Goals and Objectives
The goal of this exercise is to become acquainted with the
process of downloading data from various internet sources, importing the data
into ArcGIS, joining data, projecting data from these sources into one
coordinate system and constructing a geodatabase to store and edit the data.
Methods
Data for this lab was obtained through many different web
services, such as the USGS National Atlas, the USGS National Map Viewer, USDA
services, and many others. A shapefile of US railroads was downloaded from the
National Atlas data and documentation service. The USGS National Map Viewer was
used in order to obtain both NLCD 2006 Land Cover Data and a National Elevation
Dataset (1/3 arc Second) for Trempealeau County, Wisconsin. The USDA Geospatial
Gateway was accessed in order to acquire Land Cover Cropland Data for the state
of Wisconsin. By using the USDA NRCS Web Soil Survey, SSURGO data was
downloaded and retrieved with the help of Microsoft Access. All the different
data layers can be viewed at once in the map below.
