Points have been added @cambro The final points file is titled "Points" the original is "Points0".

The original points data had azimuth (strike), dip, fault dip, fault dip direction, rake, rake angle, bearing and plunge

1) For the points of point_type "fold axis" I shifted the bearing values to the strike column and plunge values to the dip column

2) For the points of point_type "bedding" I determined from the map that the strike and dip values follow the right hand rule convention. I added 90 degrees the azimuth/strike column to create the dip_dir field.

3) For the points of point_type "fault surface" I subtracted 90 degrees from the flt_dip_azimuth column to get strike values.

Each of the fault surfaces points also has data for the rake azimuth and rake angle ( as well as strike and dip ). We may want to revisit this later.

@ItoErika I don't see a points.sql.gz file anywhere in the Ponca_Arkansas directory on teststrata

@cambro it should be added now
