SOCET SET is a software application that performs a variety of functions related to photogrammetry. It is developed and published by BAE Systems.
Features
SOCET SET inputs digital aerial photographs, take in stereo (binocular) fashion, and from those photos it automatically generates digital terrain data, digital feature (vector data), and orthorectified images (called Orthophotos). The output data is used by customers to create digital maps, and for mission planning and targeting purposes.
The source images can come from film-based cameras, or digital cameras. The cameras can be mounted in an airplane, or on a satellite. A key requirement of the imagery is that there must be 2 or more overlapping images, taken from different vantage points. This "binocular" characteristic is what makes it mathematically possible to extract the 3-dimensional terrain and feature data from the imagery. See Imaging Spectroscopy for more details on stereo image viewing.
A key step, involving very complex least squares mathematics, is Triangulation which determines exactly where the cameras were positioned when the photographs were taking. Photogrammetrists that contributed to SOCET SET's Triangulation include Scott Miller, Bingcai Zhang, John Dolloff, and Fidel Paderas. If the quality of the triangulation is poor, all subsequent data will have correspondingly poor positional accuracy.
The most recent major version, released in 2006, is version 5.3.
Stereo Display
SOCET SET, like all high-end photogrammetry applications, requires a stereo display to be used to its fullest potential. Although SOCET SET can run and generate all its products on a computer with only a conventional display, a typical user will require a stereo display to view the digital data overlaid on the imagery. Interactive (manual) quality assurance requires this capability.
Hardware companies that manufacture hardware for stereo image display include:
File formats
SOCET SET has the ability to read and write many imagery formats: VITec, Sun Raster, TIFF, TIFF 6.0 (Raster, Tiled, Tiled JPEG, and LZW), JFIF, NITF 2.0, NITF 2.0 JPEG, NITF 2.1, NITF 2.1 JPEG, ERDAS IMAGINE®, JPEG 2000, Targa, COT, DGN, USGS DOQ, MrSID, Plain Raster
SOCET SET has the abilithy to read many different terrain data formats, including: DTED, USGS DEM, ASCII (user-defined), LIDAR LAS, ArcGrid, SDTS, NED, GSI, GeoTIFF
Vector formats supported include: DXF, Shapefile, ASCII (ArcGen), ASCII, TOPSCENE
History
Development started as a Research and Development project around 1989, with Jim Gambale as the sole developer. At the time, the parent corporation was GDE Systems (formerly a subsidiary of General Dynamics). The hardware platform was a PC running Interactive Unix.
After his initial prototype (running Interactive Unix on a PC platform) proved successful, a larger R&D effort was initiated in 1990, led by Herman Kading. One of the primary accomplishments of this effort was to migrate the product to various UNIX Platforms, including Sun, SGI, HP, and IBM.
Key technical knowledge was provided by Helava Inc, a company based in Detroit Michigan that specialized in photogrammetry. Helava employees Scott Miller, Janis Thiede, and Kurt Devenecia brought in-depth experience in the field.
Leadership of the project passed to Neal Olander around 1992, and after this time, SOCET SET (which before then was only sold to government customers) began to be distributed commercially. Around 1994, SOCET SET was migrated to the Microsoft Windows operating system, although the Unix system continued to be supported as well.
Key technical skills were provided by Dave Miller, Dave Mayes, Jim Colgate, and Bingcai Zhang. Dave Miller was especially noteworthy because of his special exepertise with stereo displays.
Release history
- v4.1 - Sept 1998
- v5.0 - Sept 2003
- v5.3 - June 2006
Alternatives
The chief competitor to SOCET SET is Intergraph, which is also a leader in the field of photogrammetry.
Other related companies that have a limited amount of photogrammetry in their applications include ESRI (a GIS product) and ERDAS (owned by Leica Geosystems) which is primarily a remote sensing application.
