    Accuracy is within 100 feet of the exact location, while in a dense and super-gay area like Chelsea isn't a huge difference from say 50 feet "away" as indicated on the app, if you're in the suburbs you're pinpointed down to a few houses, and if it's in Iran, you're screwed.

    Direct link to the tool below, since half of you are probably skip straight to stalking mode anywayrolleyes.gif

    Well, gay.com has got even worse... they show a road map direct to your location when anybody clicks on your profile. Whether they're a member of the site or not. icon_eek.gif

    I deliberately put in a zip code 75 miles away from my location for this reason. And also because when any random person types "gay.com" into a browser, it displays the pictures of the nearest 20 or so guys. In a rural area, this can pinpoint every gay in the county, to anyone who wants to know. If you're in a large city, it would be a pretty random occurrence for your picture to come up. But somehow, they have zeroed in on my actual location.

    I was feeling naughty and installed grindr to try it out for the 1st time ever. icon_lol.gificon_lol.gif

    Yes, I want to be hunted down. That's kinda the purpose of the app, isn't it? icon_lol.gif

    This isn't a flaw of grindr, it's a flaw of any application that shows you precisely how distant any user is from you.

    The procedure to find the user's location is very simple:

    You are in location "L1" and user "A" is distant "M1" miles from you.

    Now move to location "L2". User "A" is now distant "M2" miles from you.

    That's all you need to know to triangulate user "A"'s location.

    I recall using this method in the U.S. Military with map and grids to help determine a distance. Good point

    technically the above method will give you TWO potential points as it is described. To get an exact location via triangulation, a distance measurement must be taken at three distinct points, hence the "triangle" in "triangulation.

    Two points is all you need.

    You are at point A and user X is N miles from you.
    You now are at point B and user X is M miles from you.

    You already have a triangle.

    The distance A-X is known --> N
    The distance B-X is known --> M
    The distance A-B is easily calculated.

    There you go.

    The location thing isn't even accurate. It's usually off by a couple miles so you can't track down anyone with it. And even if it tells you you're 2 miles away, there are literally thousands of people 2 miles away.

    Mine here shows users with an accuracy of up to 30 meters. You don't seem to have understood the concept of triangulation...

    My Grindr will say the person is 3 miles away, but then when I put in their address Google Maps will say they are 5.7 miles away. I tend to trust Google more than Grindr. Mine often says someone is 1557 ft away. It doesn't matter. It's Grindr...that distance thing is completely inaccurate. Triangulation doesn't work if the distance is completely off...icon_wink.gif

    The examples in the story show that on-line utilities can pinpoint locations to within single buildings in the city - e.g. House Republican Committee offices. They probably get average values from several queries. In my example of gay.com, you don't even have to go to a utility - the profile page gives you a street map to the exact address. As mentioned in the story, for rural addresses, plus or minus 1000 yards is as good as exact.

    And Bachian doesn't get to navigate my boat. If you have only range but no bearing from two points, there are two possible solutions, 180 degrees away from each other.

    If you live in a rural area and think there are people actually willing to go to all that trouble to track you down and you are afraid of these people actually finding you in person, then just turn off the show distance tab.

    Well, I can accept being called Cartesian... icon_lol.gif

    If you don't know point C, but you know points A, B and the distance A-C and B-C, you can find C. That's correct in a Cartesian plane. Orthodromically, well...

    yes, but unless you actually know the bearing of those measurements you get two triangles. If ALL you know is distance, then you don't know if X is N miles due southwest or N miles due northwest. You get TWO possible triangles. Range measured by distance alone isn't a line, its a circle with the distance as the radius. Imagine two circles drawn so that they overlap. The points at which the circles meet are the convergence points for the two ranges and are each potential locations of "X". In order to determine unequivocally which one is the actual location of X one must either take a third range measurement from a third point "C" or there must be a bearing on one of the measurements A-X or B-X. A third range circle from point "C" will intersect one of the two intersection points of the range circles from "A" and "B".

    There are much easier ways to find people than with Grindr's shitty distance thing HAHA. I'm sure Google or FaceBook has violated your privacy much more invasively. If on the off chance, some one does actually find you somehow despite Grindr's inaccurate distance ranges, just tell them to fuck off and that you're not interested and that they wasted a ton of time.

    I'm sure if safety was someone's concern, they can give a zip/postal code a few block away from their actual location. Can't imagine this to be a major issue.

    Apparently you're mad because no one will message you.
