May 4, 2015 evening

|

Currently 72 degrees in Delmar with today’s heat breaking. Today reached 87 for the first time since early August 2014. If today was in 2014, it would have been the second or third hottest day of the year. Not too oppressive as the humidity is low but still toasty. Prime wildfire weather in the mountains.

Tonight will drop to 59 degrees by daybreak and the warm spell will continue into tomorrow with temperature expected to reach 77 degrees tommorow. I much prefer this heat to the frigid winter that only ended a few weeks ago.

Good night. Sleep well and be safe with fire.

Northing-Easting

Do you think Northing-Easting / UTM will eventually replace latitude and longitude for coordinates on all printed topographic maps?

One could argue that Northing-Easting is harder to write down, hard to remember, and you have to make sure you set the proper the proper zone in your GPS before using.

On the other hand, latitude and longitude usually aren’t square on maps, because of projection issues. You can’t project latitude and longitude for maps (WGS 84) without significant distortions.

Google Maps uses Northing-Easting internally, but uses latitude and longitude for their user interfaces, including scripting. It works, but is a lot of internal conversions to make it work.
