Make a Great Map of Your Engineering Building Traverse ©Mar Dr. B. C. Paul Note – This presentation contains screen shots from the Mine Sight and Excel Programs, both of which are created by software companies.

What Are We Going To Do Now that You Have Surveyed Around the Building Exchange notes with other teams –Each team only needs to go part way around the building – together you have a traverse all around the building An Excel Spreadsheet called Traverse Assistant was prepared for this class. You will put your survey data into it and get output suitable for use in – MineSight – a 3D graphics program that will create a visual map of your traverse

Take a Look at Traverse Assistant Traverse assistant Has you follow Several steps in Putting in your data You will enter your Data into yellow Fields Answers or Calculation areas Are in green or red. (Don’t mess with The formulas in these Fields)

Start by Putting in the Location of Your Instrument Station Put in the coordinates And elevation of your First point (the example has the State Plane Coordinates Of your first point by The grate near the Corner of Lincoln and Douglas) {Yes that mean you Will start by entering These very same Coordinates}

Next Enter Your Height of Instrument If you used a tape Measure in tenths of Feet you have your Instrument in decimal Feet – enter it here In this example I Assumed I had Measured my height Of instrument with a Regular tape in feet Inches and fractions of An inch I enter the feet I enter the inches I enter the fraction Of an inch – in this Case 3/16 – which The spreadsheet converted to decimals Note that I can only enter my distance in one type Of unit at a time – if I choose decimal feet it is not feet and inches. Your height of instrument is unique To your survey work.

Finally I Enter My Backsight Azimuth I happen to have my Backsight azimuth in Decimal degrees. (For backsighting the Power plant smoke- Stack the azimuth is degrees) Note I could have had That azimuth in Grads, Mills, or degrees Minutes and seconds. {This backsight azimuth will be the starting backsight Azimuth for everyone on this project}

I Scroll Down to Start Entering Information About My Foresight

I First Enter the Angle to the Right That I Turned from my Backsight In this case I Assumed I had Measured that Angle in Degrees, Minutes And Seconds But it could have Been in Grads or Mills. Note that the Spreadsheet Converts any of The measures to Decimal degrees.

Next You Will Enter the Vertical Angle to Your Foresight Different Instruments Measure vertical Angle differently. Some measure The angle from The horizontal – This is especially True of old Transits Many newer Instruments use A zenith angle Measured down From vertical Note that this spreadsheet Will take either a zenith or An angle from the horizon And will take it in grads, Degrees Minutes Seconds Or Mills.

You May Have Measured Your Distance to the Foresight by Stadia or EDM If you measured by Stadia just enter the Upper, middle, and Lower rod readings (all our rods are in Decimal feet)

If You Measured by EDM Skip Step #6 and move to #7 Enter your EDM Distance which Will already be In decimal feet Then enter the Height of your Reflector – note You can enter In decimal feet of Feet inches and Fractions of Inches depending On what kind of Tape you used. Note that if you have entered something for Stadia you should not also claim to have Done the shot by EDM

Scroll Down Again to Start Reading Your Answers We are going to run Minesight by starting at A known point and then Moving in a specified Direction at a given Direction. Thus we read the output For distance and direction In this example it is feet at an azimuth Of degrees.

Time to Fire Up Minesight!

Pick the Location You Will Have Your Project Files in

If it’s a new project location (most likely is) it will ask about creating a resource folder Say Yes.

Minesight Opens and It Asks for the Coordinate Range for Your Project

Lets Work on a Guess degrees N The Buidling is down in Here to the South and West North 381,288 East 2,570,639 Our survey stations won’t Go much further north And most will be to the south (ie – smaller northing) One of our stations is Over by the Arena a little Further east but most Points are to the west (ie – smaller easting)

More Guessing The building is probably less Than 1000 feet in each direction So our smallest northing is about 380,400 with a max of about 381,400 Our smallest easting is about 2,569,800 with a max of about 2,570,800

Set For Feet and Input My Coordinate Range Click Ok to Move on

I’m So Excited – Its Getting Ready to Go

I’m Going to Set Up a File to Keep My Drawing in Start by Clicking on Un-named to Highlight it.

I’m Going to Create a New Geometry Object

It Wants Me to Give the Object a Name I like Engineering Building on Surface (I could pick Anything) When I’m done Click Ok

Click on My New File to Highlight It I’m getting the File ready for Me to put Stuff in it.

Left Click On My Object to Pop Up A Menu Pick Edit

Note We Get An Open Pretty Yellow Box Ready for Our Stuff!

Turn on the Point Editor

Tell it You Will Create a Polyline

Enter the Coordinates of Your First Point and Click Apply You see the First pretty Dot appear

Next Enter the Distance and Direction to Your First Foresight I used the Distance and Direction from The Spreadsheet I can then click Preview or Apply

And Bully! My First Line Appears I’m now Ready to go Back to the Spreadsheet For my next point

I have two possibilities One possibility is that the foresight I just put in was a sideshot to a building corner –I might have taken several more side shots Another possibility is that I was foresighting the next point I would move my instrument to.

If I Am Doing Sideshots from One Point Obviously I won’t Be changing my Instrument Location Backsight Azimuth or Height of Instrument

I Will Change My Angle Right, My Vertical Angle and My Rod (or EDM) Readings

If I Am Moving My Instrument to the Foresight Point Here are the New coordinates Of the New instrument Station And here is the New backsight Azimuth (Copy them Down to use)
