With the release of Spatial Modeler SDK 2020 we have added many new operators, LiDAR feature extraction, adaptive histogram equalization, texture analysis, Machine and Deep Learning, GeoMedia Features, Watershed delineation and pyramid image generation. For a complete list of new features see "New Technology" in the ERDAS IMAGINE® 2020 Release Guide.
There are also new APIs, including methods to allow Data Types to be sortable. For more information about new APIs as well as examples and guidance, see the Spatial Modeler Guide 2020 (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 2020 or GeoMedia 2020 software products or other Hexagon Geospatial software products which use the SMSDK 2020 Run Time environment, you will need to rebuild them with the SMSDK 2020. Also, if you are delivering your plug-in DLLs to one of the standard search locations, note that the version number subdirectory is "16.6", not "2020".
