To make a contour map with QGS and Mbtiles:
http:// mapbox. com/blog/ contour- lines-density- mapping/
first interpolate the points to a raster, then create a contour map.
Next import the contour shapefile into tilemill and style.
Unfortunately, this data is not well represented along with a vector hazard map. This is because the interpolation pixel resolution must be low when interpolating the global data, and thus the contours do not closely follow the source data.
I would like to further investigate this, but instead on interpolation and rasterization, I believe a better result can be achieved using the QGIS contour plugin.
