Feb 3, 2015 · I'm trying to create a point on each corner of the polygon. I've used a geoprocessing tool called "Feature Vertices to Points" in ArcGIS, but what it does is create a point for each vertice: Is there a tool out there that will allow for the creation of corner points?

A polygon is a planeshape (two-dimensional) with straight sides. Examples include triangles, quadrilaterals, pentagons, hexagons and so on.
So what can we know about regular polygons? First of all, we can work out angles. All the Exterior Angles of a polygon add up to 360°, so: Each exterior angle must be 360°/n (where nis the number of sides) Press play button to see. Interior Angle = 180° − Exterior Angle We know theExterior angle = 360°/n, so: Interior Angle = 180° − 360°/n And now ...
Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: The "outside" circle is called a circumcircle, and it connects all vertices (corner points) of the polygon. The radius of the circumcircle is also the radiusof the polygon. The...
We can learn a lot about regular polygons by breaking them into triangles like this: Notice that: 1. the "base" of the triangle is one side of the polygon. 2. the "height" of the triangle is the "Apothem" of the polygon Now, the area of a triangleis half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2 To ...
By cutting the triangle in half we get this: (Note: The angles are in radians, not degrees) The small triangle is right-angled and so we can use sine, cosine and tangent to find how the side, radius, apothem and n(number of sides) are related: There are a lot more relationships like those (most of them just "re-arrangements"), but those will do for...
We can use that to calculate the area when we only know the Apothem: And there are 2 such triangles per side, or 2n for the whole polygon: Area of Polygon = n × Apothem2 × tan(π/n) When we don't know the Apothem, we can use the same formula but re-worked for Radius or for Side: Area of Polygon = ½ × n × Radius2 × sin(2 × π/n) Area of Polygon = ¼ × ...
And here is a table of Side, Apothem and Area compared to a Radius of "1", using the formulas we have worked out:
And here is a graph of the table above, but with number of sides ("n") from 3 to 30. Notice that as "n" gets bigger, the Apothem is tending towards 1 (equal to the Radius) and that the Area is tending towards π= 3.14159..., just like a circle. What is the Side length tending towards?
They have a number of corner points connected by straight lines lying on the boundary of the polygon. The corner points are called vertices, and the boundary line segments are called edges. Let's think about this with an example. Example 4.1. Consider the points v1 = (0; 0), v2 = (1; 0), v3 = (0; 1), and v4 = (1; 1).
Sep 15, 2022 · This article provides two methods to generate point features based on the corner vertices of polygon features using the Feature Vertices To Points tool or the Coordinate Conversion function. In this example, there are four polygon features and the corner vertices of one of the polygon features are displayed in the image below.
Jan 29, 2011 · The bottom left corner is the point located below and to the left of the intersection point. Analog conditions hold for the other three corners. If you don't know the order of the points in advance, you don't know opposite corners, hence the diagonals.
