[mapguide-users] Calculating a Euclidean Distance in Javascript

[nclayton]

Hmmm...something's not lining up right.

Here are my test values:

Start Point
x1 = 782968.222103
y1 = 1774880.116909

End Point
x2 = 783044.338
y2 = 1774867.244367

I used this formula in php:

$distance = sqrt(pow($x1 - $x2,2.0) + pow($y1 = $y2,2.0))

This gave me a value of 77.19671051057

$srsMap->MeasureEuclideanDistance($x1,$y1,$x2,$y2) gave me 23.529604265472

It looks like I'm using the same formula, but I am getting a dramatically
different result.
