billbillbilly/streetscape ? reverse-engineered prompt

Build me an R package that helps me find and download street view images from Mapillary, then analyze what’s in the scene and show it in a useful way.

I want to be able to search by point, radius, bounding box, or road area, then get back the image metadata and image links. It should also let me pull the semantic mask, break down the visible features, and calculate a green view score for how much greenery is in the image. Please include a simple map preview so I can see the results before downloading or analyzing.

It would also be great if the package can generate Qualtrics survey text files from a set of street view images, including both rating questions and pairwise comparison surveys. Add a few example datasets, clear help files, and small tests so the main functions are easy to understand and use. If you need to check current API or package docs online, go ahead.
