Abstract: A digital map based online platform is provided. The online platform comprises an outdoor map server, a data store, a building database, a space database, and a computer program stored in a medium. The data store manages digital files related to buildings including floor plans of buildings and digital files including website source codes related to spaces in individual folders for each building and space. The building database and the space database manage map setting data of buildings and spaces, respectively. The computer program stored in a medium executes a series of stages to integrally display an outdoor map, an indoor map including floor plans of buildings, Internet links, and responsive HTML pages on the view of a digital map. The medium includes a web server and a user terminal.

Abstract: A method is provided for integrally specifying a geographic location and an indoor location within a building. When the coordinates of one point on the Earth are given as a geodetic latitude ?, a longitude ?, and an ellipsoidal height h in a geodetic coordinate system based on the Earth ellipsoid, the location of the point is represented with a new coordinates including a Northing N, an Easting E, and selectively a floor representing integer F. The Northing N is given as a linear function of the distance measured along the prime meridian from the latitude-longitude origin to the waypoint, and the Easting is given as a linear function of the distance measured along the parallel of latitude from the waypoint to the ellipsoidal point.
