How do I calculate the distance between the certain of a polygon (in this case, centre of a district), to the closest point on a map (in this case, the points are road entries)?
I haven't tried anything yet. I know how to find the centre of a polygon, and I know how to calculate distances. But I do not know how to combine the two.
You would use the Near GP tool which:
Calculates distance and additional proximity information between the input features and the closest feature in another layer or feature class.
If you would like to calculate the distance from the centroid of every polygon (there are many variations on how a centroid could be defined - center of gravity or geometric center), you would need to create first those points (either using Feature To Point or other methods such as using Calculate Geometry).
