Huffwx Posted November 20, 2010 Share Posted November 20, 2010 Pretty cool....Katie we could use your talents around here more often. Love the map work. She should have a mandatory training course for anyone who WANTS to post a map. We've had some real treats over the years map wise. Link to comment Share on other sites More sharing options...
mappy Posted November 20, 2010 Share Posted November 20, 2010 I will echo the compliments. Awesome map! I have already showed it to a few friends looking for information on last winters snow...they were also impressed. Great work! Pretty cool....Katie we could use your talents around here more often.

THEREALTOR1 Posted November 21, 2010 Share Posted November 21, 2010 Will always be a classic Huff, with this one here I love that map. I just wanted to echo what many others have already stated in here, those maps are awesome. Great Job! Even looking at them now takes me right back there.

wxmeddler Posted November 22, 2010 Share Posted November 22, 2010 I believe the Elkridge reading, during the 5-6 storm a deformation band set up right over them, coupled that with orographic lift from the Maryland fall line. There was for a period of 4-6 hours of 4-5"/hr snowfall rates there complete with thundersnow. Very very local, this band was no more than 5 miles across.

Eskimo Joe Posted November 23, 2010 Share Posted November 23, 2010 I did. How did you construct the dataset for snowfall? Did you compile information into an excel table, then a shapefile, then a DEM followed by a raster? Link to comment Share on other sites More sharing options...
mappy Posted November 23, 2010 Share Posted November 23, 2010 How did you construct the dataset for snowfall? Did you compile information into an excel table, then a shapefile, then a DEM followed by a raster? Yes and no - yes everything went into an excel sheet... city name, snowfall, lat and long (in some cases we had county listed but it was important for the map) and then I created a shapefile. I used Lat/Long rather than Northing/Easting because I created the map using a WGS coordinate system instead of State Plane since we had data from different states. As for the the mapping process, I ran a process called Inverse Distance Weighted (within the Spatial Analysis extension). IDW in laymens terms fills in the gaps between points and their values by giving more weight to values closest to a particular point and less weight to values further away to a particular point. It was this process that created the filled in contour areas. I used a variable distance rather than a fixed one so the program could reach out as far as it needed to between points to fill in the gaps. Does any of that make sense? I assume you are familiar with GIS since you asked. Link to comment Share on other sites More sharing options...
RIC Airport Posted November 27, 2010 Share Posted November 27, 2010 Thanks again, Katie. I think we should do seasonal maps like this again in the future. Although I'm sure 2009-10's numbers will be hard to come by in the near future. Link to comment Share on other sites More sharing options...
winterymix Posted November 27, 2010 Share Posted November 27, 2010 To mapgirl18; nice skills. I agree will all the compliments listed above. Here is my location: Latitude:39.4775799° Longitude:-76.796499° We had a seasonal total of about 86.5" Link to comment Share on other sites More sharing options...
