“…Based on that, we attempt to improve the mathematical model of heritage corridor landscape visual evaluation under the influence of surrounding urban environment through the quantization method of landscape visual attention-degree. Using visualization technology [4], we finally construct the dynamic tour system for the Grand Canal (Hangzhou section).…”

The traditional heritage corridor is considered as one strategy of regional heritage preservation, which is linked with urban green space system. However, as a largescale and linear urban public open space, heritage corridor landscape has a dynamic tour system that is closely linked with citizens' life and tourists visit experience. We introduced the concept of landscape visual attention-degree in the former related research. And then through the study of visual evaluation criteria of heritage corridor landscape and dynamic sightseeing features, we established a quantitative visual evaluation system influenced by multi-factor interactive model. Based on that, we take the Grand Canal (Hangzhou section) as an example, deepen at methodology level and practice at the operational level. On the one hand, we optimized heritage corridor landscape visual evaluation method under different movement modes by establishing a pairwise-comparison quantization scheme of landscape visual attention-degree, and also we improved a quantitative visual evaluation model under the influence of multi-factor. On the other hand, through analysing the urban environment around the heritage corridor and combining computer visualization technology, we construct the dynamic tour system, so as to enhance the overall landscape visual perception and landscape image of the heritage corridor.

“…A lot of principles come from theorems of mathematical analysis, mathematical statistics, work with bulk data, etc. With the help of spatial analysis, for instance, suitable locations for constructions are looked for, movement of people and goods is watched, and trends of development of objects and especially phenomena are determined (Svatonova & Rybansky, 2014).…”

Cartography and geoinformatics are technical-based fields which deal with modelling and visualization of landscape in the form of a map. The theoretical foundation is necessary to obtain during study of cartography and geoinformatics based mainly on mathematics. For the given subjects, mathematics is necessary for understanding of many procedures that are connected to modelling of the Earth as a celestial body, to ways of its projection into a plane, to methods and procedures of modelling of landscape and phenomena in society and visualization of these models in the form of electronic as well as classic paper maps. Not only general mathematics, but also its extension of differential geometry of curves and surfaces, ways of approximation of lines and surfaces of functional surfaces, mathematical statistics and multi-criterial analyses seem to be suitable and necessary. Underestimation of the significance of mathematical education in cartography and geoinformatics is inappropriate and lowers competence of cartographers and professionals in geographic information science and technology to solve problems. .

“…Applications like Google Earth or Virtual Earth have generated a considerable expansion of the third dimension in the geoinformatics domain and geography. The use of 3D visualization in areas of emergency planning, crisis management, noise mapping, urban planning, geographical education or virtual tourism is growing (Biljecki et al, 2015;Lin et al, 2015;Svatonova and Rybansky, 2014;Herman and Reznik, 2013;Popelka and Brychtova, 2013;Bandrova et al, 2012;Konecny and Stanek, 2010). Wood et al (2005) present that most 3D geovisualization approaches are technology driven rather than theory driven.…”

Commission VI, WG VI/4 KEY WORDS: 3D visualization, interaction, human computer interaction, user issues, touch screen. ABSTRACT:The use of both 3D visualization and devices with touch displays is increasing. In this paper, we focused on the Web technologies for 3D visualization of spatial data and its interaction via touch screen gestures. At the first stage, we compared the support of touch interaction in selected JavaScript libraries on different hardware (desktop PCs with touch screens, tablets, and smartphones) and software platforms. Afterward, we realized simple empiric test (within-subject design, 6 participants, 2 simple tasks, LCD touch monitor Acer and digital terrain models as stimuli) focusing on the ability of users to solve simple spatial tasks via touch screens. An in-house testing web tool was developed and used based on JavaScript, PHP, and X3DOM languages and Hammer.js libraries. The correctness of answers, speed of users' performances, used gestures, and a simple gesture metric was recorded and analysed. Preliminary results revealed that the pan gesture is most frequently used by test participants and it is also supported by the majority of 3D libraries. Possible gesture metrics and future developments including the interpersonal differences are discussed in the conclusion.
