merge two different SDF files

464 Views, 3 Replies

I have two SDF fileswith simpley polygon, lets say parcels boundary

in the A.sdf, each feature has 10 feature data properties, i.e. taxid, owner, zone, value etc

in the B.sdf, each feature has 3 feature data properties i.e. area, layer, colour

 

I would like to move all the features from B.sdf to A.sdf, however

at the least I need to ensure that features moved from B.sdf now has the same  number (10)of feature data properties as in A.SDF

 

Only solution I could come up with is to

import A.sdf file into Map3D so that I have a datatable.

erase all the features,

then B.sdf file and use the attach data to attach the table data to each feature

then output to A.sdf using append.

 

there must be a better method, any suggestion

If they both have a common ID, you can connect to both, then join the two.  You can then either work with them in a joined state or export to a new file with all 13 fields.

Clarify - are the polygons from the the same source with different data - i.e one on top of the other  or are the polygons seperated in space

 

sdf b does or does not have the ten other OD? or just the three?

 

if set b aligns on top of set a an intersection will give the result in the intersection output

 

if the sets don't align _mapimport  both sets with the data and _mapexport with all the data to one new sdf

I tried the bulk copy, and did not get the desired results.

for one, although A.SDF has all the feature data from B.sdf it has not merged into the resident Schema.

 

A.sdf , schema "Parcels_North" over a dozen feature properties

B.sdf schema "Parcels" about three feature properties

 

after the bulk copy in A.SDF I have both Schemas

ultimately I woul like just one "Parcels_North"

 

as an FYI A.sdf is from the county and B.sdf is created by Civil 3D
