The Problem
• Cemetery Department– Application to Search and Locate Cemetery
Plots• Make it accessible by the public
• Easy to use search commands
• Only show specific attributes
• Print maps of the cemetery
• Have database updated regularly by Cemetery Dept.

– Sex
• Map showing Spatial Location– Location of Burial Block, Lot
and Space
• Link– Database– Spatial Location
Digital Data with Attributes• Created Shapefiles

• Created Point Database– Burial Block
– Burial Lot
– Burial Space
CAD Drawing• Digital Cemetery Layout

Database Evolution

Access Database
SQL Database
Entered Burial Locationand Interment Detailsinto Access Database
Imported Data intoSQL Database
Building a Link
• Spatial Data (Shapefiles)• Database (SQL Table)
Burial BlockBurial LotBurial Space
Unique ID to tie tables together
Space ID - BCL104S5Lot ID - BCL104SBlock ID - BCLS
B + “Block” + L + “Lot” + S + “Space”
Joining Tables
• 1 to 1 join
– Space ID – BCL104S5
• 1 to Many join
– Lot ID BCL104S
– Block ID BCLS
• Field check records with incomplete data
Records are old anddon’t always have thefull burial location
• 52,000 cemetery locations• 28,000 interment records are linked

Maintenance
• Cemetery inputs new and updated records into a database interface• ITS Dept. stores and backs up the data through a SQL Server
– Unique ID (number) Field– Data Added Field– Date Modified Field– Exports new records into temporary table in the GIS database
• Once a week through script (local package) based on date added or date modified
• GIS Dept. pulls in new and updated records from temporary table– Creates ID from Block, Lot, & Space to link to spatial point
• Once a week through script (local package)– Verify that all records join properly– Website is automatically updated
Other Search Applications
• Other Cemeteries in the City (Pending)• Dedicated Tree Locator (Pending) • Bicentennial Park Brick Locator - Created using ArcIMS
