Three-dimensional (3D) building models are essential for urban planning, spatial analysis, and virtual simulations. However, most reconstruction methods based on Airborne LiDAR Scanning (ALS) rely primarily on rooftop information, often resulting in distorted footprints and the omission of façade semantics such as …

Schematic maps are widely used to represent transportation networks. Researchers have applied this idea to road maps and investigated their effectiveness and performance. However, studies have focused on car navigation tasks, whereas research on the impact of schematic representations of road maps …

Studies regarding vegetation phenology variations along the urban-rural gradients (URGs) that rely on the binary classification of “urban-rural” cannot reveal fine-scale spatial heterogeneity. In this study, we selected the urban area of Dalian as an example and combined the urban spatial structure …

Schematic maps have widely been used for representing transport networks. In the schematization process, preserving the relative position of nodes and the relative length of segments are considered highly important for constructing spatial cognition. Some researchers have regarded these as general principles …

Pedestrians’ route choice is critical for several purposes, while deliberately changing map representations can influence map users’ route choice. Simplifying routes’ geometric shapes is one way to achieve this. However, the other geometric characteristics of routes (e.g., the relative distance of different …

Landmark buildings are salient features for spatial cognition on maps. Distinctive outlines are the major visual characteristics that separate landmark buildings from their surrounding environments. The automatic symbolization of landmark outlines facilitates recognition and map production. As users often recognize landmarks by …

Knowing the distributions and changes in global wetlands and their conversion to other land cover types could facilitate our understanding of wetland development, causes of variations, and decision-making for restoration and protection. This study aimed to comprehensively analyze the changes in wetland …

A compact construction for nonbinary low-density parity-check (LDPC) codes over GF(q) (q>2) using permutation polynomials (PPs) is proposed in this paper. Following the previous compact construction for binary LDPC codes using quadratic permutation polynomials (QPPs) over integer rings, a QPP whose coefficients …
