WGS 1984 Web Mercator

[GerryGarza]

Hi All,

I had the strangest request from one of my departments recently. They would like me to change the Protal for ArcGIS basemaps to a smiling US, so Canada does not look bigger. I showed them how they can use UTM 14 in ArcGIS Pro to get a smiling US, but did not explain that their data was being projected on the fly. Does anyone know if this can be done in Protal for ArcGIS Maps or does documentation exist explaining why this can't be done. Is there any documentation explaining why Esri adopted the Google WGS 1984 Web Mercator coordinate system?

Thank you in advance,

Gerry

Hi Gerry Garza‌,

A good start would be to read the following resources from a GIS analyst perspective: 

• Problem data sets do not line up when added to ArcMap 
• FAQ Projection Basics 

I believe some of the advantages of the WGS 1984 Web Mercator Coordinate System are North is up everywhere and the meridians are equally spaced vertical lines.
