arcgis desktop - Find point on line with given nearest point

I have a line and point layer. Points are not exactly intersect with line layer. With respect to existing point, how to find the new points which are exactly on the line ? consider buffer distance is provided.

Answer

You can use the near tool to calculate the perpendicular points on a line :

1. 
   

   Calculate the distance from points to lines with the Near tool :

   
   
   
   
   • input features: Points
   
   
   • near features: Lines
   
   
   • check "location option" to get near_x and near_y
   
   
   
   



2. 
   

   Calculate an event layer from near_x and near_y

   
   

This gives a new point layer with the same id's as the input points, all laying on the line object. You can then use a select between to filter the distance, if you like.
