Lab 2
Introduction
o Provide background to the problem at hand. What are the problems and challenges facing Hadlyville cemetery?
All original records and maps of the Hadleyville Cemetery have been lost. There are multiple burials with out any identification markings, and stones dating back to 1800 that are difficult to read. Our 336 class has to figure out a way to map the headstones and burial plots.
o Why is building a GIS of this project better than a simple map and/or spreadsheet?
A GIS will have exact locations with exact coordinates of burial plots occupied as well as unoccupied.
o What equipment are you going to use to gather the data needed to construct the GIS; ie what is the overall approach?
The approach is to take the aerial image and join it with the GPS coordinate points taken in the field.
Only a few points were taken by GPS, so the rest of the headstones must be marked on the aerial image.
o What are the overall objectives of the method being employed to gather the data.
The goal of the proposal is to identify as many stones and burial sites as possible. The UAS took an image that we, as a class, will use to make a map of the headstones in a GIS.
Methods
o What combination of geospatial tools did the class to use in order to conduct the survey? Why?
A surverying GPS to collect the coordinate points (for four rows)
A UAS to capture the 1.5 acre field in an aerial image
A GIS to join together the aerial image and the coordinate points to get an accurate layout of the cemetery.
o What is the accuracy of the equipment you are intending to use? (Be sure to cover each piece of equipment)
Drone: ~1 meter
Surveying GPS: ~10 cm
o How was data recorded? List the different methods and state why a pure digital approach is not always best. What media types are being used for data collection? Formats?
Some data was written down by students. Some people took pictures of the headstones as a backup. A pure digital approach is not the best because the image might get lost or data might become altered. A hard written copy is always good to have on hand.
o How will you transfer the data you gather into a GIS
Put the coordinates into an excel file and the join the data into a GIS with the aerial image in the background.
o What equipment failures occurred if any? What was done to remedy the situation?
The surveying GPS took way to much time, so we stopped using it after the completion of row four. The surveying GPS was not entirely necessary because we did not need that precise of a reading. The UAS was the major piece of equipment that was needed.
o What might have been done to facilitate data collection in terms of equipment and refining the method?
As a class we could have worked together more to figure out who was recording certain rows or taking pictures. We also didn't exactly need the surveying GPS because of the images we took in the air.
Conclusion
o How did the methods transfer to the overall objectives of the project?
o How did the mixed formats of data collection relate to the accuracy and expediency of the survey?
o Describe the overall success of the survey, and speculate on the outcome of the data.
