Analysis of hyperspectral data using Sentiel satellite images. METRUM’s subsidiary company developed the kmi.lv system, within which it is possible to use Sentinel data.


Purpose: Identifying species is one of the most important tasks, the results of which depend on all further activities and results of forest management planning. The studies carried out so far show that the implementation of this task using remote sensing data is problematic and that the obtained results are not sufficiently accurate to be able to solve planning tasks based only on this information. As part of the European Space Agency’s “Copernicus” program, the Sentinel-2a and Sentinel-2b satellites were launched in 2015 and 2017, which provide high-resolution multispectral image acquisition, and one of the purposes of their use is the observation of vegetation, soil, water bodies and marine territories. Sentinel satellites acquire images with a resolution (pixel projection size on the ground) from 10 to 60 m and 12 channels, the frequency of image acquisition for one satellite is 10 days, so using data from both satellites, it is possible to survey one area every 5 days (rarely taking account for clouds). Previous studies on the use of remote sensing data show that the best results of species detection are obtained when working with multispectral images, however, although the results obtained in the studies are quite good, their practical use is limited by data availability and acquisition options, which could be solved using easily available Sentinel data.

Result: kmi.lv platform

Technology for remote sensing of forest taxonomy data (AMT technology) using hyperspectral sensor and aerial laser scanning data.

Purpose: To develop a new technology for remote determination of forest tax data, which can be integrated into the forest inventory process using hyperspectral sensor and aerial laser scanning data.

Result: Algorithms for data processing and forecasting assortments.


LIDAR KMI improvement: MNKC project 2014/2015, Funding agreement No. 4-02/P11, 4-06/53-P11, 1-06/19. The total amount of the project is EUR 264,868, support is EUR 159,599. SIA METRUM investment is EUR 105,269. To evaluate the possibilities of using LIDAR and aerial photo data for more effective forest management planning and to conduct a study of the possibilities of using the “LIDAR KMI” method in the preparation of the felling stock and forecasting the results of assortments.

LIDAR KMI – the beginnings of data application. “Development of SIA METRUM new forest inventory technology” – Project development – 2009-2011. (Priority 2.1 “Science and innovations”, measure 2.1.2 “Innovations”, activity “Development of new products and technologies”, sub-activity “Development of new products and technologies”) Project application number : JPI/, project contract number: L-JPI-09-0073. The total amount of the contract – 881,324 lats (without VAT), respectively EUR 1,254,011. Co-financing from the ERDF fund – 288,302 lats, respectively EUR 410,217. In total, SIA METRUM invested EUR 843,794 in research and product development. A total of 43,026 working hours were invested in the research.

The new technology will solve the main problems of forest taxation – subjectivity of the assessor, execution time, consumption of human resources, costs. The goal of the project is to develop a fundamentally new forest inventory technology, where data collection is ensured with the help of a specially equipped aircraft, only by flying over the object of interest, while the analysis of the collected data is provided with the help of specialized software.
In order to do this, first of all, an industrial study will be conducted and new knowledge and techniques will be obtained, on the basis of which the second part of the project – the experimental development of the software – will be implemented.
The successful implementation of the project will be ensured by the participation of scientists from the Latvian Agricultural University. The computer program contains data flow algorithms and calculations for collecting equal parameters for given plot sizes, a method for data collection and calculations.


METRUM wins the 3rd place in the competition “Export and Innovation Award 2009.” On November 4, 2019, in the framework of the 2nd round of the Most Innovative Product competition category, “Metrum” presented to the LIAA commission the creation of airfield obstacle maps using the laser scanning method, which is a novelty worldwide. At the moment, “Metrum” is the only company in Eurasia that has prepared a scheme of technical solutions in order to be able to carry out the survey, inventory and mapping of objects dangerous to air navigation in the vicinity of the airfield, in compliance with the requirements of Annexes 14 and 15 of the International Civil Aviation Convention.

Purpose: Development of airport obstacle maps, development of methodology, using the latest possible methods – LIDAR and aerial photo data.

The result: the use of LIDAR technology in the development of aeronautical maps. The methodology was introduced and later applied in the surveying of all airports in Kazakhstan. Partly in Armenia, Lithuania and Latvia.


METER | a multidisciplinary company with the aim of providing qualitative and innovative solutions in surveying, territory planning, obtaining geospatial information. METRUM started its active operation in the Latvian market in 2005, bringing together experienced and professional surveying, territory planning and geospatial information specialists in the company. Laser scanning and aerial photography equipment, Pilatus PC6 aircraft were purchased.

In 2005, we introduced the newest type – hitherto unused in Latvia – ADS type camera for obtaining aerial photos, the main difference is that the pictures are taken similarly to scanning – when one picture is up to 20 kilometers long. Difference from Frame (frame) cameras, data processing speed and quality in forest area.
