The Problem

• Cemetery Department– Application to Search and Locate Cemetery

Plots• Make it accessible by the public

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
