TL;DR: This article theorizes on how Web Mercator came to be widely used for online maps and what this might mean in terms of data display, technical aspects of map generation and distribution, design, and cognition of spatial patterns.
Abstract: Online interactive maps have become a popular means of communicating with spatial data. In most online mapping systems, Web Mercator has become the dominant projection. While the Mercator projection has a long history of discussion about its inappropriateness for general-purpose mapping, particularly at the global scale, and seems to have been virtually phased out for general-purpose global-scale print maps, it has seen a resurgence in popularity in Web Mercator form. This article theorizes on how Web Mercator came to be widely used for online maps and what this might mean in terms of data display, technical aspects of map generation and distribution, design, and cognition of spatial patterns. The authors emphasize details of where the projection excels and where it does not, as well as some of its advantages and disadvantages for cartographic communication, and conclude with some research directions that may help to develop better solutions to the problem of projections for general-purpose, multi-scale Web mapping.
Resume: Les cartes interactives en ligne sont devenues un moyen populaire de communiquer au moyen de donnees spatiales. Dans la plupart des systemes de cartographie en ligne, la projection de Mercator sur le Web est devenue la projection dominante. La projection de Mercator souleve depuis longtemps des discussions sur son caractere inapproprie en cartographie generale, particulierement a l’echelle de la planete, et elle semble avoir a peu pres disparu des cartes imprimees a l’echelle mondiale d’usage general, mais on a constate un regain de popularite de la projection de Mercator sur le Web. Cet article presente une theorie sur la facon dont la projection de Mercator sur le Web s’est generalisee pour les cartes en ligne et sur ce que cela pourrait signifier pour l’affichage des donnees, les aspects techniques de la production et de la distribution de cartes, la conception et la cognition des tendances spatiales. Les auteurs mettent en evidence des details sur les aspects ou la projection excelle et sur ceux ou elle n’excelle pas, ainsi que certains de ses avantages et inconvenients pour la communication cartographique. Ils concluent par des pistes de recherche qui peuvent aider a trouver une meilleure solution au probleme des projections destinees a la cartographie generale a echelles multiples sur le Web.

TL;DR: Geo2xy converts geographic latitude and longitude to cartesian coordinates (x,y) using map projection transformations to produce high quality maps using standard Stata graph commands or with user-written commands like -spmap-.
Abstract: geo2xy converts geographic latitude and longitude to cartesian coordinates (x,y) using map projection transformations. The default projection is a Web Mercator, which is the same used by most web mapping applications (Google Maps, Bing Maps, etc.). As an option, -geo2xy- can generate Tissot's indicatrices (grid of circles) which, when overlaid on a map of the projected coordinates, help visualize the distortions of the chosen projection. With projected coordinates, high quality maps can be produced using standard Stata graph commands or with user-written commands like -spmap-.

TL;DR: In this article, the authors introduce Web Map Mashup (WMM) technology for the dissemination of Cartography: some technical/mapping issues connected to the interactive mapping software applications called WMM are introduced.
Abstract: Webmapping technology for the dissemination of Cartography: some considerations In this paper some technical/mapping issues connected to the interactive mapping software applications called Web Map Mashup (WMM) are introduced. There are many WMM strong points. They are intuitive, constantly updated and easily accessible by a pletora of different Internet connected devices. They are an extremely efficient tool in order to disseminate maps. WMM technology is introduced. Its Coordinate Reference System (CRS), known as “Web Mercator” is then deepened. Some Web Mercator CRS limitations are finally highlighted. La technologie webmapping pour la diffusion de la cartographie: quelques reflexions L’article presente quelques aspects techniques/cartographiques lies aux applications cartographiques interactives repandues aujourd’hui sur le Web (Web Map Mashup - WMM). Les points forts de ces applications sont nombreuses. Ils sont intuitifs, de plus en plus dans l’evolution technique, visible par une plethore de differents peripheriques connectes au reseau. Ils sont un outil tres efficace pour la diffusion des cartes. L’article introduite aussi la technologie que permet le fonctionnement de WMM. Il est ensuite approfondi le systeme de coordonnees utilise par ce type d’application (connue sous le nom “Web Mercator”, mettant en lumiere certaines limites.

TL;DR: Experimental result shows that algorithm has effectively solved the problem that Web Mercator map cannot be applied to client side / server mode.
Abstract: This paper aims at the problem that the third party application program interface of Mercator projection map only supports for browser/server mode when it is applied to system development of geographical information, adopting transformation of Mercator projection formula and combining with data fragment technology, putting forward an algorithm that Mercator projection map is applied to client side / server mode by taking Google map as example. Experimental result shows that algorithm has effectively solved the problem that Web Mercator map cannot be applied to client side / server mode.
