[OSGeo Africa] Field mapping GPS suggestions please

[Wilhelm Herbst]

Hi Taryn

Whoever told you that the GPS in a phone is as good as Trimble know nothing about GPS.
A Phone will typically give you 30 to 50 meters accuracy.

We provide a solution for doing what you want, using either android or Trimble.  Let me know if you need more info

Good day

Is anyone able to give me some advice please on choosing a GPS setup to map estuarine habitats in the field?  Our SA estuaries are often very narrow (1 to 2 km wide) and habitats small.  We distinguish between supratidal salt marsh, intertidal salt marsh, reeds and sedges, among other habitats.  Reeds and sedges often form a very narrow band along an estuary.  Accuracy needs to be as close as possible to 1 m2, perhaps even better.

Someone suggested using a windows / android phone running ArcGIS Collector as the GPS in them is as good as a Trimble and also cheaper?  It could also be a separate GPS linked to a tablet, not necessarily a single hand help GPS unit with mapping options.  We use ArcGIS software for final map productions and analysis.

I am not very clued up on these aspects so any advise would be greatly appreciated.

Many thanks in advance,
Taryn
