## What is CaveDiveMap?

CaveDiveMap is an app designed for cave diving survey and automated mapping.

The app requires a 3d printed measuring wheel which is attached to a waterproof dive case for your iphone.
The app measures the rotations of the wheel using a small magnet mounted on the wheel.
The wheel is clamped to the guide line using the 3d printed adapter.

The app records automatic data points each rotation of the wheel, but also the diver sets manual station/anchor points at each tieoff before starting to the next.
The app requires the diver to perform quick on the fly calibration before saving the next data point to ensure maximum accuracy in heading with stationary magnet.

This method allows for quick, automated one handed surveying of sumps and underwater caves using the guide line.


## Version history (last 5 releases)

### 1.7 — 2025-12-27

- Bug fixes
- Added button position and size customization 
- Added optical detection algorithm ( experimental ) 
   The optical wheel rotation detection is designed for a new type of encoder wheel which will not use magnets.

### 1.6 — 2025-11-28

* BUG fixes and new features

* Fixed a bug in Visual Mapper ( world orientation was using gravity and heading which caused systematic drift ).
    - Changed it to .gravity only

* Added 3d pointcloud viewer  
* Improved PDF export from pointcloud viewer
* Moved settings button to the left ( divevolk case accidental touch fix )
* Changed button size on saving manual points ( divevolk case mod )
* Increased buttons and label text on manual data point save screen for better readability
* Added +10 increment on the depth LRUD data screen ( must hold plus or minus button for 1+ seconds )

### 1.5 — 2025-10-21

Added support for labels to the Visual mapping tool. Now the user can add names of sections of the cave or interest points which are later exported with the pointcloud.

### 1.4 — 2025-05-29

Small fixes on the Visual SLAM mapping method.
Added pointcloud viewer/analyzer

### 1.3 — 2025-05-26

- Added auto-save upon session reset ( line survey mode ) or upon exit ( 3d vSLAM, VIO method )
-> survey files are saved on disk in the app's Documents folder. They can be accessed via the files app in ios.

- Fixed live map preview. It was drawing segments with incorrect lengths. 

- Improved magnetic rotation detection calibration algorithm.
- Larger buttons, easier for dive-volk case or for new users to see the color coding.
