Update 1 for ERDAS IMAGINE 2018 is primarily aimed at improving the NNDiffuse pan sharpening technique which was initially introduced with ERDAS IMAGINE 2018. The update provides OpenCL-based GPU acceleration for the technique, which in some instances can result in a two orders of magnitude increase in performance. The algorithm has also been fine-tuned to provide even better color fidelity compared to the original Multispectral data.
In addition, there are new Operators, such as the Linear Regression operator, as well as numerous software quality improvements.
Hexagon Geospatial Licensing 2018 v18.104.22.168 (the version provided with the ERDAS IMAGINE 2018 installer) or higher should already be installed. It is strongly recommended that all ERDAS IMAGINE customers upgrade to Hexagon Geospatial Licensing 2018 v22.214.171.124 (or higher)
Hexagon Geospatial Licensing 2018 v126.96.36.199 is also integrated into the ERDAS IMAGINE 2018 Update 1 installer. If ERDAS IMAGINE and Hexagon Geospatial Licensing 2018 are both installed on the same computer, installing Update 1 will also automatically update the Licensing to v188.8.131.52. If in doubt, refer to Windows’ Add or Remove Programs utility to determine the currently installed version.
No (additional) license is required if you already have ERDAS IMAGINE 2018 licensed.
