When detail is required in our very heterogeneous mangroves in order to track animal movement, the resolution afforded by a GPS is too inaccurate. Since Google Maps for the Buloh mangrove patch we are working in is tragically covered by clouds, detailed mapping is a critical step for this and future work. So its back to the Murphyian tape, compass and clipboard days for me, a tradition in our mangroves dating back tot he late-80's.
The student has to hold the compass though, not me. For she has to learn, make mistakes, get frustrated by inexplicable plots back in dry land and plan a remapping. I have to exercise restraint and remember that it was my mistakes as much as my successes that honed my skill.
