Under the Image Properties dialogue, there is a drop down option where one can Adjust Image Altitudes. One can currently then Adjust using: (1) Elevation service or (2) Digital Elevation Model. But as many drone users make use of DJI drones, and the image altitudes are based off the altitude of take off site and flight altitude, hence it would be great if you could add a third option, the ability to adjust using a fixed altitude so that one does not need to create fixed altitude elevation rasters and import them as a digital elevation models. Do see David Schwab's post for more information (Drone2Map: How to adjust image altitude in EXIF metadata from DJI Drones ). This workflow works wonderfully but can be easily simplified with some code. In addition, it would also be really great if Drone2Map could lookup the Relative Altitude from image's EXIF properties to display under the Image Information dialogue box. Thank you.

Hi Thomas Thanks for the feedback. So this is then not happening on your side then I gather. I dont think this BUG applies as I am not using any custom templates, just creating a new project from Pro's default project templates. The map.gdb geodatabases are also empty where those in the bug report contain data. Just did a bit more testing. If you create a new project from a blank project template, then you only get one new geodatabase with same name as project. If you create a new project with a map then you get a geodatabase with project name and a map.gdb If you create a new project with a Global_Scene, then you get a geodatabase with same name as project and a Global_Scene.gdb If you create a new project with a Local-Scene, then you get a geodatabse with same name as project and a Local_Scene.gdb. I just dont see any data in these second gdbs so was wondering what their purpose would be. Thanks

For some time now I have been using Pro and have often wondered why two geodatabases are created for every Pro project. If I create a new project, Pro will create a geodabase with the name of my project and use this as the current and scratch workspace (I have accepted these defaults under Project > Options). It will also create a map.gdb file in same folder. If I use map notes, then these too are saved to the current project geodatabase. So what then is the role and purpose of the map.gdb that is created? I dont have a problem with it, just curious and want to understand why it is happening. There does not appear to be a help topic that addresses this, hence I am reaching out to this community. Any ideas?

Hmm, I would go for Tabulate Intersection as data does not need to be rasterised. It is also the only tool where you can set an output tolerance. I suspect the discrepancies you have seen may be related to the calculation of area on a planar surface versus a geodesic surface. However I suspect the tools would all be using a planar surface. Something to look into using the Calculate Geometry tool to compare with various outputs. I also noticed that I meant to write that the output cell size for the Tabulate Areas tool was set to 50 m not 50 ha.

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.

You can also add single coordinates in the Locate tool, using a comma to separate coordinates.

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

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.

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.

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.

You can create a continuous surface by interpolating on the Z-values using an interpolator like Natural Neighbor or IDW.
