Many small solar system bodies such as asteroids or satellites have irregular shapes, often approximated by the reference surface of a triaxial ellipsoid. Map projections for ellipsoid are needed to present incoming data in form maps. In this paper formulae equal-area cylindrical and azimuthal were derived practically implemented first time using an example asteroid 253 Mathilde. This is final series papers devoted all main classes Before this, authors obtained equidistant along meridians...

The 28th International Cartographic Conference ICC 2017 was held in Washington, DC July 2017. conference is a significant event the world of cartography setting path development for next 2 years. 40 topics were offered to participants accordance with which they had make oral presentations or posters and submit articles. It should be noted trend expand topics. For example, geospatial technologies added section “Education training”; coordinate systems, transformations conversions “Map...

In our previous works, we described the projections that make it possible to construct maps of celestial bodies in planetary scale – azimuthal and cylindrical different distortion classes. However, for regions middle latitudes, is advisable use a conic projection, which has not been developed previously. this investigation, describe development three triaxial ellipsoid: projection with true along meridians, an equal-area quasi-conformal projection. The close conformal neighbourhood each...

A multiscale series of soil-landscape maps is regarded as a system all scales, which are adjusted in relation to geographical base and thematic content. Legends the based on hierarchical classification. The methodological basis for creation concept “natural landscape” defined using systems approach. Soil-landscape vertical structure landscapes properties their elements – rocks, air, water, organisms, soils. Technology creating GIS environment includes bringing primary coordinate system;...

Historically the conformal projections have been used for mapping not only Earth, but other celestial bodies as well. Their application enables preserving shape of relief features on maps, which is extremely important various analyses bodies’ surfaces. For many small Solar system International Astronomical Union recommends to apply a triaxial ellipsoid reference surface. But if surfaces sphere and an revolution already exist, obtaining these will be significantly complicated, task still...

The purpose of this study is to show that some coordinate systems previously described as isometric are in fact not isometric, and a consequence, map projections derived from them do the expected characteristics, especially conformality. Definitions methods mathematical theory surfaces used. article discusses two specifying on surface triaxial ellipsoid, erroneously called isometric. A consistent each based initial definition coordinates showed first method, corresponding system orthogonal,...

Abstract. Different distortion classes of the azimuthal and cylindrical projections triaxial ellipsoid have been considered in our previous works. These make it possible to construct maps celestial bodies planetary scale. However, for regions middle latitudes is advisable use a conic projection which was not developed until now. In this investigation we describe development three ellipsoid: with true scale along meridians, an equal-area quasi-conformal projection. derivation elliptical cone...

ПРОБЛЕМЫ МАТЕМАТИЧЕСКОЙ КАРТОГРАФИИ В ГИС АННОТАЦИЯБольшинство современных карт создаётся с использованием программного обеспечения ГИС.Описание проекции, в которой проектируется карта, содержится библиотеке PROJ.Эту библиотеку используют все популярные среди картографов ГИСпакеты.К сожалению, отсутствуют проекции советских карт, параметры которых отличаются от стандартно задаваемых.Привязка и трансформирование картографических материалов по множеству опорных точек приводит к...

The Commission on Map Projections (CoMP) of the International Cartographic Association (ICA) was chartered and began aсting in 2003. has been active promoting distributing map projections research, education, knowledge through its individual members, conferences workshops ICA. Among developments CoMP there are published papers workshops, conference sessions at Conferences, other international cartography geoinformation. developed maintained a public website with tutorial information...

The authors discuss various problems that might occur in the process of integrating data for celestial bodies obtained from many sources. may be combined and result this combination is presented a unified form which initial stage creating bodies’ maps especially those Solar system’s small ones. This should realized even before starting map compilation. Data integration divided into three groups
