The company also produces Contour Maps from the data collected off Aerial Surveyies. Those Contour Maps shows the hierarchy of the site and shows the heights and decreases and level of gradation, by any terminator starts from 25 cm and extends to several meters and according to the request of the client, and can use the contour map with the aerial image and thus appear as a background image of the contour map As confirmation of the contour lines on the ground.
A representation of the world using points, lines, and polygons. These data are created by digitizing the base data. They store information in x, y coordinates. Vectors models are used to store data, which have discrete boundaries like country borders, land parcels and roads. Vector models are useful for storing data that has discrete boundaries, such as country borders, land parcels, and streets.
3D Point Cloud
In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and often are intended to represent the external surface of an object. For example, in Aerial Survey and GIS, point clouds are one of the sources used to make digital elevation model of the terrain .They are also used to generate 3D models of urban environment.
