resolution

The minimum distance that separates unique x,y coordinate values when stored in an ArcGISFeatureTable. The resolution represents the detail in which a feature class records the location and shape of features, defining the number of decimal places stored. It is the minimum distance that separates x,y coordinate values in the Geometry of an ArcGISFeature. Any coordinates that differ by less than the resolution will be stored as the same coordinate value. The units of SpatialReference.resolution are the units of the horizontal coordinate system (SpatialReference.unit) defined when this spatial reference was created.

A separate resolution, SpatialReference.verticalResolution, is defined for the distance between z-values.

Spatial references have default precision properties, and Esri strongly recommends using the default values in most cases. However some high-accuracy workflows customize the default values to preserve their data with higher precision. To store coordinates using a non-default resolution, create a new dataset that uses a custom resolution spatial reference - for example by setting TableDescription.spatialReference when creating a new geodatabase table. See SpatialReferenceBuilder for more information about creating spatial references with custom precision values.
