You can calculate up to nine different magnetic component types into nine or more existing fields. You must specify a magnetic component and an existing field to write to. Magnetic Component Field(s) ( magnetic_component_fields for Python) control the type of magnetic field calculation. If you need to add a field, use the Add Field tool. Magnetic field values are written to existing fields. In this configuration, the tool runs once per input point.
The iterator can pass a value into the Altitude parameter. To use a different altitude value for each input point, use a Feature Selection or Field Value iterator in ModelBuilder. Do not use decimal degrees or unknown units for Altitude.Īltitude applies the same elevation value to all points in Input Features ( in_features for Python). To express this value in Python, use a combination of the unit value and type, enclosed in quotation marks ( "3 meters"). Altitude must be a numeric value above sea level. You can filter input points by applying a layer definition query or selection set.Īltitude specifies the elevation as a linear unit of the input points. Input Features ( in_features) must be points. For example, if the date specified is 2012, then the model epoch for 2010–2014 will be used. This tool uses the model epoch specific to the date provided.
