Burton Island (1949) -- Discussion: Questions, Comments and Coordination

[Michael]

The voyage for 1949 has been done! Many thanks to Jorgito-kun, Sleepy Owl, Komodo137, cquaye and d0cent! You can see a plot of the voyage here and, for more detail, you can download the KML file and view it with Google Earth.

Here is a summary of the data:
There are 8363 records for Dir
There are 8579 records for Kts
There are 8722 records for Baro
There are 8748 records for Dry
There are 8086 records for Wet
There are 255 records for Water
There are 59 records for SeaT
There are 8569 records for Weather
There are 5898 records for Low
There are 1040 records for Mid
There are 399 records for High
There are 8397 records for Ceil
There are 6936 records for From
There are 8076 records for Amount
There are 8638 records for Vis
The total number of weather records: 90765
The total number of positions: 8766


If you wonder how well you're doing, this should be a good example:

When I have completed calculating all the hourly positions, I run several checks on the weather data, looking for values out of range, large changes in successive values, alpha characters in numeric fields etc. I have noticed that transcriptions of typed logs generate many more errors than do transcriptions of ones that are handwritten. The previous voyage I worked on, and which had the original handwritten logs, had just three errors, all from the log keeper, who had two winds SEE and one SWW. This set of typed logs had over 100 errors, I gave up keeping track, and the ones I checked were all transcribed as shown on the log page. I gave up looking at every page flagged, because so many of the errors that I checked were entered as written. Errors that had an obvious fix, like: 29.92 39.92, 29.92, etc, I could fix the error without looking at the page.

So, errors: Log keeper 3, typist 100, transcribers 0.

It's great seeing it done, after much toil. I can imagine even more rejoicing whenever an entire ship (all years) is completed.
