Error: Error 000950: Output raster exceeds the size limitation defined on the image server. Failed to execute (MakeImageServerLayer)

Error Message

When using the Make Image Server Layer tool in ArcMap 10.0 SP4, if the number of rows and columns for an image server layer exceeds the default values, the tool returns the following error message:

"Error 000950: Output raster exceeds the size limitation (rows: < value > and columns: < value >) defined on the image server. Please input a smaller extent. Failed to execute (MakeImageServerLayer)."

Cause

The Make Image Server Layer tool cannot produce an image server layer that is larger than the size specified in the image service properties. It can only access the data that falls within the extent defined in the image service properties.

Solution or Workaround

There are two solutions to this issue.

• Limit the amount of data that can be used by specifying a smaller extent within the tool.

• Increase the number of rows and columns in the mosaic dataset properties and the image service properties to allow a larger output.

The instructions provided describe how to change the mosaic dataset and the image service properties.

1. Mosaic dataset properties

A. Stop the published image service.
B. Right-click the mosaic dataset and select Properties.
C. Click the Default tab > Image Properties > Maximum Size of Requests > Increase the number of rows and columns.
D. Apply the settings.

2. Image service properties
A. Verify that the image service is stopped.
B. Right-click the published service and select Service Properties.
C. Click the Parameter tab > Image > Increase the values of the Maximum Size per Request parameter.
D. Apply the settings and re-start the image service.


Note:
Using the entire extent of a large image service can cause performance issues at the server end. This is because at any given time, thousands of users might be accessing the raw data for analysis or downloading raw data. Therefore, an increase in the number or rows and columns increases the time it takes to process the mosaicked image, and affects the performance of the server.
