Abstract:
A new approach (method and algorithm) to assessing the relative positions of vector geospatial objects of arbitrary geometry in geoinformation solutions is proposed. The approach is based on the concept of spatial domains and interpolation of attribute parameter values, which together allow analyzing intersections even for geospatial objects with an irregular and sparse structure, such as isolines and point layers. To formalize the proposed approach, a mathematical model is proposed that characterizes the process of forming intermediate geospatial primitives and assessing their attributes using interpolation. To assess the performance of the proposed solution, a research prototype of a web application based on Python and GeoPandas was developed. The computational experiments showed the effectiveness of the proposed approach both with respect to the accuracy of the corresponding values and in terms of the performance of the final web application.

Keywords:
geographic information systems, spatial analysis, vector data, computational geometry, interpolation, image processing algorithms.
