[OSGeo Africa] Field mapping GPS suggestions please

[Taryn Riddin]

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
