Analysts need to understand and visualize basic information about places and objects of interest, for instance, the distance between two geographic locations or the range of a weapon system. Using Distance and Direction in ArcMap, you can draw geodetic lines, circles, ellipses, and perform distance calculations based on time and rate. You can use created graphics for further analysis and planning by saving the graphics to feature classes, shapefiles, and files.
