Hi, I'm just trying to get my head around the workflows for creating and downloading offline map areas in 10.8.1 and the Explorer app. I've prepared a test map and set the advanced options to use a vtpk that I've already sideloaded onto the device. I've then created a test area in the map which uses a raster tile package as the basemap. I did wonder why it created a tile package for the area when I've said to use the vtpk on the device but I guess this allows it to work where a different user may not have that specific basemap sideloaded. So I have my very small operational data package and then around 80mb of basemap. When I go to view the offline area in Explorer (iOS) I can see that the size of the package it wants to download is the 80mb rather than just the few hundred kb. If I click to download it gives me the impression that it is downloading the full 80mb (though it is difficult to tell because it does go pretty quickly via my relatively speedy broadband connection). Once downloaded it certainly looks as if it has downloaded the full 80mb of data including the basemap (which I don't actually want because I have my nice sideloaded version already on the device). If I pull down on the screen to refresh the details then the file size magically updates to exclude the basemap and just show the operational layers.  When I open the map area and start using it then it is correctly using the vtpk basemap from the device. My question is whether I've just been fooled into thinking that the basemap part of the package was downloaded or if it did go ahead and just download the whole thing, only disregarding the basemap part once it had checked that the sideloaded vtpk that it was expecting to see was actually there? It feels like it must be the former or it would surely defeat the purpose of having sideloaded the basemap, but if that is the case then would it be possible to indicate in the Explorer part of the workflow that it only needs to download the 495kb rather than the 80mb?  It would also potentially be useful if the Explorer interface indicated that the offline map area is configured to use a local basemap and even state the name of the package that it expects to use. Also showing the date of when the current downloaded data package (not the basemap) was produced would be useful. I appreciate these bits are more queries for Explorer rather than Enterprise. ...

I think I probably already know the answer to this but thought it might be useful sharing and possibly getting an update to the ArcGIS Enterprise documentation. I'm using ArcGIS Enterprise 10.8.1 and want to create polygon (not rectangle) map areas for an offline map. My map meets the requirements for taking data offline but if I have a vector tile package as my basemap then the polygon sketch tool is disabled in the create offline areas interface. If I switch the basemap to a raster tile package then the polygon sketch tool is enabled. I've done a bit of a trawl through the documentation and can't find any reference to this. Take web maps offline—Portal for ArcGIS | Documentation for ArcGIS Enterprise  Step 7 just says To draw a shape representing the map area, click one of the buttons on the   Sketch   toolbar. To draw a box around the area to take offline, click the   Sketch rectangular map area   button     and draw a box on the map. To draw a polygon to define the area you need to take offline, click the   Sketch polygon map area   button     and draw the polygon on the map. The equivalent ArcGIS Online documentation has a specific note about this in step 7 Take web maps offline—ArcGIS Online Help | Documentation  To draw a shape representing the map area, click one of the buttons on the   Sketch   toolbar. To draw a box around the area to take offline, click the   Sketch rectangular map area   button     and draw a box on the map. To draw a polygon to define the area you need to take offline, click the   Sketch polygon map area   button     and draw the polygon on the map. The map's basemap must be an   ArcGIS Online   hosted tile layer or a tile layer from an   ArcGIS Enterprise   10.7 or more recent release portal; otherwise, the   Sketch polygon map area   button will not be active. So can we assume that the same restrictions apply when working in Enterprise and would it be possible to get the documentation updated to reflect this? Is there any timescale when polygon areas will be supported with vector basemaps? Does the restriction still apply if the package is created without a basemap and relies on a map on the user's device instead? Regards Gareth PS I've just spotted this blog which I think confirms the restrictions, but still would be good to get in the docs. Define polygon offline map areas for Collector  ... View more

I've not really done anything with Image Services before so apologies if I'm missing something obvious here. I have a DTM layer in a file geodatabase which I'm publishing to ArcGIS Server 10.7.1 by right clicking in ArcCatalog and selecting Share as image service. For info we don't have the Image Server extension installed, but I don't think that matters as I'm not publishing a mosaic. The rest services end point shows the following details (which is what I would expect) single band floating point image. I can bring the layer into Portal and enable pop-ups in a web map so that it returns the elevation value for each pixel. This is all fine and as I want it to work except that the default symbology doesn't suit (I've tried changing that in the web map but it often seems to reset itself - maybe something I'm doing wrong, but not the focus of this question, for now at least).  So I have created a layer file with the symbology that I want to use - stretch, percent clip, colour ramp etc - and used ArcCatalog to share as an image service.  This meant that the layer had the symbology I wanted when I brought it into a web map - however I then went to check the pop-up, expecting to see the elevation values and what I got back was the RGB colour values for that pixel, which are fairly meaningless in this situation. Interestingly the rest end point for the image service now has the following details - 3 band integer image. So my question is whether there is an easy way to publish this image service so that it has the symbology that I want to use by default but has the underlying pixel value for elevation shown in the pop-up? Can I do something clever with function templates? Thanks in advance for any help. Gareth ... View more

Is there anywhere that documents which browsers are supported for each of the configurable apps in AGOL and/or Portal? Specifically I'm trying to work out if the AGOL Map Styler app supports IE11. I'm guessing not, but am also wondering if it did at some point because I've just been looking at a Styler app that I published last year which doesn't seem to work in IE11. I can only assume that it did at the time I published it because I tend to use that browser to test things and don't think I would have used that app template if it didn't work with IE. I guess it's possible that the version of the JS API that it uses has incremented over that time and no longer supports IE? I've looked in both the AGOL help page and the AGOL content item for the app but don't see any mention of browser support.  The closest I can find is the recent blog post about the minimalist beta template which doesn't support IE. Apologies if I'm missing something obvious here but just trying to make sure that I'm not going crazy! ... View more
