3d. Creating a point feature class within the feature dataset

By now, the contents window of your geology feature dataset should look something like this:

Since we’re creating a geologic map, we want to also have a point feature class this will store our strike and dip data and display it on the map.  The steps in this part are very similar to when we created the line feature class, with a few changes.  Here’s how that is done:

1.  Right-click in the contents window, select New –> Feature Class.

2.  In this first window, name your point feature class.  Since this feature class will contain strike and dip data, an appropriate name might be “bedding”.  Don’t worry about the Alias.

3.  Make sure that the “Type of features stored in this feature class:” drop-down menu is set to “Point Features”.

4.  Click “Next”.

5.  In this next window, you’ll add two new fields.  Since bedding data contains two pieces of information (azimuth strike and dip amount- Arc is good about using Right-Hand-Rule for orientations so your bedding data should also use this convention), these two new fields should be “azimuth” and “dip”.  Set both of these fields to have a “Data Type” of “Short Integer”.  Set “Allow NULL values” to “No”, and make the “Default Value” zero.

6.  Click “Finish”.

7.  Done.  You should now see all three feature classes (contacts/ lines, bedding and topology) present in the contents window of your “geology” feature dataset.
