If you want the original DEM values between 1000 and 1255, why do you want to add 1000?  I will share with you the workflow I would follow to achieve this (but without adding the 1000). I like using Raster Functions as I can test the settings and I don't have to save the final output to disk. From Imagery tab, open up Raster Functions and search for Calculator.  Add you DEM as the Raster Variable and assign a character to it (like x in my below image).  Under Expression, Type in Con and hit enter to enter your conditional statement. Then you can type Con((x>=1000)&(x<=1255) , x , 0 ). I was not sure whether your highest pint is 1255 or you only wanted to display that range. Then under the General tab, change the Output Pixel Type to values to 16 Bit Unsigned, then hit the Create new layer at bottom of pane. As Jayanta pointed out, your DEM is unlikely to be a 8 Bit Unsigned type as the values are greater than 255. I also noted from your image that it has 3 bands. Are you displaying the properties for the DEM you want to work with?  Similarly, the output of the Raster Function cant be a 8 But but rather a 16 Bit type to show values greater than 255.  If you want to add 1000 to teh DEM values then you modify the Con statement to something like: Con((x>=1000)&(x<=1255) , x+1000 , 0 )   ...

One option would be to create a new raster with the required/desired range of min and max values using the Create random raster GP tool.  But use the GP tool listed under Data Management toolset  and not  Spatial Analyst tool as the former lets you specify minimum and maximum values. Then symbolize it and save as lyrx file. Then from your thermal infrared raster images, import the symbology from your new lyrx file you just created.   It should give you your desired symbology.  ... View more

The .shp.xml file is found with all shapefiles that Ersi software works with.  See image. Unfortunately I do not know where the equivalent is stored in a geodatabase.  Hopefully someone from Esri can advise.  I was hoping one may be able remove the default symbology from Catalog but that does not appear to be the case.      ...

HI Joe Esri seem to have made some serious changes to its symbology in version 2.7. I have witnessed what you describe several times now and Pro seems to embed the last used symbology as the default symbology with each feature class or shapefile.  So when you add a layer to a new project, the last use symbology is automatically applied by default.  I noticed that the .shp.xml file now includes this default symbology, and if you delete it, then the shapefile will load without the last used symbology.  I usually find the new behaviour to be favovourible in most instances yet there has been the odd occasion where it was undesirable.  It would be nice if this was one of the Options that a user can choose to activate or not.

I don't think I made myself clear, sorry about that. You can still add your TPK files to your SD card (and I have a 1.3 GB tpk available to me as a basemap on my SD card), you just need to access the correct folder  with a  little more effort.  So browse to the following folder on your SD card, and then copy your basemap into this folder. "SD Card\Android\data\com.esri.fieldmaps\files\basemaps".  The unfortunate part of this workflow is that each app (i.e. ArcGIS Collector, ArcGIS Field Map, etc), will require their own basemaps and the apps can't share a common basemap.  ...

Dear Sveinung I can only reply to the question about basemaps as I have done in Field Maps. The latest releases of Android make it more difficult for Esri to utilise folders outside of those created when the app is installed so you now need to place your basemaps in "Galaxy A70\Card\Android\data\com.esri.fieldmaps\files\basemaps" (in may case but it should not be different to yours).

The easiest approach may be to first open up the CSV in Excel and then combine the two fields into one field using a formula such as "=TEXT(C2,"yyyy/m/dd ")&TEXT(D2,"hh:mm:ss")". But then once you add the CSV file to Pro, your new field will be recognised as a text field and not a date field, so then you need to run the Convert Time Field GP tool to convert it to a date field.  ...

Hmm, I am using Pro 2.7.1. I will test this behaviour on a different project.  Thanks for checking. ... View more

Just to add that I noticed last week that Layer Masking also resets (unfortunately) when changing the definition query of a layer that is being used as the mask.  ... View more

Hi there   I am not a specialist in this field but will attempt to answer some of it, but hopefully someone from Esri can jump in and correct me. So, firstly, I am surprised that the Topographic basemap that you downloaded gets blurred as it should be a Vector Tile package where the lines should still remain crisp at most scales.  Can you confirm that it is a vector tile package? Under your contents, right-click on the World Topographic Map that you downloaded and go to Properties, then Metadata and confirm that Vector Tile Package is listed under Tags?  Historically enabling Vector Tile Basemaps was done at the administrator level for your organisation, hence we need to check.   I suspect that to create a mmpk of the entire New Zealand you will probably have to go with a Vector Tile Package in your mmpk. The file sizes are just so much smaller than in standard Tile packages. I had a quick look at the NZ LIZ topographic map and it is a geotiff served off an Image Server. To download this at reasonable resolution for NZ will just be too much for any mmpk I suspect. You may need to break the country up into regions and then create an MMPK for each region.    But it is always best practice to focus on a smaller sample area to test the methodology (resolution and file sizes in this case) to assess whether your approach may be feasible.  So choose a smaller area and then play around with downloading the LNZ topographic map at a resolution that may be acceptable, then try and go larger to see if that can work. However you may find that one of the other Esri Vector Tile basemap options may work for you (take a look at the Navigation basemap, the OpenStreetMap may also be a good option) Good luck ...

It sounds like the resolution of your image is too coarse. I am not sure which layer disappears? NZ LINZ ... or World Topographic, but the cause is the same. When  you downloaded the World Topographic map, you had to select a maximum scale for the vector layers. If you select a more coarse scale (larger) value, then when you zoom in beyond that scale, then the map will disappear in Pro. Basically the data is too coarse to be visualised properly.  So when this happens, you need to try and download a finer scale version of the layer.  The good news is that if you put this MMPK onto a mobile device, and view it in either ArcGIS Field maps for ArcGIS Explorer, the layers should still be visible regardless of how far you zoom in, it may just not be very clear! ...
