“…It can be used to edit other octilinear layouts such as water or gas utility networks [20]. We also believe that our optimization framework is beneficial to generating metro tourist maps [12], [13], [14] because of its efficiency. Metro maps such as that of the New York City Subway 2 are designed to overlap street maps.…”

“…When linking stations and photos, their method minimizes the number of intersections between metro lines and connecting lines to enhance visual clarity. These researchers also ensured the placement of large annotation labels close to the corresponding stations to prevent occluding metro lines [13]. Given that many POI can exist in a city, the visualization easily results in visual clutter.…”

Abstract-Manual editing of a metro map is essential because many aesthetic and readability demands in map generation cannot be achieved by using a fully automatic method. In addition, a metro map should be updated when new metro lines are developed in a city. Considering that manually designing a metro map is time-consuming and requires expert skills, we present an interactive editing system that considers human knowledge and adjusts the layout to make it consistent with user expectations. In other words, only a few stations are controlled and the remaining stations are relocated by our system. Our system supports both curvilinear and octilinear layouts when creating metro maps. It solves an optimization problem, in which even spaces, route straightness, and maximum included angles at junctions are considered to obtain a curvilinear result. The system then rotates each edge to extend either vertically, horizontally, or diagonally while approximating the station positions provided by users to generate an octilinear layout. Experimental results, quantitative and qualitative evaluations, and user studies show that our editing system is easy to use and allows even non-professionals to design a metro map.

“…Wu et al demonstrate a sophisticated external labeling approach by reserving enough space for small images of metro stations in the maps [Wu et al 2013]. Fekete and Plaisant demonstrate an approach that displays labels in a cirular area around the cursor [Fekete and Plaisant 1999].…”

In this paper we analyze different layout algorithms that preserve relative directions in geo-referenced networks. This is an important criterion for many sensor networks such as the electric grid and other supply networks, because it enables the user to match the geographic setting with the drawing on the screen. Even today, the layouts of these networks are often created manually. This is due to the requirement that these layouts must respect geographic references but should still be easy to read and understand. The range of available automatic algorithms spans from general graph layouts over schematic maps to semi-realistic drawings. At first sight, schematics seem to be a promising compromise between geographic correctness and readability. The former property exploits the mental map of the user while the latter makes it easier for the user to learn about the network structure. We investigate different algorithms for such maps together with different visualization techniques. In particular, the group of octi-linear layouts is prominent in handcrafted subway maps. These algorithms have been used extensively to generate drawings for subway maps. Also known as Metro Map layouts, only horizontal, vertical and diagonal directions are allowed. This increases flexibility and makes the resulting layout look similar to the well-known subway maps of large cities. The key difference to general graph layout algorithms is that geographic relations are respected in terms of relative directions. However, it is not clear, whether this metaphor can be transferred from metro maps to other domains. We discuss applicability of these different approaches for geo-based networks in general with the electric grid as a use-case scenario

“…Several previous papers address these scenario on different kind of maps [5,12,9]. An alternative approach is to rearrange the drawing to avoid overlaps [18]. In contrast to this approach we do not change the layout as we do not want to disturb the view of the user.…”

The display of data related to graphical objects on a map is a well studied problem in cartography and several approaches have been published. Adapting the idea of boundary labeling using a focus region, we face the problem of emphasizing additional information and labels for objects within a focus region even when the region might be moving. We propose four different approaches that support effective solutions in various ways, and discuss advantages and drawbacks. Our algorithms regard the dynamic nature of the focus region to place the labels and preserve the mental map of the analyzed drawing. We demonstrate our methods by applying them to biological networks.
