Since 2012.02. Optional maximum horizontal snap distance in meters. When the parser provides horizontal location coordinates (x,y) and no locationIds, then the location mapping will be done by matching the horizontal coordinates. The horizontal snap distance is the tolerance used to detect which internal and external horizontal coordinates are the same. Don't forget to configure the geoDatum when the input format does not provide the coordinate system for the locations. When the parser does not provide the coordinates for a time series an error is logged. Note: this option has no effect for grid data. Note 2: it is not possible to import data using horizontal coordinates and using locationIds in the same import, need to define separate import elements for that (one with maximumSnapDistance and one without maximumSnapDistance).
