 "teaser_html": "<p>After about 20-years of making weather maps an old way [GrADS], I\u2019m in the process of adapting code and scripts to be more Google Maps oriented but with some tricks up my sleeve to increase the quality and customization. The main issue with web Mercator is not being latitude and longitude based but on tiles zoomed at various local, regional and global scales.  Raw weather model data is processed in latitude and longitude space (EPSG 4326) and you cannot warp the web maps to latitude and longitude without losing the quality of the map because it become distorted.  So, we need to go the other direction and assemble the maps with web Mercator.  I\u2019m not aware of a sturdy, operational workflow or business that provides this, so we\u2019ll be on the ground floor of something new and cool.  The end result will be more broadcast TV style mapping and pre-rendered output that should be eye-popping.</p>",
