To assess the correlation between these 3 rasters, you can use the Band Collection Statistics tool. See Band Collection Statistics—Help | ArcGIS Desktop and How Band Collection Statistics works—Help | ArcGIS Desktop  ... View more

Is this not possibly using the Duplicate layer properties under the Structure tab when in Format Polygon Symbol? Like in this image? ... View more

Have you ensured that you have enabled the layer to be selected under the List by Selection options of the Contents pane? By default, running GP tools bypass this option for restricting which layers can be selected.    ... View more

Hi Nakul The problem was that I had not activated the external storage capability. Thank you so much for picking that up! Much appreciated.  Working perfectly now.  Paul, thank you for your help too. ... View more

Hi Paul The MMPK is bundled with the app. Some of the code used from offline MMPK sample:     property string dataPath:  AppFramework.userHomeFolder.filePath("ArcGIS/AppStudio/Data")     property string inputdata: "Blyfstaan.mmpk"     property string outputdata: dataPath + "/" + inputdata ...

I once posted a related question to the Pro 2.0 beta group when I could no longer find the background offset option in Pro 2.0 and Jeff Barrette kindly provided a detailed explanation which should be helpful to this thread.  "Functionality did change between 1.4 and 2.0. There are two ways to accomplish this. First (and recommended) is to use the Format ribbon. Select your legend, click the format tab and from the current selection control you can select your background and then set background fill color, outline color, width and gap x and gap y. gap x and y should provide you the same capability as your layer effect in the symbology pane. I hope this will provide the experience your are looking for. The second option is a little more difficult to explain because it really depends on the current state of the background symbol. By default, there is not a border or a background fill. So when you use the legend pane / background options, and select the layers tab, only stroke appears - by default. Stroke ALWAYS exposes an offset effect. Fill color doesn't. But if you don't have a fill color, then you need to add that via the format tab and the instructions above. Now if you revisit the layout / background symbology pane there will be a fill layer. But no offset effect. To see the offset effect, you need to manually add it. To do this you need to click on the "structure" sharkfin (tab) and add the offset. Now return to the layers sharkfin and voila it is there. I hope you find option #1 more useful. Option 2 provides a lot of functionality but it takes more effort." However I can never get Option 1 to work for me to set background offsets (all the rest works great) so I resort to Option 2 where the I have to manually go and add offsets as an option, then select it to set the necessary offset values. I wish offsets were added as a default value as it is with legend outlines (I did request that last year).  ... View more

I am not sure if this will solve your problem, but I had a similar problem. It is my understanding that with the current version of Collector, you are unable to take Esri's Vector Tile Basemaps offline (this will change soonish I gather). So currently you will need to author your web maps with the older Raster Tile Basemaps. However, if your organisational account manager has opted to enable "Use Esri vector basemaps in supported ArcGIS apps" in your organisational account settings, then you wont able to add the older raster-based basemaps to your maps as only the newer vector tile maps are provided by default in the basemap switcher for your AGOL account and maps. This means you cant take them offline when you open these maps in Collector. Your administrator should unselect the above option and then you need to open your maps, add in a new basemap, save, then you should be able to take the maps offline.  But all of this still requires that you follow Dan Moore's advice on configuring the maps in AGOL for offline use. ...

Hi Kylie Thank you, this is what I was hoping to get :-). I have downloaded file and will try the installation on the tablet tomorrow. Regards Mervyn ... View more

Hi Ken There is nothing recent to send as an example. Several years ago I was unable to run several intersect tasks involving land cover and vegetation types. The datasets were massive, and I thought it was just too big a task for AcrMap. But after running Dice, I was able to easily complete my analyses running the GP tools (I think I used* Erase *too). Since then I almost always run Dice on complex polygons before a large GP task and the tools always work. I have continued with this "best practice" even with ArcGIS Pro. Good to know that Dice should probably be reserved until after a tool fails, then only try and run *Dice *and see if that helps. Thanks Mervyn ... View more

For large geoprocessing tasks like this I usually: (1) use Dice split up polygons with more than 20k vertices; (2) run Repair Geometry to find and correct any geometry errors that may have crept in; and (3) I save output to a geodatabse. ... View more

Hi Brooke Thank you so much for sharing the example. Very much appreciated. I shall take a look and let you know if I have any questions. Regards Mervyn ... View more

Hi Michael (not sure why I called you Robert in my last post) There is not much that I can add other than suggesting the GCP approach may be your best approach. If accessing surveyed GCP is problematic, you could use Collector and Esri have a new template on AGOL that allows you to create a feature layer using one of their templates designed for capturing GCPs for D2M. Collector can also be set to average GPS collections under settings.  If you are keen, go to your Content/Create/Feature Layer/ then search for "drone". You can then create a feature layer that will assist in capturing of GCPs.  If you use the georeference option, depending on where you are located, you may have access to high resolution aerial imagery on AGOL that can be used you to correct both images as neither are correctly, or adequately, georeferenced using the raw image GPS coordinates.  ...

Not sure whether this is what you are looking for but to easily duplicate a layout, or map, open Catelog / Layouts. Then right-click on the layout of interest and select "Copy". Then right-click on Layout folder and select 'Paste'. This will create a copy of your layout that can then be renamed and modified.  ... View more
