Step 1 Structural Attitude Determination
Your task, due Wed, is to first digitize as many formlines as you can, as discussed in the tutorials.  By the end of this step you should all as many formlines as you think represents the overall structure of the map. 

After you are done with digitizing the formlines do the following:
1) Have the formlines layer visible (checked), then select all of the formlines by right-clicking the layer and choose Select all Features
2) In the map have formlines and DEM visible and right-click to choose Attribute/Style Functions> Apply Elevations to Selected Features
3) Export the formlines by rick-clicking the layer and choosing Layer>Export Layer
4) Choose Text file as the type and then in the dialog box make sure to have Tab Separator, X Coord Order, Export Elev checked, and Include Feature Attributes checked.

If you want read in another student's formline:
1) Drag the exported text file into GlobalMapper and you should be able to use the defaults (Points, Include Attributes and Treat 3rd Col as Elev).

Now convert your formlines to strike and dip values and visualize them in GlobalMaper. 
Open Matlab remember to:
a) set your paths before you run the command, to
b) go to the directory where you have the formlines
c) use single quotes around your filename (whatever that name is)
Then type at the command prompt in Matab the following:
>> readGMFeatAttWriteGMSD('your_formline.txt')
Then drag the file that was created from the desktop back into GlobalMapper.

You should see strike and dip symbols near your formlines. You should check that these are consistent with your formlines.  If they are not it is probably because your formlines did not have enough 3D extent.  That is, they sat all in a line, rather being in a plane.  The algorithm must have 3D extent in order to determine a best-fitting plane.

You should also check your strike and dip measurements to see that they are consistent with what you think the bedding is locally.  This is very much related to what you thought the bedding was based on your formlines.  That is, you were seeing a formline that made a V shape and you think that indicates bedding.  So does the strike and dip seem consistent with that V?  If not then delete that individual S&D.  You do not have to go back to the formlines.  Think of this as a cleaning phase.  There is no point in having symbols that you know are wrong.  I have placed my attempt at attitudes on the class GIS folder entitled "formlineCDC_SD.txt"  Feel free to look at these and use some of them too if you want. 

When satisfied with your strike and dip measurements go to Step 2
