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).
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.
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 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.
Improved map display using HTML5 and CSS3
When supported by the browser, the API now uses CSS3 transforms to provide a smoother zooming and panning experience.
Support for the latest version of maps from ArcGIS Online
ArcGIS Online web maps with layers created from remotely hosted comma-separated values (CSV) files are supported. This includes fusion tables and CSV files hosted on the open web.
Enhancements to the Basemap Gallery widget
Support for new features in ArcGIS Server 10.1 beta 2
- Enhanced query capabilities that support order by and group by queries
- New GenerateRenderer task to automate the process of generating a renderer from data in a map service. The task can be used to generate class breaks, color ramps, and unique value renderers.
- New printing capabilities via a print task and print widget.
Additional API Enhancements and Bug Fixes
The Image Service Explorer is a sample web application that allows you to explore image services in web environment. This Silverlight sample has been very popular, and many new features have been added, and therefore we has decided to upload the latest sample for the Image Service Explorer 1.1. See the details in the link or within the Readme.txt file for more information.
The Image Service Explorer sample has been created and updated by Wenxue Ju.
The ArcGIS API for Flex enables you to build dynamic rich Internet applications (RIAs) for ArcGIS Server. The new 2.5 release includes support for WMTS layers, enhanced support for KML, and an improved editing user experience. It also supports cloud-based services hosted on ArcGIS Online (available for those who are beta testing the 10.1 subscription program for ArcGIS Online). Finally, the 2.5 release incorporates bug fixes and enhanced support for ArcGIS.com web maps.
The updated API is available for download from the ArcGIS API for Flex Resource Center.
Coinciding with the release of the API, the ArcGIS Viewer for Flex 2.5 is offered under the Apache 2.0 License, includes a new chart widget, and has its source code available on GitHub. This significant release includes a new experience for configuring the Viewer using an application builder, enabling new users to easily configure and deploy a new application without programming or editing an XML configuration file.
The updated Viewer is available for download from the ArcGIS Viewer for Flex Resource Center.
Using the new ArcGIS Viewer for Flex 2.5, you can use its application builder to interactively select web maps from ArcGIS Online as the data source for a new web application.
To add and configure widgets for the Viewer, just point and click.
The application builder contains an interactive WYSIWYG preview that you can use to see your map.
We hope you enjoy working with the latest release.

This is the developer event for ArcGIS. Plan now to attend and get the inside developer details on ArcGIS 10.1
VMware has published a technical paper describing the best practices for running ArcGIS Server deployed on VMware Infrastructure.

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.
