<DIV>Good day</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>I am not very clued up on these aspects so any advise would be greatly
appreciated.</DIV>
<DIV> </DIV>
<DIV>Many thanks in advance,</DIV>
<DIV>Taryn</DIV>
