An advanced classification method for urban land cover classification
51-57Views:214This manuscript presents a detailed comparative analysis of three advanced classification techniques that were used between 2018 and 2020 to classify land cover using Landsat8 imagery, namely Support Vector Machine (SVM), Maximum Likelihood Classification (MLSC), and Random Forests (RF). The study focuses on evaluating the accuracy of these methods by comparing the classified maps with a higher-resolution ground truth map, utilising 500 randomly selected points for assessment.
The obtained results show that, compared to MLSC and RT, the Support Vector Machine (SVM) approach performs better. The SVM model demonstrates enhanced precision in land cover classification, showcasing its effectiveness in discerning subtle differences in landscape features.
Furthermore, using the precise classification results produced by the SVM method, this study examines the temporal variations in land cover between 2018 and 2020. The results provide insight into dynamic land cover changes and highlight the significance of applying reliable classification techniques for thorough temporal analysis with Landsat8 images.

The Legal Rules Pertaining to Land Protection in Hungary
324-331Views:94Buildings in industry, mining, transportation and for personal and commercial activities cover increasingly more valuable agricultural land. The increase of sub-urbanization and vehicular traffic and the spread of malls and other kinds of investments are causing serious harm for not only to human society, but to a whole national economy as well.
The law on agricultural land (1994:LV) contains legal rules for the preservation, use and classification of agricultural land. These rules define the temporary or permanent use of land for agricultural and non-agricultural purposes; the scale of the land-protection fee and the rules of the process on cases in which land is used for non-agricultural purposes without the consent of the land registry. In the field of land classification, the law prescribes the regulations which are to be followed in order to define the net income of agricultural land in Golden Crowns.
Hungarian land protection rules are unique in the European Union, because only few member-states have similar laws to ours. Community law does not regulate the member states, except in the case of land classification, because this is the basis of the tax paid on the agricultural lands, but even here, there are differences among the states.
