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.

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.

Image Services as based on Mosaic datasets that can reference and mosaic together a large number of images. The server can not just pick up new files in a folder as it would not know the rules for how to process etc. There are tools that you can create to automate the creation of a mosaic dataset that could identify the new image, appropriately add it, set the required properties and republish/update the service. This can be set up to assure there is no downtime.

ArcGIS Image Server enables two types of image management: User Managed and Curated. The User Managed scenario is based on individual who have images/rasters uploading them to the server where if required the images are mosaiced and then streamed as tiled or dynamic imagery. This is good if many users in an organization want to contribute and share images they have. The Curated scenario is where the imagery is stored on a network (or cloud) storage and then the curator creates a mosaic dataset of the images. A mosaic dataset is a data model optimized for managing imagery. It is stored in a database, references the images and defines processing that may need to be applied to the imagery when it is accessed. The mosaic dataset can then be persisted as a tile cache or tiled imagery and served as (pre) tiled imagery or the mosaic dataset can be served as a dynamic image service in which case the server performs the required image processing and mosaicking of the imagery on-the-fly as it is accessed. The dynamic capabilities are very extensive and enables many derived imagery products to be accessed without the need to pre-process or store the different products. Many of these capabilities are also available in ArcGIS Image for ArcGIS Online.

ZIP is a container with lossless compression. The compression is generic an not optimized to imagery data. There are some versions of ZIP that can get better compression, but these are not standard so it may break your future readability question. Most imagery will not compress much if using most lossless compression. If the data is already compressed then and additional compression (eg ZIP) will add very little. The exception is some 16bit data or categorical data that has many repeating values. If you are just looking for generic compression to back up the data then this is available as part of the backup process should provide. If space is your concern then suggest optimizing the data using a more suitable compression. You can also exclude the overviews (which will save about 30%).

There is very little point compressing imagery using ZIP. I recommend against using ZIP to compress a directory of images. If you are looking for lossless compression of imagery then simplest is to use Deflate or LZW. There are some better lossless compression methods, but the differences will be limited. If you have collection of imagery that are not compressed and you want to compress them then its better run them through Optimize Raster to compress. Some datasets such as elevation compress better using compression such as LERC. For more details on how to convert and optimize imagery check out OptimizeRasters. Using Mosaic Dataset is the best way to manage the data as this references the source data (full resolution and any pyramids) and enables the definition of additional attributes, functions to process the data on the fly and enables quick access to all the data either directly in ArcGIS Pro or serving as image services through ArcGIS Image Server. When directly using the mosaic dataset in ArcGIS Pro it acts as a layer defining functions applied to the appropriate imagery. Yes you are accessing the full resolution source data when zooming in. The compression for transmission that you set is the compression used to transmit the data. It is the client application that can set it and the compression quality at any time. There is no reason to only allow ‘None’. As you mention setting this to say JPEG can speed up transmission of the data. There are Export and download options. Export will typically resample the data and apply any defined functions on the data. The application defines the resampling compression etc. Download downloads the original pixels were possible. I say were possible as if you use say a MrSID then the data is compressed and the data must first be decompressed before writing it to a new file so the data structure will change but not the pixel values (unless you define another lossy compression). You can directly use Mosaic datasets as input to your analysis tools. This enables large collections of imagery and rasters to be seen as a single dataset, with control of many properties. If you want to ensure that the pixels are exactly the same as those stored on disk then you should use the environment variables to set the appropriate pixel size, projection and extent to ensure the requested pixels align with the source. Do check out the ArcGIS Imagery Workflows page, it provides lots of best practices
