Point data in Arcmap Report this article as Inappropriate to us !!!Login to Reply

I have imported point data from Autocad into Arcmap. Each point represents a structure on an archaeological survey. Now I need to attach elevation data to each point. Eventually I want to display my data in 3D and use 3d analyst to compute veiwsheds. How do I go about doing this?

Does the elevation data exist in the AutoCAD file?

If not, what format is it in, or what source of elevation data is available?

Hi,
You need to have a field in the database that represents your elevation (z-value). You can either create a new field called elevation and enter the data in using ArcMap, or if the data exists in another database somewhere, you can join the two tables.

Then when you use 3D Analyst you tell it to use the elevation field you created or joined.

If the elevations were in the original CAD file, they will be brought over during the import and shown as a field in the tables/database.

Good luck.
