Euclidean Distance

Calculates, for each cell, the Euclidean distance to the closest source.

تحسب ، لكل خلية ، المسافة الإقليدية لأقرب مصدر.



1. Input raster or feature source data إدخال البيانات النقطية أو ميزة مصدر البيانات

The input source locations.

This is a raster or feature dataset that identifies the cells or locations to which the Euclidean distance for every output cell location is calculated.

For rasters, the input type can be integer or floating point.

مواقع مصدر الإدخال.

هذه مجموعة بيانات نقطية أو ميزة تحدد الخلايا أو المواقع التي يتم فيها حساب المسافة الإقليدية لكل موقع خلية إخراج.

بالنسبة إلى البيانات النقطية ، يمكن أن يكون نوع الإدخال عددًا صحيحًا أو نقطة عائمة.

Output distance raster

The output Euclidean distance raster.

The distance raster identifies, for each cell, the Euclidean distance to the closest source cell, set of source cells, or source location.

The output raster is of floating-point type.

Input barrier raster or feature class (optional)

The dataset that defines the barriers.

The barriers can be defined by an integer or a floating-point raster, or by a feature layer.

Maximum distance (optional)

The threshold that the accumulative distance values cannot exceed.

If an accumulative Euclidean distance value exceeds this value, the output value for the cell location will be NoData.

The default distance is to the edge of the output raster.

Output cell size (optional)

The cell size of the output raster that will be created.

This parameter can be defined by a numeric value or obtained from an existing raster dataset. If the cell size hasn't been explicitly specified as the parameter value, the environment cell size value will be used if specified; otherwise, additional rules will be used to calculate it from the other inputs. See the usage for more detail.

Distance method (optional)

Specifies whether to calculate the distance using a planar (flat earth) or a geodesic (ellipsoid) method.

Output direction raster (optional)

The output Euclidean direction raster.
