SOCET SET is a software application that performs functions related to photogrammetry. It is developed and published by BAE Systems. SOCET SET was among the first commercial digital photogrammetry software programs. Prior to the development of digital solutions, photogrammetry programs were primarily analog or custom systems built for government agencies.

Features

SOCET SET inputs digital aerial photographs, taken in stereo (binocular) fashion, and from those photos it automatically generates a digital elevation model, 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 two 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.

A key step, involving very complex least squares mathematics, is triangulation which determines exactly where the cameras were positioned when the photographs were taken. Photogrammetrists that contributed to SOCET SET's Triangulation include Scott Miller, Bingcai Zhang, John Dolloff, and Fidel Paderes. If the quality of the triangulation is poor, all subsequent data will have correspondingly poor positional accuracy.

The most recent major version, released in 2011, is version 5.6.

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.

File formats

SOCET SET has the ability to read and write the following 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 ability to read 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.

Applications

SOCET SET, like some photogrammetry tools, is used for the following applications:

About half of SOCET SET users are commercial, and half are government/military.

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 the prototype 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 UNIX Platforms, including Sun, SGI, HP, and IBM.

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 1996, SOCET SET was migrated to the Microsoft Windows operating system, although the Unix system continued to be supported as well.

Technical skills were provided by Tom Dawson, Kurt Reindel, Dave Mayes, Jim Colgate, Bingcai Zhang and Dave Miller.

Future

Starting in 2008, SOCET SET photogrammetric functionality is migrating to the next generation product, SOCET GXP (Geospatial eXploitation Product).

Meaning of SOCET SET

SOCET SET is an acronym that stands for SOftCopy Exploitation Toolkit. The phrase is a play on the actual tool socket set.

Release history

Alternatives

The chief competitor to SOCET SET is the Leica Photogrammetry Suite (aka LPS, owned by ERDAS), INPHO, PHOTOMOD and Intergraph, which are also leaders in the field of photogrammetry.

Other related applications that have some photogrammetry functionality include ArcGIS, ENVI, and ERDAS IMAGINE, all of which are primarily GIS or remote sensing applications.

A coverage is the digital representation of some spatio-temporal phenomenon. ISO 19123 provides the definition:

Remote sensing Acquisition of information at a significant distance from the subject

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about the Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines ; it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others.

A GIS file format is a standard of encoding geographical information into a computer file. They are created mainly by government mapping agencies or by GIS software developers.

Photogrammetry Taking measurements using photography

Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.

Orthophoto Geometrically corrected aerial photograph

An orthophoto, orthophotograph or orthoimage is an aerial photograph or satellite imagery geometrically corrected ("orthorectified") such that the scale is uniform: the photo or image follows a given map projection. Unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief, lens distortion, and camera tilt.

Image file formats are standardized means of organizing and storing digital images. An image file format may store data in an uncompressed format, a compressed format, or a vector format. Image files are composed of digital data in one of these formats so that the data can be rasterized for use on a computer display or printer. Rasterization converts the image data into a grid of pixels. Each pixel has a number of bits to designate its color. Rasterizing an image file for a specific device takes into account the number of bits per pixel that the device is designed to handle.

3D scanning

3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance. The collected data can then be used to construct digital 3D models.

MrSID is an acronym that stands for multiresolution seamless image database. It is a file format developed and patented by LizardTech for encoding of georeferenced raster graphics, such as orthophotos.

Triangulated irregular network

A triangulated irregular network (TIN) is a representation of a continuous surface consisting entirely of triangular facets, used mainly as Discrete Global Grid in primary elevation modeling.
