Remote Tree Surveys

Gentian delivers fast, remote tree surveys using high-resolution satellite imagery and AI-powered analysis. We help landowners, developers, asset managers and more map canopy cover and estimate tree counts, without the need for boots on the ground.

How our tree surveys work

Gentian uses sub-50cm resolution satellite imagery and proprietary AI to deliver fast, remote tree surveys with exceptional accuracy. We map canopy cover and estimate tree counts across urban, rural, or other natural settings.

Our models detect individual tree features where resolution allows and produce clear spatial outputs for planning, biodiversity assessments, and green infrastructure strategies.

Built for flexibility, our data supports ESG reporting and nature-related frameworks like TNFD, empowering organisations to understand, manage, and report on tree cover at scale.

What is a tree survey?

What is a tree survey for?


A tree survey is used to inform planning, development, and environmental decision-making. It helps identify the presence and extent of tree cover, assess potential ecological constraints, and guide compliance with urban greening targets, conservation regulations, or monitoring requirements.

Gentian’s remote tree surveys are ideal for scoping sites, supporting baseline assessments, managing green infrastructure, and contributing to ESG or TNFD-aligned reporting.

Why is a tree survey important for biodiversity?


Trees play a vital role in supporting biodiversity by providing habitat, food, and shelter for a wide range of species. They contribute to ecological connectivity, regulate microclimates, and enhance soil and water health, making them critical components of functioning ecosystems.

A tree survey helps quantify these natural assets. By understanding tree distribution, canopy cover, and changes over time, land managers and developers can make more informed decisions that protect and enhance biodiversity.

How Gentian can help with your tree survey report


Gentian provides fast, remote tree surveys using sub-50cm satellite imagery and advanced AI models. We deliver accurate data on estimated tree count and canopy coverage, without the delays or logistics of on-site visits.

Our outputs are provided as clear maps, spreadsheets, and GIS-ready files, making them easy to integrate into planning reports or ESG disclosures. Whether you're surveying a single site or a national portfolio, we help you generate high-quality, actionable tree data, quickly and at scale.

FAQs

How often should a tree survey be carried out?

The frequency depends on your objectives. For planning or BNG baselines, a one-off survey may be sufficient. For ongoing biodiversity monitoring or asset management, we recommend updating data annually or after significant environmental change.

How long does a tree survey take?

Gentian’s remote tree surveys are typically delivered within 3–5 working days. Larger or multi-site portfolios may take slightly longer, but we avoid the seasonal and scheduling delays of field-based surveys.

What information do I need to provide for a tree survey quote?

To provide a quote, we just need a site boundary (in any standard format such as a shapefile, KML, or a map screenshot) and an idea of what outputs you need, e.g., canopy coverage, tree counts, or BNG integration.
