Cannot Display GeoJSON Coordinates in Proper Order for Bubble Type Layer in Map


Product Progress Kendo UI Map
Progress Kendo UI version Tested up to version 2017.2 504


I want to draw a bubble layer on a Kendo UI Map from the GeoJSON response. Although I receive the data in \[Longitude, Latitude\] format, when the data is bound to the Map, the Map handles it in a reversed \[latitude, longitude\] order.

Suggested Workarounds

The Kendo UI Map does not provide a built-in solution for achieving this behavior. However, you can still work around this issue by applying custom logic.

The Map accepts a [Latitude, Longitude] format for its locations field. When you receive the data in a reversed order, modify the array prior to the binding and use schema.parse to update the array.
