Chapter 7:<\/strong><\/p>\n

3D web maps are called web scenes or 3D scenes. Photo-realistic scenes try to make objects look as accurate as possible. Cartographic are often used for display information like population density and zoning laws.<\/p>\n

Surfaces: continuous measurement, typically elevation, often referred to as digital elevation model (DEM), digital terrain model (DTM)- bare ground, or digital surface model (DSM)- ground surface and objects on it.<\/p>\n

Features: On, above, or below surfaces. May be 2D or 3D. Operational layers of the 3D map.<\/p>\n

Textures: covers of 3D features<\/p>\n

Atmospheric effects: lighting, fog, etc<\/p>\n

3D object scene layers: represent and visualize 3D objects<\/p>\n

Building scene layers: shows complex digital models of buildings that you can interact with – materials, properties, locations.<\/p>\n

Point scene layers: cached point scene layers are thinned so that certain details are only visible at certain zoom levels to display large amounts of point data that wold take too long as a point feature layer<\/p>\n

Voxel scene layers: multidimensional spatial and temporal data in 3D volumetric visualization<\/p>\n

I struggled for a minute to find where Elevation mode and Absolute Height could be configured in the Style pane because they are now under Layer Properties rather than Layer Style. Once I figured out where those were, figuring out where everything else is was pretty intuitive.<\/p>\n

My computer is really struggling with the 3D scenes, especially the last one since someone has put a giant helicopter in the publicly edited scene.<\/p>\n

Application:<\/strong><\/p>\n

A potential application of chapter 7 is to create a tour of where I grew up, since I’d like to show my friends, but it’s too far away for me to bring them there in person. I would use the OpenStreetMap Style 3D Basemap and add paths and way-points that show pictures that I have of some of my favorite places.<\/p>\n","protected":false},"excerpt":{"rendered":"
