Anyone know what the point of this code is from the CartesianPolyFilterBuilder:
<code>
shape = getShapeLoop(shape, ctp, latX, longX, latY, longY);
if (longX2 != 0.0) {
if (longX2 != 0.0) {
if (longX == 0.0) {
longX = longX2;
longY = 0.0;
shape = getShapeLoop(shape, ctp, latX, longX, latY, longY);
} else {
longX = longX2;
longY = -180.0;
shape = getShapeLoop(shape, ctp, latY, longY, latX, longX);
}
}
</code>
Why the double check on longX2? I think it's trying to get at edge cases
(based on earlier statements to do with prime meridian and the 180 longitude.
Also, I see the following comment:
double startY = beginAt - startX ; //should give a whole number
Yet, in debugging, I don't see how it is ever a whole number, b/c, AIUI, the
left side of the decimal of a box number is the X value (latitude) and the
right side of the decimal is the Y value.
FWIW, I'm testing how all this tile stuff behaves across the 180th degree
longitude (and it doesn't seem to be behaving well)
