Study Design Tool
Draw a study area, choose a simple transect design, and estimate survey distance and nominal mission duration. This prototype is intended for first-order study design rather than operational mission planning.
Study requirements
Use the polygon tool on the map to define one study area. Edit the polygon at any time; the design will update when you regenerate it.
Survey geometry
0° = north-south transects; 90° = east-west.
Mission assumptions
Angle from horizontal. Used with target depth to estimate the horizontal distance of one down-and-up dive cycle.
Survey estimate
Values below are geometric and first-order estimates. Currents, dive behavior, bathymetry, payload power, navigation, launch/recovery, and operational safety margins are not yet included.
Idealized dive cycle
Dive-cycle estimate
Orange dots on the map show estimated surfacing locations along the generated route. Depth and glide-angle changes update this preview immediately.
Calculation assumptions
- Transects are generated at the selected compass orientation and clipped to the study polygon.
- For the lawnmower option, transect segments are alternated and connected in sequence; connector distance is included.
- Nominal travel rate is speed in knots × 1.852 km/nmi × 24 h/day.
- Dive-cycle horizontal distance is approximated as 2 × target depth / tan(glide angle), assuming a symmetric straight-line descent and ascent.
- Map dots represent estimated surfacing locations, not subsurface profile positions or commanded waypoints.
- With multiple gliders, route distance is divided evenly among vehicles for the duration estimate only; tracks are not yet spatially assigned to individual gliders.
Waypoint files
Turn the generated survey into a mission file for a Slocum or a Seaglider, or load a waypoint file from either glider to see it on the map. A loaded file becomes the waypoint set, so it can also be converted from one glider's format to the other.
No waypoints yet. Generate a survey or import a file.

The mission over the seafloor
Draws the planned track as it would actually be flown, against real bathymetry for the study area. Dive depth can follow the seafloor instead of being fixed, which is what a pilot would really do over a shelf break or a canyon.
Bathymetry from the GMRT Synthesis (Ryan et al., Geochem. Geophys. Geosyst., 2009), fetched live for the drawn area. The 3D view follows Glider Playground (Orlando Prugel-Bennett, National Oceanography Centre, Apache 2.0).
