Long/lat Coord Measurement Question

[+KerryG]

This is probably here somewhere but I have searched here and in Google and couldn't find an answer.

 

I am trying to figure out how to calculate the distance between two coords but I couldn't find any info on how much distance is between two points other than in degrees which doesn't give me miles/feet. Can anyone point to a reference for that?

I think THIS might answer your question. This calculator allows you to enter 2 coords and get a distance.

GeoClac is another option for you.

Here's another easy to use calculator. It also allows you to project a point.

After a bit of using some calculators and some manual work, I discovered some nice software at http://www.gpsu.co.uk/ that does the trick nicely.

I used it to set up a 7 waypoint multi and check the distances and bearings between all points as well as distance between some points and the co-ordinates for some nearby caches.

Most GPS units will let you do this also, one way or another. How to do it depends on your unit model. My old Garmin 12 had an easy function for this, but my Map76 is a little trickier. If they are not too far apart you could also use also use the map screens measuring function.

I use the Sportrac map, and I if you put in the coordinates of point a and b then you can use the goto function and it will tell you the distance.

Another method would be to input the grids into Easy GPS and select one of the points as the orientation point. The distance to the other point will be given. This may be a bit too much trouble for a single set of points but if you have a lot of points and want to see which one is closest to a single point, it is a good method.

If you input the waypoints in your GPSr, you can easily find distance and direction. One easy way is create a route, which takes a few seconds. Your GPSr will show the distance and bearing between any two waypoints in the route you create.

Fizzymagic has written an excelent Windows program, GeoCalc that does what you want, as well as perform a few other useful caclulations. I use this program often in my duties as cache reviewer.

Here is a nice calculator (with some explanation):

If you need the formula, view source (javascript) of the page.

It is essential to use haversine formula, because regular one can't calculate short distances.

The answer to your question is a little tricky. One degree latitude is one nautical mile or 6000 feet. One degree longitude at the equater is also one nautical mile. However longitude degrees get shorter as you get closer to the poles .

Yes, you can find that here>
