Custom-Gathered Dataset: Stevens-Sky2Ground

We collect two multi-altitude datasets with ground truth GPS for two different sites. Each contains aerial imagery collected by UAV and ground imagery collected by handheld device. One high-resolution satellite imagery from Google Earth Pro is also included for each site. Ground-level GPS is achieved by RTK GNSS using EMLID Reach RS+ receivers.

Stevens Institute of Technology Campus

This dataset contains 179 aerial images, 186 ground images and 1 satellite image.

Raritan Bay Waterfront Park

This dataset contains 174 aerial images, 139 ground images and 1 satellite image.
