The word DTM stands for Digital terrain mapping. Digital terrain mapping is simply nothing but the 3d view of the ground terrain landscape. This is used particularly for creating map such as relief map, climatic changes, aerial photograph etc. There are various applications of digital terrain mapping (DTM).

The main objective for the discovery of this technology is for the purpose of creating map so that this will enable the researchers and other people to have a deep insight about areas that is under study for them.

The researchers can analyze the areas that they want to know in a deeper sense when they study about a particular place or area to know about the resources present in the area. When you look at the map which is developed by the digitals terrain mapping technology you can able to observe that it comprises of many irregular shaped triangles or successive squares and this determines the eminence of the map which you make by using the digitals terrain mapping technology.

The map that is created by Digital terrain mapping will not show the forest and the other cities are eliminated from it by using some software or by editing manually. Topographical map are generally created by using this method. From the topographical map one can able to gather a lot of the information about a particular zone or the area.

If they are able to turn their cons into pros it will facilitate them to gain more profit. This technology is considered as an asset for the civil group of the people as with this they can find all the information which they need about the areas and also about the elevations of the areas in which they plan to erect the building.

Elevation shape is generally developed only by this method which will help people to get a better insight. This 3d model which they are making will make their planning very easier. Insurance companies now days are using this method in order to estimate the level of the risk that is associated with the area regarding the flood which plays a crucial role as this in turn will help them to calculate the premium level of the customers.

This is one of the valuable tools that the researchers use when they are planning to make a study of the resources that are hidden underground. This is a great asset for the civil engineers to build a construction.

One can state numerous applications for digital terrains mapping method. This is really one of the wonderful discoveries made by the human beings to know more about the mother earth
