KATAM™ Forest Pro

  • Digital forest measurement in your smartphone
  • High precision and traceable measurements
  • Produce stand statistics and maps
  • Export of measurement data

KATAM™ Forest Pro is a modern and flexible tool for anyone working with forest measurement. Whether you are a buyer, seller, manager, advisor or consultant, you benefit from the digital opportunities. With Katam’s app in your smartphone, you replace traditional analog measuring tools. You direct the camera towards the forest and after a short recording you receive extensive measurement data for the sample surface.

Flexible test surfaces and extended measurement results
The digital technology enables fast and smooth measurement of extensive test surfaces, which are also flexible in shape and size. For measured sample areas, basal area, average diameter, trees/ha and volume/ha are reported. The GPS coordinates are saved and you can see the sample area boundaries as well as all detected trees plotted on the app’s map. By merging sample areas within a stand, data for all or part of the stand can be reported.

For each compilation at the stand level, diameter, and tree species distribution are also reported. You specify either the mean height of the test surface or the tree height manually for specific trees. Average heights can also be imported from other databases. With the help of drone photography and KATAM™ Treetop Detection, you also have the opportunity to supplement the measurement with all the individual tree heights in a stand.

Field adapted technology
All calculations and processes run locally on the phone and therefore do not require connection to the internet. A test area of 400 m2 usually takes less than a minute to record. A 20-second recording normally only takes a few minutes to process.

Export of measurement data to other systems
Measurement data from individual sample areas or compilations at the stand level can be exported locally to a master list in Excel format. In the file, each tree’s position, diameter, height, volume and tree species are marked. The file can then be imported into GIS tools or calculation tools.

Working method
With the app you can easily insert sample surfaces perpendicular to your own walking direction. A deployed sign serves as a reference. While the video is being processed locally in your phone, you can record additional sample areas. When the calculation is complete, you review the video where a 3D model is now marked on trees and terrain. In this way any deviations are made visible and you have the opportunity to correct these manually.

Limitation of functionality
KATAM™ Forest works well today for thinned production stands. The app is not adapted for stands that are younger, unthinned or with substantial under vegetation, see detailed description of supported forest environments.

Download the KATAM™ Forest smartphone app
KATAM™ Forest Pro works on most modern smartphones with Android 8+ and at least 3GB of RAM. KATAM™ Forest Pro is available online as a public beta.
Get it on Google Play
If you want to test the basic functionality of your phone before you purchase a license, you can download the free version of KATAM™ Forest Mini. See also currently supported devices.

KATAM™ TreeMap

Online service that returns improved forest inventory
data from your own standard drone recordings:

  • List of geoposition and characteristics of each individual tree
  • Analysis of stand density and growth variations within the stand
  • Optional delivery within 24h

Take control of the thinning and harvesting operations using KATAM™ TreeMap. By minimizing your in-optimal losses, the net value will increase! Simply upload raw drone photos of an entire stand to Katam cloud service and receive detailed forest inventory, tree by tree.

Optimized forestry management based on individual tree data
KATAM™ TreeMap returns the position and characteristics of each individual tree. This allows you to analyse the stand’s local variations regarding stand density, height and species. With such detailed information, you can efficiently perform planning and follow-up of your forestry operations.

Strategic analysis over time
When you upload consecutive drone recordings, KATAM™ TreeMap will match tree by tree and compare data to determine local variations of e.g. thinning strength, height growth, Stand Index within the stand. By comparing data before and after thinning, you will receive valuable input for quality assessment of the forestry operations. The distribution of spatial area per tree helps you determine whether the thinning operation has made the stand more economically viable.

Combine with the KATAM™ Forest smartphone app for improved decisions
KATAM™ TreeMap can optionally match your drone recordings with ground based plot measurements from KATAM™ Forest smartphone app. The inventory data set will then be extended with individual tree diameter information from plot measurements, which allows determination of well defined diameter/height ratio functions. By extrapolation to the entire stand, KATAM™ TreeMap delivers complete tree lists with high accuracy volume estimations on individual tree level.

KATAM™ TreeMap cloud service
Within down to 24 hours after uploading your drone recordings, KATAM™ TreeMap cloud service will deliver a geo-referred list of trees in Excel format, together with a high resolution orthomosaic. Each tree in the list is specified by its position, height, diameter, volume, species, spatial index and detection ratio (?). The list of trees can then easily be exported by the customer to any GIS tool, such as QGIS. In addition, KATAM™ TreeMap generates various predefined reports, which can be customized upon request. The service also includes analysis of generated tree maps over time as well as integration with KATAM™ Forest plot measurements.

Drone recording 
You can carry out the video recordings using standard consumer drone equipment. A normal DJI drone can cover up to 30 hectares, using one battery with a mission flight time less than 20 minutes. In that time it collects 200-300 photos.
