A Shiny mobile app for residents of St. Andrews Park, Venice, Florida.
What it does
- Maps 388 property owners across 14 subdivisions
- Search owners by name, address, or subdivision
- Shows Venice city boundary and demographic facts
- Lists nearby EPA-monitored beach conditions
- Links to city services, county resources, and community documents
Data sources
- Owners — Sarasota County Property Appraiser (SCPA); updated weekly via
data-raw/update_owners.R - Subdivision boundaries — Sarasota County GIS plat layer
- Venice boundary — Sarasota County GIS municipal boundary layer
- Beaches — EPA beach monitoring data
Weekly update
source("./data-raw/update_owners.R")
Downloads fresh SCPA data, joins to stable geometry, overwrites data/owners.rds.
Geometry
Owner point locations were geocoded via Google API, manually corrected in QGIS
(multi-unit buildings share a street address and required individual point placement),
and saved as data-raw/addresses/owners_moved.gpkg. This file is the stable geometry
source. Account numbers follow the property, so only ownership attributes need
refreshing weekly.
Note: building footprints not used
Sarasota County publishes a building footprint GIS layer that could derive accurate
centroids without geocoding. However the footprint layer carries only a street number
(buildingid) with no street name — making a direct attribute join to SCPA records
ambiguous across multiple streets. A spatial join via street centerlines would resolve
this but adds complexity. Since accurate geometry already exists in owners_moved.gpkg
and St. Andrews is a built-out community with no new construction, the footprint
approach was deferred. It remains the right path if the app is ever extended to
additional subdivisions.
