Best class for handling bounding boxes

[padmalcom]

Hi, we are coming from OSMdroid and work with the class bounding box which specifies an area defined by two lon/lat pairs. Now that we migrate to ESRI Maps SDK I wonder what class you propose for such a bounding box.

Hi @padmalcom,

Could you provide more details on which specific API calls or use case(s) you want to make/achieve with the ESRI Maps SDK?

I'm guessing you want to specify an area on the map, in which case you would likely want ot use Envelope.

Hi @GuntherHeppner, we are calling an api to get all points within an area - specifically on the area shown in the current mapView. I found Envelope but it does not use lat/lon but x/y and thus everything in me refuses to  use it since it is not geo specific. So I think we go with a custom data class. Nevertheless, thanks for your response.

An Envelope can handle lat/lon. It is used to specify a geographic area on the map, see the documentation on its base class Geometry. 

You might also want to take a look at MapView.screenToLocation, which allows you to convert a screen point to a geographic point in map coordinates. From these points you can then create an Envelope.
