ArcGIS Image Server 11.1 includes updates, enhancements, new tools, and improved functionality.
If you're upgrading from 11.0 or an earlier release to ArcGIS Image Server 11.1, you must reauthorise your software. You can obtain a new license file from My Esri.
Imagery content management
- Supports exporting hosted imagery layers to tile packages.
- Vector field template—Now supports scientific raster types such as netCDF and GRIB in the Create imagery layer wizard.
Map Viewer Classic
See the following sections for updates on imagery display and raster analysis available for Map Viewer Classic.
Imagery layer
- Performance improvements for dynamic imagery layers.
- New multidimensional imagery layer user experience to investigate and explore the imagery layer.
Raster Analysis
The following tools and functions have been updated.
Raster analysis tools
The following tools are enhanced:
- Distance Accumulation and Distance Allocation—The algorithm for horizontal and vertical factors was rewritten to be non-distorted instead of 8-directional. Performance was enhanced and space optimizations were made when calculating straight-line distance.
- Find Argument Statistics—The Choose statistics type parameter has a new option, Argument of the value, which enables a Specify argument value parameter. Two additional parameters also become available, Comparison and Occurrence.
Raster functions
You can launch raster functions from the Item Details page on the Content tab by clicking the Open in Raster Function Editor button, or you can access the raster functions by clicking the Raster Analysis button.
The following new raster function has been added:
- Surface Parameters—Determines the parameters of a surface raster such as aspect, slope, and several types of curvatures using geodesic methods.
For existing functions, the following updates were made:
- Distance Accumulation and Distance Allocation—The algorithm for horizontal and vertical factors was rewritten to be non-distorted instead of 8-directional. Performance was enhanced and space optimizations were made when calculating straight-line distance.
ArcGIS REST API
The following updates have been made for ArcGIS REST API.
Raster function objects
The following new raster function object is added:
- SurfaceParamFunction—Determines parameters of a raster surface such as aspect, slope, and several types of curvatures using geodesic methods.
- MultidimensionalPrincipalComponents—Transforms the data into a reduced number of components that account for the variance of the data to identify spatial and temporal patterns.
Raster analysis tasks
The following raster analysis tasks have been enhanced:
- DistanceAccumulation and DistanceAllocation—The algorithm for horizontal and vertical factors was rewritten to be non-distorted instead of 8-directional. Performance was enhanced and space optimizations were made when calculating straight-line distance.
ArcGIS API for Python
See the Release notes 2.1.0 for arcgis.raster module and submodule updates.
