As we discussed in last week’s blog, many of you are using data that has already been set with the correct color, and therefore do not want any contrast stretching to be added.
Last week we discussed how to set the None stretch for any raster dataset added to ArcMap. This week we will show you how to set a property on a raster, so that is displays without a constrast stretch when it is added into ArcMap.
Setting a raster with no stretching as the default
The Source Type parameter on the Properties General tab allows you to set what type of data you may be dealing with. If you set this property to Processed then your raster will not use a contrast stretch by default.
To access this window, right-click on your raster dataset or mosaic dataset within the Catalog Window (or ArcCatalog), and click Properties. Then go to the general tab. Click the Switch to button, and choose “Processed”. Now when you add this raster to ArcGIS, it will use the None stretch by default.
Note: this cannot be performed for raster datasets that are stored as a geodatabase currently.
On a mosaic dataset
In ArcGIS 10.0 we added an option in the Default tab of the Mosaic Dataset Properties called “Is Processed Data”. At ArcGIS 10.1, we removed this from the Defaults tab and added the “Source Type” parameter in the General tab – to be consistent with a raster dataset.
Apparently this only works if your desktop client is at 10.1 and if your raster is a mosaic? I could not find a way to change a SDE raster that is not a mosaic. The “Switch to” does not appear. I attempted the switch on both 10 and 10.1. The “Switch To” only appears on the mosaic.
This only works if your Desktop client is 10.1. The top screenshot and set of information was for a raster dataset. Please make sure you are trying to perform this from the Catalog Window in ArcMap, or from ArcCatalog.
In 10.0, there was a different method that was in fact only for mosaic datasets.
My desktop is at 10.1. Does the SDE also have to be at 10.1? Our SDE is currently still 10.0. The process works for the mosaic but the raster does not have the dropdown. I tried both ArcCatalog and the Catalog window in Arcmap and there is no “Switch to”
It appears that it is a limitation within a geodatabase raster datasets at the moment. Sorry for the confusion. I will be sure to add that note to the blog.
Well, this obviously is not possible for raster dataset stored in sde geodatabse. Any idea if / when it will be possible?
I saw you can do this with set raster properties for a single image. I have hundreds to do stored in several folders. Any suggestions for doing this in batch?
You can run the Set Raster Properties tool in batch mode, or run a Python script.
