The Geospatial Value Chain: Stage Two

This post is the second in a five part series and will explain the five stages of the Autodesk geospatial value chain. The five-stage model may help you understand where you are today and how you can extend the value of your geospatial data going forward. This series is taken from the "Best Practices for Managing Geospatial Data" document.

Stage Two: AutoCAD Map 3D

At this stage, CAD files are still used as the primary data source, but AutoCAD Map 3D is used as the application for creating and editing geospatial data. AutoCAD Map 3D makes it easier for engineers, drafting technicians, and GIS specialists to collaborate on projects and to share mapping information. Project teams can use their AutoCAD knowledge and training while taking advantage of GIS tools and functions.

AutoCAD Map 3D provides specific functionality that is not available in AutoCAD:

➔ Multi-user access—Access DWG drawings at the same time.

➔ Work across tiles—Attach and query multiple DWG files, which makes it easier to work with tiled data sets.

➔ Coordinate systems—Bring in DWG, GIS, and raster data with different coordinate systems and havethe data overlay properly.

➔ Drawing cleanup—Detect and fix geometric errors in DWG files.

➔ Import/Export—Bring in data from other departments and vendors and combine it with data in yourDWG files (for example, ESRI SHP).

Many customers who have invested in AutoCAD Map 3D use only the basic features listed above and continue to maintain a large library of DWG maps. Data is stored as object data or as links to an attached database, such as Microsoft® Access.

When your organization wants to extend its CAD information to more people and to make use of additional mapping (GIS) capabilities, you may be ready to move to Stage 3.
