MUltiband Satellite Imagery for object Classification (MUSIC) to detect Photovoltaic Power Plants

MUSIC for P3 dataset

Overview

The number of photovoltaic power plants is growing so rapidly that we must rely on satellitel observations and efficient machine learning methods for the global monitoring. MUSIC for P3 (Photovoltaic Power Plants) is a training and validation dataset generated by AIRC/AIST to support such a global survey of photovoltaic power plants.

We have picked up the photovoltaic power plants listed on the website of Electrical Japan only if they generated more than 5MW electricity and the construction had been completed by 2015. The multiband satellite images of these target areas, taken by Landsat-8, were cropped into a 16 × 16 grid covering a 480 × 480 meter area as shown below.

These patch images are classified as “positives” if the solar panels cover more than 20% of the total areas, while patches with no solar panels are classified as “negatives”. The rest with the intermediate coverage (0~20%) were neither “positives” and “negatives”.

You can download the MUSIC for P3 dataset with two different format (HDF5 and GeoTiff) along with the source code for the detection and classification. More detailed exaplanations can be found in the following papers.

Updated dataset (V2)

It should be noted here that the "negatives" in the initial dataset (V1) is contaminated by small-scale photovoltaic power plants not included in the original inventory. After publishing these papers, we have checked all the false positives through in-site survey or high-resolution imagery. In fact, some of "false positives" are found to be relatievely small photovoltaic power plants unlisted in the original database. Therefore, we've produced updated V2 dataset by correcting these misclassification. The performance of our previous works was estimated with V1 dataset, but more accurate estimate can be achieved by using this updated dataset V2.
