I’m finding the default sketchup aerial photos very poor quality and the Nearmap coverage isn’t great in my area (I also tried Placemaker but that wasn’t very useful).
In New Zealand, we have very high quality (and free) aerial photos and such, courtesy of the government and our space program.
Could we import this using a customised SketchUp extension? There’s info about APIs and things I don’t understand.
“WGS84 Web Mercator Quad (EPSG:3857)” sounds promising.
This also includes some fantastic resources via OpenTopography and other datasets (high-resolution contours & lidar points/mesh, building outlines, streets (with kerbs and footpaths), watercourse, soil, etc). It’s all free or “creative commons” licensed.
I have a hard time figuring out an efficient and accurate way to import this sort of GIS/topo data. Is there a trick to it?
There is no trick, it’s hard work. We have a simular system (PDOK) you download a massive zip file, have to install tons of programs, select what you want convert into shape files and then import them.
That’s only the topo part.
You have to be a programmer to like these kind of workflows.
They use CityJson in our parts, here’s a list of software(plugins)
I did a test where I found an area not covered by Nearmap, and I did an add location with Digital Globe, then replaced the center part with an image from that web page. There isn’t much differences in quality. The attached SKP shows the modified image, but also the original Digital Globe image.
