The document discusses map scripting and styling. It introduces Mapstraction, an open source JavaScript library that provides a unified API for multiple web mapping APIs like Google Maps, Bing Maps, OpenLayers and others. This allows developers to write one set of map scripts that work across many different mapping backends. It also introduces MapBox and TileMill, which allow developers to host and style their own map tiles, giving them more control over maps compared to Google Maps.
