Feature Layer

A feature layer is layer that displays features contained in a table. FeatureLayers can come from native or native extended (NativeX) TAB data, remote RDB (Oracle, PostGIS, and MS SQL Server), seamless, raster and grid data and in-memory tables.

To modify the style of a FeatureLayer, add a FeatureStyleModifier. A FeatureStyleModifier is a construct that modifies the appearance of a feature in a table using specified criteria or algorithms.

A FeatureLayer is represented in Spectrum™ Technology Platform in four ways:
  • Embedded inline in a named map
  • As a named layer
  • In a SOAP request as an overlay
  • In a REST request as an overlay with an in-memory table.
