Calculate Metrics (Topographic Production Tools)

サマリー

Populates metrics for features in a geodatabase. Metrics include length, width, area, and elevation attributes.

使用法

注意:

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

  • The following are supported feature attribute metrics:

    • Length—The default attributes are LEG, LEN, LEN_, LGN, and LZN.

    • Width—The default attributes are WID, WID_, and WGP.

    • Area—The default attributes are ARA, ARE, and ARE_.

    • Angle of orientation—The default attributes are AOO, DOF, and FEO.

    • Elevation—The default attributes are ZV2 and ZVH (must be z-enabled data).

      注意:

      Elevation metrics that the tool derives from a raster file specified for the Elevation Raster parameter value will overwrite existing elevation data.

    • Military Grid Reference System—The default attributes are MGRSValue and MGRS.

  • Input metric types are processed based on the geometry of the feature class as follows:

    • Points—Elevation

    • Lines—Length and Elevation

    • Polygons—Length, Width, Area, Angle of Orientation, and Elevation

  • The Input Length Attributes, Input Width Attributes, Input Area Attributes, Input Angle of Orientation Attributes, and Input Elevation Attributes parameter values reference a comma-delimited list of field names in the data model. If one or more fields exist in the Input Features parameter value, the field will be calculated according to the metrics specified for the Input Metric Types parameter value.

  • You can add custom field names to the list of options in the Input Length Attributes, Input Width Attributes, Input Area Attributes, Input Angle of Orientation Attributes, and Input Elevation Attributes parameter values. This tool will attempt to compute metrics in a custom field.

  • This tool can calculate the Military Grid Reference System (MGRS) coordinates for features using the standard precision formats as well as the format used for Image City Map (ICM) annotation features. For ICM format, the value is a combination of the column and row number in which the feature is located.

    ライセンス:

    The ArcGIS Spatial Analyst extension allows this tool to rotate features such as springs and natural pools to face downhill. The ArcGIS Topographic Mapping product data files include certain point feature layers with a CBO_Rotation attribute field that is set up to be updated by this tool using the Elevation Raster parameter value and specifying Angle of orientation for the Input Metric Types parameter value.

String

Input Width Attributes

(オプション)

A comma-delimited string of field names from which the width metrics will be calculated. The default is WID,WID_,WGP. You can add the names of other width metric fields; if the fields exist in the Input Features value, they will be computed.

String

Input Area Attributes

(オプション)

A comma-delimited string of field names from which the area metrics will be calculated. The default is ARA,ARE,ARE_. You can add the names of other area metric fields; if the fields exist in the Input Features value, they will be computed.

String

Input Angle of Orientation Attributes

(オプション)

A comma-delimited string of field names from which the angle of orientation metrics will be calculated. The default is AOO,DOF,FEO. You can add the names of other angle of orientation metric fields; if the fields exist in the Input Features value, they will be computed.

String

Input Elevation Attributes

(オプション)

A comma-delimited string of field names from which the elevation metrics will be calculated. The default is ZV2,ZVH. You can add the names of other elevation metric fields; if the fields exist in the Input Features value, they will be computed.

String

Input Floating Point Precision

(オプション)

The precision of the metrics written to the target attributes.

Long

Input MGRS Attributes

(オプション)

A comma-delimited string of field names from which the MGRS coordinates will be calculated. The default is MGRSValue,MGRS. You can add the names of other MGRS fields; if the fields exist in the Input Features value, they will be computed. The fields must have a String field type and a field length greater than the largest possible MGRS coordinate value.

String

MGRS Precision

(オプション)

Specifies the precision of the coordinates that will be calculated for the target attributes.

  • 6×8 (4Q)—The precision will be calculated at grid-level precision, typically the polygon formed by a 6-degree wide UTM zone and 8-degree high latitude bands.

  • 100km (4QFJ)—The precision will be calculated at 100,000 meters squared.

  • 10km (4QFJ16)—The precision will be calculated at 10,000 meters squared.

  • 1km (4QFJ1267)—The precision will be calculated at 1,000 meters squared.

  • 100m (4QFJ123678)—The precision will be calculated at 100 meters squared.

  • 10m (4QFJ12346789)—The precision will be calculated at 10 meters squared.

  • 1m (4QFJ1234567890)—The precision will be calculated at 1 meter squared.

  • Image City Map (1234)—The precision will be calculated at the level of an Image City Map (ICM). This is the default.

String

Elevation Raster

(オプション)

The raster file from which the elevation metrics will be derived. Elevation metrics derived from a raster file specified here will overwrite existing elevation data.
