Exercise: LaSal Mt. Soils

Dissolving & Taking a final Look:

(For an ArcView 3.x option)

Add the final results coverage (lasal_soil) into your ArcMap session and classify the soils by the MUID value field.

Results: ( quad_append_results )

The last step in this part of the exercise is to remove the quadrangle boundary lines by using the dissolve tool.  Depending on whether you want a shape file or an Arc/Info coverage as the output will determine which tool that you will use.  Within the ArcMap session you could use the GeoProcessing Wizard but this will only output a shape file. 

For this exercise we want the output to be an Arc/Info coverage, so we will use the ArcToolBox.  Start ArcToolBox, unless it is already going, choose the ‘Data Management tools’ toolbox, then choose the ‘Generalize’ toolbox, then double click on the ‘Dissolve’ tool. 

Results: ( arctoolbox_dissolve_menu )

Results: ( arctoolbox_dissolve_dialog )

For the input coverage choose the lasal_soil coverage, make sure feature class is Poly and for the dissolve item choose ‘MUID’, the same field values that you classified by.  For the output file call it ‘soils’ and make sure it is in the ‘lasalmt’ directory.

Results: ( arctoolbox_dissolve_outputfile )

If your dialogue is correct choose OK.  The processing could take a few minutes.

Add the dissolved coverage called soils to the ArcMap session and classify by the MUID value field.  Your final coverage should be all the soils in the LaSal Section and they should not contain any Quadrangle boundary lines.

Results: ( arctoolbox_dissolve_results )

Be sure to save your ArcMap session, give it a name similar to lasal_mt_soils. 

(This is the End of the LaSal Mt. Soil Exercise.)
