How do you convert Longitude/Latitude from DMS to DD?


Question 11.For this question you will convert Longitude/Latitude from Degrees Minutes Seconds (DMS) to Decimal Degrees (DD). DMS is a popular format to use for GPS units, but often computer mapping systems prefer having DD. Think about it like time. When you tell some one you will see themat 5:30, they understand 5 hours and 30 minutes. This is using two different units for a measurement of time. If you want to use just the unit of hour, then you would use decimal hours, and tell them that you will see them 5.5 hours. This was done by converting 30 minutes to half and hour by dividing the minutes by 60 because there are 60 minutes in an hour. You should do the same with converting DMS to DD. There are 60 minutes in a Degree and 3600 Seconds in a Degree. So to convert from DMS you will need to divide minutes by 60 and seconds by 3600 and add up all values. The formula is DD = D + M/60 + S/3600For this question you need to convert the following coordinates:Longitude = -9521’43” Latitude =2943’18” is the symbolfor degrees’ is the symbolfor minutes” is the symbol for seconds.Now convert these values, for Answer 1 put the Longitude in Decimal Degrees, and Answer 2 the Latitude.Question 21.If you type the long lat that you calcuated into Google Map the format of Lat, Long (e.g.29.721930, -95.362130), it will show you where in the world that long lat is. Once you find it in Google is your long lat located on TSU campus?TrueFalse

This article discusses the conversion of coordinates from the Degrees Minutes Seconds (DMS) format to Decimal Degrees (DD). DMS is commonly used by GPS devices, while DD is preferred by computer mapping systems. The difference between these two formats is like the difference between units of hours and minutes. Converting coordinates to DD will enable people to easily and accurately locate a point on a map while using computer mapping systems.

To convert coordinates from DMS to DD, one needs to make a few calculations using a specified formula. For example, given the coordinates Longitude = -9521’43” and Latitude = 2943’18”, one can convert them to DD by dividing minutes by 60 and seconds by 3600, and then adding up all values as per the formula DD = D + M/60 + S/3600. The result of the calculation for the Longitude is -95.3620, and the Latitude is 29.7283 in DD format. Once you have the coordinates in DD format, they can be accurately located on a map using computer mapping systems. In this regard, Google Maps provides a way to confirm if the converted coordinates correspond to a location on the map. By entering the longitude and latitude in the format of Lat and Long respectively, people can find the exact location of a point on the map. Finally, it is important to confirm that the calculated coordinates are accurate and correspond to the intended location. So, is the converted long lat located on TSU campus? We can answer this question by checking True or False in Google Maps.

– To convert Longitude/Latitude from Degrees Minutes Seconds (DMS) to Decimal Degrees (DD)
– To understand the process of converting DMS to DD
– To apply the knowledge of converting DMS to DD in a real-life scenario

Learning Outcomes:
By the end of this question, the learners will:
– Be able to convert DMS coordinates to DD coordinates
– Understand how to use the formula DD = D + M/60 + S/3600
– Be able to apply the knowledge of converting DMS to DD in practical situations
– Know how to check the location of a long lat using Google Maps

Conversion of Longitude and Latitude from DMS to DD

To convert from DMS to DD, follow the formula DD = D + M/60 + S/3600
D = Degrees
M = Minutes
S = Seconds

Answer 1: Longitude = -95.362
Answer 2: Latitude = 29.7219444

Using Google Maps to locate coordinates

To check the location of the long lat, type the coordinates in Google Maps in the format of Lat, Long. If the location of the long lat is on the TSU Campus, the answer is “True,” otherwise it is “False.”

Answer: The question does not provide the coordinates to determine if the long lat is located on the TSU Campus.

Solution 1: Converting Longitude from DMS to DD
Longitude = -95 degrees 21 minutes 43 seconds
DD = -95 + 21/60 + 43/3600
DD = -95.362

Solution 2: Converting Latitude from DMS to DD
Latitude = 29 degrees 43 minutes 18 seconds
DD = 29 + 43/60 + 18/3600
DD = 29.7217

Answer to Question 2:
This cannot be determined without knowing the actual coordinates of the long lat calculated in Solution 1 and 2.
