Create JOG Elevation Tint Bands from features (Defense Mapping)
Summary
Converts contour polylines into elevation tint band polygon features. The features can be used to represent different elevation levels on a Joint Operations Graphic (JOG).
Usage
-
It is recommended that you use contour lines that have been collected using meters.
The feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters must all contain the field listed in the Contour Elevation Field parameter.
The Elevation Units parameter value applies to all the feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters.
Syntax
| Parameter | Explanation | Data Type |
AOI_Feature_Class (Optional) |
The area of interest for the JOG. This feature is typically stored in an index feature class. | Feature Layer |
Contour_Feature_Class |
The feature layer that contains the contours. The information for the output bands will be derived from these features. This must be a polyline feature class. | Feature Layer |
Contour_Elevation_Field |
The field in the contour feature layer from which the elevation values will be derived. | Field |
Contour_Elevation_Units | The unit of measurement that has been used to collect the contours and exclusion features.
| String |
Output_Feature_Class |
The feature class that will contain the banding features. | Feature Class |
Output_Feature_Class_Units |
Output band distance units.
| String |
Exclusion_Feature_Classes [Exclusion_Feature_Classes,...] (Optional) |
Feature layers that define areas for processing exclusion. Excluded areas will not be taken into account when calculating the percent area ratio for the output bands. | Feature Layer |
Code Sample
This stand-alone Python script generates elevation tint bands for a TLM feature.
