Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth one can build a variety of visually pleasing, well-crafted maps with cartography or GIS software. GeoServer GeoCSS is a CSS inspired language allowing you to build maps without consuming fingertips in the process, while providing all the same abilities as SLD. In this talk, the presenters will show how they have built a world political map and a world geographic map based on Natural Earth, using CSS, and shared the results on GitHub. They will share with you how simple, compact styles can be used to prepare a multiscale map, including: * Leveraging CSS cascading. * Building styles that respond to scales in ways that go beyond simple scale dependencies. * Various types of labeling tricks (conflict resolution and label priority, controlling label density, label placement, typography, labels in various scripts, label shields and more). * Quickly controlling colors with LessCSS inspired functions. * Building symbology using GeoServer large set of well known marks.
