Polygon Vertex Coordinates in ArcGIS | Feature Vertices to Points | Add Geometry Attributes
Here’s a step-by-step procedure to extract and export the coordinates of polygon vertices using Feature Vertices to Points and Add Geometry Attributes in ArcGIS:
Step 1: Open ArcGIS and Load Your Polygon Layer
• Launch ArcGIS and open your project.
• Add your polygon feature layer to the map (if it’s not already loaded).
Step 2: Use the "Feature Vertices to Points" Tool
1. Open the Geoprocessing pane:
o Go to the Analysis tab.
o Click on Tools to open the Geoprocessing pane.
2. Search for the "Feature Vertices to Points" tool:
o In the Geoprocessing pane, type "Feature Vertices to Points" in the search bar.
o Select the tool from the search results.
3. Set the parameters for the tool:
o Input Features: Choose your polygon layer.
o Point Type: Select "All" to create a point for each vertex of the polygon.
o Output Feature Class: Specify a name and location for the output point layer.
4. Run the tool:
o Click Run to generate a new point layer where each vertex of your polygon is represented as a point.
Step 3: Add XY Coordinates to the Vertices
1. Search for the "Add Geometry Attributes" tool:
o In the same Geoprocessing pane, search for "Add Geometry Attributes".
o Select the tool from the search results.
2. Set the parameters for the tool:
o Input Features: Select the point layer created in Step 2 (from the Feature Vertices to Points tool).
o Geometry Properties: Select "POINT_X" and "POINT_Y" to add the X (longitude) and Y (latitude) coordinates of the points.
o The tool will add new fields (POINT_X and POINT_Y) to the attribute table of the point layer.
3. Run the tool:
o Click Run to apply the changes.
Step 4: View the Coordinates in the Attribute Table
1. Open the attribute table:
o Right-click on your point layer in the Contents pane.
o Select "Attribute Table" to open the table.
2. Verify the coordinates:
o In the attribute table, you’ll see new fields labeled POINT_X (longitude) and POINT_Y (latitude).
o These fields contain the coordinates of each vertex.
Step 5: Export the Coordinates
1. Open the export options:
o At the bottom-right of the attribute table, click the Options button (three horizontal lines).
2. Select "Export":
o Choose "Export" from the dropdown menu.
3. Export format:
o In the Export dialog, choose a file format such as CSV or Excel.
o Specify the file location and name.
4. Export:
o Click OK to export the table with the vertex coordinates.
Step 6: Use the Exported Coordinates
• You now have the exported file containing the vertex coordinates, which can be included in reports, further analysis, or other documentation.
