Mask function is the good option. Those areas are still part of the raster even if they have no value.  I would be good if there was a compact function for rasters would compress out those null value areas.  Another option if you have a good photo editor is to cut the image and delete out those null areas.  However, this will probably result in a feathered edge. I have a mosaic dataset that stores two regional single-band (grayscale) images.  In one of the images, there are areas where the pixel value is zero.  I don't want to display these pixels, so I have tried both 1) setting the NoData value of the Mosaic Dataset to 0 (and displaying NoData as transparent), and 2) selecting "Display background value [0] as [transparent]".  Both methods properly set the pixels to transparent, but unfortunately, these transparent areas overlap my second image, obscuring it.  I have enabled time on the mosaic dataset, set the default mosaic operator to "FIRST" and configured it to sort in descending order of the time field (i.e., more recent images have higher priority).  So, whenever the first regional image (with the transparent areas) is the newest image, it is mosaicked over the second image, which obscures the second image's pixels, even when the higher-priority image's pixels are NoData/transparent. Does anyone have a suggestion as to how to resolve this?  I realize I could clip the first image, but would prefer to avoid that.  Is my only other option to configure my mosaic operator/sort order to always prefer the second image, or is there a way to avoid mosaicking transparent pixels?

There is a possible chance your tiff was made from a compressed image format and the those pixels are the result of being uncompressed. You may be able to fix it in something like photo shop. Or possibly bring it into Picassa (copy  of image please) and try the I feel Lucky button.  Either way you are probably going to lose image quality without manually going through the broken pixels and manually adjusting them.  Once images are broken it is really hard to fix them.  Not impossible just not rewarding. I am trying to build a mosaic dataset from tiled source rasters (.tiffs).  The problem is that there are two places with a 1 pixel gap across the entire set of rasters running horizontally.  It looks to be related to precision issues when they were generated. Is there a way to sample the nearby pixels from the adjacent rasters and use the resampled value to fill in the gap? Thanks, Nathan ... View more

Oh, and those speckles are simply imperfections in the raster.  There is enough color there so the show up as a color. The image was probably scanned at the time it was made digital. If you have a really good photo processor you may be able to open it there and cut the edges off. It is just a rough edge. Hello All, I have historic aerial photos in TIFF format: [ATTACH=CONFIG]24202[/ATTACH] These display just fine (in State Plane) The problem arises when I re-project them to UTM (NAD83) -> JP2 format (same with TIFF format too) There is a dark area (some what resembling the extent). [ATTACH=CONFIG]24203[/ATTACH] When I set the display nodata value of 0 to NoColor, I get a tolerable image but still has some speckles in the collar area and holes inside (obviously 0 is a value). [ATTACH=CONFIG]24204[/ATTACH] During the re-projection process: I tried various methods - resampling, setting NoData, compression , etc. Evrytime it is the same result (dark around). [ATTACH=CONFIG]24205[/ATTACH] Am I missing something? Is there a work-around? Thanks ... View more

Double click on the raster in table of contents. Click on the symbology tab. There is a check box for Display Background Value:  Check that  to the right are places to enter values and next to that is a drop down box to select color. Choose that and select no color. What you are seeing is the full extent of the raster and by default it will give it a black color.

Are Joe and Vince actually serious about saying feature datasets are a bad idea. Feature datasets do have a specific purpose.  They allow you to categorize your data for a GIS and organize it in a database.  It would be foolish for a user to have their landbase in one database, their electric or sewer or forest or mine sites etc.. dataset in another database etc.. Please let give me more information about the unintended consequences of using feature datasets for something they are not designed for and what you think they are designed for.  My apologies I am not trying to be p*ssy I am just flummoxed. Gotta go along with Vince on this.  I'd much rather manage multiple databases then get bogged down in the unintended consequenses of using feature datasets for something they are not designed for. ...

