NC Realistic Yield Expectation Mapping

In collaboration with Dr. David Krause (NCSU Soil Science), I built the NC Realistic Yield Expectation Mapping (RYE) application. The application takes advantage of SQL Server spatial functions. It draws RYE tabular date from the Realistic Yield Expectation tool at NCSU. This data was produced as part of a multi year collaboration between NCSU and NCDA&CS. The mapping capability had long been desired. The site also uses the Google Maps API, WMS generated by ArcGIS Server, Ajax (via jQuery), and the Open Street Map API.

Google Earth Enterprise

In 2006 NCDA&CS aquired an Enterprise license for Google Earth (GEE). I managed our installation. Caching over 20TBs of imagery, terrain, and vector data. Additional web resources, i.e. weather, were also included. The Google Earth Enterprise Client (EC) provides a rich 3d viewier that does not require advanced GIS training. This allows decision makers and field staff the ability to perform fairly simple analysis like measuring, simple drawing, and color coding (choropleth).

The EC has been used for situational awareness. The drought of 2007 had a large impact on North Carolina farmers, particularly grazing animals, forage crops, and equine Data from the National Drought Mitigation Center was used extensively in the North Carolina Hay relief effort. Visualization of the geographic and temporal data was a valuable tool for communicating the extent drought. The Hay Relief effort went on for almost a year.


Extending the capalities of the 2d Google Enterprise maps, I have built 10 WMS's. PERL scripts scrape GEE 2d databases to return OGC compliant WMS to a variety of clients. These services are publically available and recieve thousands of visits a month. WMS Site

NC Craft Dairy

In 2014 I built an online mapping application for the Marketing Division of NCDA&CS. The map shows locations of Craft Dairy products in North Carolina. If the dairy producer welcomes guests, there is a link for directions to the site, and a link to their URL as applicable. Marketing division employees have access to an editing site, where dairy firms can be entered and edited. Visit Craft Dairy Site

Ice Storm February 2015
In February 2015 a large winter storm was predicted. The NCDA&CS Food and Drug division requested a map such that should the storm occur, they would have a head start in coordinating their efforts. Scouring the National Weather Service (NWS) can yield a lot of information. I found ice and snow prediction data needed for mapping in anticipation of an ice storm. NWS serves the data in the KML format.

There are a lot of Food Firms in North Carolina. The Food Firm points represents all stores, warehouses, and manufacturers.
Agriculture at Sea Level
This map took several days to process. I clipped the State's 20 foot DEM with crop land data to identify the areas. The processing took 48 hours! Aquiring the crop land data was a challange in and of itself. The FSA has not released that data since 2007.

Below is a detail of crop land to illustrate the detail of the DEM. The area is just east of Lake Mattamuskeet on the border of Hyde and Tyrrell Counties.
Hay Relief Effort
Communicating areas where hay and forage was needed aided in efforts to help farmers and horse owners. I was given a spreadsheet with county names and bales of hay needed in those counties. I joined the a county shapefile to the spreadsheet based on the county name and used a custom icon as a proportional symbol.
This map took 2nd Place at the Raleigh GIS Day. People called it the "Green Ho-Ho Map" due to the custom "Hay Bale" icons I made. Initially they were yellowish, but I was told that hay is green, straw is yellow.
Fire Ants
The Animation Toolbar in ArcMap makes "movies" based on time stamps in the attribute table. I produced this clip for the Red Imported Fire Ant Program of the Plant Industry Division - Protection Section Entomological Services. The customer was so happy with the movie, that I got the opportunity to train them to make their own. Since 2008, Red Imported Fire Ant Program has made their own maps and animations!

Animal Health Programs

At NCDA&CS, the Emergency Programs division, manages the Animal Health Programs (AHP) database and application for the Veterinary Division (VET) of the. AHP data is sensitive and not subject to the Freedom of Information Act (FOIA). The AHP is built in partnership with animal industry partners. Industry provides much of the data. The AHP is a trusted repository through which the VET division and idustry can share information and collaborate.

I had to secure permission from the State Veterinarian to show these images. Care has been taken to not identify individuals or precise locations. Apolgies for the redactions.
One of the tools I have built within the AHP is Animal Disease Mapping. This interactive interface was built with C#, JavaScript, MS SQL Server, and Google Maps and API. Using the Jquery and Underscore js libraries made the site very interactive.
Users can generate buffers around farms. Once a buffer has been generated (illustrated by the violet circle) a table will appear beneath the maps, showing the farms within the buffer, as well as a straight line distance to the index farm. This table can be exported as a CSV file. For the PRRS disease, a link also appears that will let users view genetic sequences for instances of PRRS on the farms in the buffer.
Another feature is animated time progression. Users can progress week by week, forward or backward through an disease. The progression can also be animated, advancing itself, one week every 2 seconds.

Raleigh History Museum and the Civil War Breastworks

Ernest Dollar, Director of the City of Raleigh History Museum, reached out to me with an idea. He wanted to see if the Civil War Breasteworks, an earthen fortification, was visible in the LIDAR data. The Breastworks were built around Raleigh to defend the city from a Union attack. Ernest provided a map, shown below, that shows a section of the Breastworks that runs from the Mordecai / Roger’s Woods area east to the north of Peace University to the other side of Capitol Blvd.
I used the Warp tool in ArcGIS to "Ortho-Rectify" the map image Mr. Dollar provided and digitized the some lines to represent the Breastworks.
The line work was overlayed on the DEM. Given the amount of development in the area, and the nature of the earth embankments, it is not terribly surprising that the Breastworks are not readily apparent in the DEM. There may be an area on the south side where this experiment would yield results.
A local historian, Karl Larson, told me that prior to the construction of the extremely high density housing, just north of Peace University, some portions of the Breastworks were still there.

Carolina URISA

For the last year, I have had the privilage of serving as a board member for Carilina URISA (CURISA). In an effort to identify under represented area, I made a map for the board with proportional symbols for towns with members:

Boy Scouts

The Occoneeechee Council of the Boy Scouts has a camp at Kerr Lake, near Townsville, NC. Mapping of the camp grounds has always been very rudimentory, on paper, and hand drawn. I used a GPS to map all of the facilities, and published it to a public Google map.
