+# Binary Map Creator for Active Regions with Polarity Inversion Lines
+
+## Dataset Summary
+
+This dataset provides binary segmentation maps (4096×4096 resolution) derived from Solar Dynamics Observatory (SDO) magnetograms. The maps highlight regions containing Active Regions (ARs) and Polarity Inversion Lines (PILs). The data spans observations from January 2011 to July 2024 and is intended for image segmentation tasks using full-disk 4096×4096 magnetogram rasters as input.
+
+## Supported Tasks and Applications
+- `segmentation`: Binary segmentation of solar magnetograms to identify ARs with embedded PILs.
+
+## Dataset Structure
+
+### Data Files
+
+- `train.csv`: Input list for 2011 data
+- `val.csv`: Input list for 2012 data
+- `test.csv`: Input list for 2013 data
+
+To create other train, validation, and test set, use these files
+- `ar_2011.csv`: Data for 2011
+- `ar_2012.csv`: Data for 2012
+- ...
+- `ar_2024.csv`: Data for 20124
+
+### Features
+Each .h5 file contains two keys:
+- `intersection`: Binary map of polarity inversion lines (PILs)
+- `union_with_intersect`: Binary map of active regions that contain PILs
