Need to get a model fast and don’t have any data (especially imagery)
Then the model builder preview is here to help.
Based on 150 sq meters the datasets consist of :
“Terrain data for the United States and its territories uses USGS 10- and 30 metre DEMs from the National Elevation Dataset (NED). The rest of the globe (between -60° and +60° latitude) uses SRTM 90m DEM data, processed by CIAT-CSI”
“Satellite imagery from Microsoft® Bing Maps is draped over the model terrain.”
“OpenStreetMap's Highway and Railway datasets are readily available. They'll be used to create roads and railway features in the model.”
“The building data is also from the OpenStreetMap dataset”
Within about 15 minutes I get this.
In most cases you probably just need some context to the area of interest that you are wanting to work on, so it can give you a flying start and the chance to swap with higher quality data as you need it.
Happy model building !
