Implementation of satellite data on changes in the agrarian structure/program of agricultural works.
About this good practice
Using satellite data in analyses on programming and implementation of agricultural works to optimize the results based on current spatial information.
Resources needed
Due to the use of open data, the practice does not require direct involvement of financial resources. It is necessary to systematically obtain data and carry out analyses by an employee with knowledge and skills in programming agricultural works and GIS software together with programming elements.
Evidence of success
The change in the methodology of land use change analysis has made it possible to visualise the dynamics of the ongoing phenomena (e.g.: Fig. 1 and 2, "Images" section). An alternative quantitative summary of the agricultural area acc. to cadastral data is shown in Fig. 1. As can be seen, significant update of cadastral data took place in 2018-2019, indicating the particularly low utility of this data. The use of satellite imagery was a key condition for the reliability of the survey results.
Potential for learning or transfer
The practice can be adapted to the needs of operators in other European regions due to the wide availability of satellite data under the Copernicus programme and the simple and universal methods of processing and interpreting spatial information. Differences between methodological and legal standards in different countries and regions can be a factor hindering the interregional transfer of good practices. However, the technical solutions used, including the criteria for reclassification of land cover forms to land use, can be suitably modified and adapted to the respective cadastral system. On the other hand, in areas where the legislation does not provide for the monitoring of land use changes or requires the use of other strictly defined methods, it is possible to implement the proposed practice for research and control purposes.
