The global bathymetry and topography grid at 15 Arc Sec is the latest iteration of the SRTM+ digital elevation model (DEM) where the "plus" indicates the addition of ocean bathymetry from shipboard soundings and satellite-derived predicted depths. This DEM is a global elevation grid with a spatial sampling interval of 15 arc seconds ...
Oct 6, 2021 · Open Topography is an online portal or clearing house or spatial data infrastructure for topographic data. Through a web-based interface, it provides access to everything from global DEM data like Shuttle radar topography mission (SRTM) data sets all the way through to state and national lidar collections.

Watch this video tutorial to learn how to perform vertical change detection on OpenTopography's web interface. As of late 2020, vertical differencing is enabled on over 60 dataset pairs that capture a number of processes including urban growth, vegetation change, river processes, earthquakes and landslides. 3D Differencing: Learn how to perform ...
Lidar (alternatively spelled LiDAR or LIDAR) is an acronym for Li ght D etection a nd R anging, a remote sensing method that uses laser light pulses to measure variable distances (aka ranges) to the Earth. Lidar is used to create high resolution three-dimensional representations of Earth's surface, including buildings, vegetation, and the ground.
