Add imagery for offline use

[AsafEvenPaz]

Hi,

I wanted to know if it is possible to add the imagery basemap (as a mobile scene package or something else) and then take it offline in ArcGIS Earth.

Hi,

The easiest way is to use the Download Map option on the Map Tab or Tile Package Kreator (second link).

https://pro.arcgis.com/en/pro-app/help/projects/take-a-map-offline.htm#ESRI_SECTION1_50BF87B39D1046E...

This will create a tile package. Since the tile package will be in Web Mercator you will need to add that to a basemap and then to a new global scene in order for the Create Mobile Scene Package tool to set the Scene's coordinate system as Web Mercator.

@Andrew Thanks for the response. I am trying to use the "Download Map" option in Pro but the tile package which gets created does not show tiles beyond the 1:5000 scale even if I set the "Max scale for Tile Layers" to 1: 142 (the default). Any way to fix this? I know this is slightly off topic but without maximum available resolution the 3D scene I am creating will not be useful...

Hi,

Are you trying to take a large area offline? Based on the help it says "Each tile layer has a maximum number of tiles that can be taken offline. If your map covers a large area, the maximum tile limit will be reached at a given scale." so it appears that you are reaching a limit here and one way to verify is zooming in to a smaller area and see if you can get more tiles. I'll reach out to the team that implemented this to confirm.

thanks,

Andrew

Yes - I am trying to take it offline. I tried zooming in on a smaller area but did not see any change. Also, there is no error message to indicate there is a problem...

Hi,

It's probably best to clarify larger vs smaller...for me I zoomed in on a neighborhood using the World Topographic basemap and was able to take all zoom levels offline. Which basemap are you using? I reached out to the team in charge of this and am still waiting to hear back.

thanks,

Andrew

The area is about 7 sq km. I am trying to use the imagery basemap

[Andrew--Johnson]

Hi,

Thanks for those details. I heard back from our Content Management Team and it looks like for the World Imagery there is a maximum export tile request of 150,000 tiles. This is specified here https://www.arcgis.com/home/item.html?id=226d23f076da478bba4589e7eae95952

They did say that they are looking to add better messaging/error handling when the max tile count is reached. In your case it does seem to me all of it should download for 7sq km. If you want to create a bookmark at the location you are downloading the map and then send me the bookmark I can try on my end. Otherwise the only other recommendation I have is to use an alternative imagery source for example NAIP imagery https://datagateway.nrcs.usda.gov/GDGHome_DirectDownLoad.aspx

Andrew,

Here is the bookmark - please try on your end and let me know.

Hi,

I was able to create the tpk with all 18 levels.
