A Digital Surface Model (DSM) is an elevation model that includes the tops of buildings, trees, powerlines, and any other objects. Commonly this is seen as a canopy model and only 'sees' ground where there is nothing else overtop of it.
A Digital Elevation Model (DEM) is a 'bare earth' elevation model, unmodified from its original data source (such as lidar, ifsar, or an autocorrelated photogrammetric surface) which is supposedly free of vegetation, buildings, and other 'non ground' objects.
A Digital Terrain Model (DTM) is effectively a DEM that has been augmented by elements such as breaklines and observations other than the original data to correct for artifacts produced by using only the original data. This is often done by using photogrammetrically derived linework introduced into a DEM surface. An example is hydro-flattening commonly seen in elevation models done to FEMA specificationsl

EarthOnDrive has put together a team of electronic & systems experts, remote sensing and photogrammetric software engineers, and signal processing engineers, and has developed the Drone Swarm Mapping technology, consisting of 40 UAV Drones, able to mount thermal SWIR and FLIR and Color camera sets onto a mapping grid of over 1 Mile by 1 Mile.
Projects that we will be deploying our swarm mapping technology on are mining and mineral mapping, large solar panel cluster assessments, griding technologies, construction site analysis, industrial on-site assessment and analysis, infrastructure p..
Tererra Incorporated has integrated newest hardware technologies together with custom operating system enhancements to deliver an accelerated storage solution that is very cost effective. Many companies would like to invest heavily in 10G, 40G, or even 56G network topographies in 2015 and 2016. This customer demand also requires a cost effective storage solution which can handle these speeds. Switch manufacturers are making this a cost effective investment with newest pricing strategies and affordable switches and network cards. Storage manufacturers however, are not effectively targeting cust..

We are pleased to announce the complete and 100% cloud free data over all of the European Union in 2016. The data has been amassed through five years of mapping and project work. It is delivered as GeoTIFF on more than 10TB of hard drives, with a WGS84 and Geodetic datum and projection. We can grid-n-tile the data as you like, in a variety of geospatial file formats.
