A mosaic dataset has a pixel depth property. This can be found in the layer properties of your mosaic dataset. Each item in your mosaic dataset also has its own pixel depth – and they can be different than the pixel depth of the mosaic dataset.

ArcGIS 10.0 Service Pack 4 (SP4) for English, is now available to our users for download via the ArcGIS Resource Center. This Service Pack contains performance improvements and maintenance fixes. Here are links to the downloads:
Release Note: ArcGIS 10.0 Service Pack 4 for the other five languages (French, German, Japanese, Simplified Chinese and Spanish) will be released in the next two weeks. A follow up blog entry will be posted to announce the availability once they are ready.
Calculating statistics are not always required after you apply a function. However, there are times when it may be helpful or even required.
When are statistics required?
Color correction requires up-to-date statistics. Therefore if any functions have been applied to your mosaic dataset, since statistics were last calculated, you will need to calculate them again.
When are statistics a good idea?
Often times when you apply a function, it can change the (virtual) pixel values. If you want to keep your mosaic dataset using the most accurate statistics and rendering, then you will need to calculate statistics again.
For instance, when you use the Stretch function to map your 8-bit data to a 16-bit pixel depth, your images will probably show up black, unless you calculate statistics.

Esri is committed to developing a community of partners that are actively implementing and extending ArcGIS for Local Government. To do so, Esri created an ArcGIS for Local Government Partner Specialty, within the Esri Partner Network, to make collaboration with partners repeatable and successful. The specialty is designed for partners focused on the local government marketplace that want to work more closely with Esri on the development and deployment of ArcGIS for Local Government.
Partners in the ArcGIS for Local Government Partner Specialty provide one or both of the following:
- Complementary applications that are based on the ArcGIS for Local Government solution
- ArcGIS for Local Government implementation services
Recently, several Esri partners have applied to be part of the Partner Specialty, and we are pleased to announce that we now have a growing network of partners that can assist Esri users to install, configure, and extend ArcGIS for Local Government. In the coming days, you’ll see these approved partners highlighted on the new ArcGIS for Local Government resource center.
In ArcGIS 10.0, we introduced a new raster geoprocessing tool Build Pyramids and Statistics. You can use this tool to build pyramids and calculate statistics for all the raster datasets in a workspace, and even in a raster catalog or a mosaic dataset.
This tool provides a convenient solution to build multiple raster datasets in single step. However it works on all raster datasets in the workspace. Although the tool does not contain a filter option to allow you select a smaller collection of raster among all, we can design a simple model to do this.
Is your mosaic being mosaicked in the proper order when you are using the Image Analysis window?
The Image Analysis mosaicking order is determined by the mosaic operator that you choose, and the order of the rasters in your Table of Contents. The order that you selecthighlight the rasters in the Layer List is not taken into consideration.
If you have made any changes to the default raster type, you will probably want to save your changes. This way you can re-use your custom raster type if you want to load additional raster data with the same properties and functions.
To save your custom raster type, click on the General tab. At the bottom of this tab, you will see a Save As button. Click the Save As button, and save it in the location where you keep all your custom raster types.
