Virtual 3D modeling is a very important and hot topic for researchers of Geomatics. Many scientists are working in this direction. All over the world, so many educational institutes are available with its own campus. Campus is the land on which Institute; College or University buildings are situated. In the modern digital era, the demand of 3D Campus is increasing. Virtual 3D model of campus gives a good and photo-realistic appearance. In Geomatics market, So many image based techniques are available for 3D modeling. Photogrammetry and Laser scanning are the main Geomatics techniques. Satellite Photogrammetry and Aerial Photogrammetry is not easy to use by every person, because the images are not easily available for everybody. Due to this a new approach is possible to make virtual 3D Campus. Close Range Photogrammetry is very easy to use. Images are easy to obtain by any handheld digital camera. Cost and Time is main key issue for this. In this paper, we are giving a simple and cheapest solution to create virtual 3D campus of any educational institute by using simple photographs based on Close range Photogrammetry. In this study, we used simple digital images obtained by a Hand held digital camera. This paper will describe the introduction, methodology, advantages, drawbacks and limitations of this method. In this study, we used the study area, Campus of Department of Civil Engineering, Indian Institute of Technology, Roorkee, (Uttrakhand), India. From this study, we find out the height and length of building of Civil Engineering department. The result of this study is also within the permissible limit and acceptable. It is a significance study for 3D modeling by using Close Range Photogrammetry. This 3D campus model can be exported in various other formats for various applications. These 3D models can be exported to Google Earth also. These 3D campus models can also be published on the website of that Institute or University.
