Upload Route (Pocket Queries) fails near Prime Meridian with KMZ

[+EntropyEndeavor]

I was trying to find a cache that is listed exactly on the prime meridian, so I made a route with only two points on either end of the UK.

 

When I uploaded the KMZ file to https://www.geocaching.com/my/userroutes.aspx with "Upload a Route" It looks great on the route preview. However, after the route has been saved it turns out quite far off if you look at it again under "Your Created Routes".

 

The problem is that the KMZ is storing the longitude as a floating point using E-notation. When it is being converted to GPX the e-006 is being ignored and so the really really small number close to zero is being treated as a large number. (Google Earth created the KMZ with the E-notation by default.)

 

Relevant lines:

KMZ (decompressed):

			<coordinates>
				5.271868201983665e-006,50.78895172358102,0 2.148130113788227e-006,53.75847697963745,0 
			</coordinates>

GPX:

<rte><rtept lat="50.788952" lon="5.271868" /><rtept lat="53.758477" lon="2.14813" /></rte>
