A while ago, Alan McConchie and Beth Schechter of Stamen held a presentation titled Anatomy of a Web Map at Maptime SF, a weekly map hack-night hosted at Stamen Design. The slides can be viewed at maptime.github.io/anatomy-of-a-web-map (allow some seconds for loading). Click through for a thorough refresher and some innovative web map technologies. Even if you are familiar with the topic, you might still learn something new: For me, such a new thing was UTFGrid.
In this year’s Swiss GeoSummit, Cédric Moullet of Swisstopo talked about similar topics in his presentation. Among others he featured a comparison of popular webmapping frameworks, the best-known being Leaflet and OpenLayers (he himself being an OpenLayers proponent). His slides can be seen here, enjoy.
