USGS - Science for a Changing World

The U.S. Geological Survey (USGS) and the National Geospatial-Intelligence Agency (NGA) have collaborated in the development of a much improved global elevation model, the Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010).

GMTED2010 replaces the widely used, 15-year-old GTOPO30 terrain model as the best available global digital elevation model.

Useful for regional-, continental-, and global-scale applications, GMTED2010 is derived from numerous higher quality elevation data sources that were unavailable at the time GTOPO30 was developed.  The new sources include near-global Digital Terrain Elevation Data (DTED®) from the Shuttle Radar Topography Mission (SRTM); Canadian elevation data; SPOT 5 Reference 3D data; data from NASA’s Ice, Cloud, and land Elevation Satellite (ICESat); and updated Antarctica and Greenland terrain models.

More AutoCAD Civil 3D Surveying Help!

I get more questions about AutoCAD Civil 3D than I do on any other subject. The complexity of the program coupled with the myriad of settings required to make it a useful piece of surveying and design software results in it being very tricky to set up and use.

I’ve begun preparing training and educational videos, with my first video being “AutoCAD Civil 3D 2010 Video for Land Surveyors: Coordinate Systems” which I recently posted on YouTube and on this site. The post has a little written background, too, that you might find an interesting read. While videos and post allow for some in-depth exploration of any subject, I thought that a weekly feature with Surveying Quick Tips and Tricks about using AutoCAD Civil 3D would be useful, too. So here we go!

AutoCAD Civil 3D Surveying Quick Tips and Tricks

Last week I was working on updating a project drawing, using AutoCAD Civil 3D 2010, and I needed to move an image in my drawing. Simple enough, right? Well wait a minute, the image frames where turned off so there was nothing to select. What to do?

I knew how to turn back on the image frames in prior AutoCAD Civil 3D releases, but I’m still getting used to the new menus (or lack thereof-which may be next weeks tip), workspaces and, of course, the ribbon. I did find the image settings and turned the image frames on by:
