Business Solutions - Perth Metro LiDAR data
LiDAR (Light Detection And Ranging) is an increasingly popular remote sensing technology that uses light in the form of a pulsed laser (typically from an aircraft) to measure 'ranges', thereby being able to accurately calculate distances and elevations in a 3D environment. Landgate commissioned a LiDAR capture over the 'built up' areas of the Perth metropolitan area between the summer of 2021 and autumn of 2022. This supplements previous captures undertaken in recent years in the more remote regions - usually in support of state and local government initiatives. As the State's custodian of elevation data, Landgate makes its Capture WA funded LiDAR acquisitions available for use by state & local governments and industry.

Quebec lidar data
공공데이터포털
A lidar dataset (*light detection and ranging*) is a collection of 3D points represented in the form of a point cloud, generated from laser surveys (airborne). Remote sensing by airborne laser or lidar refers to a remote sensing or optical measurement technology based on the analysis of the properties of laser light returned to its emitter. The coordinates of the lidar points correspond to the precise positions where the laser pulses emitted by the lidar sensor have been reflected by objects or surfaces. In other words, each lidar spot represents a specific location where the light beam touched a surface and returned to the sensor. These coordinates are expressed in three dimensions (X, Y, Z) and make it possible to create very detailed and accurate representations of the terrain. In particular, lidar data allows: * to generate, among other things, numerical terrain (DTM) and surface (MNS) models; * to visualize the territory in perspective; * to perform three-dimensional spatial analyses for various needs, including: * the identification of areas potentially exposed to landslides and bank erosion; * landslide modeling; * the production of by-products and analyses of forest sectors; * the delimitation of flood zones. These datasets are the result of various intergovernmental collaborations, in particular with several ministries of the Government of Quebec, as well as with the federal government and the municipal sector. The geographic coverage corresponds to the information available on the download map and will be improved according to the availability of new data. In most cases, the data shown on this map corresponds to classified data. In the absence of classified data, but in the presence of raw data, it is the latter that will be presented on the map.

Lidar Elevation
공공데이터포털
Light Detection and Ranging (lidar) is a technology used to create high-resolution models of ground elevation with a vertical accuracy of 10 centimeters (4 inches).  rnrnFEMA collects lidar elevation data to support flood mapping. USGS is the primary Federal steward of lidar data. FEMA archives lidar data for FEMA projects where USGS does not manage the Lidar data collection. rnrnDatapoints include ground elevation models and vertical metrics for ground elevation.
