Hi there. I have a different issue -- I have a referenced mosaic dataset with a number of functions applied.  Since it covers much of South America, I need to clip out a small portion as a flat raster file to send to someone.  When I view the mosaic and classify it in Arcmap 10.2, it looks great, just like I need it.  Now, I export my area using Data > Export Data > to a .tif file.  Usually, this works great for clipping rasters to an AOI.  However, when I do it now, it creates my new raster, but WITHOUT THE FUNCTIONS APPLIED.  Why is this happening?  Is there a better method? Thank you! True! If the function-chain applied into regular MD 10.2.1 or earlier (you can treat it as imagery processing processes) and then a NEW referenced MD is derived from this MD, the referenced MD will show changes, including spectral (as your finding). Personally, it could be bugs or limitations on referenced MD. Not sure if ESRI is aware of this issue before ... ++++++++ However, if the referenced MD is created /selected from a regular MD, which contain many �??pre-processed�?? images by ERDAS/ ENVI/ PCI (not through function-chain in MD), this NEW referenced MD will retain same quality as the original MD (see the attachment). In fact, �??referenced�?? MD has many limitations, compared to regular MD. Please refer to the Help Documentation on Referenced MD for the details. ... View more

I would like to keep the files as TIFFs if possible but I gave your suggestion a try. Exporting as an IMG produces the same incomplete result. On removing gaps and slivers among scenes, please refer to the GP tool at http://resources.arcgis.com/en/help/main/10.2/index.html#//001700000087000000 +++++++++++ Here, I gave some BASICS/ thoughts on why 'suspected' colormaps cause issue, which should be removed before adding into MD... Look-up Tables vs. Colormaps [INDENT]LUTs (Look-Up Tables) are fundamental to many aspects of image processing. An LUT is simply a table of cross-references linking index numbers to output values, which is widely used in remote sensing and photogrammetry. In cartography or GIS, however, the most common use is to determine the colors and intensity values with which a particular image will be displayed, and in this context the LUT is often called simply a �??colormap�??. One disadvantage of using a colormap is that it introduces additional complexity into an image format. It is usually necessary for each image to carry around its own colormap, and this LUT must be continually consulted whenever the image is displayed or processed. Another problem is that in order to convert from a full color image to (say) an 8-bit color image using a color image, it is usually necessary to throw away many of the original colors, a process known as color quantization. This process is lossy, and hence the image quality is degraded during the quantization process. Additionally, when performing further image processing on such images, it is frequently necessary to generate a new colormap for the new images, which involves further color quantization, and hence further image degradation. As well as their use in colormaps, LUTs are often used to remap the pixel values within an image. This is the basis of many common image processing point operations such as thresholding, gamma correction and contrast stretching, which is very common in some photo processing packages. The process is often referred to as anamorphosis.[/INDENT] ... View more

Great, the workaround looks ok, ... On 'export�?? from MD, it should work fine with 10.2/10.2.1, if the exported image format in (IMG) is used (as long as MD is good). ... View more

hey im using arcgis online and arcmap 10.2.1 i have a polygone feature service online and i made a local copy (that gave my the layer, the attachment table and the sync file beween the both) so i can make DDP based maps/ each feature has a .jpg attachment  that i'd like to put on my DPP/ how do i do it??? TNKs Ofer Yoav, If understanding correctly, please read the link at http://blogs.esri.com/esri/arcgis/2013/07/22/map-tour-story-map-template-updates/ for reference. With the above template of 'Map Tour', good idea to directly use Yahoo! Flicker photos in ArcGIS Online. Of course, you can also import all photos into ArcGIS Online... ++++++++ If the security is one of major concerns in your organization, the Portal for ArcGIS can be used as enterprise �??cloud�??, which should be combined with enterprise RDBMS /SDE (managing photos and  feature class with geotagged photos) and ArcGIS Server  (feature class service)�?� ...

