Everything you need to know about the new Share your Location feature on your profile page :

Location-privacy :

Advantages of sharing your location : * helps the community to know where you live approximately . * helps you to find and learn about projects near you (feature which we will be working in near future) .

Here are some things you might want to know :

1.) The location:blurred tag : * This tag on your profile page enables blurring , which truncates the latitude and longitude coordinates . For example :

2.) The blurred:true tag : * This tag removes the marker from your map , giving the viewers of your profile only a vague idea about your location .

3.) What is zoom level ? * Lower zoom levels means that the map shows entire continents, while higher zoom levels means that the map can show details of a city.

  • When we represent the world at zoom level zero, it’s 256 pixels wide and high. When we go into zoom level one, it doubles its width and height, and can be represented by four 256-pixel-by-256-pixel images .

  • At each zoom level, each tile is divided in four, and its size doubles, quadrupling the area.
