Digitalization of aerial photography for digital data capture (France) (1995-1997)

The appearance of photogrammetric systems that work on images is giving rise to agreements to digitalize the analogical information contained on aerial photographs. The tool for performing this task is the photogrammetric scanner, in the case of the ICC, the Intergraph PS1 and TDSCAN systems. This systems are capable of digitized images with differents resolutions and with a contrasted accuracy of 4 µm. Once the aerial photographs are digitalized, it is possible to visualize them by means of 2D or 3D photogrammetric stations, perform the same tasks as could be performed with the analytical systems and also take advantage of the capacity for process automation made posible by working with digital tools, such as the automatic extraction of terrain elevation models or the semi-automatic survey of cartographic objects, for example.

GEOCAL (1995-1997)

Research project whose aim is the periodic geometric in flight calibration of the MOMS-2p camera throughout the mission on which it will be on board the PRIRODA module of the MIR orbital station. After studying the characteristics of the sensor and the associated data provided by the DLR, the images orientation model will be established, which will be validated using images from previous missions, and a geometric in flight calibration model will be defined.

LPFICC (1995-1997)

Research project to evaluate the cartographic potential of the MOMS-type three line sensors using a software prototype to perform image orientation by means of point transfer and orbit determination techniques. The stages of the project were: construction of the prototype; aerial triangulation of a block of MOMS images over Catalonia; evaluation of the cartographic potential.

Evaluation of the photogrammetric capacity of the MOMS (Bolivia) (1995-1996)

The MOMS sensor is an instrument that combines the capacity to capture multispectral images with the capacity to capture stereoscopic images. This latter facility led to agreements with the German DLR in order to obtain images captured during the flight of the space shuttle over Bolivia, and with the Instituto Geográfico Militar de Bolivia in order to obtain pass and test points for the orientation of these images. The aims of the work of the ICC are: to adapt a geometric deformation model of the sensor, extract the terrain elevations model through the stereoscopic capacity of the sensor and construct an orthoimage of the area.

Venezuela (1994)

Project to demonstrate the advantages inherent in the use of aerial control for the aerial triangulation of a photogrammetric block, especially in areas where the determination of ground control points is difficult and extremely costly. The project was conducted in the following stages: establishment of a reference station for subsequent processing of the aerial GPS (Global Positioning System) observations; postprocessing of the GPS data (aerial reference station), and aerial triangulation of the block. Adjustment of a photogrammetric block of 650 photograms at 1:60,000 scale with only 17 ground control points.

Geometric test of the ERS-1 images over Frankfurt (1993)

Participation in the first phase of the OEEPE-GeoSAR test, which consisted in comparing geometric models for SAR (Synthetic Aperture Radar) images from the ERS-1 satellite. Each of these models contained a set of constants characteristic of the platform and the sensor and another set of parameters which had to be adjusted with external information, normally pass points located on the ground. For the comparison, a same set of data was used, consisting of an image of Frankfurt, the elevations model of the area and some maps for the location of pass and test points.

An assessment of the European technical capability for the treatment and interpretation of satellite earth observation data (1991)

The aim of this project was to promote a higher degree of development of the satellite telecommunications industry, to determine the reasons behind the scant activity of companies specialising in remote sensing in Europe and to provide suggestions aimed at optimising the capacity of the European groups to extract relevant information from the Earth observation satellites. The considerable investment that European countries make in order to launch and monitor these satellites is not matched by the demand for the images that are produced, unlike what has occurred in the field of satellite telecommunications.

Urgell test - Aerial triangulation with GPS (1990-1992)

AT-DTM: Aerial Triangulation with Digital Terrain Model (1989-1990)

Project to investigate aerial triangulation supported by terrain elevation models. From the simulations made it was deduced that the use of Digital Terrain Models (DTM) in aerial triangulation is advisable in applications based on satellite images, when control points are too expensive, and also in applications that require DTM for other uses.
