How many feet in a Square Acre of Land?

A question that I often receive from new land surveyors is  How many feet is a square acre?I am not quite sure why this stumps so many, but this is basically what I tell them with they ask.A square enclosing one acre is approximately 69.57 yards, or 208 feet 9 inches (63.61 metres) on a side. As a unit of measure, an acre has no prescribed shape; any area of 43,560 square feet is an acre.Keep in mind the following:Because an acre is a measure of area, not length, it is defined in square feet.…

Change of coordinates system from psad56 to wgs84

Problems in local government entities, about the change of Coordinate System from psad56 to wgs84Even 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…

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.

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…

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 looking…

Loose fitting plastic caps

The last two orders of caps I purchased for 5/8" rebar slide easily on and off the rebar. One order was from Stakemill and the other from Berntsen. Since both call for a model 5000 with either Permamark or PM I suspect both caps are permamark caps. We've tried rebar from three different suppliers with the same results.Has anyone else experienced loose-fitting plastic caps?

Instrument Seems to Lag location

We are having a problem with a robotic total station.It appears that the point stored is not actually where the prism is at but at a location whose position varies from the true location.  Sometimes the shot taken on the curb appears 0.5 feet into the roadway.  Other times the location appears behind the curb.  We have had this occur with two different robots, ( Focus30 and a Trimble S5).  We were using the same data collector so that is one area that may be where the problem exists. Has anyone…
