A dataset of UAV remote sensing images of Lanzhou Botanical Garden in 2021

Abstract

In the study, we used a small drone carrying a visual monitoring camera to obtain the spectral reflectance information of the red, green and blue bands in Lanzhou Botanical Garden. And on the basis of the drone data of Lanzhou Botanical Garden from March First to December 30, 2021, we prepared a dataset of remote sensing images. During the data collection process, the UAV conducted 72 aerial surveys, and took a total of 15,696 images. After aerial triangulation and orthophoto correction, we spliced the images to obtain the digital orthophoto map (DOM), and further calculated the vegetation index results. This dataset includes two kinds of data: DOM and vegetation index. Lanzhou Botanical Garden is located in Anning District, Lanzhou City, Gansu Province, with rich vegetation varieties and high spatial heterogeneity in the study area. This dataset has certain potential for researchers to explore in urban vegetation phenology, urban ecological monitoring, and urban thermal environment.
