Thanks for the reply, but this “use” part of the function documentation is quite clear to me. I successfully use it to query and harvest images via the API. My question relates to the geometry/trigonometry that sits behind the
&lookat= call. For reference I provide a sample cURL request as a code block in my R script:
res <-GET(paste0( "https://a.mapillary.com/v3/images/?",
My question is thus related not to the “how to use”, but rater to “how does it work” semantics. The example snippet I was expecting would be something including SIN/COSINE trigonometric functions to estimate angle between the image and the point being looked at and then comparing this for each image to some threshold angle range, after/before which the point would be deemed “invisible” from the location of the image.
Do you have an answer for this question?
