PCI Geomatica is a remote sensing desktop software package for processing earth observation data, designed by PCI Geomatics. The latest version of the software is Geomatica 2017. Geomatica is aimed primarily at faster data processing and allows users to load satellite and aerial imagery where advanced analysis can be performed. Geomatica has been used by many educational institutions and scientific programs throughout the world to analyze satellite imagery and trends, such as the GlobeSAR Program, a program which was carried out by the Canada Centre for Remote Sensing in the 1990s.
A very popular edition of Geomatica is known as Freeview, which permits users to load multiple types of satellite images as well as geospatial data that is stored in different formats. The software is available for download over the web, and has registered several thousands of downloads. Geomatica is one of several software packages available to the educational, commercial, and military users.
ERDAS Imagine is a remote sensing application with raster graphics editor abilities designed by ERDAS for geospatial applications. The latest version is 2015. Imagine is aimed mainly at geospatial raster data processing and allows users to prepare, display and enhance digital images for mapping use in geographic information system (GIS) and computer-aided design (CAD) software. It is a toolbox allowing the user to perform numerous operations on an image and generate an answer to specific geographical questions.
By manipulating imagery data values and positions, it is possible to see features that would not normally be visible and to locate geo-positions of features that would otherwise be graphical. The level of brightness, or reflectance of light from the surfaces in the image can be helpful with vegetation analysis, prospecting for minerals etc. Other usage examples include linear feature extraction, generation of processing work flows (spatial models in Imagine), import/export of data for a wide variety of formats, orthorectification, mosaicking of imagery, stereo and automatic feature extraction of map data from imagery.
Before the ERDAS Imagine Suite, ERDAS, Inc. developed various products to process satellite imagery from AVHRR, Landsat MSS and TM, and Spot Image into land cover, land use maps, map deforestation, and assist in locating oil reserves under the product name ERDAS. These older ERDAS applications were rewritten from Fortran to C and C++ and exist today within the Imagine Suite, which has grown to support most optical and radar mapping satellites, airborne mapping cameras and digital sensors used for mapping.

What is SNAP?

SNAP is an open source common architecture for ESA Toolboxes ideal for the exploitation of Earth Observation data.

What does the acronym SNAP stand for?

SNAP is the SeNtinel’s Application Platform.

How is SNAP licensed?

SNAP is licensed under the GNU GPL v3

What is the minimum required hardware to run SNAP on a laptop or desktop?

It is recommended to have at least 4GB of memory. To run the 3D WorldWind View, it is recommended to have a 3D graphics card with updated drivers. SNAP will work on 32 and 64 bit Windows, Mac OS X and Linux.

How can I get WorldWind to work? I see a blank window in the World View.

To use the WorldWind World Map, a 3D video card with updated drivers is necessary. Update your video card drivers. (How to update windows drivers) (ATI/AMD – Nvidia – Intel). Some known issues exist with using WorldWind within a virtual machine such as VirtualBox.

How can I move the .snap user application data folder somewhere else?

By default SNAP creates a \.snap (~/.snap on Linux). The .snap folder is used to store temporary data such as preferences, logs, downloaded DEM files etc. Some users have a small quota on their home folder and would like to change the location of this folder.
Edit the file SNAPInstallFolder\etc\snap.properties and change the line
AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk,^[1] AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.^[2] Prior to the introduction of AutoCAD, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.^[3] Since 2010, AutoCAD was released as a mobile- and web app as well, marketed as AutoCAD 360.
AutoCAD is used across a wide range of industries, by architects, project managers, engineers, graphic designers, and many other professionals. It was supported by 750 training centers worldwide in 1994.^[1]
AutoCAD was derived from a program begun in 1977 and released in 1979^[4] called Interact CAD, also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Mike Riddle.^[5][6]
The first version by Autodesk was demonstrated at the 1982 Comdex and released that December.^[7] As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide.^[8] The 2018 release marked the 32nd major release of AutoCAD for Windows. The 2014 release marked the fourth consecutive year of AutoCAD for Mac.
The native file format of AutoCAD is .dwg. This and, to a lesser extent, its interchange file format DXF, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange.^{[citation needed]} AutoCAD has included support for .dwf, a format developed and promoted by Autodesk, for publishing CAD data.
Autodesk's logo and, respectively, AutoCAD icons have changed for several versions through the years.
