Minimum and maximum angle of image in serch using API

1

Hi all!

I’m trying top play with Mapillary API.

In GET /search/im/close …

https://a.mapillary.com/#get-searchimclose

… that gets images close to a certain point defined by longitude, latitude, max angle, min angle and a radius in meters, for example …

https://a.mapillary.com/v2/search/im/close?client_id=<CLIENT_ID>&lat=55.874973779667876&limit=1&lon=12.981805801391602&min_ca=140&max_ca=190

what’s the meaning of min_ca and max_ca parameters? 140 and 190 are degrees but … concerning what? To the north respect the point? Is there somewhere some picture or details that explain this stuff?

Thank you very much in advance!!

Hi,

Awesome you are using the API. 0 refers to North then clockwise ending up with 360.

Let me know if you have any more questions.

Hi Johan,

about this I’ve tried, starting from a point, to search images “at East” using this request …

https://a.mapillary.com/v2/search/im/geojson/close?client_id=<my_code>&lat=44.91088&lon=7.67424&limit=1&min_ca=45&max_ca=135&distance=10

… and it works fine.

But when I try to search images “at North” using this request …

 https://a.mapillary.com/v2/search/im/geojson/close?client_id=<my_code>&lat=44.91088&lon=7.67424&limit=1&min_ca=315&max_ca=45&distance=10

… no data is returned.

I think that probably is something about “min_ca” and “max_ca” parameters in the request … any suggestion about this?

Thank you very much in advance!!!
