ALS data were acquired 2005-09-04 using the Leica ALS40 airborne laser scanner flown at an altitude of 2740 m with a ± 20 degree field of view and a maximum pulse repetition frequency of 32 kHz. The average sampling density was 0.46 points per square metre. The data uses the NAD83 (CSRS) / UTM Zone 18N horizontal datum and the vertical datum is CGVD28. The data included in this package have been harmonized with other ALS acquisitions at PRF to enable height growth assessment. Details on the harmonization approach applied are provided in Riofrio et al (2022). DOI: http://dx.doi.org/10.1139/cjfr-2022-0055.

ALS data were acquired 2016-07-20 using a Teledyne Optech Titan multi-wavelength scanning system flown at an altitude of 1100 m with a ± 20 degree field of view and a maximum pulse repetition frequency of 375 kHz. Three wavelengths were acquired: SWIR (1550 nm), NIR (1064 nm), and GREEN (532 nm). The average sampling density was 5 points per square metre for the NIR. The data uses the NAD83 (CSRS) / UTM Zone 18N horizontal datum and the vertical datum is CGVD28. The data included in this package is the NIR band only. These data have been harmonized with other ALS acquisitions at PRF to enable height growth assessment. Details on the harmonization approach applied are provided in Riofrio et al (2022).

ALS data were acquired 2018-07-02 using the Leica SPL 100 scanning system flown at an altitude of 3760 m with a ± 15 degree field of view and a maximum pulse repetition frequency of 60 kHz.The Leica SPL 100 laser operates in the green wavelength (532 nm). The average sampling density was 32 points per square metre. The data uses the NAD83 (CSRS) / UTM Zone 18N horizontal datum and the vertical datum is CGVD28.The data included in this package have been harmonized with other ALS acquisitions at PRF to enable height growth assessment.
