Topic : Working with Statsgo Soils
Data and Land Use
|
Getting Pecos Soil For this homework, I used the STATSGO
coverage for New Mexico to get the soil data and change the symbology. I
added the Pecos-huc and used the clip function from Arc toolbox to set the
soil information for only the Pecos-huc and changed the name to Pecos soils.
Next, I used the join and relate functions to join and relate the attribute
table of the Pecos soils with the information provided in comp, layer, and
mapunit tables that I added earlier. I then had to select the properties of
the map unit ID NM 963 and copy it to an excel file. From the excel file, I
deleted the columns I did not need to answer the homework questions and did the
necessary calculations. |

Land
Use for Pecos Huc Next, I downloaded the land use data from
rgis.unm.edu for Fort Sumner and Santa Fe. I worked with the properties of
Fort Sumner to classify by LUCODE, classifying method to equal method with
eight classes and manually entered the break values. I entered the break
values, changed the labels and colors. For Santa Fe, all I had to do was
import the symbology of Fort Sumner. I used the merge tool from Arc toolbox
to merge the land use of Fort Sumner with Santa Fe. |

Use of Intersection Tool Next, I intersected the land use and soils
data layers. Now when I open the attribute table, I am able to see both the
soils and land use data in one table. |
