+ADS-B Training Dataset (dump1090 Output)
+  Overview
+
+    This dataset contains ADS-B data captured using the dump1090 program. The data is organized into multiple directories, each representing a separate data collection session or environment. The dataset is designed for use in training and evaluating models related to aircraft signal analysis, localization, or reception quality prediction.
+
+    Structure
+
+    The dataset directory has the following structure:
+
+    train_data/
+    │
+    ├── ali/
+    │   ├── home/
+    │   └── ottawa/
+    │

+    ├── .gitattributes
+    └── README.md
+
+  metadata.csv
+
+    The metadata file provides descriptive information about each data capture session. It is a CSV file with the following columns:
+
+    Column	Description
+    file	Path to the data file relative to the dataset root
+    shorthand	Short identifier for the data collection setup
+    indoor	TRUE if the receiver was indoors, otherwise FALSE
+    unobstructed_0-45	TRUE if the view in this range (degrees) was unobstructed (a window counts as unobstructed)
+    unobstructed_45-90	TRUE if the view in this range was unobstructed
+    unobstructed_90-135	TRUE if the view in this range was unobstructed
+    unobstructed_135-180	TRUE if the view in this range was unobstructed
+    unobstructed_180-225	TRUE if the view in this range was unobstructed
+    unobstructed_225-270	TRUE if the view in this range was unobstructed
+    unobstructed_270-315	TRUE if the view in this range was unobstructed
+    unobstructed_315-360	TRUE if the view in this range was unobstructed

+
+  Data Source
+
+    All data files were generated using the dump1090
+     ADS-B decoder. Each file contains decoded messages from aircraft transponders received by an RTL-SDR device.
+
+Usage Notes
+
+The unobstructed flags correspond to 45° sectors around the receiver.
+
+Each data directory contains raw dump1090 output files.
