Surveying & Mapping
CAD to GIS Process
Future Discipline and Features
With the Departments’ recent creation of an enterprise Geographic
Information System (GIS) and increasing customer demand for geographic
information to aid in making critical management decisions, a cost
effective and efficient system for passing valuable computer assisted
drafting and design (CADD) data to our GIS environment is needed. With
that goal in mind the Texas A&M Transportation Institute (TTI) was
brought in to examine FDOT’s current systems, practices and processes to
develop a strategic implementation plan to manage this valuable data.
For more information please see the
TTI Final Report
Building on the TTI research we have identified and focused on several initial primary features to be passed to GIS, and have developed the workflows and processes required to accomplish this goal. We took advantage of our existing licensed products, and our current CADD delivery standards, to make this new GIS deliverable fit seamlessly into our production plans.
Create GIS features in either of our CADD environments per the FDOT CADD Manual. Export features and publish to GIS and create new layers for consumption by our GIS customers. Initial focus is on right of way lines, parcels and centerline (alignment). For more details, see the CAD/GIS Interoperability Presentation (PowerPoint, 10MB) and CADD-GIS Guidelines (PDF, 11.6MB)
Project Scope/Research and Testing: March 2013-February 2014
We anticipate the next features to be added to CADD and exported to GIS, will be Utility features. Also, we will be looking at this process in reverse, using GIS data to reference into the CADD environments.
