strategy, or long-term land management.
