Export World Imagery for offline use

Hello,

I am currently trying to export World Imagery for offline use, as I do not always have internet in the area I'm working. I would like to use the World Imagery (for Export) to create a tile package of my area of interest, a small coastal area of ~20 sq-km in South America. In all of my searching of the vast resources of the ESRI community, I have not yet succeeded to have an imagery file from which to work offline.

When I accessed the World Imagery (for Export) on the menu of ESRI tiled basemaps, and selected "Open for ArcGIS Desktop" from the Open pulldown menu, I was prompted to save as an ArcGIS Portal Item (.pitem), which I did. When I then double-clicked on the file to open it in Desktop, I got a spinning wheel cursor for a few seconds, and then... nothing. Nothing appeared in the map, nothing happened. The .pitem file (a format which I am not familiar with, pardon me) is not visible in the ArcMap Catalog.

If anyone could help me in the objective of creating and accessing an imagery file to be used offline as a basemap, I would really appreciate the help. It is the first step in carrying out my work, and I hope there is a solution!

Thank you!

Whitney,

You would get the errors of "layer has unknown spatial reference’ when you have a layer in the table of contents which does not have a projection assigned to it. Kindly check your layers in the map to see if there’s any layer which has no spatial reference assigned to it. If so, please assign a spatial reference to that particular layer.

World Imagery basemap you are working with uses Web Mercator Auxiliary Sphere (WKID 102100) as the coordinate system.

All layers in the Runtime content will be projected into the spatial reference of the map document's data frame. If a basemap layer is included, the layers will be projected to the spatial reference of the basemap layer's tiling scheme.

Here’s a link for your reference on creating Runtime Content:

I hope this helps!

Hi Whitney,

Thank you Rakesh, that is a helpful thread.

The problem I am running into with creating runtime content is that the spatial reference for the World Imagery basemap seems to be throwing a wrench in things. I get errors of "layer has unknown spatial reference," "layer's spatial reference differs from runtime content's target spatial reference," and "the data frame's spatial reference is not the same as the Basemap layer's tiling scheme." I'm not sure how to address this. Information in the Basemap properties is fairly limited, and includes no information on spatial reference.

Thank you for your help and patience!

Oh great! I love when solutions are that simple. Thanks!

Unfortunately, when I run it, it starts to create tiles for the basemap, working for some time through 19 tiles, and then at the very end (after the 19th), I get a message that tells me, "An unexpected error has occurred when creating the package. Check your settings and try again." Hmph. The problem-solving search continues...

Thanks for all the info!
