ArcGIS Image Server 11.4 includes updates, enhancements, new tools, and improved functionality.
If you're upgrading from 11.3 or an earlier release to ArcGIS Image Server 11.4, you must reauthorise your software. You can obtain a new license file from My Esri.
Imagery content management
- Imagery type attributes have been added to the Content page of your organization to provide more information about the imagery layers in your organization.
Map Viewer
See the following sections for updates on imagery display and raster analysis available for Map Viewer.
Raster analysis
Raster analysis tools
The following raster analysis tools have been enhanced:
- Distance Accumulation, Distance Allocation—Have two new options for the Vertical factor parameter: Hiking time and Bidirectional hiking time. The performance of these tools is also improved if the Distance method parameter value is Geodesic, or if the Vertical factor or Horizontal factor parameters are set.
- Distance Accumulation, Distance Allocation, Optimal Path as Line, and Optimal Path as Raster—Distance analysis can properly handle the edge of the projection at a global extent, when using either a cylindrical projection or a geographic output coordinate system and the Geodesic method.
- Distance Accumulation, Distance Allocation, and Optimal Region Connections—Cost raster values that are negative or zero are invalid but are now treated as small positive values; previously they were treated as NoData.
- Zonal Statistics—Has four new options for the Statistics type parameter: Majority count, Majority percentage, Minority count, and Minority percentage.
- Zonal Statistics as Table—Has six new options for the Statistics type parameter: Majority count; Majority percentage; Majority value, count, and percentage; Minority count; Minority percentage; and Minority value, count, and percentage.
Raster functions
Raster functions are now available in Map Viewer.
Raster functions templates
The Raster Function Editor is accessible from Map Viewer from the Analysis pane, providing access to the Raster Function Editor to create or modify raster function templates. Previously, you could open a new raster function template from the bottom of the Raster Functions tab. Now you can access the Raster Function Editor directly from the Raster Function Templates tab to create, edit, and manage your raster function templates for analysis.
Raster analysis environments
Two new environment settings are now available for raster functions:
- Number of retries on failures—Specifies how many times the same worker process will be attempted when there is a failure during the processing of a particular job.
- Recycle interval of processing workers—Specifies how many image sections will be processed before restarting worker processes to prevent potential failures in long-running processes.
ArcGIS REST API
The following updates have been made for ArcGIS REST API.
Raster analysis tasks
The Geographic Transformation environment has been added to all raster analysis tasks that honor Output Spatial Reference.
The following raster analysis tasks have been enhanced:
- DistanceAccumulation, DistanceAllocation, OptimalPathAsLine, and OptimalPathAsRaster—Distance analysis can properly handle the edge of the projection at a global extent, when using either a cylindrical projection or a geographic output coordinate system and the geodesic method.
- DistanceAccumulation, DistanceAllocation, and OptimalRegionConnections—Cost raster values that are negative or zero are invalid but are now treated as small positive values; previously they were treated as NoData.
