In the Web definitions can be found which define the DEM as a digital regularly spaced GRID and a DTM as a real three-dimensional model ( TIN ).

A DEM can be represented as a raster ( a grid of squares, also known as a heightmap when representing elevation ) or as a vector-based triangular irregular network ( TIN ).

Terrain is commonly modelled either using vector ( triangulated irregular network or TIN ) or gridded ( Raster image ) mathematical models.

Tyndall ( pronounced TIN '- duhl ) is a city in Bon Homme County, South Dakota, United States.

The limit is applied per Social Security Number ( SSN ) or Taxpayer Identification Number ( TIN ).

Also known as the Tax Identification Number ( TIN ), Federal Employer Identification Number ( FEIN ) or the Federal Tax Identification Number, the EIN is a unique nine-digit number assigned by the Internal Revenue Service ( IRS ) to business entities operating in the United States for the purposes of identification.

When the number is used for identification rather than employment tax reporting, it is usually referred to as a TIN, and when used for the purposes of reporting employment taxes, it is usually referred to as an EIN.

TNTlite is a free geospatial analysis system providing a complete fully featured Geographic information system, RDBMS, and automated image processing system with CAD, TIN, surface modeling, map layout and innovative data publishing tools.

TNTmips is a geospatial analysis system providing a fully featured GIS, RDBMS, and automated image processing system with CAD, TIN, surface modeling, map layout and innovative data publishing tools.

A Taxpayer Identification Number or TIN is an identifying number used for tax purposes in the United States.

In civil engineering and entertainment businesses, the most representations of land surface employ some variant of TIN models.

* and the Triangulated irregular network ( TIN ) data model represents geography as sets of contiguous, nonoverlapping triangles.

DTM-the digital terrain modelling tools for creation of TIN models from points or contours.

Contour lines and triangulated irregular networks ( TIN ) are used to represent elevation or other continuously changing values.

Interbusiness, Italy ’ s largest Internet network, was created and around the same time with TIN ( Telecom Italia Net ) and the first ISPs, Internet became a reality in Italy too.

** Has three line companies with switch, data, radio, and cable functionality, a headquarters company, and a Tactical Installation and Networking ( TIN ) company.

The digital elevation model ( DEM ) is a raster-based digital dataset of the topography ( hypsometry and / or bathymetry ) of all or part of the Earth ( or a telluric planet ).

The featured image shows a plot of a DEM dataset containing mountainous areas near Dunsmuir, CA.

It can be used to create DTM ( Digital Terrain Models ) and DEM ( Digital Elevation Models ) this is quite a common practice for larger areas as a plane can take in a 1km wide swath in one flyover.

A discrete element method ( DEM ), also called a distinct element method is any of family of numerical methods for computing the motion and effect of a large number of small particles.

Though DEM is very closely related to molecular dynamics, the method is generally distinguished by its inclusion of rotational degrees-of-freedom as well as stateful contact and often complicated geometries ( including polyhedra ).

Today DEM is becoming widely accepted as an effective method of addressing engineering problems in granular and discontinuous materials, especially in granular flows, powder mechanics, and rock mechanics.

* DEM allows a more detailed study of the micro-dynamics of powder flows than is often possible using physical experiments.

The DEM computing engine is written in C ++ and parallelised using MPI, permitting simulations of more than 1 million particles on clusters or high-end workstations.

* LAMMPS is a very fast parallel open-source molecular dynamics package with GPU support also allowing DEM simulations.

* LIGGGHTS is a code based on LAMMPS with more DEM features such as wall import from CAD, a moving mesh feature and granular heat transfer.

There is also a module dealing with the coupling between DEM and the Lattice Boltzmann Method ( LBM ).

* PASSAGE / DEM ( PASSAGE / DEM Software is for predicting the flow particles under a wide variety of forces.

There is no common usage of the terms digital elevation model ( DEM ), digital terrain model ( DTM ) and digital surface model ( DSM ) in scientific literature.

Other definitions equalise the terms DEM and DTM, or define the DEM as a subset of the DTM, which is also representing other morphological elements.

In the following the term DEM is used as a generic term for DSMs and DTMs.

A DEM implies that elevation is available continuously at each location in the study area.

* MechSys Although it was initially a package dedicated to the FEM method, nowadays it also contains a DEM module.

Digital elevation models ( DEM ) were also compiled, initially from topographic maps and stereographic interpretation of aerial photographs and then from satellite photography and radar data.

There are also definitions which equalise the terms DEM and DSM.

A much higher quality DEM from the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) instrument of the Terra satellite is also freely available for 99 % of the globe, and represents elevation at a 30 meter resolution.

MD can also be seen as a special case of the discrete element method ( DEM ) in which the particles have spherical shape ( e. g. with the size of their van der Waals radii.

The film also had limited distribution in Germany where it grossed DEM 367, 603 ($ 224, 520 ).

The DEM is also responsible for administering Texas ' AMBER Alert network.

DEM also contains a supply chain diagram tool for the logistic network of the company and of an enterprise function modelling diagram ".

The town also possesses an airport ( ICAO code HADD, IATA DEM ).
