6.3. GPS Collection Checklist, Field Form No 5. (Appendix A)
6.3.a. Card 1: Record wetland identification number (boxes 2-8), date (boxes 9-14), and observer (boxes 15-17) information.
6.3.b. GPS information will be collected using a Geoexplorer II (Trimble ®). GPS information collected in the field (rover data) will have to be differentially corrected. Base station information needed to differentially correct rover files will be purchased from servers near study wetlands. Operation of the GPS unit and subsequent differential corrections are not covered in this SOP; refer to the operator manual for details on use of equipment and differential corrections.
6.3.c. Collect GPS information on the wetland and catchment features listed below (a-i). GPS file names for each feature are listed below and consist of an alphanumeric 5-7 character code. The first characters of the file name will be coded information to describe the feature for which location information is being collected. The last three characters (numeric) are the unique number assigned to the wetland; that is the last three numbers of the wetland ID (Card 1, boxes 6-8). Collect the following GPS information for the following
6.4. Morphology Survey, Field Form No. 6 (Appendix A)
6.4.a. Card 1: Record wetland identification number (boxes 2-8), date (boxes 9-14), and observer (boxes 15-17) information.
6.4.b. Inspect the area and select an instrument location (laser level/total station) that will provide an unobstructed view of the entire basin. Proper location, in many cases, can reduce the need for turning points. The instrument location will be considered the benchmark. Drive a wooden stake (flush with the ground) that can be relocated to establish this as a temporary benchmark. Drive the stake flush with the ground and mark with a pin flag. This bench mark will be arbitrarily assigned an elevation datum of 100 ft (See Card 2, boxes 23-28). Collect an altimeter reading at this benchmark location and record on Card 1 (boxes 18-22)
6.4.c. Card 2: Record (boxes 29-34) the height of the instrument above the bench mark and calculate instrument HT (boxes 35-41). This will be instrument height A. If a turning point is needed during the survey, additional space has been provided on Card 2 for the calculation of an instrument height B (i.e., Instrument height B, boxes 61-67).
6.4.d. Card 3: Record instrument height (A or B) and rod readings for the following:
6.4.e. Card 4: Quadrat locations will be marked by the vegetation crew with PVC-pipe labeled with the transect number (1-4) and quadrat number (1-#). For each transect/quadrat record the transect number (box 24, a-u), quadrat number (box 26, a-u), instrument height (box 27, a-u), and rod reading (boxes 28-33, a-u).
6.4.f. Card 5: Water control structures include stand pipes, culverts, and spillways. For each water control structure, record instrument height (box 26, a-c) and rod reading (boxes 27-32, a-c). Rod readings are to be collected at the lowest overflow elevation. For multiple water control structures, describe in detail the type of water control structure on the line next to the rod reading. Water control structure codes used for the elevation survey (i.e., 1WC, 2WC, 3WC) are the same as that used for the GPS survey to allow location and elevation of each water control structure to be linked. Thus, the GPS file name and elevation file name for each water control structure must be the same.
6.4.g. Card 6: For each dam, record instrument height (box 26, a-c) and rod reading (boxes 27-32, a-c). Collect rod reading at the mid-point along the linear length of the dam. For multiple dams, describe in detail each dam on the line next to the rod reading. Dam codes used for the elevation survey (i.e., 1DA, 2DA, 3DA) are the same as used for the GPS survey; location and elevation of each dam must be linked. Thus, the GPS file name and elevation file name for each dam must be the same.
6.4.h. Card 7: This category is for any additional elevation information that may be collected. For other features for which elevation information is collected, record the instrument height (box 26, a-h) and rod reading (boxes 27-32, a-h). Describe in detail these features on the line next to rod-reading line. If GPS information was collected for this feature, use the same file name.
