Survey point shifter

Correct your survey points after the base position changes. Enter a north, east and up offset, or calculate it from the original and corrected base positions. Files stay on your device.

Positive values move points north, east or up; negative values move them south, west or down. Enter at least one value; blank fields count as zero.

What it accepts

Use RoboDot shot files or a CSV with one named column each for latitude, longitude and height. Coordinates must be decimal degrees and heights must be metres. Tab- and semicolon-separated files are also supported.

Use the original shot file if your export includes derived elevations. If a point row is refused, the page names the line and the reason, and nothing in that file is shifted.

Before and after: +0.500 m up

A 0.500 metre up correction changes height from 150.0000 to 150.5000 metres and ground elevation from 147.9150 to 148.4150 metres. Latitude and longitude stay the same in this example.

When you'd use it

Use it when a base survey or control tie improves the position used for your shots. The tool applies the same north, east and up correction to each point. Other coordinate columns, such as easting and northing, are not recalculated.
