latitude longitude - Moving Collada file Lat Long -

-

i append collada file plug-in, , move (append.child, remove.child, append.child, etc) based on small latitude , longitude increments. when latitude increment = longitude increment, however, file moves in rectangular fashion , not square fashion. doing wrong? shouldn't "path" collada file travels "square"?

the increment in both directions (lat or long) same increment (0.00001499817). in trying figure out, noticed "circle" polygon code shows oval unless place along equator.

should assuming latitude increment equals longitude increment in earth???

anybody know might going on? thanks. paul

should assuming latitude increment equals longitude increment in earth???

do assume earth perfect sphere?

do assume latitude , longitude lines evenly spaced out?

to quote else quick google search

longitude east-west (right/left) measurement on map. goes 180 degrees west 0 (through greenwich, london, uk) 180 degrees east. 180 degrees west or east same line - in middle of pacific ocean.

there 360 lines of integer longitude.

latitude goes equator - 0 degrees, north north pole @ 90 degrees north. or south south pole @ 90 degrees south.

there 180 lines of integer latitude.

technically, you'd have number of possible lines infinite. since between 2 lines choose, no matter how close are, can fit bunch more in between them.
