From Here To There

[StripeMark]

Does anyone know of a web site or a java applet where you can:

 

(1) plug in 2 sets of coordinates and have it come back with a distance between the two in miles, or feet, depending on the distance,

 

example of 2 sets: 38 30 45.5N 94 02 28.6W and 41 28 40.2N 93 25 20.5W -> what is the distance between these points?

 

and

 

(2) enter in a latitude/longitude and a heading and distance, and then have it come back with a new set of coordinates,

 

example: start at 38 48 32.8N 94 29 20.0W and head 38.5 miles to azimuth 202.5 degrees -> what are your new coodinates?

 

Some kind of stand-alone program would be best, but I don't know if something like that exists.

 

Thanks!!!!

for #1) - ran across this one a while back:

Thanks Ernmark! That "sort of" works, but it rounds to the nearest mile. I was looking for something a little more precise.

stripemark,

 

I have mentioned it before.

The GPS Trackmaker will do all the functions of which you ask.

 

It will even give you ans azimuth of the points.

 

DGTV

 

Scroll down and on the left column get GPS Trackmaker.

 

under tools options you can change it from feet to miles or meters or or/.

 

ADD.

You can now also use it to view those points in Google Earth.

You can also see the points in TOPO or any of the other freeware mapping programs.

You will have to play around with it and make sure to use the help file.

 

There is just too many thing to explain on how to do it.

NGS supplies programs in their Geodetic Toolkit called "Forward" and "Inverse" that do this to super precision in meters. You'd have to convert to feet, yards, or miles yourself. There are on-line calculators and downloadable DOS programs.

 

Their distances are on the ellipsoid model of the earth (approximately sea level). The correction for distance on the surface is negligible for most of us, amounting to 1/4 foot per mile for each 1000 ft. of elevation.

 

A little tip: I spend a lot of time converting between dd.ddddd dd mm.mmm and dd mm ss.s formats for various purposes. It doesn't tell you so but the input to their programs can be in any combination of these and it seems to work ok.

bill93, THANK YOU!!!!!!! that is exactly what I was looking for..... and they are even DOS programs!

 

I was looking on the NGS, but never found my way to that page.

 

Thanks again!
