Kevin D. Allen replied to ERIC TENOR's discussion Deformation monitoring
"First of all, you would be most likely working with a geologist so they would determine the locations to be monitored.  The survey team would set the permanent monuments in these locations, allow for these to settle and become stable ( 3…"

Kevin D. Allen replied to Mark Sarver's discussion TSC2 Battery Life
"Try taking it to an Interstate Battery store.  They can check it and possibly re-build it.  If they can't, look up Coastal Instrument & Supply in Florida - 800-562-8626.  They specialize in rebuilding survey instrument…"

"Quick answer.... no...            long answer,yes   you still get the proper corrections for the base as it handles the GPS signals, you will not benefit from the additional GLONASS of Galileo signals as your…"

"The previous commenets are as mine - got to "Surface Properties"  then "Edit Surfce Style"  then pick the Display tab and make triabgles visible.  You will see some triangles cross your channel sideways - go back…"

Kevin D. Allen replied to Mohamad Ezat's discussion Scale Factor in Tower
"Mohamad, A bit more information would be useful - 1) when you say a scale factor was used on the control points, are you referring to the general site survey?  2) When you say 95% do you mean that the piling and shoring work is 95%…"

Kevin D. Allen replied to Mitchell Grimm's discussion Compass Traverse Calculations
"First of all you have got to understand the accuracy limits of your equipment.  A good hand compass - one that can read to a degree or two - is hard to use to start with.  It must be held very steady, it must be level for each reading, it…"

Kevin D. Allen replied to Soumen Samanta's discussion In Traverse Calculation which Rule is used mostly? Bowditch Rule or Transit Rule?
"The transit rule was more or less the standard here in the US until PC's came into use and Least Squares was developed.  Even today with smaller traverses transit is superior to Least Squares. Good Luck Kevin"

Kevin D. Allen replied to Chris Wasemann's discussion Traverse between two known points?
"CW, So you know the coords of the two points you are traversing between right? You can calc your known bearing between these two points.  Just set up on a random point between them, backsight the first and then traverse however you need to get…"

"Oooohh Myyyy - the young ones today are sooo spoiled!!! You comment "The big complaint with local base is having to setup a base and break it down."  is hilarious!!  Can you imagine these same crews had to carry a 20 pound gun…"

Kevin D. Allen replied to DANIEL MCCARTHY's discussion inconsistent RTK elevations
"AHHH Daniel.... You and so many others ask the same thing from time to time.   There are several components to your answer starting with the fact that GPS in inherently less accurate vertically than horizontally.  "But…"

Kevin D. Allen replied to Doug Cruse's discussion Unspecified Projection Error ~ TDS Software
"Doug, You most likely need to update the Geoid file that is in your data collector.   Try doing an initialization setup for the sessions by using the "here" option to find a local coordinate  Also, if you are close to a zone…"

Kevin D. Allen replied to Randy 's discussion HIPER PLUS
