For the first time, a number of features and design principles of the GENA platform and model toolboxes have been publicly presented in a joint paper co-authored by Dr. Ismael Colomina, Dr. Marta Blázquez, Dr. José A. Navarro (Institue of Geomatics, IG) and Mr. Jaume Sastre (GeoNumerics, GN). The paper discusses the relevance of extensible network adjustment programmes in view of the current wave of sensor technology and the needs for rapid sensor prototyping (in the sensor design phase), rapid sensor orientation and calibration modelling (in the sensor commercialization phase) and accurate sensor orientation and calibration (in the sensor exploitation phase).
In the paper, the need for software tools that allow for rapid and safe development of models -with protection of intellectual property rights if desired- is translated into software specifications of simplicity, genericity and extensibility that, in turn, lead to architectural constructs where the general robust non-limear least-squares (RNLLS) functionality is concentrated in a software platform and the specific sensor features (models) are concentrated on reusable software components.
With the contributions of the paper, the authors intend to promote the use of modern software engineering and abstract generic modelling in photogrammetry and remote sensing.
GENA, Generic Extensible Network Approach is GeoNumerics' robust non-linear least-squares generic network adjustment engine. With GENA, measurements of geodetic networks, photogrammetric blocks and remote sensing blocks can be adjusted. Observations of different types can be arbitrarily combined into single large adjustments for model-based parameter determination purposes. GENA has been used for geometric and radiometric modelling from terrestrial and aerial surveys, ranging from LiDAR to thermal sensing, to optical camera prototyping.
The International Society for Photogrammetry and Remote Sensing (ISPRS) is a non-governmental organization devoted to the development of international cooperation for the advancement of photogrammetry and remote sensing and their applications. The Society operates without any discrimination on grounds of race, religion, nationality, or political philosophy. The ISPRS was founded in 1910 by its first President, Eduard Dolezal, under the name International Society for Photogrammetry (ISP) that was extended to ISPRS in 1980.
The ISPRS organizes its general congress on a quadrennial basis. The XXII ISPRS Congress brought together more than 2000 participants and took place in Melbourne, VIC, Australia, from August 24th to September 1st, 2012.
