I have written an application that should measure the geodesic distance between the points of a polygon while creating the polygon (DistanceParameter) and when the polygone is finished the complete extent und area (both again geodesic) of the polygon should be computet. I've tried AreaAndLengthParameter, but there is no way to compute the geodesic area and extent with this function/parameter. Unfortunatly I haven't found another way to compute the geodesic area with a GeometryService.
Is there another API-function that I didn't notice to compute the geodesic area and extent of a geometry or do I have to compute it myself?
is there something like a roadmap for the JS API, with release dates and planed features?
There are some other features (i.e. snapping while editing geometries) I'd like to have in my application and it would be interesting if I have to code them myself or a future release would bring this features.
Unfortunately, there is no public available plan for the future. For snapping, yes, it's under consideration at the version 2.3. If you have any specific request for more functionalities, please let me know. Thanks for your feedback.
