GA Layer To Contour (Geostatisical Analyst)
Récapitulatif
Creates a feature class of coutours from a geostatiscal analysis layer. The output feature class can be either a line feature class of contour lines or a polygon feature class of filled contours.
Utilisation
For data formats that support Null values, such as file and personal geodatabase feature classes, a Null value will be used to indicate that a prediction could not be made for that location or that the value should be ignored when used as input. For data formats that do not support Null values, such as shapefiles, the value of -1.7976931348623158e+308 is used (this is the negative of the C++ defined constant DBL_MAX) to indicate that a prediction could not be made for that location.
