Spanning a series of islands in a shallow lagoon, the city of Venice is renowned for its beauty. But that beauty comes at a cost. The lagoon's tidal patterns mix with the islands' low elevation to cause acqua alta (high water), a periodic flooding that affects most of the city. Although not a threat to human life, acqua alta impedes transportation and endangers Venice's priceless architecture—and the problem is getting worse.
Historically, an exceptional tide (defined as 1.4 meters above sea level) occurs about every four years. In the past decade, however, exceptional tides have become an annual event. Efforts to chart, analyze, and control acqua alta will be crucial to protect Venice in the future.
In these lessons, you'll travel to Venice with ArcGIS Pro. You'll build a 2D map of the city with canals, structures, and some of Venice's most famous landmarks. Then, you'll convert the map into 3D. You'll analyze and quantify the threat of acqua alta, before giving your scene a realistic appearance to show others.
