FINAL PROJECT – GISPutnam County Trash, Recycling & Loads

Jan 2009 – Aug 2011

The Intent of Design:

To provide a ‘snap shot’ view graphically showing usage rates that represent categories of trash or loads.

Primary Map displays graphical data representing location and material in Tonnage, (Most complete Data Acquired)Secondary Map (Inset) – displays additional data but in loads

Data received from customer did not correlate Loads to Tonnage

The Issue:

How can I graphically display statistically data of garbageand recyclable materials using GIS for evaluation of the Utilization of County Trash Sites?


Jan 2009 – Aug 2011


Jan 2009 – Aug 2011


Jan 2009 – Aug 2011

Data Collection

• GPS Points for 11 Trash Sites via Garmin GPS Unit

Data Collect

ion

• Trash Statistics from Advanced Disposal via Mr. Jon Hipp• Permission granted from County Manager Mr. Paul Van Haute

Data Collection

• From Georgia Clearing House• Georgia Census Tracts• Georgia Roads• Putnam County Boundary


Jan 2009 – Aug 2011

Initial Map Generation

• Verification of Definition and Projection for:• County Boundary• Census Tracts• Georgia Roads

• Feature layers clipped to County Boundary


Jan 2009 – Aug 2011

• Points from GPS Imported in• Two points corrupted

• Required Digitizing Shape file• Updated Attribute Table• Imported Raster Image to

locate points

Initial Map Generation:


Jan 2009 – Aug 2011

• Theissen Analysis Polygons applied• Provides equal distance between

sites• Suggest possible coverage areas

of sites• Roads Imported

• Selected by location using ‘Buffer’• .25 miles from each site• ‘Highways’, ‘Roads’, ‘State

Routes’• Saved as separate feature layer

Secondary Map Generation:


Jan 2009 – Aug 2011

Data Incorporation:• Trash Statistics Provided by Advanced Disposal

• Two Forms:• Tonnage: MSW / C & D / Tires / Recyclables• Loads: Brush / Metal / Tires / Recyclables• (No Data given on what tonnage comprises a ‘load’)• (Consequently Tonnage is displayed on Primary Map• loads displayed as Map Inset)

• From Excel, Data Manipulated via pivot tables• Data joined to site points attribute table under ‘RefName’

Symbology:• Population Tracts• Progressively darker as population increases• Transparency increased

• Roads• Thicker and darker• labeled

• Buffer• .1 mile around sites• selected Charts• selected Pie Chart and components from within Attribute table• set background to hollow and no line• This enables the data selected to be displayed as the symbol as the site itself

• Multi-Ring Buffer• Used instead of Buffer as Buffer lines overlap and draw inside adjacent rings• Use of Multi-Ring Buffer joins the ring so further tool of intersect not necessary• 3 mile ring added to suggest sphere of influence


Jan 2009 – Aug 2011


Jan 2009 – Aug 2011

Selected Data Feature: - This feature was used as the attribute table for all the sites was tied here


Jan 2009 – Aug 2011

Symbology: - Under ‘Show:’ select Charts, and then which type of chart you desire.

- Under ‘Field Selection’ select which fields you want compared, (This comes from the attribute table)


Jan 2009 – Aug 2011Symbology:- Symbol color can

be edited here BUT field name cannot it is as it appears in the attribute table.

- Set background to ‘hollow’ and ‘0 outline width’. Effectively this gets rid of all graphics except for the actual symbol used (in this case a pie chart).


Jan 2009 – Aug 2011

ArcMap compares the data from the attribute table and utilizes the data within the symbol itself.

Data was double checked against charts created via Excel, the result was an accurate graphical representation of the data.


Jan 2009 – Aug 2011

Without the associated charts showing numerical data the Map only shows which site collects more of what category of trash – Utilization! Which is the Goal for this Project.


Jan 2009 – Aug 2011

In this example (view the snippet of the attribute chart at the bottom) Flat Rock clearly collects more tonnage in Tires but comprises roughly 25% of all trash at that site. When compared to Twin Bridges which shows roughly 45% of its collected trash is Tires.

Additional Data:

• Created new Layer• copied county boundary feature• copied and modified site to reflect Load Data

Map Inset – Graphically displays data for Loads

• Via Charts• For Total Tonnage by Site• For Total Loads by Site

• Via Pie Charts• Specific Example of heaviest used site

• Tonnage• Loads

Statistical Data Provided


Jan 2009 – Aug 2011


Jan 2009 – Aug 2011

The Map Inset, significantly smaller shows the % of trash category per site in LOADS. In previous slides about Tires in tonnage for Twin Bridges which showed roughly 45% for total trash collected this inset shows that by far the most loads went to Brush Collection.


Jan 2009 – Aug 2011

However as presented in the Final Map, raw data is needed to make any sense. Above are two charts created via excel for the overall Tonnage and overall Loads per site.


Jan 2009 – Aug 2011Finally; The heaviest utilized site was picked to show how its data is broken down. (See previous slide)

It would be impractical to show all 11 sites on one map; however, the statistical data along with the map and this presentation were forwarded to the customer.

Remember the goal was toshow OVERALL UTILIZATION.


Jan 2009 – Aug 2011

Analysis• Via Map

• More affluent areas of the county (Northeast, East, and South)• Indicate more recycling• Indicate more loads of brush

• Via Data from Excel• Next several slides indicate cyclic patterns for data time frame provided