I am working with historic aerial photography over Panama to observe the change in forest cover over time. All of the frames have been added to a mosaic dataset with shrunken footprints and seamlines. All images have had the grayscale function applied as well at 8 bit depth. The issue I'm running into is with the color balancing tool. Each frame has artifacts that I've minimized with another software (MaxIM DL) with gradient removal and flat fielding. My goal is to color balance the images and perform a histogram matching on the mosaic so that pixel values are consistent throughout. The error I receive follows: "Color correction does not currently support data with colormaps. Color correction will not be applied." When I try the delete colormap tool it claims that the input raster does not have a colormap. Has anyone run into a similar situation when mosaicing aerial photography? Any advice would be much appreciated. Casey, If your images from MaxIM DL are suspected to have �??inherent-colormap�??, you can verify and work around.  Please use other packages like ERDAS or ArcGIS importing into IMG/ TIFF first, and then load into MD for CB testing�?� On CB (color balancing) on �??grayscale�?? images, pls try to use 10.2.1. It should work fine�?� Plese share your finding... +++++ If yes with �??inherent-colormap�?? (i.e., the issue still exists, after importing into IMG /TIFF), it is better to check if the saving-image process used �??Auto Stretch�?? in MaxIM DL, during processing image (stretching, adjusting, etc.). Mostly, you can try to adjust the stretch �??manually�??, before saving... ... View more

I recently attend the 2014 ESRI Developer Summit Conference.  In the sessions that I attended there was no discussion of any web hosted client functionality other than that which is provided by ArcGIS Online (AGOL).  As you probably know, AGOL is a very limited form of ArcGIS Server in the cloud, e.g. no support for image services, custom code, geoprocessing, etc. ESRI did discuss the upcoming release of ArcGIS Professional which is  essentially a next generation ArcMap. Thx, Richard We have learnt some from several ESRI presentations on the coming release of ArcGIS Professional, which looks promising to GIS professionals, in particular, as an integrated desktop GIS platform. However, on very limited information about the coming �??desktop�?? ArcGIS Professional, we haven�??t seen any in-depth topics /presentations on the following aspects: [INDENT]1. How to closely collaborate each other over �??cloud�?? (via Portal for ArcGIS or ArcGIS Online), especially, on geocoding, processing, feature extraction from raster,  and 2D/3D analysis, in addition to �??static/dynamic�?? mapping /3D visualization; 2. How to integrate CityEngine to support real �??3D Printing�??; 3. How to innovate the existing ArcGIS Server/ ArcSDE to support the above new capabilities/ functions over ArcGIS Pro, including if to support managing 3D raster (stereo-pair/model, panoramas, oblique photos, LiDAR, etc.)[/INDENT] ...

Our data was acquired under a special "government" license type. We have not received the data directly form vendor, but from a resseler. We'll notify them about the issue.

Thx, The Q is: Are your data not from the vendor directly? In other word, if you are going to modify the metadata one by one, it would be an operational issue. Isn�??t it? How is that happening?

Vitor, It looks that your RE products are not supported in ArcGIS (MD)�?� not sure if those are standard RE products (1B or 3A). In fact, we also had same issue with RapidEye products, which is exactly similar to Astruim standard products (SPOT 5, Pleiades PAN). We already reported this Astruim (SPOT 5, Pleiades, and SPOT 6) issue as remedy to ESRI and urgently wait for their reply. For details, please refer to the discussion thread at http://forums.arcgis.com/threads/81139-to-expedite-the-development-supporting-RPCs-of-Pleiades-sensor-1A-and-1B?p=373251&viewfull=1#post373251 So, advisable to report it as the remedy and seek ESRI for investigation�?� +++++ To me, the issues with Pleiades and SPOT 6 are bugs in ArcGIS. However, with RapidEye products (1B, 3A) and SPOT 5 products (1A, 2A), not sure what leads to this happening during loading into MD? (I.e., our operational data from vendors are Not 'standard bundle' or bugs in MD?)... ... View more

