Statement: 1. All data was acquired by Altoa flying an airplane at the altitude of ~600 (?) meters above ground level. The embarked system was composed of a scanning laser altimeter with a rotating mirror mechanism (Riegl LMS-Q560). The wave length used was 1550 nm. The scanning angle was around +/-20°. The laser recorder up to 7 reflected pulses with a nominal precision of 10cm. Ground point filtered by ALTOA who also provided DTM. 2. Delivery of the data in LAS 1.2 format. 3. The tiled las data are stored in \\forestview01\ALS\Trinité\2014 4. Various further processing steps were carried out. Please get in touch with a point of contact
