Surveyors dominantly perform their work assuming the Earth is flat. The purpose of the State Plane Coordinate System is to allow working as if the Earth is flat when doing surveys of sufficient extent that it is no longer a good idea to make that assumption.
Three years ago, mobile LiDAR was just beginning to emerge as a potential mapping and surveying tool. A few forward-thinking firms took a chance--with a rather hefty technology investment--and began blazing new trails in railway, infrastructure and asset data collection. Today, those investments are paying off through an increasing number of mobile mapping contracts.
The UAS technology offers greater reach beyond conventional surveying and mapping techniques due to its portability and flexibility and relatively fewer physical restrictions than conventional photogrammetry.
For weeks now, news reports have been showing the Mississippi flooded, dams intentionally breached by the USACE, and farms and towns completely flooded out. Do our news networks not understand that that it is our failed infrastructure that cannot convey and manage the cresting water levels?
“Geodesy” and “geodetic” are terms many plane surveyors love to ignore. However, knowingly ignoring these concepts is different from denying that geodesy is a valid science that must be understood enough to know when and why it matters.
I think a process should be developed where the survey license is augmented by an educated and skilled level of survey personnel who will specialize in model building. The surveying community is a natural choice for this since it is simply digital stakeout.
Although companies have been developing 3D data for years (through the 3D Buildings layer in Google Earth and other tools), few have taken it to a street-level realm in building highly accurate 3D models for use within existing widespread CAD/GIS platforms. However, those that have taken this approach are finding a successful new business model.
Under the GSA’s National 3D-4D-BIM Program, established in 2003, the Minton-Capehart building was identified with a number of other federal buildings as a possible target for building information modeling (BIM) along with additional energy retrofits. In early 2008, GSA awarded a $35 million contract for a phased renovation of the building to Cincinnati-based Messer Construction Co., which contracted Berding G.J. Berding Surveying Inc., based in Milford, Ohio, to handle the scanning work.
