Transcript of Analysis of total station data
Analysis of total station data of IDL
By- ABINASH SWAIN, NIT Rourkela
Objectives• To simulate Total station data into computer using various softwares• To draw boundary of IDL • To show contour lines of various readings• To show bird’s eye view of the entire location• To find out 3D outlook of the location• Connecting observed points with google map

Softwares used1- Esurvey CAD ( By Esurvey Softtech(India) Pvt Ltd.)- Trial version2- Google Earth Plotter ( on Java Platform)
Esurvey CAD trial version• Input- Easting, Northing and Elevation (x,y,z) of various points by Total Station.• Output- 1-Plot of all points in 2D and 3D with options to series/short line joining. By joining points we can get the boundary of the entire survey.2- Contour lines of all points (by taking elevations)3- We have to add remarks (classes) of points. So that we can access particular class for any instance. There is option to add blocks and layers to various classes. Like drawings of hill for all hill points.4- 3D plotting option is not available in the trial version.5- Connecting with google map is possible by adding extension of Esurvey CAD with Auto CAD. Not possible with trial version.
To plot on google map with the readings from Total Station :
• We have to convert local co-ordinates to KML (keyhole markup language) • Then we can use these data to relate our readings exactly with google
map.• For this we need a software called goole earth plotter (Java based)
Google Earth Plotter• Converts local co-ordinates into google earth compatible KML co-
ordinates. • By conversion out field data can be imposed on google earth and vice-
versa. Even 3D view of blocks can be done in google map by using Esurvey CAD software.
