Interactive Dashboard - Geospatial Impact Analysis of Tweets

This workflow demonstrates the use case of a geospatial impact analysis of tweets posted during Hurricane Ian, which made landfall near Cayo Costa in southwestern Florida on September 28, 2022. It is based on the “Geospatial Impact Analysis of Hurricane Ian on Tweet Sentiment” example workflow which is available for download from the Geospatial Analytics Examples space.

The purpose of the workflow is to visualize the tweet’s sentiment in relation to the hurricane’s path and how the poster’s distance to the hurricane affected the tweet's sentiment score. Additionally, the workflow contains an interactive dashboard that allows the user to specify the exact time period for which the sentiment score should be reported.
