Who draws in millimetres? And why is that facility drawn in some arbitrary location with no spatial reference what so ever?
In the world of engineering drawings spatial reference is almost irrelevant, after all that’s the surveyors concern, they’ll tell them where needs to go. The engineering plan is there to explain the size and materials etc of a particular feature. So what can we do with that data? How can we integrate it with the data that is already in our spatially aware GIS? Well with a few simple steps we can easily bring this data into our maps and make use of it.
The Georeferencing Toolbar
If you’re often working with CAD data you’ll need to familiar yourself with this useful set of tools. This tool bar is made up of tools that simply allow us to position our data in the right place as well as precision tools for applying geographic coordinates to control points.
