Predict Using Trend function

Available with Image Analyst license.

Overview

Computes a forecasted multidimensional raster layer using the output trend raster from the Generate Trend function or Generate Trend Raster geoprocessing tool.

Notes

The format of the time, depth, and height values must match the format of the dimension values used to generate the trend raster. If the trend raster was generated for the StdTime dimension, the format should be YYYY-MM-DDTHH:MM:SS, for example, 2050-01-01T00:00:00. UNIX Epoch Time and Posix Time are also common designations for time. Multiple values are separated with a semicolon.

Parameters

Parameters	Description
Raster	The input multidimensional trend raster from the Generate Trend function.
Dimension Definition	Specifies the method used to provide prediction dimension values. By Value—The prediction will be calculated for a single dimension value . For example, you want to predict yearly precipitation for the years 2050, 2100, and 2150. This is the default. By Interval—The prediction will be calculated for an interval of the dimension defined by a start and an end value. For example, you want to predict yearly precipitation for every year between 2050 and 2150.
Values	The dimension value or values to be used in the prediction. The format of the time, depth, and height values must match the format of the dimension values used to generate the trend raster. If the trend raster was generated for the StdTime dimension, the format should be YYYY-MM-DDTHH:MM:SS, for example, 2050-01-01T00:00:00. Multiple values are separated with a semicolon.
Start	The start date, height, or depth of the dimension interval to be used in the prediction. This parameter is required when the Dimension Definition parameter is set to By Interval.
End	The end date, height, or depth of the dimension interval to be used in the prediction. This parameter is required when the Dimension Definition parameter is set to By Interval.
Value Interval	The number of steps between two dimension values to be included in the prediction. The default value is 1. This parameter is required when the Dimension Definition parameter is set to By Interval.
Unit	The unit that will be used for the value interval. This parameter only applies when the dimension of analysis is a time dimension. Hours—The prediction will be calculated for each hour in the range of time described by the Start, End, and Value Interval parameters. Days—The prediction will be calculated for each day in the range of time described by the Start, End, and Value Interval parameters. Weeks—The prediction will be calculated for each week in the range of time described by the Start, End, and Value Interval parameters. Months—The prediction will be calculated for each month in the range of time described by the Start, End, and Value Interval parameters. Years—The prediction will be calculated for each year in the range of time described by the Start, End, and Value Interval parameters.
