Hello hello! Another three years have passed, and the quiet local @openstreetmap conference in Eastern Europe is coming to Riga once more!

Just for one day — 4 June 2026 — but we will sure plan something on the evening before and morning after. Subscribe to this account for news, register for the conference, buy plane tickets (sorry, no Rail Baltica yet), and think on your talk topic!

Everything's here: https://2026.sotm-baltics.org/

Interesting post about #openstreetmap waterway tagging. It mentions some new and rare types. I definately see flowline being used.

In years of openmap.lt existence we've created a number of different small web-apps for different purposes: general map, tourism, kayaking, craft-beer etc. But in next generation map we decided to put all of it into one web-app. Therefore we need "profiles", which would mean not only different map style (and thus different displayed and enhanced/hidden features), but also different legend/filter and different search capabilities. This lego brick we hope will give us lots of other possibilities.

We will see, code will be on github.
Global projects have other problems... but that is another complex story.
Maybe some neighbours could benefit... ;-)

We have a lot of products and services in Lithuanian 🗺️ openmap.lt family, but all of them were kind of forgotten.

So we've started a new project - ⏭️ NextGet aiming to refresh all of it:
* move all of the software to Lithuanian OpenMap association servers,
* move all code to github,
* refresh or rewrite software using todays technologies.

Work has already started on one of the oldest and most popular - places portal: https://nextgen.openmap.lt/#p/13.23/54.63631/24.94370/0/0

It's been a long journey (over year since I began), but there's finally now a first public release of the oblique hachures method. With many thanks to @SouthArrowMaps, who significantly refined the methodology from what I began with.

How WWI got Nat Geo got into the map business

Our first in-house map was produced during World War I. By the Second World War, the White House was asking for them by name.

~10 months after I developed it, I'm finally starting to write up details about my oblique hachure method. It's going to be a *long* process of explanation and refining my script to be usable by others. But, I've at least started down the path. Goal is to submit a draft to Cartographic Perspectives by October.

Perhaps a surprise given how much writing (& editing) I do, but it's always a slow struggle for me, disentangling my thoughts. Sometimes a short paragraph can take me an hour.
