Tasks Collect GPS data for required portion of the San Marcos Cemetery Explore spatial resolution of available GPS devices Model the layout of the San Marcos Cemetery Apply the Pontem software methodology and file geodatabase architecture to collected data.

Progress on Task 1 Collect GPS data on sections A1-A3 in the Ramsay Addition In Progress Section A3 is completed after several trials of different collection methods. Met with Ron and Pete on the 19th and solidified data collection method. Collect data for the Section and Block boundary, we digitize the individual graves.

Progress on Task 4 Apply the Pontem software methodology and file geodatabase architecture to collected data. In Progress Most of A3 has had the attributes populated consistent with Pontems’ standard. Waiting on creating a file geodatabase until data is near complete.

Conclusion Everything is going well. We will continue to collect GPS data on almost every Monday and Wednesday. Post Processing of the GPS data happens either the day of collection or soon after. Changes to the attribute data may happen depending on how the Citys database is laid out.
