This app makes it easier to enter measurements from cave surveys written on the typical staggered table style sheets!
Just drag and drop image files of your survey notes into the left
pane. After a moment they will appear with a table overlaid outlined
in red. Drag the corners of the red rectangle to fit the table to
the image, then click in the text fields and begin typing in the values.
Use tab/shift + tab or the arrow keys to go through the fields
quickly.
The data is saved in local storage, so it should come back up if you reopen the page later on the same device and web browser.
Once you've entered values, the formatted data will appear in the right pane. At the moment only the survey data format we use at Fisher Ridge is supported, but I'll add Compass and Walls soon.
