Editor's Notes
- #4 LiDAR – Light Detection and Ranging . Basically, this technology involves directing laser beams from an airplane to the earth surface, and measuring the length of time it takes for the laser beams to reflect back to a detector on the airplane. This data can be used to quantity features on the surface such as trees and buildings as well as the actual elevation map of the earth surface.Computer technology is used to segregate the laser returns to first returns (used for features other than the ground surface, such as trees) and bare earth returns used for an elevation map.
- #5 Examples of lidar applications:Flood mapZone maps for precision agricultureConstructionCommunity development
- #6 Since the data is large, computers used for managing lidar require much computer storage space and computing power.The data is available for the Red River Valley drainage area. The data can be downloaded from the Internet without charge to the user.Lidar requires some kind of a geographic information systems (GIS) computer program. Most operate on your computer, but some operate online.Several agricultural consultants companies provide basic viewers without charges. However, programs that actually allow users to export lidar-derived GIS layers generally are not free.
- #7 Data is available for the US portion of the Red River Basin from the USGS or the International Water Institute’s Websites.The US Army Corps of Engineer – St Paul website has some lidar data for the Manitoba Red River Valley drainage area: http://www.mvp.usace.army.mil/
- #8 This site allows users to find areas by township and range, towns, or by zooming in to a specific area on their map.
- #9 John, We have been working with several partners on LiDAR data collects during2010 and 11 for the james river basin and surrounding areas of ND and SD.Unfortunately none of the data has been delivered yet. We are expecting data to begin showing up in the next 30-60 days. Please check back then.
