Grid Lines
« on: August 18, 2005, 05:55:46 PM »
Hello,

    This might be a silly question but I would really like to be able to print out maps with Lat./Long lines. Is this possible??

TIA
Steve

I'm not sure if there's a setting for that, but you could always make your own custom lines, like I did making a custom GPX file using notepad:

after some research, it seems like Grid Lines are usually done in the UTM system, not Lat/Long

Thank you for the help. I guess my first instict was for Lat./Long. because I'm retired Navy. Again, thank you for the input.

I don't remember seeing any setting for grid lines in TopoFusion

maybe someone official will come reply here (i'm just a joe schmoe like you)

in the mean time '<img'> I made a tool to draw tracklines to simulate gridlines: see http://tera.kuren.org/gps/index.php

We don't support grid lines yet, so these GPX files of grid lines are a pretty cool idea.  Thanks for the link and work on that script, Kuren.

Maybe some waypoints for each gridline with "-47", etc ?

We do plan on adding support for UTM and lat/long grids.  I know they can be very useful when using maps in the field.

Yes, the UTM coordinate system is much easier to use out in the field because it is a decimal system, and it's easier to do the math in your head when eyeballing a position on the printed map.

I finally got around to throwing together an app that produces a 9x9 UTM grid centered around a user provided point, spaced 1000 meters apart, and labeled in the units of hundreds. I wrote it for my own use to produce a grid for 1:24000 scale maps for hiking. It is not generalized and will only produce a grid to that dimension. It produces a pretty good looking printed map if the 2500 x 1875 export size is used, and the fonts are at least 20pt (it looks pretty bad on screen, but the printed map looks good).

Knowing your location in the wilderness is an important and potentially life threatening thing. The writer of this app takes no responsibility for the accuracy of the output. The user must verify the accuracy of the grids before heading out and depending on it for determining a location.

If you can accept that, feel free to try it out. It's a 16 bit Windows console program that requires manually entering the UTM coordinates and parameters (sorry 'bout that).
