Traverse calculation excel sheet

I have done a link traverse adjustment using Bowditch in Excel but the results does not make any sense. I may be wrong. I have attached the file. Can you kindly help to check it out. I see that all the "bearings" are in the northwest quadrant except for the final leg, which is going to the northeast, if I am interpreting your data as you intend.

There seems to be a missing call or calls, or you were closing on a second point for which you had known coordinates. You definitely can't do this kind of adjustment without making it a closed loop or specifying a second set of given coordinates. The beginning coordinates are on the Constants sheet. Not sure why they aren't entered on the main worksheet.

It seems strange that the northing is for LP2 which is a station ID but the easting is for 'A' whatever that is. By the terminology I'm familiar with, those are azimuths, not bearings. Bearings are usually at least in older work given within a quadrant such as N 12 34 56 E. How did you get these values? If using a theodolite or total station you measure angles, and have to compute azimuths or bearings.

Those numbers might make more sense as angles left or angles right.

I find it strange that measured distances are computed by the scale factor from grid distances, which is opposite of normal. Which did you measure or were given or to start with? Note that the method is frequently employed subjectively and does not provide information for statistical analysis like the method of least squares.

Facebook Land Surveyors Spreadsheets.A Traverse consists of series of related points or stations, which when connected by angular and linear values form a framework.

The Purpose of a traverse surveys is to control subsequent detail, i. Fixing of specific points to which details can be relates. The accuracy of the control survey must be superior to that of the subsidiary survey. When a series of connected lines form a closed circuit, i. When the finishing point coincides with the starting point, then it is called as a closed traverse.

These closed traverse surveys have many applications like fixing the boundaries of ponds, forests etc. Present techniques used in traversing using total station as an open traverse. The steps are as described below. GPS pair points are fixed at a convenient distance, approximately about 3 to 5km. Care has to be taken that the pair of GPS points is fixed at a reliable distance at least 60m is advised for better results and on good monuments.

These points are fixed in such a way that they are clearly inter visible and should cater for placing the total station firmly on the GPS stations. Total station is to be checked for its calibration, prism constants for the prisms to be set in the instrument to avoid errors.

Total station is then used to conduct the traverse between the GPS points. This type of traverse ensures that the survey is started from a known pair of points and is closed on known pair of points. Care has to be taken that the last bearing is also taken for correcting the Adjustment. There are several methods to correct the traverse adjustments.

However, in most of the cases Bowditch rule is considered to bethe most reliable.

The other methods like transit method, Crandall method, Least Square Methods are used very rarely. The most accurate method which is known as a adjustment correction by the least square method is used when the accuracy required is very high.

This method finds itself applicable in the projects like tunnel works and works warranting for a higher the accuracy.

Open Traverses means that the starting and closing station is fixed with known Co-ordinates.With Google Sheets, you can create, edit, and collaborate wherever you are.

I wrote this program for my geologic field methods class. A traverse is a simple way to plot points of interest on a 2D map. When in the field, you may not have, or want to carry, appropriate surveying equipment or may not need that level of accuracy, so you can pace from point to point measuring the compass bearing and counting number of paces.

You must close the traverse by returning to the original starting station or point. You will need to have your conversion factor calculated to feet per pace. One way of doing this is measuring out a known distance, say feet, and count the number of paces. Then take feet divided by your count. A pace is two steps. Start with your left and count every time your right foot makes contact with the ground. Also, bearings must be in azimuth 0 to degrees. Refer to any geologic field book for more information.

Make sure you start with a blank excel file. It is easiest to use if you have your notes setup in the same order as the input boxes arise. Below is a summary:. Here is how to use it for those less inclined to code.

If you set up your notes is this manner, you just need to read across from left to right, ignoring the occupied station after the first entry. It will automatically copy down. You will see X and Y components of the vector calculated which necessary for error vector calculation, but will be removed later. Now you have a closure error of zero.

The most important thing is the percent error.

If your error is high, you may want to go traverse your points again and check your bearings. Also, check that your forward bearing minus your reverse bearing is approximately plus or minus degrees. Below is an example of the final product from the data given above. This is a very simple macro and still needs much work, especially in error handling and handling user input error.
