Laser Altimeter Experiences at Ibiza Island, Cape of Begur and Barcelona (spain)

One airborne calibration campaign with a Partenavia P-68 (ICC) carrying an Optech Lidar ALTM-3025 was made in June 16, 2007, overflying l’Estartit harbour. Measurements with a GPS Buoy were made during the experience and a GPS reference station was installed in Aiguablava complementing the CATNET network of the GPS Reference Stations of the ICC. A DSM of l’Estartit harbour area was derivedin the first results from the campaign. A second campaign has been made on October 12, 2007 with a Cessna Caravan 2083 (ICC) overflying the l’Estartit area at night about the same time that ICESat, for possible intercalibration of the two altimeters. An anlysis of the ICESat overflyings at the GLAS laser observation periods L3g, L3h and L3i near Ibiza and l’Estartit harbours is made. These campaigns were supported by the Spanish Ministery of Science and Technology under projects of the National Space Program ref: ESP2005-05829 and ESP2005-25306-E.
