With the release of Spatial Modeler SDK 2018 we have added many new operators (including Machine Learning Classification and Feature Extraction operators), the ability to set acceptable values and other contraints on Port Inputs, and the ability to easily use a Spatial Model as an operator in another model. For a complete list of new features see "New Technology" in the ERDAS IMAGINE® 2018 Release Guide.
There are also new APIs, including methods to facilitate a pattern of operator polymorphism. For more information about new APIs as well as examples and guidance, see the Spatial Modeler Guide 2018 (or download PDF below).
If you have used a previous version of the SMSDK, please note that for your plug-ins or applications to run with Hexagon Geospatial’s ERDAS IMAGINE 2018 or GeoMedia 2018 software products or other Hexagon Geospatial software products which use the SMSDK 2018 Run Time environment, you will need to rebuild them with the SMSDK 2018. Also, if you are delivering your plug-in DLLs to one of the standard search locations, note that the version number subdirectory is "16.5", not "2018".
