Feature Layer
Extent
(可选)

Custom bounding units for the grid extent. Enter the Y minimum and maximum and the X minimum and maximum.

Envelope
BDSFeatureClass
(可选)

Input feature class that will contain the available layers that can be appended to the output feature class (grid).

Feature Layer
GridSymbolizationField
(可选)

Defines the variable that will be thematically mapped in the output feature class.

String
SelectedSummarizations
[SelectedSummarizations,...]
(可选)

Allows you to select from an available list of variables in the Layer to Aggregate input feature class to append to the output feature class.

String
UseOnlineData
(可选)
