Hi James,

 

Thanks a lot for your information, also I want to ask you if you have a method or a threshold to define the numbers of coordinates necessary to create the polygon. I mean, for an specific area why to use 100 geographical coordinatesand not 1000.

 

Thanks in advance jamesdales

Hi Edwardo

 

I would always suggest to use the minimum amount of coordinates possible, as the fewer you use, the faster performance will be. There will always be a compromise between showing enough detail vs speed. It's the same with the Power BI shape map.

 

Also you'll hit the maximum length of a field in PowerQuery which is 32,766 characters, so beyond that you'll need to split the WKT shapes and then concatenate them using DAX in the data model.
