How to stake out a right angle with GIS app Apglos Survey Wizard?
Help from the office
In Apglos Survey Wizard you can of course open files. So of course in the office they can make a file in DXF, TXT, CSV, SHP etc. that has a right angle in it. Many times staking out a right angle has to be done quickly in the field. Communicating back and forward is not the most effective solution then.
In some occasions there is a possibility that a right angle needs to be staked out. A right angle is a corner of 90 degrees. It can be modelised with three points or two lines and one point. So the basis of a right angle is a line.
Creating a line in the field
In the field you can export points and lines with Apglos Survey Wizard. This is easy in the survey screen. So we can create a line in the field without a problem. You go with the GPS kit to the point that is the start point of the line. There you tab on ‘Survey’. When there is a RTK fix a point will be exported from the field to Apglos Survey Wizard.
After that you go to the end point of the line. With the start point selected (having the orange cross on it) you tab on ‘Connect with’. Your line has been created.
Changing the line
It is possible that you want to change the length of the line. The line that has been created is orange. That means it is selected. We just go to the drafting screen. On this screen we select the option ‘Extend’. You can give the distance that the line has to be extended or shortened. Shortening is done with a negative distance. You can select from which point (begin point or end point) the line has to be shortened. After that you tab on ‘Draw’.
Knowing the length of the line
If you want to know the length of the line first then you go to the calculation screen. Here you select ‘Length’ and then you tab on the button ‘Calculate’. The length of the line will be given. After knowing the length you will know the distance that you want to extend or shorten the line.
Creating the third point of the right angle
Having done all this in Apglos Survey Wizard then we will make sure that we are in the drafting screen. There you select ‘Offset’. You also put a distance. And you select if you want to offset the line left or right. This last option is seen from being on the start point of the line.
When everything is filled in, then you tab on ‘Draw’. You will see a new line being drawn and having the start point en the end point being marked with a marker. Both newly created markers give a right angle from the line that was selected.
You have to go to the staking out screen. On this screen you can select the markers one by one. On the left side of the screen you will see the direction and the distance to the marker. Follow the direction of the arrow till the distance is 0 m. Then put on that location the picket or any other marker that you want to use in the field. You can do this for all the three points. After that you have succesfully staked out a right angle.
