ClusterSeer can import data in planar (projected) or geographic coordinates. If you perform a focused cluster detection method on your data, specify the location of the focus in the data's original coordinates (i.e. planar coordinates for planar data, geographic coordinates for geographic data).
Planar. This category encompasses all map projections including UTM (Universal Transverse Mercator) and user-coordinates.
Geographic (latitude-longitude). Within ClusterSeer, data in geographic coordinates are transformed to UTM for calculation and mapping.
If your data are in geographic coordinates, you can choose to use a scale of either meters or kilometers. This scale will be used to specify distances on the map and in the analyses.
