The topographical variations in the surface of the earth and the tilt of the camera affect the distance with which features on the aerial image are displayed. The more topographically diverse the landscape, the more distortion inherent in the photograph. As a result, real world distances are not represented uniformly on the photograph. For example, an inch measured in a steep area would relate to a much longer distance than an inch measured over a flat surface such as a plain.

A map that displays only the x,y locations of features and represents only horizontal distances.

Planimetric Mapping is committed to use the advanced technologys and softwares to better advance our products and service to our clients. Our team of trained photogrammetrists, graphic QC/editing professionals has the education, technical background and experience to create a highly accurate, consistent and well organized photogrammetric product.

In order to map from a Stereo pair of Photograph some pattern of control points should be available. These could be obtained by Ground methods alone. If the job is bulky in nature the amount of control will also increase proportionally which will result in 

• Higher cost
• Increase in time
• Unwarranted delays in map making

For photogrammetric compilation the control points should be at ideal locations. These requirements cannot be met by using Ground methods, due to various constraints in fieldwork. Thus the possibility of dignifying the network of controls based on a skeleton framework of ground controls using aerial photographs was evolved and the method is widely known as aerial triangulation.
