Hi Nyamjargal Sharav, It appears to me that you're missing overviews (or, they were not built correctly). In ArcGIS Pro or ArcMap, please add the mosaic dataset, select the area where you don't see images (overviews), then add selected rasters and overviews (in the Content pane > . Mosaic dataset> Selection > Add To Map). Now investigate the overview(s) (and, also the source image(s)). See if the overviews are built correctly. If not, investigate the source image (zoom in/out) and see the image is displayed at all zoom levels. If the overviews were not created correctly, these two might possible reasons: 1.    Bad internal pyramids (possible solution: fix pyramids and rebuild overviews) 2.    During the building process something went wrong e.g. output location was not available (possible solution: rebuild overviews) Also, a quick note about the geonet, please note geonet platform is for peer to peer help.It's not meant to get answers from Esri Support.

It's an old thread but I thought if you stumble upon it, you might find the following information useful: Pixel Editor contains a set of tools used to interactively manipulate pixel values for raster and imagery data. It allows you to edit an individual pixel or a group of pixels at one time. The Pixel Editor tools enable you to perform many editing tasks on your raster datasets: Edit elevation data to fill voids, remove spikes, or remove holes. Reclassify pixels, regions, or objects. Use preset filters to smooth areas. Obscure or redact confidential pixels. Remove above ground features to create a bare earth elevation surface. Replace a cloudy region with another region of pixels. Note: Pixel Editor is only available at  ArcGIS Pro 2.4 onwards (not in ArcMap). Also it requires the Image Analyst extension. ... View more

Hi Julio, World files (tfw) don’t carry all Spatial Reference information, please see: http://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/world-files-for-raster-datasets.htm . Not sure, if AutoCAd civil 3D can read the Spatial Reference information stored in the headers and/or aux or aux.xml files. Spatial Reference information is more important if you AutoCAd civil 3D map/layout is one Spatial Reference (e.g.  GCS North American 1983) and your Georeferenced Image is a different Spatial Reference (e.g. NAD 1927 UTM Zone 1N). Now, you will have to apply an appropriate datum transformation, if it’s available in AutoCAD, please see: http://desktop.arcgis.com/en/arcmap/10.3/guide-books/map-projections/choosing-an-appropriate-transformation.htm. If you don’t apply a right transformation, you may see some shift. So, you might want to check a couple of things: Your image’s Spatial Referenc Your AutoCad Maps/layout’s Spatial Referenc Apply a right transformation if necessary If using a World File, make sure it was using for the same Spatial Reference that you have in AutoCAD. Hope this helps. Regards, Pavan ... View more

Hi gia nguyen‌ To filter *.nc files only please try, the following: ncFiles = [] workspace = r"D:\test" #datatype limits the results returned. See supported datatypes: #Walk—Help | ArcGIS for Desktop. walk = arcpy.da.Walk(workspace) for dirpath, dirnames, filenames in walk:     for filename in filenames: #NC is not a supported datatype so filtering like this: "if filename[-3:]=='.nc'"         if filename[-3:]=='.nc':             ncFiles.append(os.path.join(dirpath, filename)) ...

Alex Sukupcak‌ See if the following works for you: import arcpy import os rasters = [] workspace = r"D:\test\Stowe.gdb" walk = arcpy.da.Walk(workspace, datatype="RasterDataset") for dirpath, dirnames, filenames in walk:     for filename in filenames:         print(filename)         rasters.append(os.path.join(dirpath, filename))     ...

Alternatively you can use the Clip Raster—Data Management toolbox | ArcGIS Desktop tool. But it all depends on your need. The Clip Raster tool is bit different from the the Extract by Mask tool. The Clip Raster tool cuts out a portion of a raster dataset (extent changes) while Extract by Mask tool does not change the extent of the raster but converts values outside of the clip feature/raster to NoData. here is one example: import arcpy import os workspace = r"D:\test\Stowe.gdb" arcpy.env.workspace = "D:\test\Stowe.gdb" fc = r'D:\test\Stowe.gdb\clip_feature' desc = arcpy.Describe(fc) xmin = desc.extent.XMin xmax = desc.extent.XMax ymin = desc.extent.YMin ymax = desc.extent.YMax rectangle = str(xmin) +' '+ str(ymin) +' '+ str(xmax) +' '+ str(ymax) rasters = [] walk = arcpy.da.Walk(workspace, datatype="RasterDataset") # for dirpath, dirnames, filenames in walk:     for filename in filenames:         print(filename)         rasters.append(os.path.join(dirpath, filename)) for raster in rasters:       arcpy.Clip_management(raster, rectangle, raster + "_clip") ...
