“…Also, he made first attempt to define neogeography [2] This definition shed light on the evolution of geospatial products, i.e. provide typology of the geospatial approaches [4]. There are two fundamental factors of limitations of visual perception and errors in decision making for any kind of visualization: 1) scale dependency, or lack of ability to interactive and seamless changing of scale by user, and 2) projection dependency, or lack of ability to interactive and seamless changing of direction of sight by user.…”

Emerging of Google Earth in 2005 was perceived as significant achievements in geospatial sciences and bring into focus of mass attention the concept of Digital Earth, manifested seven years before by ex-vice-president of USA Al Gore. Nevertheless, scientific origins of Digital Earth and its relations with cartography still unclear. We investigate both problems and propose the vison of Digital Earth as a quantum leap in cartography method, or scientific revolution in the terms of Thomas Kuhn. Proposed vision of Digital Earth and extended classification of cartography methods, as well as its interdisciplinary impact, are explained and discussed.

“…Such an environment [5,9,10] has two properties: 1) threedimensionality, or the ability to view it from any direction of sight, and 2) scale-independency, or the ability to study the situation from any distance (or at any scale) within a certain dynamic range [8]. Later it was shown that new opportunities are achieved by eliminating the use of conventional cartographic signs in the representation of geospatial contextnow their role is performed by images of the earth's surface, the so-called remote sensing data [6]. This provides a unique opportunity to store in the new geospatial "container" any information at all (for example, maps, texts, etc.…”

The paper considers the question of bringing the existing set of laws, regulatory and legislative documents in line with the Digital Earth - new and promising universal and global environment for the information integration on all possible scales simultaneously. Existing of 4 possible geovisualization methods is stated, typology of geovisualization methods is proposed and discussed. A practical approach for determining the belonging of visualization to a particular type, based on the use of diagrams "angle-range", is proposed. Concept of 3D-documents within Digital Earth paradigm is unveiled and explained, brief history of the developing and adopting of this concept is described, the prospects of the future evolution of 3D-documents are considered briefly.

“…Digital Earth is a virtual representation of Earth constructed based on a reference spheroid (Eremchenko et al 2015;Guo et al 2020;Fukui et al 2021). It is primarily used to achieve 3D visualization of Earth's surface and overground space.…”

For the construction of a Glass Earth a 3D geological entity model needs to be loaded into a Digital Earth visualization engine to visualize the expressions of geological entities. Space expressed by a 3D geological entity model is formed by a research area that extends vertically to a certain depth range in a projected coordinate system. When a 3D geological entity model is loaded into Digital Earth, the model-bounding box is combined with the model’s central point to perform the transformation, which causes the boundaries of adjacent models to deviate from each other to various degrees. Moreover, gaps and overlaps form at the top and bottom of the models, respectively. In this study, based on analyses of elevation naturalization correction and Gaussian projection deformation characteristics, bounding box–based free-form deformation was used to realize the model transformation in the process of loading a complex 3D geological entity model. By establishing a parametric model and mapping its relationship to the object to be deformed, free-form deformation was used based on deformation error correction. In this way, deviations between 3D geological entity models loaded into Digital Earth can be reduced. Using practical project cases, 3D geological entity models located at the margin of a zone six degrees wide in longitude and their central regions were comparatively analyzed. The results show that the free-form deformation used in this study can effectively reduce deviation problems in models.
