Generate Range Rings From Lookup Table (Defense Tools)

Summary

Creates a set of concentric circles from a center based on values stored in a lookup table.

Legacy:

This is a deprecated tool. This functionality has been replaced by the Generate Range Rings From Features tool.

Usage

• The Range Ring Type parameter is used to determine whether rings will be created from an interval and number of rings or a minimum and maximum distance. These two range ring types are described as follows:

  • Generating range rings from an interval means you will specify the number of rings to create. The first ring will be a distance from the center point that you specify and each subsequent ring will be created that same distance from the previous ring.

  • Generating range rings from a minimum and maximum distance means you will specify two values, a minimum and maximum. One ring will be created for each value at the specified distance from the center.

• Range ring values, either interval or minimum and maximum distance, must be stored in a table as follows:

  • The table used to create range rings from an interval must contain a minimum of one row with the following three fields:

    • A text field containing a lookup name that will be used to choose the row containing the values for the interval and the number of rings to be created. The default field name is Name.

    • A long, short, double, or float field containing a value for the interval at which rings will be created. The default field name is Intervals.

    • A long, short, or integer field containing a value for the number of rings to be created. The default field name is Rings.

  • The table used to create range rings from minimum and maximum distances must contain a minimum of one row with the following three fields:

    • A text field containing a lookup name that will be used to choose the row containing the values for the minimum and maximum distances at which rings will be created. The default field name is Name.

    • A long, short, double, or float field containing a value for the minimum distance at which a ring will be created. The default field name is Min.

    • A long, short, double, or float field containing a value for the maximum distance at which a ring will be created. The default field name is Max.

Parameters

Label	Explanation	Data type
Input Features (Center Points)	The point feature set that identifies the center of the range ring. The input must have at least one point.	Feature Set
Input Lookup Table	The input table that contains values for creating rings.	Table
Output Feature Class (Rings)	The output feature class containing the ring features.	Feature Class
Selected Name	The row from the Input Lookup Table that contains the input values for minimum and maximum values or number of rings and interval.	String
Range Ring Type	Specifies the method used to create the range rings. Interval—Range rings will be generated based on the number of rings and distance between rings. This the default. Minimum and maximum—Range rings will be generated based on a minimum and maximum distance.	String
Output Feature Class (Radials) (Optional)	The feature class containing the output radial features.	Feature Class
Number of Radials (Optional)	The number of radials to create.	Long
Distance Units (Optional)	Specifies the linear unit of measurement for the Ring Interval Field parameter or the Input Table Minimum Range and Input Table Maximum Range parameters. Meters—The unit will be meters. This is the default. Kilometers—The unit will be kilometers. Miles—The unit will be miles. Nautical miles—The unit will be nautical miles. Feet—The unit will be feet. US survey feet—The unit will be U.S. survey feet.	String
Input Table Selected Name Field (Optional)	The field from the input table that contains the Selected Name value. The default field name is Name.	Field
Input Table Minimum Range (Optional)	The field from the input table that contains the minimum range value. The default field name is Min.	Field
Input Table Maximum Range (Optional)	The field from the input table that contains the maximum range value. The default field name is Max.	Field
Number of Rings Field (Optional)	The field from the input table that contains the number of rings value. The default field name is Rings.	Field
Ring Interval Field (Optional)	The field from the input table that contains the ring interval value. The default field name is Interval.	Field
