How to download rasters from an image service
Now that you have shared your downloadable image service, how does a client download rasters? Below are the steps to download rasters:
- Add an image service into ArcMap.
- Make selection either by creating a query (Select By Attributes), or by using the selection tool (Select By Rectangle).

Share your source rasters within an image service – Part 2
Can I allow the users to download more than 20 rasters?
The “Maximum number of items downloadable per request” parameter limits the number of rasters that a user can download for each request. This means that a user can download 20 rasters (20 is the default value) at a time, and then they can make another request to download another 20. Obviously this can become tedious if you have thousands of images. If you do not mind users from downloading more than 20 rasters per request, then you can set the number to a higher value.
How do I set the maximum number per download to a higher number?
The number of rasters that can be downloaded per request on the server cannot exceed the maximum number that has been set on the source mosaic dataset (which is 20 by default). Therefore you will first have to edit the properties on the mosaic dataset itself. Then you can set the server limit.
- Right-click on the mosaic dataset, and click Properties
- Click on the Defaults tab
- Scroll to the bottom, and look for the Maximum Number of Items Downloadable per Request
- Edit the value in the “Maximum number of items downloadable per request” to the desired maximum value
- Click OK
Now the maximum number has been raised on the mosaic dataset itself. You can now edit the maximum value within the image service, as described in part 1 of this blog.
Share your source raster within an image service – Part 1
Image services are a great way to allow others to use your service layers within their GIS projects. Did you know you can actually allow users to download your source files? By default, this option already enabled when you publish a mosaic dataset. Continue reading
National Geographic World Basemap
National Geographic and Esri have collaborated to produce this cartographically distinctive basemap that reflects National Geographic’s cartographic design, typographic style, and map policies.
This basemap provides a visually appealing background for web mapping applications for mobile users, consumers, and educational purposes, and is also well suited as a general reference map for many GIS projects.
This National Geographic World Map has been added to the collection of existing ArcGIS Online basemaps that users can access freely for internal and external use.
Get more details about this map and start using it today.

Functionality Matrix for ArcGIS 10 and Server
By Aileen Buckley, Mapping Center Lead
ArcGIS is available in three license levels: Basic, Standard, or Advanced (formerly ArcView, ArcEditor, or ArcInfo, respectively). These license levels share the same core applications, user interface, and development environment. Each license level provides additional GIS functionality as you move from Basic to Standard to Advanced. Sometimes you want to know what functions are available at what levels. To find out, use the ArcGIS for Desktop 10 Functionality Matrix: http://www.esri.com/library/brochures/pdfs/arcgis10-functionality-matrix.pdf.
This matrix also includes functions for the optional ArcGIS for Desktop extensions which offer specialized tools and additional capabilities to enhance your system.
If you’re using Server, there is also a functionality matrix for ArcGIS Server: http://www.esri.com/library/brochures/pdfs/arcgis-server-functionality-matrix.pdf.
