The project involves a detailed analysis of the potential impact of sea level rise on Miami Beach, Florida, using ArcGIS Pro 3.3 and ArcGIS 3D Analyst extension. The study uses data from NOAA's Digital Coast and the ArcGIS Living Atlas of the World to model intermediate-high climate scenarios for the years 2030, 2050, and 2090. The primary goal is to visualize and analyze how rising sea levels will affect the city's infrastructure over time and help in planning and designing resilient urban futures.
Key Steps and Components
3D Model Creation:
Using ArcGIS Pro, a 3D model of Miami Beach is created by extruding building footprints and joining height data to represent varying building heights accurately.
Additional details, such as realistic roof shapes, are incorporated using multipatch layers and procedural symbology from an RPK file.
Sea Level Rise Data Integration:
Sea level rise data for the years 2030, 2050, and 2090 are added from the ArcGIS Living Atlas.
The data are converted from raster to polygon format to enable more precise spatial analysis.
Impact Analysis:
The analysis identifies buildings affected by sea level rise in 2030, 2050, and 2090 by calculating inundation based on intersecting sea level rise polygons with building footprints.
Affected buildings are recorded in a new attribute table field for each time frame.
Visualization:
The results are visualized by symbolizing buildings according to the year of inundation, using color schemes to differentiate the impact over time (e.g., green for not affected, yellow for 2030, orange for 2050, red for 2090).
3D exploratory tools, like the Elevation Profile, are used to understand why certain buildings are not affected, often due to their higher elevation.
Sharing and Collaboration:
The final 3D scene is shared as a web scene to ArcGIS Online as part of the 2024 GIS for Climate Action MOOC.
