some years ago I tried locating LAG2 when I frequented the Caliraya
area, but could not find it. My old GPS that time (Magelan GPS315, with
position error of about 14 meters) kept on pointing me to an area
several meters north of the junction where I could not find any possible
markers.<br>
<br>
Maybe my GPS was not accurate enough, or maybe the data I was using was converted wrongly (came from PRS92 and recalculated to wgs84), or the marker is gone, or the brass rod is indeed right at the junction of the two roads.<br>
<br>Anyway, here is the history of the coordinates ...<br>
<br>Below are the original values of the coordinates in PRS92. To convert it to WGS84, I first manually inputted them into GPS Utility which was set to Luzon Datum while I was keying-in the values (no PRS92 on GPS Utility back then). Then, I changed the datum on GPS Utility which automatically recalculated the values into WGS84.<br>
<br>This was based on what I have been told, that the difference between PRS92 and Luzon datum is very very minimal. Btw, the difference between Luzon and WGS84 is over a hundred meters.<br> <br>Perhaps Maning can do some recalculations based on the original PRS92?<br>
