Generating Contours using Google Earth

Generating Contours using Google Earth

Without visiting site, you can generate contours for preliminary designs before actual survey done and even the actual survey can be planned with less expense. Though the accuracy level of contour may be low, it depends on the accuracy of 3D data in Google Earth. At many instances it has been observed the difference in height in Google earth and actual MSL varies between 3 to 1 meter. Sometimes it may be very high.

The benefit of this course is - preliminary planning of any infra projects like Roads, Railways, water ways like canal network, water supply projects, power transmission lines needs contours for designing.

Surveyors, Engineers and Architects can take this course and learn to use this great tool.

Lesson 1 explains about what is contour and how it is drawn in detailed manner..

Lesson 2 explains about Characteristics of contour , how contours represented in hill , valley , plain area and saddle .in detailed manner.

Lesson 3 explains about uses of contour and in which projects contours can be used in detailed manner..

Lesson 4 explains how to download Google earth and how to extract 3D data from Google earth, how to convert 3D data in to KML file in detailed manner. .

Lesson 5 explains how to convert 3D data in to contours and label it using QGIS in detailed manner.

Lesson 6 explains how manually contours can be drawn on Google earth.
