Offline basemap with tiff aerial image and hosted vector layers

[logri-sl]

Hi all,

I’m setting up a survey based on high resolution aerial imagery in an area with slow and unstable internet. I need to take my basemap offline, and it must include a .tiff file containing the orthophotography, along with some hosted vector layers. Ideally, only the aerial imagery would be downloaded to users devices, while the vector layers would stay updated online. I’ve tried following all the tutorials I could find, both on this forum and in Esri's documentation, but I haven’t had any succes so far. My understanding is I need to start by creating a TPK from my aerial image and then include it with the hosted vector layers in an online shared MMPK (is that even correct?). But ArcGIS Pro won’t let me do that, and I’ve tried every methods I’m aware of.

Has anyone achieved this before and could offer some guidance?

Many thanks,
A

Can you share information about how the TIFF file and the vector layers are stored. Are they all locally stored, or hosted features / tile layers.

In our organisation I have had no problem publishing mobile map packages directly to my enterprise portal, then through Survey123 Connect desktop application, through linked content I can link the Mobile Map Package to the Survey123 map, meaning that when users download the Survey123 form they will also be downloading the mobile map package for use within Survey123 offline.

Hi Nigel, thanks. The vector layers are hosted online, as well as the tiff file (as a tile layer). The hosted vectors layers actually are the survey's records. I need the users to be able to see the features they submit.

Could you detail the steps you took to achieve what you mention?

From what I have tested I am not sure about having an downloaded basemap for offline use (imagery) with live vector layers within Survey123, but I have been able to publish both locally stored basemaps and vector layers within a single mobile map package, which is published to the Enterprise portal as a single piece of content (mobile map package) published from ArcGIS Pro.

This way you can have both your raster data and vector data within a single offline package, but separating both your offline raster imagery with online vector data I am unsure.

But how did you manage to do it in the first place? If you look at my first message, what you're describing is exactly what I'm struggling with.

I would actually use Field Maps for this.  It is way better at the mapping and offline stuff.
