Time Travel
where& when
all geo data has a temporal dimension
temporal analysis
4D
...but it can be difficult to transport
options
- gpx
- expanded (shp, geojson, etc.)
w/ a bit of cleverness, we can balance simplicity with power
the problem
time travel is expensive
cheat time with data anchors
things that
stay constant throughout
timelines => checkpoints
interpolate the data in between recorded times
tools
- turf.lineSlice
- turf.lineLength
- turf.along
points =>grids
group data so you send less of it
tools
- turf.squareGrid
- turf.inside
- turf.extent
- JSONStream
