What are some best practices for creating a basemap with a custom tiling scheme? (Desktop and AGOL)

Question asked by landscaper on Jun 23, 2015

Title says it all, but I also have some background info / requirements:

 

  • All of my data in the following state plane coordinate system: NAD_1983_HARN_StatePlane_California_V_FIPS_0405_Feet
  • I publish from ArcMap or Pro.
  • I have reference data and rasters that I would like to be able to switch out for use as a basemap
  • I need to be able to zoom past 1:1128 (level 20)
  • I want a smooth performing map

 

Related question: What happens if I add data from one coordinate system like WGS_1984_Web_Mercator_Auxiliary_Sphere on top of my basemap that uses a custom tiling scheme that uses NAD_1983_HARN_StatePlane_California_V_FIPS_0405_Feet? Would the proper projecting on-the-fly occur in the ArcGIS.com map viewer?

 

FYI - I am just looking for some best practices. So far I have the following info:

"When you use your own basemap, your map uses the projection of that basemap instead of Web Mercator, the projection of the map viewer."

from: "Use your own basemap" - https://doc.arcgis.com/en/arcgis-online/create-maps/choose-basemap.htm#ESRI_SECTION1_5EA1869127A74F19A6FA105A9441766E

 

"The map viewer can't display layers in a map without a working basemap because the basemap establishes the coordinate system of the map. "
