Aerial laser scanning (ALS) dataset, Mount Itoupé, French Guiana, acquired on 7 and 8 August 2014.

The aerial laser scanning (ALS) dataset was acquired on 7 and 8 August 2014 in the framework of DynForDiv project. It covers mount Itoupé (altitude 830m above sea level) in French Guiana (total covered area = 72 km²). Based on sample tiles (45, 70,192, 201, 256), the mean emitted pulse density is ~12/m², and the mean echo density ~ 19/m². Lidar Riegl LMS Q560 aboard a plane operated by Altoa

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 5 reflected pulses with a nominal precision of 10cm. The mean point density is 17 points/m². 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\Inini\2014 4. Various further processing steps were carried out.
