Abstract
Most of existing web mapping systems usually use web Mercator projection. However, this is a
poor choice for geostatistical applications where distributions, densities, and relative areas are
important. Therefore, we propose a new web mapping system architecture, which provides
various map projections to meet the demands of users’ data. We first introduce client-side online
platform to present data in multiple map projections as well as additional functions to adapt polar
map orientation. Then we present a server-side component that pre-renders base maps in
different projections using distributed techniques to ease the time- and computation- intensive
tile rendering process. Also the server-side can parse the vector data users upload, while there are
thousands of map projections and we assume map users might lack the knowledge about map
projections (e.g., types, application, scale, etc.). We propose a server-side component that
recommends suitable SRID (Spatial Reference System Identifier) for input data.
