My first city placefile. It first appeared on Grlevelxstuff.com in January 2008. It contains major city placefiles for the United States. There is one placefile for larger displays/resolutions and one for smaller displays/resolutions. Each set of placefiles also has versions that contain the city 'dots' and versions that don't.
Color tables, placefiles, and other items for the Gibson Ridge family of weather visualization products. Pull requests welcomed and encouraged!
If you are new to Gibson Ridge products (especially the use of placefiles and shapefiles), see the Gibson Ridge documentation here: http://www.grlevelx.com/manuals/gis/menu_gis.htm
AWIPS Cities
The AWIPS Cities placefile is a preliminary stab at converting data found at
to Gibson Ridge placefile format, with a minimal-effort pass (so far) at mapping AWIPS progressive disclosure values to different viewing thresholds in GR. More work is needed here!
Marine Zones Style File (style-files/Marine Zones.sty)
Use this style file combined with the shapefiles found here:
to display various marine zones under NWS forecast responsibility (tested and works with all coastal and Great Lakes marine zones).
Counties Style File (style-files/Counties.sty)
Use this style file combined with the shapefile found here:
to display counties as loaded into AWIPS.
I'm just starting to learn how to use GRLevel3 after relying mostly on Radarscope, and I just had some quick questions!
-What are the circles around the radar indicate? I read that they indicated the melting layer, but what is that and what is its significance?
-Is there a data source other then the NWS that is free? I've been looking at AllisonHouse, but as a college student it seems somewhat expensive (or is it worth the $11/month?).
-How do you interpret what kind of precipitation may be coming down in an area? I've used precipitation depiction on Radarscope, but is there anything of the sorts on Grlevel?
-What are some really cool or recommended place files?
Thanks!
