Landslides of the 2023 summer event of São Sebastião, southeastern Brazil

<p>In February 2023, anomalously heavy rainfall caused widespread landslides in the coastal city of S&atilde;o Sebasti&atilde;o (Southeastern Brazil). This report describes the first version of a landslide inventory dataset for this event. The inventory is based primarily on the analysis of aerial images with 10 cm spatial resolution acquired immediately after the event, as well as archive images from Google Earth and PlanetScope. Delimitation of the landslides relied on a comparison of the images along with the area's Digital Surface Model (DSM) and hydrography. The GIS vector dataset (shapefile and geopackage) contains 989 points representing the landslide's crowns, 1,116 polygons indicating the affected areas of landslides and 1 polygon of a debris flow.</p>
