The image is of a globe with lines on it. There are five lines on the inside of the globe but they are not straight lines. The only straight line is the one down the center. The other lines curve with the outside of the circle. All of the lines are vertical.
This is a Longitude icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
