ArcGIS Image Server 11.3 includes updates, enhancements, new tools, and improved functionality.
If you're upgrading from 11.2 or an earlier release to ArcGIS Image Server 11.3, you must reauthorize your software. You can obtain a new license file from My Esri.
Imagery content management
- Continued enhancement for cloud storage support for Deep Learning Studio.
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 are added to Map Viewer:
- Derive Stream as Line—Generates stream line features from an input surface raster with no prior sink or depression filling required. Specific locations for sinks or depressions can be provided. An optional accumulation threshold can be specified.
- Derive Stream as Raster—Generates a stream raster from an input surface raster with no prior sink or depression filling required. Specific locations for sinks or depressions can be provided. An optional accumulation threshold can be specified.
- Detect Change Using Deep Learning—Uses a deep learning model to detect change between two raster layers.
- Locate Regions—Identifies the best regions in the input raster that meet specified size requirements and spatial constraints.
- Multidimensional Principal Components—Transforms the multidimensional imagery layers into a reduced number of components that account for the variance of the data so that spatial and temporal patterns can be readily identified.
- Nibble—Replaces the cells of a raster corresponding to a mask with the values of the nearest neighbors.
- Stream Link—Assigns unique values to sections of a raster linear network between intersections.
The following raster analysis tools have been enhanced:
- Geodesic Viewshed—Two new viewshed settings parameters, Vertical error and Refractivity coefficient, and four new observer parameters, Horizontal start angle, Horizontal end angle, Vertical upper angle, and Vertical lower angle, are added.
- Surface Parameters—A new parameter, Input analysis mask raster or features, which limits analysis to specific locations of interest within the input surface raster, has been added.
Imagery layer
Map Viewer Classic
See the following sections for updates on imagery display and raster analysis available for Map Viewer Classic.
Raster analysis
Raster functions
The following raster function has been enhanced:
- Zonal Statistics—Four new options for the Statistics Type parameter have been added: Majority count, Majority percentage, Minority count, and Minority percentage.
ArcGIS REST API
The following updates have been made for ArcGIS REST API.
Raster analysis tasks
The following raster analysis tasks are new:
- GeodesicViewshed—Determines the raster surface locations visible to a set of observer features using geodesic methods.
- TabulateArea—Calculates cross-tabulated areas between two datasets and outputs a table.
- ZonalGeometryAsTable—Calculates the geometry measures (area, perimeter, thickness, and the characteristics of an ellipse) for each zone in a dataset and reports the results as a table.
- ZonalStatistics—Summarizes the values of a raster within the zones of another dataset.
The following raster analysis tasks have been enhanced:
- DistanceAccumulation—Two new Vertical Factor options are added, HIKING_TIME and BIDIR_HIKING_TIME. The performance has been improved when using the Geodesic method or Vertical or Horizontal parameters.
- DistanceAllocation—Two new Vertical Factor options are added, HIKING_TIME and BIDIR_HIKING_TIME. The performance has been improved when using the Geodesic method or Vertical or Horizontal parameters.
- SummarizeRasterWithin—Four new statisticType options are added, MAJORITY_COUNT, MAJORITY_PERCENT, MINORITY_COUNT, and MINORITY_PERCENT.
- ZonalStatisticsAsTable—Six new statisticType options are added, MAJORITY_COUNT, MAJORITY_PERCENT, MINORITY_COUNT, MINORITY_PERCENT, MAJORITY_VALUE_COUNT_PERCENT, and MINORITY_VALUE_COUNT_PERCENT.
