Landmark trees in Austria

This data repository contains 72 pictures of landmark trees and their surroundings from nine different regions in Austria, which we classified into alpine (i.e., taken in mountainous areas including Salzburg, Tyrol, and Styria) and flatland, which included locations in Lower Austria and Vienna. All pictures were taken in the summer of 2023. By landmark trees, we refer to remote trees that aid in wayfinding during outdoor navigation. 

The data set consists of one folder with the 72 pictures and one CSV file containing the following attributes for each tree: 

• Geographical coordinates (latitude, longitude) in the WGS84 coordinate reference system (CRS).
• Species classification, determined either by a biologist, utilizing PlantNet [1], or data sourced from the Vienna Baumkataster [2].
• Species categorization (deciduous or coniferous).
• Environment designation (alpine or flatland) indicating the location type where the tree was situated.
