+# Dataset description
+
+Mosaic REALMAP Demo dataset with 9114 images collected with panoramic camera with global shutter sensors. You can find more about full dataset in this article: [Mosaic Prague REALMAP](https://www.mosaic51.com/featured/mosaic-realmap-explore-prague-in-unprecedented-detail-with-1-26-million-images/) Each image has its position written in EXIF metadata populated from IMU device paired with the camera.
+Images from each sensor are electrically syncronized up to several nanoseconds and the whole device can be considered as a multicamera rig. Additional camera information, including .gpx track is attached here also.
+Camera calibration is provided in COLMAP compatible format.
+
+## COLMAP project example
+
+Dataset contains a small COLMAP project example, including .db, project.ini and exported model. It also includes depth map project with extracted dense point cloud
+
+# TODO
+* Explain calibration format, share full .json calibration and visualization script
+* Provide imu2camera calibration, provided poses for all images
