1. According to MDOT SHA, what is the preferred coordinate system
for submitting GPS data?
A. NAD83 Feet HARN, Maryland State Plane
B. WGS84, Latitude and Longitude
C. NAD27, Maryland State Plane
D. ITRF, UTM Zone 18N
Answer: A. NAD83 Feet HARN, Maryland State Plane Explanation: The
Maryland State Highway Administration (SHA) prefers GPS data in the
format of X, Y coordinates in the Maryland State Plane, NAD83 Feet HARN,
as it most easily integrates with their workflow .

counting devices?
A. 1-meter accuracy or better
B. 3-meter accuracy or better
C. 1-centimeter accuracy or better
D. 10-meter accuracy or better
Answer: B. 3-meter accuracy or better Explanation: SHA prefers sub-
meter accuracy; however, 3-meter accuracy is also acceptable for this
specific application .
,3. Which type of control point material is specified for a "B" Traverse
classification?
A. Only cast-in-place concrete monuments
B. 36-inch rebars with metal caps
C. Wooden hubs and tacks only
D. 18-inch rebars with caps or railroad spikes with punches
Answer: D. 18-inch rebars with caps or railroad spikes with
punches Explanation: For "B" Traverse classification, acceptable materials