10.2 will support both Pleiades 1A and 1B as well as SPOT6 products. As with 10.1 RPCs are directly supported and georeferencing can be refined using the georeferencing tools in which control points can be used. Peter, The incident was reported to ESRI as a remedy AR316, 4-5 months ago (meanwhile, sample data were partially uploaded to ESRI site). It is referred to: MD in ArcGIS 10.2 does not support Astrium sensors bundle data (DIMAP v1 & v2) properly, including SPOT 5, Pleiades, and SPOT 6; and it can be cataloged as three cases during loading the bundle: [INDENT]  For SPOT 6, it is not functional, when enabling �??Background GP processing�??; but it can work smoothly, when disabling  �??Background GP processing�??; For Pleiades, it couldn�??t recognize PAN; but it works with MS; For SPOT 5, it completely does not recognize 2A TIF data, even though the Metadata /SCENE01 icon looks fine.  (it looks that IMAGERY.TIF.zip in the bundle 2A lead to this issue.)  [/INDENT] The incident is reproduced in 10.2.1 as well in both workstations and laptops. Not sure if it is a known issue �?� and wondering if the team can help investigate it as high priority, in particular, associate with the bundle data of 'SPOT 6' and 'Pleiades-1A'. Regards, ...

...  able to successfully (I think) publish a mosaic dataset as an Image Service in ArcGIS Server. I am able to view the service in ArcMap but when I try to view it using the Javascript viewer nothing shows up ... Vince, It looks that it is related to �??improper�?? use of cache mechanism. When you publish MD (Mosaic Dataset) as an image service, you will see a 'Caching' tab. If selecting the mode �??using tiles from a cache (folder)�?? in the server, it will cause this issue. [INDENT]In the documentation, it says that this mode will enable an image service to be directly cached by the server. In fact, in the enterprise environment, it mostly wouldn�??t work as expected. [/INDENT] For solutions to this issue, two options: [INDENT]1. publish via �??dynamically from the data�??; 2. If �??using tiles from a cache�?? , please refer to the thread at http://forums.arcgis.com/threads/102621-cache-raster-tiles-in-server-vs.-desktop. Worth to mention, it seems that this mode only works fine with 10.2 or 10.2.1 (recommended). [/INDENT] ... View more

we are importing a collada file in ArcScene through 3D analyst (conversion<from file<import 3D files) but we are getting 2 buildings as a single multipatch file(open attribute table):mad:. how we separate or edit multipatch? Yogita, Pls separate and edit in the 'original' 3D modeling package where the COLLADA model is exported from  (saying, SketchUp Pro, CityEngine, or Maya), rather than ArcScene. When the 3D model is exported from 3D modeling package as Collada, mostly, its individual 3D entities associated with the intelligences are lost (i.e.,  3D model only as a block). ... View more

... Note that the MD was developed to manage nadir imagery, but the catalog capabilities of the MD provide powerful capabilities for managing and accessing oblique imagery.  Oblique images will normally be accessed one image at a time, to view an area of interest. ... Cody Benkelman Thx, Cody, More enquiries on �??oblique�?? photos for you to help. From ESRI raster /3D perspective, with �??oblique photos�?? (and other 3D raster), can you share any successful practice/ projects, which are managed at server and then deployed with ESRI 3D GIS platform? In other word, pls make more recommendation on server-side management of �??oblique�?? photos data /models (and also 360 0 panoramas, �??cloud point�?? from stereo-pair or LIDAR, and DSM models from stereo-pair, If possible), so that those 3D raster can /will be easily integrated into ESRI 3D GIS platform (desktop 3D, web 3D), including ArcGlobe, ArcGIS Explorer (3D mode) & web (globe)? Regards, +++++++ One of the pre-conditions to manage 3D raster at server is: those 3D data/models should /can be, at least, directly visualized (in 3D mode) at clients. Certainly, it would be better to anayze, measure, even extract 3D GIS data/ models from those 3D raster. In the market, there are several solution products available, which can be used to manage 3D raster at server, but it looks that those solutions still are very far from seamless integration into ESRI 3D GIS platform (or via plug-in & API). ...

Yes. ... If an image service with a cache is added to Desktop then in the layer properties one can select if to access the cache of the dynamic image service. In web applications the app needs to define what mode to request the service in. Currently in a webmap you can not switch between the two modes. Thx, Peter, It works. The view mode in desktop 10.1/10.2 can effectively switch from the cache mode to regular image service, as expected... Great job, thx a lot, team! ... View more
