DEVELOPMENT OF PRACTICAL RECOMMENDATIONS FOR CREATING ELECTRONIC FIELD MAPS USING PROGRAMS BASED ON THE ANDROID OPERATING SYSTEM
Electronic maps are necessary to measure the area of fields and create a digital environment with which the rest of the components of precision agriculture work. For practical implementation, the method of rendering fields using special programs based on the ANDROID operating system was chosen. The programs «GPS Area» from News Marathon Ltd, «Field navigator» from Farmis and «Field Bee» from e Farmer BV were determined to be the most optimal in terms of functionality. To create electronic maps using the method of rendering programs based on the ANDROID operating system, it is better to use more complex parallel driving systems which allow not only to save fields, but also have the functions of exporting maps, transferring, and changing units of measurement. These systems allow combining the functions of rendering and detouring fields, as well as connect an external GPS antenna to increase the accuracy of measurements. Herewith, it was found out that the course indicator programs do not render or create electronic maps, but only serve to draw parallel lines and trackers onto the limitless virtual field of the application. Numerical analysis of the optimal selection criterion showed that the most effective program was "Field navigator" with the selection criterion Z = 5,01. Based on the research of software on the ANDROID operating system, practical recommendations have been developed.
