MODERN DATA COLLECTION-PLOT YOUR DISTOMETER MEASUREMENTS WHILE MEASURING IN AUTOCAD

MODERN DATA COLLECTION-PLOT YOUR DISTOMETER MEASUREMENTS WHILE MEASURING IN AUTOCAD

Plotting while measuring saves time and make the drawing accurate with no ambiguities. Creating accurate drawings is painless with a Bluetooth enabled DISTO device. If you paired the Distometer with AutoCAD mobile app, the Plotting can be done simultaneously.

First turn on Bluetooth in both devices and pair them. See the image below.

 



After tapping on “Connect to Leica DISTO”, make sure your Leica DISTO device is turned on, and that the Bluetooth of your mobile device or IPAD is also turned on.

The laser icon on the top bar will be displayed in green to indicate a successful connection.

Simply create a line in your drawing, take a measurement with a DISTO, and the length will update automatically. It’s the quickest way to cut your drafting time in half.

Once the device is connected successfully, Read More

MUST HAVE GPS APP FOR LAND SURVEYOR (OVER 10 MILLION DOWNLOADS)

‘GPS TEST’ A MUST HAVE GPS APP FOR SURVEYOR (OVER 10 MILLION DOWNLOADS)

There are so many GPS apps can be found in the app stores with lot of recommendations and advertisements. But ‘GPS TEST’ simply outperforms them with its simplicity and in-depth information. Over 10 million downloads with excellent ratings and actual user reviews make this app a shining star.


 

Land surveyors mostly deal with UTM coordinates.
Unlike other GPS apps, ‘GPS TEST’  gives you the UTM coordinates. So that the accuracy of survey works can be checked roughly in few meters. Just got settings and select UTM in the format and WGS84  or the required datum. It will display UTM coordinates with zone and altitude as well. Read More

Is it possible to Survey without vertically holding the GPS Pole?

Is it possible to Survey without vertically holding the GPS Pole?

Is this Land Surveyor doing right?





In common sense no one will accept the surveyed data in above manner. But time has changed. Nowadays you can survey in any angle without holding the pole vertically.

The Leica GS18 T is the world’s first tilt compensating rover, so that you can survey without holding the rover vertically. As above image depicts you can measure even under a vehicle truck. You will save a lot if time because it is  no longer needed to hold the pole vertical to level the bubble. Read More

Basic methods of GNSS/GPS setup or measurement

 

As we know a typical GPS setup needs a base and rover. The Base is setup in the known control point and the rover used for the surveys. Leica GS 15 GPS is taken as example in this post. It can be set up in 3 different methods for the GPS Surveying. They are

  1. Setting up with internal antenna
  2. Setting up with external Radio or antenna
  3. Setting up with GSM modem

It will be described briefly how above mentioned system works.

1.Setting up with internal antenna

In this method the small “L” shaped antenna is fixed in the base and rover. The following photos shows typical internal antenna. The range of coverage  is around 2 km. This method is simple and fast but less coverage. Read More

How to Calculate Scale Factor (in Land Surveying)

How to Calculate Scale Factor (in Land Surveying)

scale factor

A map projection provides a means of representing the curved surface of the earth on a plane surface so that coordinate grids can be defined and maps drawn. The relative positions of points on the grid are altered slightly from their ground positions as a result of using Transverse Mercator Projection to account for the curvature of the earth. The formula for the scale factor is

Scale Factor=Grid Distance/Measured Distance (at MSL)


For example take these two coordinates Read More

How to divide a curve or arc in to equal segments in Autocad – tutorial (divide tool)

How to divide a curve or arc in to equal segments in Autocad 2016 – tutorial (divide tool)

  • The “measure” tool will divide the arc in to specified length point, so there can be an odd value at the last segment. For example if the arc length is 45 m and specified length is 10 m, only the last segment will be 5m instead of 10 m.



  • The “divide” tool will divide the arc in to specified number of segment of equal length of points, so there won’t be any odd value at the last. For example if the arc length is 45 m and specified number of segment is 10, each segment will be (45/10) 4.5m interval.

How to divide a curve or arc in to specified segments in  Autocad tutorial

How can you divide a curve or object into equally sized segments?You would have tried to find a solution for days! It doesn’t actually have to be a ‘physical’ devision. But it would be good to know a solution for both: dividing eg. a curve into equally sized segments, ie. creating vertices Read More

Temporary Adjustments of Total station

Temporary Adjustments of Total station

Adjustments which required to be made at every instrument station before making any observation. It can be done through following three procedures,

1.Centering the Total station over the station.
2.Levelling the Total station.
3.Elimination of parallax.

 

1.Centering the Total station over the station.

 

centering total stationlaser plummet

This include the Centering of the Total station over the ground mark and also approximate levelling with the help of Tripod legs. While centering, it is necessary to ensure the approximate levelness; otherwise the centering will be disturbed when subsequent Levelling of the instrument is done. It can be done either using a plum-bob or laser plummet.

2. Levelling the Total station

Accurate Levelling is done with the help of plate levels using levelling screws.Here the Vertical axis (plumb line)of the Total station is made truly vertical.
