Why was the data set created?

How was the data set created?

1. From what previous works were the data drawn?
2. How were the data generated, processed, and modified?

   Date: 2019 (process 1 of 1)

   Topographic measurements were made at Dam Reach pool (DMPOOL) and at Sleepy Hollow pool (SHPOOL) in water years 2014, 2015, 2016, 2017, and 2019 using a total station and a surveyor wading with a prism rod. Survey control was established using static GPS occupations on benchmarks. Survey control network densification was conducted using closed traverses with a total station. For the 2015 survey, a kayak-mounted single-beam echosounder was used in conjunction with a robotic total station to augment the regular total station surveys. All data were collected in NAD83 UTM10N horizontal coordinates and NAVD88 Geoid 12B vertical coordinates, in units of meters. Person who carried out this activity:

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?
   No formal attribute accuracy tests were conducted
2. How accurate are the geographic locations?
   Initial survey control for all topographic transects was established using static GPS occupations, which have an estimated horizontal accuracy of around 1.5 cm. Survey control densification was completed using a closed traverse with a total station. Topographic measurements were completed with a total station, and a surveyor wading with a prism rod. Repeat check measurements conducted during the surveys on points with established coordinates suggest a horizontal precision of less than 2 cm for these measurements. In 2015, a kayak-mounted single-beam echosounder combined with a robotic total station was used to augment the total station surveys. The horizontal precision of these measurements is estimated to be similar to those of the total station points, around 2 cm. Additional horizontal errors resulting from the echosounder beam width, and errors resulting from echosounder tilt are unknown.
3. How accurate are the heights or depths?
   Initial survey control for all topographic transects was established using static GPS occupations, which have an estimated horizontal accuracy of around 1.5 cm. Survey control densification was completed using a closed traverse with a total station. Topographic measurements were completed with a total station, and a surveyor wading with a prism rod. Repeat check measurements conducted during the surveys on points with established coordinates suggest a vertical precision of less than 2 cm for these measurements. In 2015, a kayak-mounted single-beam echosounder combined with a robotic total station was used to augment the total station surveys. The vertical precision of these measurements is estimated to be similar to those of the total station points, around 2 cm. Additional horizontal errors resulting from the echosounder beam width, and errors resulting from echosounder tilt are unknown.
4. Where are the gaps in the data? What is missing?
   Data set is considered complete for the information presented, as described in the abstract. At most survey sites, there are six transects. However, there are only four transect at DeDampierre Lower (DDL) and Schulte Road (SR). Users are advised to read the rest of the metadata record carefully for additional details.
5. How consistent are the relationships among the observations, including topology?
   No formal logical accuracy tests were conducted
