NM963

This really puzzles me. I’m not sure whether you want NM963 in NM and TX or just NM. I think you’re getting both. There are 8 components.

 

                        Comp               name                         %         hi, lo slope    sfctexture

                          |                        |                              |                  |                  |

The percentages of A, B, C, and D for this soil are 0, 2 (intermediate b/t sand and clay), 12 (intermediate b/t sand and clay), and 86 (clayey, poorly drained soils).

 

The average slope for each of the 8 entries is 9, 8, 49, 2, 25, 27, 55, and 20, which is all I can figure out for ‘predominant slope’.

 

However, there are only 2 outcrops of the soil in NM963.  

 

Dominant soil texture is Regner (27 + 7 = 34), which is CL = clay loam. The other major soil texture is FSL = fine sand and loam (Latom at 27%).

 

I had to look elsewhere for the streams data, but it looks as if the 2 pieces of the map below that are NM963 are drainages. But I don’t know whether it makes sense b/c I don’t have elevation data to see how far down the streams cut. My impression is that streams usually have sandy beds, but I suppose a clayey bed would not be impossible.

 

Vertically integrating soil properties over the layers

This took some time to figure how to get the dbf files from arcmap to excel. And I found that I can only save the active sheet of the file, so I shouldn’t have tried to put all three pieces – layer, component, and mapunit – in one file w/ 3 tabs.

 

NM963 has 8 sequences (SEQNUM), of LAYER numbers:

1 > 3

2 > 2

3 > 1

4 > 3

5 > 3

6 > 2

7 > 3

8 > 4

 

See the separate part of the assignment for the spreadsheet of calculations and information. (I don’t know how to embed the landscape spreadsheet nicely into my single web page assignment.)

 

 

 

 

 

Land use

In the following map, the bottom rectangle is Santa Fe and the top one is Fort Sumner. I have used the equal intervals LULC and classified w/ 8 classes. This classification puts the same range of values in each class. This doesn’t show the natural breaks that the Anderson codes show (2 maps down).

 

 

 

The map below shows both quads w/ the same color scheme. Fuchsia is forest, ochre is rangeland, the small amount of yellow on the right side of the map is agriculture.

 

 

 

 

The layer below is the merged land use layers. This took a considerable time to figure out how to do.
