Functions

tfr_list() #Returns the basic list of TFRs
#convert_degrees boolean is optinal defaults to true, converts coordinates from dms to dd ("26.02333333N", 097.12833333W") >>  (26.02333333, -97.12833333)
parse_tfr(notam_number, convert_degrees) #Parses a notam number in full format like (1/8339) and will return the details of the tfr. 
get_list_and_parse_all(convert_degrees) #Downloads TFR list and parses all combines details with list and returns it. 
save_detailed_all(filepath) #Does get_list_and_parse_all() and saves as a json, filepath is optional default is ./detailed_tfrs.json
save_detailed_all_cleaned(filepath) #Does get_list_and_parse_all() but also cleans some broken tfrs and saves as a json, filepath is optional default is ./detailed_tfrs.json

TFR/Shape types

• TFRs have many types wether it be just a circle or a polygon or a TFR can have multiple circles/polygons, this scraper will parse each.
• Below is an example of each and the type of shapes the parser will return in the shapes list for each when the details are parsed

Simple Circle

• "points" represents only straight line points, can be used with "arcPoint" and "arcRadius" to create full shape
• "all_points" represents all points to create the entire polygon easily.

Poly Exclude

• Any shape, circle or poly that has parts that are excluded from TFR.
• Shape is returned as "all_points" only which represent one polygon excluding parts. !
