In one of the Regulations of the Ministry of Science and Higher Education one can find an appendix which defines standards of education for the Geodesy and Cartography of the first level of studies, also in terms of computer programming. The author of the article has for many years combined teaching programming with engineering practice and he has no doubts that it is essential to teach future engineer surveyors how to write computer programs. However, the advisability of teaching programming sometimes raises concerns both among some students and academic teachers. The method of solving problems which was used during the process of numerical map modernization, described in the article, is in the author's opinion a strong argument in favour of advisability of computer programming education . The company run by the author has performed works which aim was to improve the cartometricity of a numerical map which contained selected objects of geospatial data. Meeting a deadline of the works would have been impossible without some tiny applications facilitating unnecessary works. After the works had been completed, it turned out that the applications shortened the time of making the modernization by 1/3 and what ...
Digital maps created in the process of digitising of cartographic materials contain a lot of topological errors. The sources of these errors are: the qualities of the digitising method and the operator's mistakes. Digital maps which are not cor-rect in terms of topology cannot be used in the vector data processing systems. The special case of topological errors of digital maps is the disagreement of the course of plot boundaries and the functional grounds boundaries. The authors have cre-ated and implemented an algorithm which corrects such errors and which is based on the correction of the course of functional grounds boundaries in the area sur-rounding a given segment of the plot boundary. The program which uses the above algorithm is highly efficient. ...
LPIS (Land Parcel Identyfication System) is an informative system enabling the implementation of unequivocal, in the scale of the country, identyfication of agricultural lands, which is used among others to control conformity of the actual surface of crops with the declared one. During the process of consulting about the project of the computer program supporting the works connected with the execution of LPIS 86 and LPIS GIS tasks, a number of problems were encountered resulting from the character of the tasks as well as the amount of information to be processed.Specificity of works which were to be done made the contractors seek after computer solutions effectively assisting the accomplishment of all tasks. The analysis consisting in comparing the scope of works with the possibilities of the programs belonging to the companies and the programs available on the market proved that the fastest and the most efficient solution would be supplementing the programs with functions designed specially to the needs of LPIS. The technology recommended for the tasks execution along with specially developed computer program made it possible to complete the full range of the tasks and meet tight deadlines.
