Visual Hierarchies in 3D Cartography with vts-geospatial
The brave new world of 3D mapping has taken little notice of time-proven rules of cartography, as if arbitrary viewing angles could somehow obliterate the need to convey a clear hierarchy of features. In this talk we will show how the vector styling capabilities in vts-geospatial may be used to overcome that long-standing shortcoming. From the choice of a basemap through the definition of intellectual and visual hierarchies to the coding of visual style, we will show how to produce 3D maps which aspire not only to the aesthetical appeal but also to the information value of a real cartographic product.
vts-mapproxy - The 3D Geospatial Streaming Server
vts-mapproxy is an open-source, C++ based, high-performance 3D geospatial data streaming server. Features include dynamic TIN generation from GDAL-supported DEMs, CesiumJS terrain provisioning, WMTS tiles with on-the-fly CS conversion etc. Though Mapproxy has been developed as part of vts-geospatial, it may be deployed on its own or even in hybrid operational architectures. In this talk, we are going to walk you through the common deployment scenarios, provide a hands-on demonstration of server configuration, and bring you up to speed with this little-known tool.
