Reach RS and XYZ coordinate question2rs+

[michielluijken (M Luy)]

Hello Emlid community,
I am completely new to gps (and no survey background) and just discovered this forum
I have just ordered an Emlid Reach RS+ Base and Rover and it on its way
I am pretty excited and realise there is quite a bit of study to do, but I am confident I could manage.
I want to start using it for stockpile (volume) measurements and bathymetric survey
I only want to use it a local grid and set my base point origin at 0,0,0

I am worried that I might have over looked the fact that export is only in lat, long
And that converting co-ordinates to a x,y,z grid in meters is not that simple

I found a thread with exactly the same issue but unfortunately its closed (is it not better to just keep open?)
But I did not really find a simple solution, this is the link to the thread:

Reach RS and XYZ coordinate question

I’m a new Reach RS user, new to GPS measurement, and am really happy with my experience so far. Our application is to use the Reach RS equipment (one rover, one base station) to measure ground control points for use in our aerial drone mapping. We use Pix4d to process the GCPs and drone imagery and I am comfortable and confident in that workflow. The Survey capability of the Reachview app allows for three file export types and the ESRI_Shapefile is the best for my Pix4d application. The DXF …

Can somebody point me in the right direction? or give some other solutions (i.e. budget is gone after this purchase) Accuracy is not that critical but should be less than 30cm, so I need a correction on a standard GPS

Thanks!

You can use qgis to calculate volum and it support import of GeoJSON, CSV etc directly from Reachview. Qgis is also free.

Lat/long can also be converted to UTM grid which is also XYZ in meters.

Hi @michielluijken,

As @TB_RTK mentioned, you can do geoprocessing in different GIS. QGIS is just the most popular one.
We’ve such instruments on our to-do list but at the moment you can do that kind of measurements only by using 3rd-party software.

Thanks Andrew
Do you maybe know what of accuracy I get when I convert lat longs to UTM with for example QGIS?
I can imagine there will be some minor deviations?,
Thanks

Hi @michielluijken,

If you choose the right UTM zone, there’ll be no deviations.

Andrew.
