Nitrogen Point source Data,

Hi for the Nitrogen point source layer, we discussed using circles to represent each point source (nitrogen polluter). The size of the circle would relate to the amount of nitrogen, and the color of the circle would represent the trend of the point source, whether nitrogen pollution was increasing or decreasing over the period 2007-2014. Is it possible to display also the following metadata associated with each point source facility? Please find the raw data at the following attachment Great Lakes to Gulf Raw Data.xlsx

Facility Name

City

State

HUC 12

Average total pounds per year (2007-2014)

Percent change total pounds per year (2007-2014)

I am proposing we use the below groups to classify circle sizes

class 1 0-25 average lbs per year

class 2 0-50 average lbs per year

class 3 50-100 average lbs per year

class 4 100-200 average lbs per year

class 5 200-500 average lbs per year

class 6 500-1000 average lbs per year

class 7 1000-2000 average lbs per year

class 8 2000-5000 average lbs per year

class 9 5000-10000 average lbs per year

class 10 10000-20000 average lbs per year

class 11 20000-50000 average lbs per year

class 12 50000-100000 average lbs per year

class 13 10000-1000000 average lbs per year

class 14 1000000-3500000 average lbs per year

I am proposing we use the below groups to classify circle colors The color of the circle will indicate the change in nitrogen contribution over the period 2007-2014)

Class 1 100 -99% decrease

Class 2 99-50% decrease

Class 3 50-2% decrease

Class 3 2% decrease - 2% increase (no change)

Class 4 2-50% percent increase

Class 5 50-100% increase

Class 6 100-1000% increase

Class 7 greater than 1000% increase
