Thank you for your help. The route that I created is a line polyline that has measurements along the route, not a network of intersecting routes.
What I did was that I selected the polyline I wanted to create a route and used the Create Route tool. Then, I projected both the polyline and the points feature from GCS North America 1983 into a projected coordinate system, NAD 1983 UTM 10N. Afterward, I created a database event table using the excel table I created for the measurements along the route. After I created the route, I used the Make Route Event Layer tool to perform the dynamic segmentation on the route I needed. Finally, I used the Locating Feature Along a Route to locate the points relative to the dynamic segmented route. After performing a quality check on the output attribute table created by the locating features along a route tool, I realized that the latitude and longitude has been changed from the original point feature attribute and the measurements along the route was also incorrect.
One of the problems I had while performing the dynamic segmentation was not being able to flip the dynamic segmentation starting point to the opposite end of the route. Therefore, I relabel the description of the measurements to display the right measurements, which is basically just flipping the measurements. I do not think this is the cause for the modified latitude and longitude, but it may be another cause for the incorrect measurement.
Can you elaborate on this statement: "As far as I know the tool itself should not directly alter those attributes, but it will alter the actual location of the point if those attributes are recalculated based on the event layer position using the geometry calculator."?
Thank you for your help.
