Comment on #1 OSMnx and Treepedia

> I took a first try in generating a greenview index map for a smaller area. To do that, I used OSMnx to extract a graph from a location and then saved the shapefile (in what I think was the correct projection). All steps run ok, but I noticed I was getting always the same value of GVI (-166,667) for all coordinates which indicated immediately that there was something wrong with my input file.

You should check if you are using your own Google Street View image API key (<https://developers.google.com/maps/documentation/streetview/usage-and-billing|https://developers.google.com/maps/documentation/streetview/usage-and-billing>). The former key is expired because Google changed its pricing policy. The reason why we set negative value is used to tell users that the result is invalid. If you have too many invalid results, that means your images may not be properly downloaded.
