Tagging multiple geolocation on different places of an image Is it possible to tag multiple geolocation (logitude, latitude) on different places of an image? So basically I am having an image of top view of my college building and I want to tag each room with its longitude and latitude and also tag corridors with their longitude and latitude so that when a user moves around the college I can get their phones geoloaction and tag their location on that image. Not able to do this with a map because map doesn't show rooms of the college building so I am planning to make a 2d/3d image and to tag location on it.

Transforming Coordinates from EASE-Grid to Lat/Lon in R I have 3 matrices, all 721x721. The first contains global snow cover data in the NSIDC's EASE-Grid, the second is the latitude corresponding to each cell of the EASE-Grid and the third is the longitude corresponding to each cell of the EASE-Grid. For example, the latitude of the snow data in cell [x,y] is given in cell [x,y] of the latitude matrix. I want to transform the coordinate system from the EASE-Grid into the regular Lat/Lon grid given in the latter two matrices, essentially reordering all the cells in the snow data matrix based on the latitude and longitude matrices. Any ideas how to do this?
