How to get E6 format of Longitude Latitude for Google Maps on Android
how do i find out the SPECIFIC E6 values of longitude latitude of a location. For example, i googled for long-lat of Asuncion, the capital city of Paraguay. It returns me:
The latitude and longitude of Asuncion, Paraguay is 25°16' S, 57°40 W
Now how do i convert THIS format of long-lat into E6 format of long-lat which android understands? What exactly IS THIS E6 thing?
[p.s. i also googled for E6 long-lat of Asuncion....... with no luck]
So it's a two step process - thanks to hooked82's answer
step 1. Conversion from DMS to Decimal Degrees From Wikipedia
Given a DMS (Degrees, Minutes, Seconds) coordinate such as 87°43′41″ W, it's trivial to convert it to a number of decimal degrees using the following methods:
Lat. North = + Lat. South = - Long. East = + Long. West = -
step 2. Conversion from Decimal Degrees to MicroDegrees (the E6 format) From SO discussion
MicroDegrees (the E6 format) = DecimalDegrees * 1e6 --- as mentioned in AndroidDevGuide as well
float lat = -23.4456f; //in DecimalDegrees float lng = 45.44334f; //in DecimalDegrees GeoPoint gp = new GeoPoint((int)(lat * 1E6), (int)(lng * 1E6));
I'm not sure of a programmatic approach to converting a DMS Coordinate to Microdegrees, but there is a manual conversion process which I came across at:
Also, take a look at this SO question:
If you're manually trying to get GPS coordinates and want values that Android can handle, you can always go to Google Maps and Right-Click on a point on the map and select "What's Here". It will give you the lat/long of that position, though there are many ways of getting these.
