Looks like there’s been a lot of negative reviews, but i came here to do the same thing. I use sketchup to model shadows at specific locations around the globe for the purposes of ensuring proper solar energy collection for our clients. The Google satellite data was great for this. DigitalGlobe is completely unusable. I will be searching far and wide for a suitable replacement and will move to it as quickly as possible.
Sorry to be so negative, i really liked sketchup before this change. But I want to be honest, brutally so if necessary and i think it is necessary in this case. The DigitalGlobe imagery really is completely useless, unless of course you find value in a smorgasbord of pixelated brown and green hues.
