Hi,
Busy developers, would you believe that some linear referencing features could
be handled even theoretically by OpenJUMP? Something like
- Make a buffer for a linesting, so that a section of line between x and y
meters from the selected vertex forward/backward would be selected and buffered
with z meters. Use cases: Select shops which are conveniently close to a
planned route. Select the downstream fields which will be contaminated within
one hour after a shipwreck and oil leakage.
- Show distance to a vertex along a line.
- Tie attributes to linear features without splitting line into pieces. Use
cases: Speed limits, starting from the beginning of a linestring are from 0 to
2340 meters 50 km/h, from 2340 to 9850 m 80 km/h etc. Bus stops locations are
1.12 km, 2.30 km, 3.50, 6.70 km from the beginning of bus route number 6 in
forward direction and something else in reverse direction.