For call out those are the two options. You can change the leader tolerance and the margin around it text. IF you just want to use a different symbol you can use a symbol but not with the call out balloon I want to use a callout text on my map but the callout background has only 2 options:  rectangular or rounded rectangular.  I want some other shapes such as oval.  How can I create a new callout with oval shape? Any inputs are welcome! Thanks! Winnie ... View more

yes a good method is to create subfolders in your file geodatabase. In the FGD they are called Feature Dataset Right click on your FGD and select New > Feature Dataset Now the Feature Dataset will prompt you for a projection to use. So you can create individual Feature Datasets and load Feature classes into it. Example. I word in Electric Utilities.  I have Feature Dataset for Electric (all features I want in a geometric network) Landbase Electric2 (all electric related features I don't want in the geometric network) MapData (datadriven pages polygons, and other features used for map production) Anyway that should give you the idea. However, when you do this you will have to repath all your MXD's to the new feature locations. Hello, I've been processing some data in a file geodatabase. I'm finding the geodatabase to be getting very full of data and increasingly hard to navigate. I was wondering if there was a way of creating sub folders or sub directories in the geodatabase? Or would I just be better creating lots of seperate geodatabases depending on the area I'm studying? ... View more

If your only doing it the one time don't bother with model builder simply so it with select by attributes. However, when you perform it in model builder it does not export a new feature class.  simply to the select by attributes.  it will make your selection then perform the calculate function on the appropriate attributes. Hi, I have a feature class where I wish to select various values from a field. Once those values are selected I wish to populate another field with a corresponding certain value using calculate field. How can I simply select attributes in a feature class without exporting to another feature class? Thanks Mark ... View more

I have had the same issues in the past. I have my workstation set to perform these operations every Tuesday after I leave.  Then our IT dept runs a full Virus Scan sometime in the middle of the night. Huh, it seems to be working now. It had frozen up after I did all the steps you suggested before, so I task manager-killed it. Now that I think about it I don't know if I restarted the application after your suggestions. So now that it's opened up again it seems to be working fine. I'm not sure which step was the one that got it to work sadly 😞 But thank you for the help! You were very quick with your responses. ...

what type and what memory does your GPU have? Does the air photos load and operate just fine when they are the only things loaded from a new session? My drive has a lot of space on it still, almost a brand new computer. I cleaned the disk, and defraged it. Browser history and cache was cleared the other day for a different issue. My task manager showed arcmap being the top memory eater so I don't think that's the problem. My MXD file is about 600 KB. No luck. I can load raster data no problem and work over my server on other applications without an issue. It doesn't feel like a networking or computer issue but again I am no IT specialist. ... View more

As far as the copy paste goes.  It would work best if you only have the two datasets open.  zoom in close and pause the refresh. It should work with that number of street lights. But you computer may not be able to to handle the amount of data all at one time.  I recently did it with 34,000 poles. Hello, Can anyone possibly suggest the best method for loading data into a versioned feature class that is part of a geometric network?  I have a versioned feature class of streetlights in a geodatabase that is part of a geometric network.  I also have another non-versioned feature class of additional streetlights I want to add to the versioned data.   The schemas in both do match. There are many streetlights 15,000+ in the non-versioned data.. I have begun using copy & paste in an edit session with the versioned data as the target layer.  This approach does work if I copy small numbers of rows each time (say 50-100).. however it is very time consuming. I have tried object loader, but it fails each time.. I often run out of memory.. Any ideas? JS ... View more

Multiple methods.  Easiest Method:  From an edit session in ArcGIS have both the old and the new on screen. IF Both features have the SAME attributes simply copy and paste the new into the old. Easy:  From an ArcGIS session. Use the Append command to append data from new to old.  Works similar to Load Data in ArcCatalog but it allows you to do to a versioned  database. Not as easy but still easy:  Compress your database a couple times.  Unregister as versioned.  Use the Data Loader to load data. Compress again.  Register as versioned.  If it does not work you will need to delete the geometric network after the unregister as versioned.

First generate the X,Y of the annotation and create a point.  the point if created from the same table should contain the annotation text. There is a command called Bulk Snap Command which you can download that will use classic snapping rules to snap selected features to what you have designated.  Then do a spatial join of the point to the street layer and the various polygon layers.  You end resulting point feature will have the name attribute from each of the different layers joined together. Apologies for the confusion. I need to base the index on both the roads featureclass and the annotation. Each listing must be based on the road centre lines, suburbs and page numbers, whereas the grid reference must be based on the annotation. And if there is no annotation, there should be no listing. Could you elaborate a bit on your idea of snapping the annotation centre point to the road centre line and then giving it the suburb (and page) attributes? This looks like a manual process which seems like a labour intensive task as this map book contains 100+ pages so going through and snapping every annotation centrepoint to the relevant road on each page and then duplicating it for each suburb and page combination, would take forever. The index process has to be as automated as possible as it would be repeated for other map books. ... View more
