Job You should use a Mosaic Dataset to access and process multiple images - see What is a mosaic dataset?—Help | ArcGIS for Desktop    The Mosaic Dataset creates a VIRTUAL mosaic on-the-fly from many images, and allows you to do exactly what you're asking - apply band arithmetic to all images as if a mosaic, but the mosaic is dynamic (e.g. if you have an image w/ clouds in foreground, you can bring a background image to the foreground using the Mosaic Method).   also note the Image Analysis Window allows you to run NDVI but specify any bands, so if you need that exact math, just use NDVI. You should not need to copy pixels and output new rasters, just do everything on-the-fly in the Mosaic Dataset, then if you really need an output image you can use Export to save to disk. Cody B. ...

Job My apologies if the user doc for that renaming script were not clear.  Did you run it and not succeed?   Wait, I see that the string you copied above ("Change parent_folder_path to the input folder to be renamed") comes directly from the script; did you see the user doc in the download?  Text is copied below Cody B. If path renaming is required, users can run the script ‘RenameSentinel2Data.py’ (found in the Scripts folder) and pass in the name of the folder containing the GRANULE subfolder, e.g.: > python.exe RenameSentinel2Data.py d:\XXX_Long_Path_XXX\S2A_OPER_PRD_MSIL1C_PDMC_20150818T101216_R065_V20150806T102902_20150806T102902.SAFE If the user has multiple satellite scenes, the script ‘RenameSentinel2Data.py’ can take the root folder as input and will rename all subfolders named S2A*NAME.SAFE, e.g.: > python.exe RenameSentinel2Data.py d:\XXX_Long_Path_XXX ...

Kory raises a good point - the path names are inherently long, and if over 255 characters it causes problems.  In our workflow download (referenced at top Workflow to create Sentinel 2 Mosaic Datase) includes a python script to shorten path names to address this problem. ... View more

It sounds like either your SID files are corrupted, or else there is something wrong with your installation of ArcGIS.  I'm uploading a small MrSID file - try loading that into ArcMap and let us know if it works.  If you have a colleague running ArcGIS, try your SID files on his/her system. ...

Karolina What version of arcmap and server are you using?  Do you have the image extension, to allow you to publish a single image service from a mosaic dataset (with the mosaic dataset referencing two or more satellite images)?  That is the method I would recommend - the mosaic dataset provides a great deal of control over how images are displayed, and it can be scaled up to reference literally millions of images in a single image service. re: web app, are you using the default ArcGIS Online web map, or some other app?  Last, if you are allowed to share your image service endpoints with us, we can explore the configuration to give you better advice.

John - this is an excellent question and unfortunately one that can confuse a lot of people.  The answer is "it depends on where you access the LASD to load it into the tool". If you access the LASD from the TOC, that's actually a LAYER based on the LASD.  Any filters applied to the LASD will be shown in the layer, and if you drag that layer into a GP tool, then the filters will be applied. If you access the LASD from ArcCatalog, then filters applied in the map are NOT applied. Settings on the LASD itself (e.g. features used as hydrologic constraints) apply in all cases (e.g. both when viewed in the map as a layer, or when processing in a GP tool). Note the toolbar is simply a handy shortcut to the layer properties, so toolbar or TOC-->properties both apply to the layer, then will be honored (applied) only if you input the layer into the GP tool. ...

Greg Good question!  Yes you can do this. You want the SERVICE pixel value, not the ITEM pixel value.  The Service value includes any functions which are applied - so in your case the value returned is Height Above Ground.  In the screenshot below, you set the popup to "Display a list of field attributes and then select "Configure attributes" to get the UI shown, then turn on the Service pixel value.  (I left the ITEM pixel value on as well). notice that the default label is "Service Pixel Value" but in my second screenshot, you see that text can be selected and changed, so the popup will be labeled "HeightAboveGround" In the AGOL World Elevation service, we don't have height above ground, so below I show a similar example but reporting the slope in degrees as well as the ground elevation: ...

Elie Did you try what I described above?  Perhaps I was not clear that the "Raster Product" is something defined by ArcGIS to summarize the entire satellite scene.  If you will read our help to understand what the Raster Product is, and then open ArcCatalog and find the Raster Product icon (looks like a raster with satellite on top of it), you can expand the Raster Product (+ sign) to find "multispectral" inside, and drag that into the map. Either that, or as noted in my original post, learn how to create a mosaic dataset and add the Geoeye scene into it using the GeoEye raster type, then add the mosaic dataset into the map. Note if you are not finding these options please let us know what version of ArcGIS you are using.  I am assuming you have 10.3 or later?  If you are using a much older version my advice may not be appropriate ...

For a single scene, you can simply drag the Raster Product into the map (using ArcMap).  Find the Raster Product in ArcCatalog.  Help is here What is a raster product?—Help | ArcGIS for Desktop if you are working with multiple scenes, you'll want to create a Mosaic Dataset (What is a mosaic dataset?—Help | ArcGIS for Desktop ) and then when you add the images, be sure to use the GeoEye Raster Type (Satellite sensor raster types—Help | ArcGIS for Desktop) ...

Nearly any drone should work, but note Drone2Map is for still frame imagery, not video.  If you are acquiring video from a drone, our newest release of FMV (v1.3, available late Jan/early Feb) will be able to "multiplex" GPS data with a video file to geotag the video.  More information coming soon Get Started with ArcGIS Full Motion Video (FMV/Drones/UAS/UAV) re: Drone2Map, it's not the drone that we need to understand - the key is the camera (although the flight plan for acquiring imagery does impact the project as well).  We'll have a long list of compatible cameras that should make the camera portion of project setup transparent to the user, but if you are using a previously unknown camera, the key parameters needed are simple - focal length and sensor size (mm) or pixel size (microns).  GPS can be embedded in each image (EXIF tags) or an external file read in with the images.  If you have these inputs, Drone2Map should be able to process your still frame imagery. ...

If my previous guess was wrong, then it appears you must have selected "Draw this image service using tiles from cache" in the caching tab when you published it.  Can you confirm?  This generates raster tile cache, which is the same as the imagery seen in ArcGIS base maps (as well as Google, Bing, etc.) - this is the fastest mode for serving imagery, but it's fast because the imagery is pre-rendered and the server simply looks up the tiles and transmits them.  It is no longer a dynamic image service, so changing raster functions is no longer possible.  In either a map service or a cached image service, under the layer, there are 3 dots to pull down "more options", but none of the other modes that appear on a dynamic image service - e.g. see below - where you would have icons for "Show Legend", "Show Table", "Filter" and also the 3 dots for "more options" where you'll be able to select any server raster functions that are available. I should verify - is the shaded relief working properly, and your concern is that you'd like to be able to disable it, or select other functions?  If you need other functions, you'll need to republish as a dynamic image service (and you may want to find and delete the cache that had been generated).  If all you will ever want is the shaded relief, the cached service should work for you.

Greg You had me stumped for a while - I could not understand how you got that menu without the Display options - but I think I figured it out. I believe you saved an MXD and then pulled down File/Share As (see screenshot) - is that correct? That publishes a MAP service, not an Image service.  If you check your service endpoint, (see screenshot) you'll see "MapServer" not "ImageServer"  (see my 4th service, vs. the 2nd one). To publish an image service, you can select the Mosaic Dataset or image file in ArcCatalog and then right click  to "Share as Image Service".  (In the UI for publishing the Image Service, you'll see "Functions" where you can add more functions onto the service if you did not add them onto the Mosaic Dataset prior to publishing) Let me know if you need more detail Cody B. ...
