The Buckeye system relies on two major components: the electro-optical (EO) imaging system and the LIDAR system. The EO system utilizes a CCD camera and an embedded imaging computer to obtain the desired images while accounting for the movement of the aerial system to which it is attached.
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
The United States National Water and Climate Center collects and disseminates water resources and climate data. [1] It is part of the Natural Resources Conservation Service of the United States Department of Agriculture (USDA). The offices are located in Portland, Oregon, near Lloyd Center. [2] Services include:
The Army Geospatial Center (AGC) [2] (formerly Topographic Engineering Center (TEC)) is a Major Subordinate Command of the United States Army Corps of Engineers. [3] It is located in Alexandria, Virginia, within the Humphreys Engineering Center adjacent to the Fort Belvoir military reservation.
A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
National Geophysical Data Center: All free data from the NGSC. Includes elevation models, land cover, seismology, etc. The Geospatial Platform: Search for and download a wide variety of datasets from this portal developed by the member agencies of the Federal Geographic Data Committee through collaboration with partners and stakeholders.
Direct Web Remoting, or DWR, is a Java open-source library that helps developers write web sites that include Ajax technology. [1] It allows code in a web browser to use Java functions running on a web server as if those functions were within the browser. The DWR project was started by Joe Walker in 2004, 1.0 released at August 29, 2005.
Global Ecosystem Dynamics Investigation (GEDI, pronounced / ˈ dʒ ɛ d aɪ /) is a NASA mission to measure how deforestation has contributed to atmospheric CO 2 concentrations. [1] [2] A full-waveform LIDAR was attached to the International Space Station to provide the first global, high-resolution observations of forest vertical structure.
