Arctic Web Map (AWM) is an Arctic-specific web mapping tool allowing researchers and developers to customize map projections for scientifically accurate visualization and analysis, a function that is critical for arctic research but not easy to do with existing web mapping platforms. It provides a visually appealing tool for education and outreach to a wider audience. Arctic Web Map has two components: An Arctic-focused tile server offering mapping tiles, and a Leaflet-based client library. By providing tiles in multiple Arctic projections, data can be more accurately visualized compared to most Mercator projected map tiles. The open source client library, PolarMap.js, is designed to be easy to use and easy to extend. It does this by providing a simple wrapper for building a typical Leaflet map, and also by providing base classes that can be customized to build a web map for your specific situation. This presentation will present and demonstrate the AWM and PolarMap.js and some real-world applications will also be discussed and demonstrated.
