Measuring Elevation Differences With A Transit

The following measuring equipment will be needed: transit, and tripod, metric measuring rod, logbook and pencil. The instruments are setup to measure the difference in elevation between two points as shown in figure 5. The rod measures the vertical distance between the transit levels line of site and the selected point. Make sure the rod is held plumb or an error will occur.
