ERDAS Imagine 8.4: A Free and Powerful Remote Sensing Software




Remote sensing is the science of acquiring and analyzing information about the Earth's surface and atmosphere from a distance, using sensors mounted on satellites, aircraft, or other platforms. Remote sensing can be used for various applications, such as land use and land cover mapping, environmental monitoring, disaster management, natural resource exploration, and more.

However, remote sensing data often require specialized software tools to process, analyze, and visualize them. One of the most popular and widely used software packages for remote sensing is ERDAS Imagine, developed by ERDAS Inc., a subsidiary of Hexagon AB.


What is ERDAS Imagine?




ERDAS Imagine is a geospatial data authoring system that provides tools for remote sensing, photogrammetry, and geospatial analysis. ERDAS Imagine can handle various types of data, such as raster, vector, lidar, radar, hyperspectral, thermal, and more. ERDAS Imagine can perform various operations on the data, such as image enhancement, classification, segmentation, change detection, feature extraction, orthorectification, mosaicking, 3D visualization, and more.


ERDAS Imagine also supports various data formats, standards, and protocols, such as GeoTIFF, JPEG2000, ECW, HDF5, NetCDF, OGC WMS/WFS/WCS/WMTS/GeoPackage/CoverageJSON/GeoJSON/GeoTIFF/COG/STAC/Zarr/TileDB/Cloud Optimized GeoTIFF (COG), GDAL/OGR/PROJ/GEOS/LibTIFF/LibJPEG/LibPNG/LibECW/LibHDF5/LibNetCDF/LibLZMA/LibZSTD/LibLERC/LibOpenJPEG/LibWebP/LibGIF/LibCharLS/LibKakadu/LibJP2KAK/LibJPEG-XR/LibJPEG-LS/LibJPEG-Turbo/LibPNG16/LibPNG-APNG/LibPNG-MNG/LibPNG-WebP/LibPNG-HEIF/LibPNG-AVIF/LibPNG-JXL/LibPNG-BPG/LibPNG-FLIF/LibPNG-PIK/LibPNG-FUIF/LibPNG-Guetzli/LibPNG-Leptonica/LibPNG-MozJPEG/LibPNG-Zopfli/, etc.


Why ERDAS Imagine 8.4?




The latest version of ERDAS Imagine is 2021.1, which was released in March 2021. However, this version requires a license to use and is not free. If you are looking for a free and powerful version of ERDAS Imagine that can run on Windows XP/Vista/7/8/10 (32-bit or 64-bit), you may want to try ERDAS Imagine 8.4 , which was released in 1999.


ERDAS Imagine 8.4 may be an old version, but it still has many features and functions that can meet your remote sensing needs. ERDAS Imagine 8.4 can handle most of the common data formats and standards at that time, such as TIFF/GeoTIFF/TIFF-LZW/TIFF-JPEG/TIFF-JPEG2000/TIFF-CCITT/TIFF-PackBits/TIFF-Deflate/TIFF-LZMA/TIFF-ZSTD/TIFF-LERC/TIFF-OpenJPEG/TIFF-WebP/TIFF-GIF/TIFF-CharLS/TIFF-Kakadu/TIFF-JP2KAK/TIFF-JPEG-XR/TIFF-JPEG-LS/TIFF-JPEG-Turbo/TIFF-PNG16/TIFF-PNG-APNG/TIFF-PNG-MNG/TIFF-PNG-WebP/TIFF-PNG-HEIF/TIFF-PNG-AVIF/TIFF-PNG-JXL/TIFF-PNG-BPG/TIFF-PNG-FLIF/TIFF-PNG-PIK/TIFF-PNG-FUIF/TIFF-PNG-Guetzli/TIFF-PNG-Leptonica/TIFF-PNG-MozJPEG/TIFF-PNG-Zopfli/, JPEG/JPEG2000/JPEG-XR/JPEG-LS/JPEG-Turbo/JPEG-MozJPEG/JPEG-Guetzli/, PNG/PNG16/PNG-APNG/PNG-MNG/PNG-WebP/PNG-HEIF/PNG-AVIF/PNG-JXL/PNG-BPG/PNG-FLIF/PNG-PIK/PNG-FUIF/PNG-Guetzli/PNG-Leptonica/PNG-MozJPEG/PNG-Zopfli/, GIF, BMP, PCX, PPM, PGM, PBM, XPM, ICO, CUR, ANI, RAS, SUN, SGI, PSD, TGA, IFF, RLA, RPF, PIC, CEL, CUT, PAL, CLP, XBM, XWD, WBMP, WAP, EMF, WMF, etc.


ERDAS Imagine 8.4 can also perform various image processing and analysis tasks, such as image enhancement (contrast stretching, histogram equalization, filtering, sharpening, smoothing, etc.), image classification (supervised and unsupervised classification using various algorithms and methods), image segmentation (region growing and merging using various criteria and thresholds), image registration (geometric correction and co-registration using various models and methods), image fusion (pan-sharpening and multi-sensor fusion using various techniques and algorithms), image change detection (difference image and post-classification comparison using various methods and measures), image feature extraction (edge detection and object detection using various operators and techniques), image orthorectification (ortho-correction using various models and methods), image mosaicking (seamless mosaicking using various techniques and algorithms), image 3D visualization (perspective view and fly-through using various options and settings), etc.


ERDAS Imagine 8.4 also has a user-friendly interface that allows you to easily access the tools and functions you need. You can use the menu bar, the toolbar, the toolbox, the layer manager, the viewer window, the status bar, the command line, the dialog boxes, the wizards, the help system, etc. to interact with the software. You can also customize the interface according to your preferences and needs.
