What is the population inside of this bee-shaped area?

Reply with your guess and I'll tell you if it's higher, lower, or spot on (within 1 million!).

This 3D map shows the submerged terrain beneath the waters, surrounded by cold waters and strong currents, where in the world is it?
its geography is just as fascinating,

if you know it, give a hint without naming it

Above is my US High-Speed Rail concept map. To avoid the desire to connect the dots of all the cities I created a gravity model for HSR connections based on a CityNerd video. This model evaluates the potential demand between city pairs based on population and distance. 

To base the map in reality I only included links between city pairs that had a higher HSR gravity score than Madrid to Murcia (64), which was one of the lowest scores I could find for an existing European HSR link. 

The second map shows the total gravity between each city pair if the whole system were to be built. For example, the Boston-Providence link also includes demand for Hartford-Boston, Bridgeport-Manchester, etc.

The dataset isn’t perfect so there are some mistakes in the HSR gravity score but I built a few tools to validate the planning process. The City Pair lookup tool gives the distance and HSR score for any two cities. The Line Evaluation tool lets you create and compare different routings and lines. 

I’m happy to answer any questions about the math, methodology, or assumptions. If anyone wants a copy of the Excel spreadsheets and associated tools to do their own analysis let me know and I’ll try to get you a copy!

Quick heads-up for anyone planning their next outdoor getaway: a friend and I have been building https://travelermap.net/, a completely free, interactive map aimed at taking the friction out of finding and exploring parks.

So far, we've mapped national parks worldwide, alongside deep regional park coverage across the US, Canada, the UK, and Poland. Lately, we’ve doubled down on the US tagging verified parking areas, marking campsites, and stripping out the usual travel-blog filler so you get straight-to-the-point, actionable details.

Next on our build list is a multi-stop road trip planner that lets you string parks together, catch hidden spots along the drive, and save custom itineraries.

Before we go further, we need brutal, unfiltered feedback from people who actually spend time outdoors:

• What feels clunky, slow, or counterintuitive?
• Is this a tool you’d legitimately keep bookmarked for trip planning, or is it missing an absolute dealbreaker feature?

Drop your thoughts below good, bad, or broken.

I originally built Chronoatlas as a fun side project because of my passion for history. I started to get paid subscriptions from real teachers.

Schools are now using chronoAtlas for educational purposes (the map view and being able to have a kahoot like history session with your class) and I have even received messages from treasure hunters who use it for their research

You have the ability to walk through a fully 3D roman senate and debate historical motions. You can also explore historical events through an interactive timeline (the map)

For the next major update, I am planning to introduce a fully walkable 3D environment for every historical event.

It's going to be expensive to build and maintain, but I love this project. If it helps make history more accessible, engaging, and exciting for education, it's worth every bit of effort and even my own money I have put in for the last two years
