Change of coordinates system from psad56 to wgs84

Problems in local government entities, about the change of Coordinate System from psad56 to wgs84 Even though there are many professionals with knowledge of cartography and geodesy, in the local government entities in Peru it is still difficult for those who work within these, to generate a reference or map in which it is reflected, the real change or conversion of the psad56 coordinate system to the wgs84 system without this causing numerical location problems. It seems that there is no…

Hi, Does anyone have experience with RTKlib PPP-kinematic processing? I would love to discuss and learn more about it. I would be interested in surveying tree locations on a very remote block of land with no nearby CORS. It doesn't have to be kinematic, but I still want to learn about this method anyway. Kind regards, James

Electrical liner

Safety while dealing with electricity or electrical appliances is a must. While dealing with electrical liner and what kind of electrical liner is best, it is better to be updated. Leaks in geomembrane can be very difficult to handle. Through electrical liner, one will be able to identify those leaks and then do what ever is necessary. Surveying from time to time and then taking steps can be very helpful.

Promark3 and WNRO

Hi, Our group has been taking DiffGPS readings with Ashteck Promark3 DiffGPS equipment for about 9 years with very few problems. However, shortly after April 6 2019 - the date of the Week Number Roll Over - the data our units collected would no longer  process in the GNSS software.  I could load the rover data files and they would load but if I included the base station data the program would choke during the file loading stage.  I could also load the base station data and correct it using the…

Grading Permit Plans in Pennsylvania: Can a surveyor calculate and sign off on Infiltration Beds and trenches?

I am a licensed surveyor in Pennsylvania and work for a full service Civil Engineering Company.  I have been getting a lot of requests for grading permit plans.  More and more townships are requiring Infiltration beds for roof drainage discharge.  Also, Infiltration trenches along driveways.  The calculations are pretty straight forward.  Can a PA licensed land surveyor sign off on a house permit plan containing these drainage features?  I have always had an in house licensed engineer perform…

BEING THE BEST

Lately I have become intrigued by the word "Best". When I was beginning in my surveying career, I told my father that I wanted to be the best surveyor there was. His response was: "Remember, David, being best is a matter of opinion, either yours or someone else's, and neither matters." Now, after 54 years of being in the profession, I have realized the wisdom of his response to me. If you think you are the best, you are looking "down" on others. If others think you are the best, they are…

Contract Work Heavy Overtime

When I first started Land Surveying I would get offers to work on these massive jobs that offered outrageous overtime. I can't seem to find them anymore. I'm an extremely well rounded crew chief that knows the office and field from boundary surveys to laser scanning and construction layout. I'm at a really good company right now, but I'm looking for a year or two of crazy paychecks to get my wife's business off the ground. Does anyone know who's doing things like this right now?

Automatic Topographic Mapping?

Good afternoon everyone I work for a transportation company. I would like to create grade diagrams (eg side-view tophographic maps) for certain sections of our network. Is there any way of automating this process? As you can see on the attached example, I require route distance to be indicated on the X axis with grades (ie gradients) on the Y-axis.  Ideally, I would simply switch on a GPS/elevation system that would automatically plot this information as I moved along the route. Any and all…
