Rio Pecos Watershed
	This assignment is really a great challenge to understand the soil data. I used CEGIS account for soil data, RGIS website for land use data and couple of features from previous homework. For this assignment I used couple of new tools from Arc toolbox (such as: Clip, Merge, Intersect) and finally produce an atlas for “Pecos Watershed”. First, I collected soil data from the CEGIS account and added to ARC map. I clipped the data from all of New Mexico to the Pecos watershed. I joined and related the soils tables data. To calculate some properties, I exported several data features in Excel. Land use information was added from the RGIS website. Because the append function on my computer did not work, I used the Merge function in ArcGIS 9.3 two join the two polygons that cover the Pecos watershed. I then intersected the output polygon with the clipped soils information to obtain a single polygon with the soils and LU codes for the Pecos watershed.
