Intersecting GIS Parcel Data with an alignment ROW

257 Views, 6 Replies

Hello,

 

I am a beginner with AutoCad software, and I am currently using Civil 3D/Map 3D 2009.

 

I imported a shp. file containing property information (owner, area, address, etc), and also imported an alignment row as a sdf. file. The row is a closed polygon.

 

My goal is to intersect these two types of data so that I end up with information on the number of properties effected by the row.

 

Is civil 3d 2009 capable of doing this? If so, how? I found a youtube video on using the 'Offset Alignment' command with Civil 3D 2010, however, is not the same for 2009. 

 

Any help would be appreciated, Thanks.

With Map3D you need to use data connect and bring the parcel shp file and ROW sdf file in as FDO features, then use the intersection option on doing a overlay analysis. As for the ROW offset you need to ask in the Civil3D forum.

I like Murph's overlay suggestion - if you save the result as a shapefile, you can open the .dbf in Excel or Open Office and pull any stats or do math there.

intersection does give 100% right answer.  exceptions are where the ROW crosses multiple sections of one property i.e  L S U Z shaped parcels, rivers & roads with S curves, which create two or more new polygons in the intersect file.  This inflates the number of affected parcels from the original parcel layer. 

 

intersect sdf  file;  data table and select all, copy and paste to excel for data analysis.   is that acceptable for this case?

 

Thanks

I meant does not give 100 % right answer. :smileymad:

It's a bit of a hassle, but you could take the original file and the overlay result, join the two using the feature ID as the key in a one to many join - that will get all the data in one place, but you'll still need to massage it (possibly) in Excel.

roundabout

 

intersect   source ROW    Overlay Parcel   result is Row_intersect

 

Theme the Row_intersectSDF using the FeatId2 as individual values. the number of rules = the number of parcels the ROW crosses.
