Web Soil Survey Notes
Note One: Creating an Area of Interest
Perhaps
the most difficult step of using the Web Soil Survey is the first part,
creating your area of interest. What I found to be the most effective method
for finding an area of interest is using the built in address feature that
allows for one to plug in an address and jump to that location. After locating
my area, the taskbar tools make it easy to select an AOI using the two red
polygon buttons next to View Extent.

Note two: Navigating The Area of Interest
Next
there is the task of navigating through the data the website has generated of
your Area of interest. To do so one can cycle through the soil map and soil
data explorer tabs at the top of the page. Soil map provides a base overview of
the soil types of your AOE and clicking on each soil type in the left hand
graph provides an overview of each soil type. Of great interest to me during
this coursework is the data provided in the soils data explorer tab. Here one
can look into soil suitability and limitations for use, soil properties and
qualities, and ecological sites to name a few. Of these suitability and
limitations for use offers a wide scope of useful information, such as
vegetative productivity and soil health depletion; a useful collection of
information in the field of wetland restoration. Ecological sites provides a
bevy of useful information such as dominant land use type across each soil, and
the dominant plant species.

Note 3: Exporting Soil Data
The last feature of Web Soil Survey that I used for my examination of this website, was the download soils data feature. Having used this site a few times during my undergraduate, exporting soils data from this site was a simple matter of simply clicking on the download soils data tab, clicking on create download link, and exporting the files to a secure location in my computer. Going a step further I also decided to play with the data files by porting it over to a free GIS software DIVA, with which I created the map below.
