Introduction
What are the problems and challenges facing the Hadlyville cemetery?
The first problem that the cemetery faces is the loss of all records and maps that detail who is buried in the cemetery and where in the cemetery they are buried. Hadlyville has been in use since 1865 and many of the tombstones may be broken or eligible.
Why is the loss of original maps and records a particular challenge for this project?
The data must now be generated from scratch due to the fact that there is no background material to reference.
How will GIS provide a solution to this problem?
GIS allow the creation of an attribute table that will be attached to shapefiles that represent the individual plots located the cemetery. The attribute table will contain all of the information that can be gathered from the cemetery.
What makes this a GIS project, and not a simple map?
Due to the fact that the data will be entered into a geodatabase that can be view, analyzed and updated makes the project more than a simple map.
What equipment are you going to use to gather the data needed to construct the GIS?
A GPS units, field notebooks and a UAV Drone.
What are the overall objectives of your proposal?
- To preserve community history by the development of a detailed and accurate map to define the burial lots of the cemetery.
- Eliminate the possibility of selling the same lot to multiple people.
- Identify as many stones and burials as possible and enter data into a geodatabase.
Methods
How was the data entered/recorded? Why did you choose this data entry method?
- We are going to use GPS units to first map out the boundaries of the cemetery by way of the tracks feature of the GPS unit. Secondly we are going to plot each lot with the GPS unit in an organized fashion. Starting in one corner and going row by row to the last row. For the field note book, data will be taken from each tombstone and recorded, to the best that can be deciphered, focusing mainly on these attributes, First and Last name, Gender, day, month and year born, day month and year of death, age, ligibility of tombstone, whether or not the tombstone is upright, condition of the tombstone, whether or not it is a shared stone, what religion is referenced, and finally what type of tombstone.
The UAV will take aerial images of the cemetery that will be used as the base layer for the map.
What is the accuracy of the equipment you are intending to use?
- The UAV uses a 16 megapixel camera that can show details down to the centimeter. The GPS unit is accurate to 3 meters.
What is the sampling technique you chose to use? Why?
- All tombstones were recorded to the best of the samplers abilities because the local county official needed a thorough record to replace the data that was lost. However due to age and weathering some tombstones were eligible and resulted in Null values in the database.
How will you transfer the data you gather into a GIS?
- All data that was recorded in the field notebook will be transferred over to an excel document. This document will be uploaded to ArcMaps as an attribute table and then joined to the waypoint shapefile that was created by the GPS unit. UAV image data will be transferred as a raster to ArcMaps to be used as the base layer. The waypoints and tracts will be loaded into the DNRGPS software program that can then be transferred to ArcMaps.
What drawbacks are there to the method you propose? How to the pros outweigh the cons of this method?
- The physical observations will be difficult to obtain in certain circumstances due to weathering, age and the material of the tombstones. Not all wanted attribute information will be available for each tombstone. The GPS unit is susceptible to bad reception due to cloudy weather and large amounts of tree cover. Some data will not be able to be collected as a result of human and equipment error. The data that can be recovered will be attached to the data points which represent the locations of each tombstone. The end product will result in an editable database and functional map that can be used by county government officials as well as the local community.
Conclusion
How do your methods transfer to the overall objectives of your proposal?
- This method will allow the creation of a manageable database containing both burial and plot information and a detailed map for the government records department. All current plots will be accounted for and documented which will help prevent the possibility of a single plot being sold to multiple parties.
