I was under the impression that the Tabulate Area tool was for use with raster data but I now see it can do both.  I took a closer a look and when working with vector data, both the Tabulate Area and Summarise Within tools rasterize the data and a cell size needs to be set for Tabulate Areas.  I checked these three tools against my own data and the difference was minor, around 0.007%. Tabulate Areas was less similar than the other two but I suspect if I had to decrease cell size, it would match up. I then checked these three tools on the dataset you provided on Mangroves in central Mozambique and again the results were consistent.  For example: Tabulate Intersection: 85 376 ha of mangroves Tabulate Areas (50 ha cell size given fragmented extent of mangroves): 85 333 ha (I converted to ha) Summarise Within: 85 376 ha Therefore results from Tabulate Intersection and Summarise Within are identical and Tabulate Areas only 0.05% off.  Perhaps try again in a new view?  ...

Are you referring to the Tabulate Intersection GP tool  when you mentioned "Tabulate area"? I use the Tabulate Intersection—Help | ArcGIS Desktop  for these kinds of analyses and it lets you specify the output units. Unfortunately this tool does require a ArcGIS Desktop Advanced licence. ... View more

Thank you Tina. I think I now understand what has happened.  If you read this thread (Will the next release of ArcGIS Explorer for Android be able to show Beta release of ArcGIS Pro 2.1 ), it ends with a statement from Mark Bockenhauer where he indicated that the inclusion of rasters in MMPKs would not affect licencing levels (and MMPKs are viewable with a Lite licence). This is why I did not think our problem was related to licencing levels, which is contrary to what you have written and clarified for us.  This is unfortunate and my work with rasters in MMPKs will now have to be with Tiles.  Best wishes Mervyn ...

Hi Tina Thank you for clarifying the error message. Can I therefore assume that only publicly shared MMPKs with rasters, that are created using the Publisher extension, are able to be viewed in AppStudio (and @Explorer for ArcGIS too I imagine)?  There is certainly a need for securing the data in MMPKs, they cant all be made public.  Would it be possible to display secured MMPKs (with rasters) within apps with the next release of AppStudio? Or if there is any blog that discusses this, please let me know?  Regards Mervyn ... View more

Hi Tina I have a similar problem to that of Daniel. I had participated in the AppStudio 3 beta program and then installed your latest version of AppStudio (see below screen shot) I then downloaded the MapViewer template from AppStudio and tried to view non-public offline MMPKs that include rasters. The MMPKs with rasters would show in the thumbnails of the galley section, and I could download them onto device, but as soon as I try and open them I get a message "Attempt to use functionality that is not supported fo ...." See below. I was able to view your example MMPK (tiff1 = 1dd590f38fc14840b7917febe7344791) in a MapViewer once, but as soon as I added secured MMPKs, and activated "Supported secured maps" under settings, I was unable to view even your public MMPK (I would receive the above error). I tried to undo my settings and remove the secured MMPKs from the gallery, but still I could not view your MMPK.  Is the failure to view secured MMPKs with rasters by design, a bug, human error, or wrong version of runtime?  You have referred to " ..enhancements added to ArcGIS Runtime 100.2 and 100.2.1 ". If I open the MapViewerApp.qml, then I see I am importing Runtime  100.2 not 100.2.1 (see below). Should I not need to upgrade to 100.2.1 or is this implicit in AppStudio 3?  /* Copyright 2017 Esri etc import QtQuick 2.7 import QtQuick.Controls 2.1 import QtQuick.Controls.Material 2.1 import ArcGIS.AppFramework 1.0 import ArcGIS.AppFramework.Promises 1.0 import ArcGIS.AppFramework.Authentication 1.0 import Esri.ArcGISRuntime 100.2 import "controls" as Controls import "views" as Views ...

I also get the Invalid Taken. Code 498  error message if not the above error. This app is then usually uploaded to my account but it is faulty and does not display in the AppStudio Player. It shows under AppStudio for ArcGIS , but if I try and edit the app from here, it gives me the following warning "Oops! We cannot edit this app due to some errors occurred in the downloading process." I then manually have to delete it and try again. Yet to succeed.  I am using AppStudio 3.0.9. My app is small but includes a 150mb MMPK.  ... View more

I am having the same issue, unfortunately for me I have a bad internet connection both at work and home. I thought there was perhaps a size limit, hence the error, and was going to post a size question to this forum, but seems it may be timeout limitation.  ... View more

Ben, an alternative workflow to provide the same desired output would be a spatial join. Right click on your empty hexbins feature class, go Joins and Relates/Spatial Join. Then your Join Features would be your data points. Join operation is one to one. The new output feature class will contain a field called called Join_Count with a count of the data points per polygon.  ... View more

1. You could use Esri's Tile Package Creator (https://marketplace.arcgis.com/listing.html?id=9c9ddae83e5549bb88a2c22e87a18ba1) to create a tile package from the World Imagery service. 2. Then load this tile package into a new basemap map (Insert/New Map/New Basemap).   3. From here follow steps as provided in one of Xander's links Prepare your data for offline use | ArcGIS for Developers .  Note that you will only be able to view this new MMPK (that can now include raster images) in Pro and the latest release of ArcGIS Runtime SDK version 100.2. ...

Are you using Vector Tile basemaps? I encountered similar issue as current version of Collector still requires the older raster basemaps for offline (downloading) use.  ... View more
