1,000 missing survey data points to be fixed by interpolation
Feb 11, 2012 2:32 AM
not sure, if this is the right forum, (just a new comer)
I have large data of around 10,000 drainage pipe segments and 10,000 junctions in ArcGIS layer
The problem is: due to some reason certain junctions could not be accessed for survey, thus 1,000 entries are missing for pipes and junctions' invert elevation
Logically, interpolation should work here. (based on slope, u/s tag invert level or two junction u/s tag invert level or likewise)
Tried to do it manually in excel, but quite tiring and with less confidence (unprofessional too)
Any clue how to fix it?
Can send the shp files if required
Thanks in advance,
