Latitude longitude in the wrong format DDDMM.MMMM 2832.3396N

Question

I have a gps module that gives me latitude in longitude in a weird format.

DDDMM.MMMM 

As written in the user manual, Degrees * 100 + Minutes.

As far as I know, these are degrees minutes seconds, and seconds between 0-59, higher than this will increase the minute. But it gives minutes in decimal places. Does this mean 1 / 1000th of a minute?

 eg. 07717.3644 E 077 --> degrees 17 --> minutes 3644 --> ? E --> Direction 

Just as I will convert it to decimal, I use the formula

 decimal = degrees + minutes/60 + seconds/3600. 

Answer 1

To convert this to decimal, we start by storing the DD part and simply divide MM.MMM by 60 to approve the MMM part of the decimal format.

 43. (48.225/60), -79.(59.074/60) 43.(0.80375), -79.(0.98456) 43.80375, -79.98456 

In your case

 eg. 07717.3644 E is the DDDMM.MMMM format 077 --> degrees 17 --> minutes .3644 --> minutes equals to sec/60 decimal = degrees + minutes/60 decimal = 77 + (17.3644 / 60) decimal = 77.28941

Answer 2

1 minute = 60 seconds, therefore 0.3644 minutes = 0.3644 * 60 = 21.86 seconds.

Answer 3

Value is not a number, but a string of degrees and minutes combined. You have to be careful because it is likely that latitude values ​​have only two degree digits (i.e. DDMM.MMMMM), so if you use string processing to separate values, you should consider this. However, both long and lat can be numerically processed as follows:

 double GpsEncodingToDegrees( char* gpsencoding ) { double a = strtod( gpsencoding, 0 ) ; double d = (int)a / 100 ; a -= d * 100 ; return d + (a / 60) ; } 

You can also pass the hemisphere symbol E / W or N / S to this function and use it to determine the corresponding + / - sign, if required.

Answer 4

Simple implementation in Python:

 latitude = <ddmm.mmmm> longitude = <dddmm.mmmmm> # Ricava i gradi della latitudine e longitudine lat_degree = int(latitude / 100); lng_degree = int(longitude / 100); # Ricava i minuti della latitudine e longitudine lat_mm_mmmm = latitude % 100 lng_mm_mmmmm = longitude % 100 # Converte il formato di rappresentazione converted_latitude = lat_degree + (lat_mm_mmmm / 60) converted_longitude = lng_degree + (lng_mm_mmmmm / 60) print converted_latitude, converted_longitude 

Replace breadth and logic.

Answer 5

Follow the algorithm to convert it.

 var t = "7523.7983" // (DDMM.MMMM) var g = "03412.9873" //(DDDMM.MMMM) function lat(t){ return (Number(t.slice(0,2)) + (Number(t.slice(2,9))/60)) } function lng(g) { return (Number(g.slice(0,3)) + (Number(g.slice(3,10))/60)) } console.log(lat(t)) console.log(lng(g))
