mercator.proj4 evaluates to the +y_0=0
flavor, but then when the map object is rendered to XML the map srs
element becomes +y_0=0.0
while the layer srs
element remains +y_0=0
As rendering a map js object to its XML is done by carto, I noticed pile uses two distinct versions:
├─┬ carto@0.14.1
│ ├─┬ carto@0.9.5-cdb2
The 0.14.1 is used directly while 0.9.5-cdb2 is used by grainstore (does pile really uses grainstore?)
Found 0.0 hardcoded in src/pile.js line 1118, under options
I found that map and layer are using different SRS specification, for webmercator:
The difference seems to be only formal (y_0 being 0 or 0.0) but it affects engaging or not in a reprojection, which in turn triggers the visible tile issue reported in #31
