In the previous chapter, we prepared the TelZaViBA geodatabase and map document. We created the TelZaViBa Visual Studio project where we added the show tower range button. You also learned about the geodatabase and the feature classes, and some basic geometry operations. However, we only managed to show the range of the tower, and calculating the signal strength for a given point on the map is a different story. In this chapter, we will do some more geometrical operations on our towers to calculate the signal strength.
In this chapter, we will discuss the following topics:
Adding a point to the map
Finding the distance between two points
Finding and highlighting the closest tower
Displaying signal strength
