TcpMDT Images
Adjustment, management and transformation of images integrated in MDT
This CAD application allows you to perform all kinds of operations on digital images, georeferenced or not, in a wide variety of formats. It is designed especially for the needs of Surveying, Civil Engineering, Architecture or Archaeology projects, in which it is common to work with aerial photographs, orthoimages and scanned maps in combination with vector drawings.

Description
This module is designed for needs of projects involving Land Surveying, Civil Engineering, Architecture, Archaeology etc. in which it is frequent to work with different types of images in combination with vector drawings.
Orthophotos
MDT Images automatically inserts in their real position on the drawing a series of orthophotos in the most usual formats.
Aerial Photos and Scanned Maps
There are several options for georeferencing images, assigning them real terrain coordinates.
The simplest is to draw reference lines connecting known points on the image to points on the drawing. For more complex cases marks can be inserted with a name and subsequently link them to topographic points.
Photos with Position
MDT Images also insert photos at its own location if they have been taken by smartphones and cameras with GPS. Each photo is automatically linked to a topographic point and they may be inserted on a given scale in their position, similarly to Google Maps; what's more, for images taken by drones it allows them to be oriented according to the angle of flight and on their real scale in line with the width and height of the sensor and the focal distance. The data associated with the image may be consulted at any time.
Web Map Services
It is possible to capture and insert in their real position on the drawing the compatible WMS (Web Map Services) and WMTS (Web Map Tile Services) provided by any supplier (i.e. regional mapping institutes, cadaster and other public and private entities).
Operations with Images
Without leaving CAD it is possible to carry out on the images inserted in the drawing all kinds of basic transformations such as rotating, flipping, adjusting brightness, contrast, intensity, saturation, color balancing etc. The resolution, size and depth in color may also be changed. Other useful tools are: delimiting image as from a polyline, dividing an image into several images based on a sheet diagram and pasting images.
Images Deformation
By means of the use of reference lines or marks an image may be deformed by two methods: projective transformation or Rubber-Sheeting. The projective transformation will adjust four points at the most irrespective of the number of points used for calculation. The Rubber-Sheeting technique consists of a bilinear transformation of each of the cells of the grid generated from the pairs of points and whereby an adjustment will be obtained to all the points involved in the calculation.
The images obtained will be created, applying the nearest neighbor method, bilinear or bicubic interpolation or the Lagrange method. The calculation shows the mean squared error data, residues etc.
