HamMap.io: Marcin’s Solution for Visualizing Boundaries in POTA/SOTA Activities

14 Comments

Many thanks to Marcin (SP5ORI) who writes:

When I started activating parks and summits last year, I searched for an app to visualize park boundaries, but none met my needs. While there are many applications for POTA and SOTA activators, none offered this specific feature…

Check this out: https://www.hammap.io

Countless times I heard, “It would be great to see park boundaries…” followed by, “This can’t be done” or “That’s impossible.” I took on the challenge, and this is the result.

I’ve recorded three videos to showcase the app, available on YouTube:

More Features:

What makes this app special?

    • See parks and summits on one map
    • View park boundaries (currently includes ~98% of Polish parks)
    • Voivodeship shapes for Poland
    • Country shapes
    • Spatial relations (N-fers)
    • Determine if a summit is in a park
    • Identify parks within another park
    • Find nearby summits
    • Flags
    • Powerful general search
    • Explore details at any point on the map
    • Activation spots

The app is still a work in progress, and we’ll be adding more areas soon.

What do you think?

Randall says, “The World is Flat!”

The world is flat! Just ask any Ham!

It’s funny, but true. The World of Amatuer Radio is flat!

We often think we know the direction to a DX contact, but we seldom do. Especially at distances beyond 1,000 miles. Therein lies the misconception in our DX radio reality.

We assume this spherical, oblate ellipsoid, we call Earth, as round. In fact, it bulges at the equator, flattening the poles. Ergo, our sense of direction is wonky… Lets fix that. Here’s a link. https://ns6t.net/azimuth/azimuth.html

Here is a copy of my Azimuthal Map from DN13tq:

The center of my universe is Boise, Idaho, specifically DN13tq. Using the NS6T.net website, you too can enter your Maidenhead coordinates and see your radio world in a whole new light. Download your own Azimuthal Map and see the World as flat.

Europe, for me, is not East. If I had a log periodic beam, I’d be talking to Cape Town South Africa at 90 degrees east. Europe (for me) is 30 degrees NNE from my QTH. As a QRP field operator, I should orient whatever gain, in whatever field antenna I may have, accordingly. Just saying… The World of Amatuer Radio is flat!

So get properly oriented, and go out and discovery New Worlds.

Alan’s POTA Mapping Tip!

7 Comments

Many thanks to Alan (W2AEW) who shares the following tip:

Thomas,

I don’t know about you, but sometimes I find it hard to locate maps for the national and state parks. Some of the parks have good maps on their websites, some do not. Others have maps, but they aren’t detailed enough sometimes to definitively determine if you’re within the boundary or not.

I’ve found that one of the best sources for the national, state and local park boundaries is OpenStreetMap.org. This is a free mapping site. One missing piece is that it does not map National or State Trails very often. But, for park boundaries, it is great.

For example, this map clearly shows that most of Barnegat Light State Park (K-1609) is also within the boundaries of the NJ Pinelands Reserve (K-6609). From experience, I know that this also falls within the NJ Heritage Coastal Trail (K-6544) – thus making it a 3-fer.

At my early activations from this park, I did not know that it was part of Pinelands and thought it was only a 2-fer.

I have also used an app called “onX road” on my phone which can show owners of properties, but in order to see that, it isn’t free.

Just another tool for your toolbox.

Thank you for the tip, Alan! I have not used OpenStreetMap.org as a POTA tool, but I certainly will moving forward. 

I have been using the free app, Parceled, on my iPhone to discover the owners of land parcels–it works brilliantly and is free (so far).

Thanks again, Alan!

The Indispensable Gazetteer

11 Comments

If you live here in the States and like to play radio in the field, I highly recommend one of the DeLorme Atlas & Gazetteer issues.

Although I use electronic devices like smart phones and dedicated GPS, it’s always nice to have a paper map. I always have one of these Gazetteers in my car. You should never be without a paper map, I say.

I love the Gazetteer because it shows lines of elevation and every/any possible road and trail.  It’s incredibly useful for finding summit road and trail access points and also for finding game land entry areas.

Funny, but I opened my new Gazetteer while still in the parking lot of the camping store and almost instantly spotted a brilliant new access point for the Overland Victory trail in Morganton. It’s an even better activation spot than I’ve used in the past.

Last year, I wanted to purchase the latest edition for North Carolina but I’m sure due to the pandemic, they were as rare as hens teeth!

The other week, I found one in a local camping store and grabbed it! The store owner told me he’d only gotten a handful in recently and had been out for months. Check for one at your local camping store, book store or outdoor center. If you can’t find one there, check Amazom.com (affiliate link).

I’m a huge map geek. Although I don’t recall them including topographic information, when I lived in the UK, I was a massive fan of A to Z road maps for their design. I’d love to know if there’s a topo map equivalent.

If you live outside the US, I’d love to know what maps you use for your field activities! Please comment!
