PlaceMaker is a plugin (extension) for SketchUp that allows you to import High resolution Aerials, 3D buildings, parametric 3D roads and walks and even bodies of water and trees.
It will save you hours, if not days, of work and create instant cities from across the world.
PlaceMaker imports data from a variety of online sources including OpenStreetMap, DigitalGlobe, and Nearmap.
Almost all locations have coverage for High-resolution aerial imagery (DigitalGlobe) and roads. Aerials and imported objects can also be merged directly onto terrain.
Many locations have 3D buildings, walking paths and bodies of water (ocean, lakes, streams). On occasion the OSM data may also include some trees and vegetation.
