One of the things that I manage is the flow of data between engineering projects and the field. Once the overall control points are established, there is not a lot of survey network information coming back in. Construction crew and RTK point data is delivered simply as a delimited ascii file. So what good does the Autodesk Civil 3D Survey Database do for me if all I have is raw coordinates?
Shared, controlled data. You can use it to share that point data with numerous team members, and manage it from one location. It’s like a low rent Data Reference…for points.
Let’s say you have a region that is going to get a lot of attention. You can master the site control gathered from existing survey(s), and everyone can pull their information from one true remote source. As new information is added, the database is updated accordingly.
Other benefits can be attained when numerous people are working on a large project with separate sites. The point data can be pulled down from the master database, and surfaces and location information can then be developed without concern that “You didn’t get the newest data”. When updates come through, the network gets flagged with an update, subsequently everyone receives the same update when things have been changed.
- Create a Database for an overall region, selecting an easy network path to point everyone to
- Create an associated network within the Database to add the data to. Separate site activity may go to separate networks
- Add data from sources such as Civil 3D drawings and ascii files
- Open my planning drawing, right click the Survey Points, and add points to the drawing.
That’s all there is to it. Everyone can access the data simultaneously.
As each dataset is imported, each session is logged as an Import Event, with various information including the source file path. One of the options available in the database is to re-import individual Import Events. This makes data adjustments easy to manage. The database automatically adjusts the related points, leaving you without concerns of damaging associated data.
This morning a technician complained that his data was way off target. A quick check showed that the data I was furnished was measured in meters. I adjusted the data, and had the database re-import the logged Import Event. Immediately following, the technician (and everyone else) was able to update his drawing with the new data.Continue Reading
