ISExport widget : getUTMZones for non-projectable to Mercator coordinate system #27

Closed Biboba closed 6 years ago

Biboba commented 6 years ago

Hello,

I noticed a typo in ISExport widget: https://github.com/Esri/WAB-Image-Services-Widgets/blob/529161c2764cdf6e9de9f0e098ce3e73ecda2dbb/imagery_widgets/ISExport/Widget.js#L290

Also when working with a coordinate system that cannot be projected to Mercator, the UTM zones computation code would fail as mapCenter would be undefined.

Hi Biboba,

Thank you for finding out this issue. I have made the required changes to make it work for all coordinate systems. If projection from one coordinate system to Mercator can be done client side, then client side function is called, otherwise a projection request is made (server). This way it will work for all coordinate systems. I am not merging your code as there are lot of other changes also.

Thank You.
