... it seems reasonable to me that we should think about a final set of editing tools, also concerning runways and taxiways:
- curvature tool: select either two points and smoothen the turn between them, either linearly on exponentially
- straighten tool: select either two points ans straighten the roand between them
- elevation tool: select either two points and either make the road following the terrain or straighten it (in terms of elevation only)
- closing tool: select the endpoints of a road (distance between them TBD) and close the road
- cutting tool: selection any two consecutive points of a road and break the road between them
- connecting tool: select the endpoints of two different roads (distance between TBD) and connect them (should be preferably possible even between roads of a different nature e.g. asphalt and dirt road)
- intersecting tool: selecte the endpoint of one road and any point of a second road and connect them (minimum angle TBD), forming fillets of a defined radius, thus adjusting to the elevation and the slant of the intersected road (should be preferably possible even between roads of a different nature e.g. asphalt and dirt road)
None of the altered points should be labelled in any way but remain freely alterable within any of the tool's capabilities thereafter
