Not exaclty sure what you mean about browsing for the item in my org. If I upload the PDF to AGOL and make it available to Field Maps there doesn't appear to be a way to have that PDF available as a basemap on the device unless I lock a Web map to it. I can do that however, and when I go offline, the PDF gets downloaded as the basemap. The issue though is that there's no way to change the basemap to a different PDF without running into the error. Just got the notice below BUG-000183698 has been closed: As Designed. This is as designed, it is a workaround related to the limitations of Adobe products. The Esri Projection Engine included in Adobe Acrobat is an older version that does not support Web Mercator (EPSG 3857). In order to provide any georeference information in exported PDFs using Web Mercator, we write an older EPSG code that is properly supported by the projection engine version included in Adobe products. If at some future juncture Adobe updates their copy of the projection engine, we could modify PDF export to write the newer Web Mercator Auxiliary Sphere.

I don't know but I just tried bypassing Pro entirely by exporting a GeoPDF using the print widget in an AGOL webmap. I was thinking I'd get a clean file that way. The output draws fine in Pro, CRS looks good. Does Field Maps like it? Nope. Its starting to seem to me that there's more here than just a BUG with Pro.

Hmmm... I found that I can update the CRS in a GeoPDF using GDAL in Pro from osgeo import gdal
gdal.Translate('GeoPDF_out.pdf', 'GeoPDF_in.pdf', format="PDF", outputSRS="EPSG:3857")
When I review the output GeoPDF file CRS properties in Pro all looks great and it draws in the correct location in a Map. However, when I bring it into Field Maps I get a slightly different error than before "Basemap Unavailable - The basemap doesn't have a valid spatial reference" This is odd since it is working correctly in Pro.

I opened a support ticket and they got back to me with this same information early this morning. I guess this got rolled out a bit prematurely. Bummer.

@JonathanLebowitz I've tried it by pre-specifying a GeoPDF as the offline basemap in the item details page and also without specifying an offline basemap at all (just using the Map default). Results were the same. Yes, the original basemap in the map was also EPSG:3857, its the World Imagery layer. My GeoPDF's are just exports of three different ESRI basemaps, Pencil, Antique, and Community. No other layers at all. Brought the GeoPDF back to Pro by a drag-and-drop, then checked it's properties through the TOC. I've been referring to Jeff Shaner's March 2, 2026 blog post about using GeoPDF's https://www.esri.com/arcgis-blog/products/field-maps/field-mobility/add-geospatial-pdfs-to-your-field-maps-workflows

I'm getting a "Basemap Unavailable - The spatial reference isn't compatible with this map" error when attempting to switch to a GeoPDF basemap in an offline Map. I created three GeoPDFs in Pro, all at the same time, and side-loaded them to the Basemap folder on my device. They all show up in the Basemap Gallery in Field Maps and work fine in dynamic maps. However, if I attempt to pick one while using an offline map I get that spatial reference error. I made sure that the Map SRS in Pro was set to WKID:3857 before exporting the GeoPDFs. However, one oddity is that when I brought them back in to Pro, their WKIDs are listed as the outdated Web Mercator tag of WKID:3785. Anyone else seeing these types of issues or got any ideas? iOS 26.3.1 Field Maps 26.1.1 ArcPro 3.5

Thanks James. I'll look into the add-ins. After thinking on my original question, a suggested improvement might be to provide 'options' in the app settings to control the post/store behavior if desired. E.g. 'check this box to store on device and post later' vs. 'check this box to prompt user for post/store choice' along with the ability to start an additional survey automatically after the store/post.

Is there any way to remove the "Survey Completed" splash screen in the mobile app? I understand that part of it's purpose is to provide a choice when the device is Online. However, when Offline, there is no purpose to it and you must just 'click-through'. This is pretty frustrating in that it requires two taps/clicks to complete a survey and then another one to start up a new survey, so I'm hoping someone can point me to method to avoid/disable it. Thanks!

We just ran into an issue trying to get ArcGIS LAS Datasets and Mosaic Datasets to correctly interpret the coordinate reference system in a LAS 1.2 file header. The LAS 1.2 spec uses the GeoTIFF GeoKey tags as opposed to the newer 1.4 spec which uses the WKT. Does anyone know which GeoTIFF GeoKeys translate to form the Geographic Coordinate System (GCS) portion of an ESRI defined coordinate system? We tried to define a GCS_North_American_1983 using: key 2050 - GeogGeodeticDatumGeoKey: Datum_North_American_Datum_1983 key 2056 - GeogEllipsoidGeoKey: Ellipse_GRS_1980 but for ArcGIS this resulted in: Datum: D_North_American_1983 Spheroid: GRS_1980 Semimajor Axis: 6378137.0 Semiminor Axis: 6378137.0 Inverse Flattening: 0 I'm wondering if perhaps instead we should be using: key 2048 - GeographicTypeGeoKey: GCS_NAD83 key 2056 - GeogEllipsoidGeoKey: Ellipse_GRS_1980 Does anyone know this spec and how to have it correctly interpreted?

Is there a way to specify the output SR when using the Print dijit or will we have to recode our app using the print task?

Hmmmm..... I can see how William Carr's implementation is one path to a possible solution. It needs some tweaking, like a loop to run through all the [items] returned to the getTextContext function so each one gets displayed in the infoWindow. Mainly I was trying to avoid a multiple "Task" methodology where there are queries for the first click and then another query for the relationship and then another click to display the popup. The out-of-the-box implementation of the popup at v 3.10 of the api handles the related query for single click solution, there just doesn't seem to be a way to call the returned records except using the mediaInfos structure which is irritating.

Did you ever find a solution for this? I just ran into the same problem. I can see that the related values are returned to the client by examining the response in Firebug but can't figure out how to get it to display in the Popup. My template is defined like this: var popupTemplate = new PopupTemplate({ title: "{PARK_NAME}", fieldInfos: [ { fieldName: "POLYID", visible: true }, { fieldName: "relationships/0/FEDNUM", visible: true, label: "FedNum" }] }); Below is the screenshot of the popup as well as the response shown in Firebug.

The radians thing didn't help me either so I used this to return a North Azimuth based reference. Hope it helps someone... Field (type double) = NorthAzimuth( !Shape! ) Codeblock: def NorthAzimuth(Pline):
degBearing = math.degrees(math.atan2((Pline.lastPoint.X - Pline.firstPoint.X),(Pline.lastPoint.Y - Pline.firstPoint.Y)))
if (degBearing < 0):
degBearing += 360.0
return degBearing
