<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif";color:black">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.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif";color:black">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.<o:p></o:p></span></p>
