in thread Perl and Solving Trig/Converting GPS to x,y Cords

Given that the area between the +-70° latitudes covers 95% of the Earth's surface and 99.8% of the world's population; and the 0.2% inaccuracy represents a 0.00016 mm on a standard large scale (1::25,000) map -- or, you'd need a map 800 meters wide in order to be able to detect the inaccuracy between the actual and calculated position of a point -- the "general case" is not required for the vast majority of cases.

Hence why I passed along the information that the general case is not usually required, without in any way impugning the accuracy of your post.

I was simply pointing out that unless you run an airline -- and one hopes they know what they are doing -- the simple 2D trig approach to mapping GPS coordinates to map coordinates is usually good enough.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

[Discipulus]: marioroy did you know zentara is back to themonastery? he was used to be one of the best parallel programming monks
[makita]: sign_types parameter in XML::Compile::WSS ::Signature Does have anybody experience how to use it?
[makita]: Need to sign more elements but all types I put in array are ignored. And is always signed only the body
[Discipulus]: no makita sorry. i see in the synopsis of the module: "WARNING: Only limited real-life experience" might be better compose a SOPW with some code example and data
[Discipulus]: ..or inspect the source code of the module
[makita]: I am doing this:
[makita]: my $sig = $wss->signature( schema => $wsdl, token => $token, sign_types=>'wsa: Action','wsa:To', 'wsu:Timestamp', 'wsa:MessageID',' SOAP-ENV:Body', signer=>DSIG_RSA_S HA1, public_key => $cert,
[Corion]: Oof, I haven't done much with signing SOAP requests. markov is usually somebody good to ask via mail ;)
