Supplemental information
The aerial survey was conducted over 16 flights between September 26, 2015 and October 17, 2016 using Leica ALS70-HP 500kHz Multiple Pulse in Air (MPiA) LiDAR sensor system aboard a Piper Navajo PA-31 aircraft.

ATLIS combined data from two projects to create the dataset for this project: City of Winnipeg Spec and Southern Manitoba Spec. The two projects were collected and processed independently using these mission specifications:

CITY OF WINNIPEG:
Above Ground Level (AGL) Flying Height: 950m
Mean Sea Level (MSL) Flying Height: 1150m
Average Ground Speed: 140kts
Scan Rate: 53.4Hz
Pulse Rate: 500kHz
Field of View: 45°
Lateral Overlap: 30%

SOUTHERN MANITOBA:
Above Ground Level (AGL) Flying Height: 1500m
Mean Sea Level (MSL) Flying Height: 1700m
Average Ground Speed: 150kts
Scan Rate: 46.9Hz
Pulse Rate: 343.4kHz
Field of View: 50°
Lateral Overlap: 30%

Data Quality 

Scope of quality information


Data quality report - Absolute external positional accuracy
Dimension horizontal


Quantitative test results
+/- 1m



Evaluation method
Ground control was observed and Cannet OBNK, VO23, PLAP, PLUM, SNF2, STB2, 84R162, V021, V022, WINN, V081, V082, reference stations was used and Atlis Geomatics base station AGIB, to reference ABGPS. Accuracy value is based on the aggregate error inherent in the production process.

Lineage 

Process step
Description
Lidar was acquired on Oct 24, Nov 13, Nov 14, Nov 15, Sept 29, 2015 and Apr 27, May 4, May 18, May 21, July 25, July 27, July 28, July 29, Oct 17, 2016. The acquired Lidar data was part of another project that was encompassed with the Seine-Rat River Conservation District area of interest. Lidar is calibrated with NAD83 (CSRS) and CGVD28 datum using UTM 14 North projection and is classified. The classified data was used to create the DEM using the following classes: 2 (all ground features that exist). DEM was created at a 1m resoultion and then exported out as a Geotiff with 32 bit floating elevations. Images were cut into tiles based on the lidar index .
