Digital Maps

JenniferSniffen — Thu, 10 Oct 2019 19:40:36 GMT

Is anyone out there accepting subdivision or condo maps digitally and then dropping them into ArcMap? We are interested in learning from you if you are. Ideally, we would like to accept maps in a digital format and then instead of re-tracing and re-creating all the line work we would like to be able to import the map into our Tax Map.

Jennifer Sniffen, when you say accepting subdivision maps digitally, what format are you referring to? CAD files (dwg, dgn)? PDFs?

If they are CAD, it really helps if they have a spatial reference (it might be a good idea to require that in submissions). That way you can place them into ArcMap (or Pro) in the right place). Otherwise, you might have to georeference it in.

Here are some resources on how to do that in ArcMap:

Thank you so much for replying, Adrian. Do you happen to know any organizations or municipalities that are currently doing this? I would ideally like to learn from someone else's experience.

Jennifer,

I would suggest reaching out to your local governments and seeing what process they take to do this sort of thing. That might be a good start.
