A solution to last week's challenge can be found here

This week's challenge was submitted by @wwatson  - Thank you for your submission!

For this week's challenge, you are the skipper of a large container ship destined for Belfast harbour. You must navigate through the exact centre of the navigation channel due to the large draft of your ship. The origin - current position of your ship, the destination and the locations of the channel marker buoys are provided.

Plot the marker buoys as lines showing the left and right buoys, and the route through centre of the buoys. Also calculate the length of the route through the channel from your origin to the destination in miles. Create a report snippet to show the route and distance.

First weekly challenge that I've been able to do for the last several weeks, and it was a fun one.

As usual, the reporting tools are tricky, but very robust if you know how to use them.

I love playing with spatial data! So intuitive to work out which tools to use.

Nice challenge. I didn't expect to say this anytime about a challenge using spatial and reporting tools ...

ARGGGGGHHH Reports.

I always learn something each time I do a challenge with a report, mostly I don't like reports.
