Spatial multi-criteria evaluation in 3D context: suitability analysis of urban vertical development Cartography and Geographic Information Science (IF 2.429) Pub Date : 2020-12-03 Kendra Munn, S. Dragićević
ABSTRACT Urban densification is often seen as a process that aims to limit the negative environmental impacts of urban sprawl in rapidly growing cities by prioritizing planning policies stimulating vertical growth (or high-rise development) over expansion along the urban fringe. Densification of major Canadian urban areas has led to the proliferation of high-rises with an increasing proportion of residents

Aggregating land-use polygons considering line features as separating map elements Cartography and Geographic Information Science (IF 2.429) Pub Date : 2021-01-26 Sven Gedicke, Johannes Oehrlein, Jan-Henrik Haunert
ABSTRACT Map generalization is the process of deriving small-scale target maps from a large-scale source map or database while preserving valuable information. In this paper we focus on topographic data, in particular areas of different land-use classes and line features representing the road network. When reducing the map scale, some areas need to be merged to larger composite regions. This process

Local terrain modification method considering physical feature constraints for vector elements Cartography and Geographic Information Science (IF 2.429) Pub Date : 2020-07-06 Jiangfeng She, Junyan Liu, Junzhong Tan, JiWei Dong, Wang Biao
ABSTRACT Many studies have been focused on rendering 2D vector elements on 3D terrain, and a series of algorithms have been proposed. Most of these algorithms struggle to provide a seamless overlay between vector elements and an irregular terrain surface. Despite their importance, the physical characteristics of vector elements are often ignored, which distorts the surface of vector elements. For example
