摘要
Location-Based Services (LBS) stands for the provision of information about the position of a device or a user often offered as a service via various means of media. Haversine formula is the method used to calculate the distance from two different points. In this research, Haversine method applied on calculating the distance for presence system based on the distance of location. This system allows users in presenting using mobile applications in addition to facilitate the presenting of data preservation. Use of LBS technology to detect users in an area of allowable locations. This detection is done by looking at the closest point from the predetermined center point. Center point will store the coordinates and radius of the presence area. This research develops Haversine method for measurement and estimation of distance with limitation in localization. Implementation model includes signal measurements with wifi position and GPS values to identify the precise location for human presence system.
