Spatial Manager Enhancements

Several enhancements have been made to Spatial Manager in this release. For more information on Spatial Manager, see the Utilities section of the Spectrum Spatial Guide

  • There are now two ways to create a view table: Simple and Advanced. The simple view allows columns to be chosen and given friendly names in a visual query builder. Users can start with the simple view and toggle to the advanced view for entering full SQL syntax, if needed.
  • Named layers can be created or modified including assigning a table and applying style and zoom overrides.
  • Named maps can be created by browsing and adding named layers. The layers can also be re-ordered.
  • Spatial Aggregation is now supported on any JDBC-based XY tables. For more details on enabling the aggregation, see Support for Spatial Aggregation in the Resources and Data section of Spectrum Spatial Guide.

Feature Service Enhancement

A new REST operation to describe multiple named tables has been added to the Feature Service. This will significantly improve the client application performance where the client needs to describe multiple named tables. For more information, see the Services section of the Spectrum Spatial Guide.

Security Enhancements

The way permissions are defined for accessing the named resources and data has been fully revised. The changes include:
  • A new set of Access Control Service operations allows secure access to data. This service includes operations to grant, revoke, and view permissions.
  • Permissions can now be granted to specific repository folders to allow users or roles (other than admin), to manage their content (add, remove, and modify named resources).
  • Upon upgrade, the permissions will be migrated to the new model.
For more information, see the Services section of the Spectrum Spatial Guide.

Large Data Visualization

Spatial data aggregation is now available for generic JDBC X(longitude)/Y(latitude) data sources. For example, you can use Apache Impala for spatial data aggregation on a Hadoop cluster.

Performance and Usability

  • The rendering quality of the symbols on maps has been improved by enabling anti-aliasing, which ensures the borders of symbols appear smooth.
  • The search nearest operation of the REST Feature Service now supports the ability to return the nearest points between each nearest feature and the search geometry. This is similar to the search nearest operation of the SOAP Feature Service.

  • The REST Service performance is improved after changing the mechanism of serialization and deserialization of objects. The performance is more evident as the size of the response payload increases.

GDA 2020 Support

The support for GDA2020 Geocentric Datum for Australia has been added. The installation also includes the NTV2 .gsb files that further adjust any datum conversions between GDA2020 and either GDA 94 or AGD84 systems. By default these more detailed conversions are turned off. For more details, see Administration section of the Spectrum Spatial Guide.
