Proposing a New Validation Rule for Longitude, Latitude, and Street View Camera Angle

[asfiaaiman]

I propose adding a new custom validation rule to Laravel that will handle validation for longitude, latitude, and Street View camera angle values. This rule will also account for optional degree signs (°) that might be included with these values.

1. Longitude Validation:

Criteria: Should be within -180 to 180 degrees.
Example Valid Inputs: -73.935242, 45.0, 180°
Example Invalid Inputs: -181, 200, abc

2. Latitude Validation:

Criteria: Should be within -90 to 90 degrees.
Example Valid Inputs: 40.712776, -34.052235, 90°
Example Invalid Inputs: -91, 100, xyz

3. Street View Camera Angle Validation:

Criteria: Should be between 0 and 360 degrees.
Example Valid Inputs: 0, 180.5, 360°
Example Invalid Inputs: -10, 400, angle

Nice idea

1. + 2. Keep in mind, that there could be different notations, so it might not be a good idea to favor one above the other:

• ISO 6709/D in degrees (e.g. 1.286795, 103.854511)
• ISO 6709/F in decimal and CRS (e.g. 50°40'46"N 95°48'26"W 123.45m)
• [ lat, lng ] tuple
• { lat: int, lng: int } object
• etc.
  If it's merely about validating numbers, a custom rule might suffice (also, \Illuminate\Validation\Rule is macroable 😉)

3. "Street View Camera Angle" seems oddly specific—in other word: proprietary validation rules are probably not wanted and it's recommended to create a package for that. However, "angle" might be fine
