When you add an image to a Map in ArcGIS Pro, the properties/settings you set are saved as part of the Layer in the ArcGIS Pro project file. If you turn then on/off the settings will be kept. If you want to save the save the settings (including function chains) for a single layer then SaveAs Layer and you can add to other projects. For larger numbers of image I would suggest using Mosaic Datasets which enable the extensive settings to be saved for each raster.

Do look to use Mosaic datasets. They provide a lot of tools to work with overlapping imagery and defined rules for what image is displayed on top. You can also view the footprints similar to feature classes to identify, query metadata and add to new layers. If the input is just a bunch of layers that also consider Catalog Layers. They also create simple catalog of layers (including rasters) that you can see either as the layer or a set of footprints that can be selected etc.

For this type of imagery I would recommend using CRF or TileCache. CRF internally enables masking of JPEG so you get JPEG compression with suitable masking all projections are supported. CRF is very good especially for disparate data sets (eg along power lines) that could have a lot of no data areas. Use CopyRaster to create. The other alternative is to use Tile Cache, under the hood this users JPEG for tiles that have no nodata and PNG for others. In ArcGIS Pro you can use the Mange Tile Cache tools or the Generate and Publish tile cache workflow. Naturally I would also suggest you look into Drone2Map (or SiteScan) for processing the Drone imagery.

Please do the following 1- Create mosaic dataset 2- Add fields to indicate the variable 3- Build multi-dimensional info 4 - Run Copy raster process as multi-dimensional info enabled You say you see nothing on the screen when adding to the mosaic dataset. The help topic on this should provide the info you need. If you are seeing black it is likely that you need to apply DRA stretch or similar on the layer.

I tool a look. This is a strange file. It appears to be drone imagery that was originally 8bit and has been exported as a 12bit JPEG compressed image with 256 being defined as NoData and set using JPEG12bit compression . It is not clear to me if this the original image rotated or export from an orthorectification process. Such processing creates artifacts at the edges. (In the following I set NoData to organize to highlight the issue) JPEG has an issue in that traditionally it does not have NoData. The software that produced the image (could have been ArcMap) set NoData as 256. Please check this and set to 255 instead which would keep it in the 8bit range and compress much better. You will still see the JPEG artifacts. There are different ways to handle the masking of 8bit JPEG but it depends on how the image was exported. The 12bit version of JPEG is not natively supported in ArcGIS Pro hence it is converting to 16bit and using Deflate (lossless) compression hence the increase in size. There is a relatively complex work around using GLAD that can be done, but I recommend checking first on the source of how the images were created.

Strange. Could be related to the skipping a level (eg skip level1) or a different compression. Can you send a sample file that you have from ArcMap and will take a look. Yes, the pyramids created in ArcMap should work fine in ArcGIS Pro.

Thanks for the remarks and suggestions. The current navigation widget enables one to see the distribution of other image that are close to the selected location, but agreed that this is 2D and does not enable selection in 3D. If you are in a 3D scene and select a location higher or lower then navigation widget should re-arrange the images closest to that location, but it is not an optimum experience.. Also do look to turn on the Gallery that will show thumbnails of the images. This requires overviews of the image to be available, but on seeing the content can help make appropriate selection. In Oriented Imagery Classic there is an option to add additional filter based on an attribute. This for example could be the average height above ground and different levels can then be selected. There are plans to add an additional buttons that can subset the 'column' of images into virtual levels so that one can then move up and down the column easier. Similar to levels in a building. This may help. If you have a recommendation on how you would feel it optimum please do post the suggestion/recommendation.

Brian is correct. The source data has 0 defined as NoData for all 4bands. Following an extract from GdalInfo The image has 0 values in the red band so they are (correctly) being interpreted to represent no data. A no data pixel affects all bands. Instead of doing Compute, you can also set the value to 256 (out of range). You may find in other samples at the edge of the image that there are areas that appear black, but you want transparent. Check the data values here you may find that the Band4 is using 255 (or 1) for no data in these areas in which case set NoData in band 4 to 255 (or 1)

Not sure why the reclass would be changing the georeferencing. It should not. Consider adding images to the mosaic dataset computing the footprint and then doing the reclass. The reclass can anyway be a function applied on the image and not require a temporary image.

‎11-21-2023

Not clear to me why this would be happening or why you need to recompute footprint. If the radiometry had changed the footprint should not. I'm wondering if there is something wrong in the control points being used or the transformation method define. Are you defining the georeferencing as using control point files which then does not create new images. The aspects of footprints and seamlines with scanned maps can be quite interesting in that there are many ways to clip them. Often the extent of the image is not what one wants as the footprint. There are also cases where it is advantageous to use seamlines so that the maps with and without legends can be accessed. There are also considerations on how to do georeferencing so that no unnecessary sampling is applied to the images. Do take a look at Imagery Workflow - Managing Scanned Maps

Yes, It appears from afar to be correct

Suggest you load add some of the source data, zoom in and compare the values. Are their differences? Also look to use the hillshade function to better symbolize. Also you will find more tools, better visualization etc in ArcGIS Pro.

The PostAddRaster.png is likely correct. The data is floating point elevation data and what you are seeing is a single mosaic of the whole areas rendered with the lower parts in the North dark and then I assume some higher plain are to the south as white. If you for example apply a hill shade on the image I expect you will see the detail. Alternatively turn on DRA and zoom into different areas The ActualTilesEntireArea.png is showing each tiles with a default render being applied to each tile individually.

Thanks for the explanation of the value of Image Services with Experience Builder. I agree. I cant give too much detail here, but there is a WABIS replacement in the works. Hope to provide more details. "EXBIS" We need to think more about that as a name. Proposals welcome.

Why are you attempting to create a vector tile package vs TileCache? You need no delete the .OVR Process should be : Create Mosaic Dataset Add Images from folders From table or select tool, select image from each input folder and use Merge Mosaic Dataset items. This will in your case reduce the number of footprints to 3 In properties of Mosaic dataset, Set mosaic method to By Attribute, Object ID. (To keep order fixed) and Clip to footprints on Zoom to see the imagery. Review the footprints and use editing tools to clip along requested extent. Generate Tile Cache, but 'Maximum Source Cell Size' to a value about 1.5x the cell size of the largest set of images. This will ensure that overviews are not required but crated form higher resolution cache. Please see 'Serving Cached Imagery' If you want more advanced merging take a look at the Seamline processes by which you can also defined blends etc.
