pointGridsInPolygons

Generates uniform (regularly spaced) points located in the polygons of the input polygon dataset. The distance between the points for each polygon can be the same or different - based on the values in a numeric field of the input polygon feature class. The user can specify the rotation angle for the resulting point grid.

Inputs:

A polygon feature class
The distance between the points for each polygon can be input in one of the following ways
- A numeric field which values will be used to get the distance between points for each polygon.
- A constant number defining the distance between points for all polygons.
Rotation angle
- Constant for all polygons - (in degrees starting from East anti-clockwise)
- From field - different rotation angle for each field (in degrees starting from East anti-clockwise)
- Along the longest axis of each polygon
- Along the longest side of each polygon

Outputs:

New Point feature class.
The following fields are added to the attribute table of the resulting feature class.
- [ET_ID] - the ID of the original polygon

Illustration:

Distance between points = 10, Rotational angle = 0

pointGrid1

Original polygons labeled with the values in field to be used as a source for getting the distance between the points.
Rotational angle = "Along the longest Side"

Command line syntax

ET_GPPointGridsInPolygons<input_dataset> <out_feature_class> {distance} {distance_field} {angle_from} {rotation_angle} {angle_field}

Parameters

Expression	Explanation
<input_dataset>	A Polygon feature class or feature layer
<out_feature_class>	A String - the full name of the output feature class.
{distance}	A Double representing the distance between the points for all polygons
{distance_field}	A String representing the name of a numeric field which values will be used to get the distance between the points for each polygon
{angle_from}	A String defining how the rotation angle will be specified "Constant" - Constant for all polygons - (in degrees starting from East anti-clockwise) "From field" - different rotation angle for each field (in degrees starting from East anti-clockwise) "Longest Axis" - Along the longest axis of each polygon "Longest Side" - Along the longest side of each polygon
{rotation_angle}	A Double - specifying the rotation angle for all polygons.
{angle_field}	A String - the name of the field to be used as source for rotation angle.
