I need some advice on choosing a GPS set-up to map estuarine habitats in the field.
Our SA estuaries are often very narrow (1 to 2 km wide) and habitats are small.
We distinguish between supra-tidal salt marsh, inter-tidal 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 1m², perhaps even better.
How should I proceed?
