The Location GR Field Is the Whole Point
Grid references as a location type — not a text field, but a GPS-pinned coordinate captured at the moment of observation. When a supervisor visits Group 4 at 1035 and logs their position, that pin is not approximate. It's the actual location on the map, captured at that specific time, associated with that specific group and staff member.
Most trip supervisors running multi-group outdoor expeditions rely on radio check-ins and hand-drawn maps. The problem with radio check-ins is that they're verbal — the information exists for about four minutes and then it's gone. The problem with hand-drawn maps is that they don't timestamp the observation. When you're writing an incident report for a near-miss on a river crossing and you need to reconstruct the last-known location of each group at each time of day, the verbal radio check-in record is useless and the hand-drawn map is imprecise.
A log entry with a GPS pin, a timestamp, a group number, and a staff identifier is a legal document. It tells exactly who was where, when, and who observed them.
Multi-Group Field Management in Real Time
Eleven group slots. Up to eleven independent sub-groups, each with their own staff lead, each being visited and logged by a supervising coordinator who moves between them across the day. The entry rhythm is: arrive at Group 2, log time-in, log location GR, note the activity and what the group is doing, log student observations, record communication method if there was a handoff, log time-left.
The Type of Communication field matters more than it appears. In Person means the supervisor was physically present with the group. Mobile means they received a check-in by phone. Voice Mail means a message was left — communication was attempted but not confirmed two-way. Email is asynchronous. Other covers radio, satellite communicator, or any field communication method outside the standard set.
At the end of a six-group expedition day, the log shows you exactly which groups received direct in-person visits, which were checked by mobile, and which were in voice-mail-only contact windows. If an incident occurred during a period when a group was on mobile-only contact, the communication type field documents the supervision pattern for the review that will follow.
Student Notes as the Assessment Record
The Student Notes field is the performance observation layer. An outdoor education trip isn't just a logistics event — it's an assessed experience. The notes logged at each group visit capture which students are struggling with navigation, which are demonstrating leadership, which are having a rough day that the evening debrief needs to address.
When six staff members each log group visits across a three-day expedition, the aggregate student notes become the raw material for the individual student report. Filtering on Group 3 across all entries shows every observation logged against that group — by any staff member, at any time — in chronological order. That's the expedition record for Group 3, ready for report collation.
The Activity Notes field separates the group's general activity from the individual student observation. Group 4 was conducting a navigation exercise in the upper valley at 1140 — that's Activity Notes. One specific student was leading the group on bearings and making good decisions — that's Student Notes. Keeping those layers separate makes the report collation cleaner.
The Time Left field — a full datetime, not just a time field — records when the supervisor departed that group's location. The gap between Time (arrival) and Time Left is the duration of the visit. A visit where Time Left is missing or equals Time means the entry was created but the supervisor didn't log departure — which flags an incomplete entry when the records are reviewed post-expedition.
