Lat Long lines

Years ago I was on a SAR team in Pinal County, AZ. We worked in Lat/Long so I used to put the Lat/Long lines on my map so it was divided into Minute squares. Since we worked in degrees.minutes.minutes. I could then easily look at a map and pinpoint where in the square a lat/long location would be. In minute.minutes, as you know the designation is in tenths. So, when given a reading, for example of 38.52.750 and 104.59.500, I knew the location was 3/4 up the square and 1/2 way across the square within seconds. I even made my own lat/long divider, similar to a UTM divider I could readily drop in the square to get a more accurate location. If you are going to make maps especially for SAR groups, then you should block the map in the units they use, lat/long, UTM, etc to make it easier to find the location literally in seconds.

    Hi Patrick,

    Are you asking about adding gridlines? You can add UTM gridlines to the map viewer on the web using the Config menu> Show UTM/USNG web. You can do the same thing on the mobile app by going to the 3 bar menu (upper left hand corner)> Display Options> Shoe UTM/USNG Grid. If you are generating a PDF, you can add either UTM or Lat/Long (in degrees or degrees minutes) to your PDF using the Print Options menu.

    Best,
    Meghan

    I mean you should add the grid lines on the paper map. The viewer on the web is not always available in the field. There were plenty of places where the teams in the field could not get signals, so the paper map is all you have available. With grid lines on a paper map it is so much easier to find a lat long or Utm location.  I don’t know what grid system is used in California SAR, but whatever it is put those grid lines on the map.  Ask those who actually use the paper maps if this would be helpful, not the people who give you input but don’t actually use the map. 

    Just a suggestion from someone who used maps in the field and understood the fractions of a lat long location give in degrees. Minutes.minutes. Works the same for UTM. I could put my finger on a location in literally seconds.

    I'm not sure if you saw this in my previous response but you can add gridlines to a printed paper map. When you generate a PDF (which you can then print), you have the option to add UTM or Lat/Long (in degrees or degrees minutes) to your PDF using the Print Options menu (please see attached screenshot).

    As someone who also personally uses paper maps in the field, I can appreciate the importance. Hope that helps!

    Thank you,
    Meghan

    I take responsibility here for not explaining myself properly. I understand that I can print a map with the grid lines, but I am talking about the water proof, laminated maps that you print. 
    Thank you

    The same option is available for the maps printed by Mountyn.co. In the print interface on the left side in the same place as generating PDFs are options for Lat/Long and UTM.
