document describes the enhancements for ERDAS IMAGINE 2018 Update 1 (v16.5.1), including IMAGINE Photogrammetry (formerly LPS Core) and ERDAS ER Mapper. Although the information in this document is current as of the product release, see the Hexagon Geospatial Support website for the most current version. This release includes both enhancements and fixes. For information on fixes that were made to ERDAS IMAGINE for this release, see the Issues Resolved section. This document is only an overview and does not provide all the details about the product's capabilities. See the online help and other documents provided with ERDAS IMAGINE for more information. 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. ERDAS IMAGINE PRODUCT TIERS ERDAS IMAGINE® performs advanced remote sensing analysis and spatial modeling to create new information. In addition, with ERDAS IMAGINE, you can visualize your results in 2D, 3D, movies, and on cartographic-quality map compositions. The core of the ERDAS IMAGINE product suite is engineered to scale with your geospatial data production needs. Optional modules (add-ons) providing specialized functionalities are also available to enhance your productivity and capabilities. IMAGINE Essentials® is the entry-level image processing product for map creation and simple feature collection tools. IMAGINE Essentials enables serial batch processing. IMAGINE Advantage® enables advanced spectral processing, image registration, mosaicking and image analysis, and change detection capabilities. IMAGINE Advantage enables parallel batch processing for accelerated output. IMAGINE Professional® includes a production toolset for advanced spectral, hyperspectral, and radar processing, and spatial modeling. Includes ERDAS ER Mapper. IMAGINE Photogrammetry maximizes productivity with state-of-the-art photogrammetric satellite and aerial image processing algorithms. May 31, 2018 4 New Platforms NEW PLATFORMS ARCGIS 10.6 ERDAS IMAGINE 2018 Update 1 has been tested and declared Supported when using an installed and licensed version of ArcGIS 10.1 through 10.6 in order to provide Geodatabase support libraries. Alternatively, the IMAGINE Geodatabase Support component (based on ArcGIS Engine 10.5) can be installed to provide Geodatabase support. NEW LICENSING ERDAS IMAGINE 2018 was delivered with version 16.5.0.11 of the Hexagon Geospatial Licensing 2018 tools. However it is strongly recommended that all ERDAS IMAGINE customers upgrade to v16.5.0.15 (or higher). The appropriate download can be found on the Downloads section of the Hexagon Geospatial web site: https://download.hexagongeospatial.com/downloads/other/geospatial-license-administrator-2018 Hexagon Geospatial Licensing 2018 v16.5.0.15 is also integrated into the ERDAS IMAGINE 2018 Update 1 installer, so any computer where you install Update 1 should also have any existing installation of Hexagon Geospatial Licensing 2018 automatically updated to v16.5.0.15. If in doubt, refer to Windows’ Add or Remove Programs utility to determine the currently installed version. NEW TECHNOLOGY GPU ACCELERATION FOR THE NNDIFFUSE PAN SHARPENING OPERATOR The Nearest-neighbor diffusion-based (NNDiffuse) algorithm, originally developed by Sun, Chen and Messinger at Rochester Institute of Technology, is a state of the art pan sharpening technique, which
