tool in toolbox to find a two point in perimeter of a polygon according to distance in arcmap

To find two points on the perimeter of a polygon based on a specified distance in ArcMap, you can follow these steps: ### Step 1: Prepare your Data 1. **Load your Polygon Layer**: Open ArcMap and add the polygon layer you'd like to analyze. ### Step 2: Create a New Feature Class (Optional) If you want to save the results, it’s a good idea to create a new feature class to store your points. ### Step 3: Use the 'Feature Vertices To Points' Tool 1. **Find the Tool**: Go to `ArcToolbox` -> `Data Management Tools` -> `Features` -> `Feature Vertices To Points`. 2. **Input your Polygon Layer**: Select your polygon layer as the input. 3. **Choose Output Type**: Select "ALL" to get all vertices as points, or "BOTH_ENDS" if you only want the end vertices. 4. **Run the Tool**: This will generate a point feature class with all vertices of your polygon. ### Step 4: Use the 'Point Distance' Tool (Optional) If you have a specific target distance, you can calculate distances between points using the `Point Distance` tool in ArcToolbox, which can be found under: - `Analysis Tools` -> `Proximity` -> `Point Distance`. ### Step 5: Using the 'Generate Near Table' Tool 1. **Find the Tool**: Go to `ArcToolbox` -> `Analysis Tools` -> `Proximity` -> `Generate Near Table`. 2. **Set Parameters**: - Set `Input Features` as the point feature class created from the polygon vertices. - Set `Near Features` as the same point feature class or another layer of points if needed. - Specify a search radius if required. 3. **Run the Tool**: This will generate a table showing distances between the points. ### Step 6: Query and Select Points 1. **Use Select By Attributes**: You can access the generated table and find pairs of points that meet your specific distance criteria. - For example, you can use SQL queries to filter pairs within a certain distance. ### Step 7: Create Points on the Polygon Perimeter If you have specific distance values: 1. Manually extract or create points along the polygon perimeter at your desired distances. 2. You can use the `Construct Points` tool or manually map points based on your distance measurement. ### Step 8: Save the Results 1. If you’ve created a new feature class or point layer, don’t forget to save your results accordingly. ### Additional Tips: - You may want to visually inspect your results for accuracy. - If numerous polygons or large datasets are involved, scripting through ModelBuilder or Python scripting can be helpful for consistency and automation. These steps should guide you in finding two points along the perimeter of a polygon by a specified distance using ArcMap.
