Decimal Lat Long Grid Lines

Our Sheriff's Office has requested our maps be in Decimal Lat Long, as to match the e911 system.
When I select Decimal Lat Long, the map does not draw the grid lines, but prints only the notations and tick marks around the border of the map. How can we fix this problem?

    At the moment, it only shows the tick marks, no way around that. For what it's worth, the lat/long lines are all straight up/down or left/right, unlike the UTM grid which is skewed relative to true north. I can look into adding the lines instead of tick marks, but it's not currently supported.

    I was just going to ask the same thing: I cannot get Lat/Long grid lines to appear on my printed maps (either JPEGs or PDFs)--only the numbers and tick marks after selecting the appropriate checkbox in the Print menu. These grid lines would be really nice to have for us compass users.

    What is SAR Talk #95?

    I assume you are looking at CALTopo or SARTopo.

    Matt Cosand now works for them, and it’s about time someone asks again for the Decimal Degree Lat Long Grid Lines, have at it.

    Some day it will happen.

    And then there are the Mountaineers who use the UTM grid as True North, I have issues with that too.

    Have you tried talking about this issue with Matt Cosand of ESAR ?

    Bob, no, I don't know who Matt Cosand is. I only latched on to this thread because I had the same question that you raised initially; i.e., how to get Lat/Long grid lines appear on CalTopo printed maps.

    I'm just a regular hiker who uses both GPS and compass with a $20 annual subscription. For GPS, there's the UTM grid lines that appear, but for compass users, there're only the degree and minute tick marks that appear.

    I thought I was addressing Matt Jacobs for this issue. Maybe I got on the wrong thread (sorry :-( Is "SAR Talk" another product that Matt Jacobs develops?

    I believe Matt Jacobs is the developer of CalTopo and Matt Cosand (of King County Search & Rescue) started working for Matt Jacobs this last year.
    Back in Jan of 2018, I told our County’s navigation instructors that nation wide, e911 reports to First Responders and estimated 240 million time per year, the location of individuals that need help, and that few maps, if any are marked in Decimal Degree Lat Long.
    CalTopo came back to me too that adding the lat long lines to the decimal degree tic marks was not funded at this time – so why not now?

    I’ve also talked to Green Trails, they too see the need, but revisions can take years.

    SAR Talk might be a chat page that Matt Cosand developed – I don’t follow that.

    Guys -

    At the moment, all of our capacity is being spent getting the android and ios apps out as quickly as possible. For what it's worth, that was also the case a year ago as well, I just wasn't ready to talk about it publicly - there have been very few feature updates to CalTopo in the past year, and a lot of things have been pushed that I would have liked to have done.

    Best I can tell you is that I can take a look a this at some point after the android and ios apps are out of beta (ie hopefully by the beginning of summer). Sorry if that's not ideal, but there is a lot riding on the app.

    Matt – Your CALTopo maps are save lives almost every day, keep up the good work !

    From our initial page out by e911, to deploying the first responders, to locating the subject (often in mountainous terrain after dark), we use your topo maps every inch of they way, we are so spoiled.

    I am going to close this for now, but feel free to reopen it in May as a reminder, or sooner if both apps get out of beta before then, and I'll promise to take a look at it.
