Development of methods and technologies creation of digital large- and medium-scale soil maps using GIS technology
The possibilities of creating soil maps of large and medium scale directly in the digital environment are considered. We elaborated an algorithm of creating digital soil maps, according to which digital maps in scale 1 : 50 000 and 1 : 200 000 on the key area of Kletsk are made. A distinctive feature of the proposed algorithm of creating maps from the other existing guidelines is a partial automation of processes of both geometric and classification generalization. The comparison of created digital and existing soil maps analog in 8 parameters of assessing the quality of generalization is given. As a result, it was found that the development of methodological aspects of creating digital soil maps is inextricably linked with the integration of GIS technology at all stages of cards, and digital large- and medium-scale soil maps created by the developed algorithm exceed their paper counterparts on all the indicators of measuring the quality of cards and to the maximum extent characterise a real topsoil territory
