Laboratory for Remote Sensing and GIS – LaDIGIS
LaDIGIS is Oikon’s Remote Sensing and GIS Laboratory which provides better horizontal link between Oikon’s departments, more successful transfer and application of knowledge, and enhanced research and development work related to the use of remote sensing methods in projects.
The use of the latest technologies and sensors in the field of remote sensing, such as LIDAR, multispectral and radar satellite imagery, enables us to achieve effective mapping of changes in land use, fires, soil and forest site index, health status, spatial composition of tree / forest type / agriculture types or determining the amount of biomass in inaccessible areas. All this has already been successfully implemented in many of our projects. We also provide support within the company by developing land cover layouts of higher resolutions that are necessary for better assessments of environmental impact.
Being aware of the rapid development of technology and the spread of their application, the members of our Laboratory regularly attend all the relevant trainings (ESA / NASA / EARSEL) and conferences where they adopt new knowledge and conduct dissemination of the existing knowledge.
The head of the Laboratory is Ivan Tomljenović, PhD. and his deputy is Ivona Žiža, mag. ing. agr.
The Laboratory has worked / is working on the following projects:
- Carbon sink assessment in dead organic matter and average wood stock assessment in maquis, shrubbery and first age class stands in Croatian forests
- Application of high resolution multi-spectral satellite images in determining the degree of productivity and age of uneven age forest stands of forest owners in the Mediterranean and sub-Mediterranean
- Service acquisition upgrade of existing CORINE database, validation of thematic database generated by interpretation on satellite images and WEB GIS browser creation
- Project Design services for Areas with Natural Restrictions or Other Special Limitations with Calculations with determination of Value Indicator No. 41 “Organic Substances in the Ground” and number 42 “Soil Water Erosion” for the Program Period 2021-2027
- Monitoring of forest ecosystems at the multipurpose Danube – Sava canal.
