Of the 1971 voters in this election, 740 cast ballots. Craig Allan, Maurizio Napolitano, Laura Mugeha, and Héctor Ochoa Ortiz are the winners after counting the ballots using Scottish STV.

We have bike routes all over, and they are signed with something as shown.

But most of these will have a bike lane or sharrows along with the Bike Route signs.

However, I ran into one road that doesn't, it's just signed.

What's the best way to tag these roads? I don't want to cause confusion, but these unpainted (but signed) roads do actually lead to/from better cycling infrastructure, so they should be known.

UPDATE: Thanks for all the input, guys. Having looked into this further, I'm comfortable using the designated tag, at least for this specific road.

My municipality is a bit bipolar with their application of these signs. Most are signed as bike routes with toad markings, but a few are signed only.

Because these "bike routes" connect to more significant cycling infrastructure, I think its more than valid to tag them as “designated” as opposed to "yes" (which would be pretty much every road).

To add even more confusion to the situation, the official Cycling infrastructure map for my municipality seems to not include several areas that have both bike route signs and road markings, so i will ask them if the data is just lagging or if it needs to be updated.

So, unless there's a critical reason why the "designated" tag shouldn't be used in this context, I will leave it at that.

I'm on Street Complete and I'm trying to differentiate between Concrete, Concrete slabs, and concrete lanes. There's a walkway that's just a normal concrete walkway, I didn't know there were so many designations for this.

I know that is at first a geo database but has anyone build a better web ui where i can plan routes with public transport just like on google maps

Edit: I have found one which works for me: Mapy.cz it isn't open source but that wasn't a requirement

How do I make an office appear on OpenCycleMap?

The local representation of the German Cyclists' Association has an entry on OpenStreetMap and has tools and an air pump for cyclists on site.
We would like the association to appear on OpenCycleMap as well. For this purpose, both service:bicycle:pump=yes and service:bicycle:repair=yes have been set for the node.
It's been more than a week since the according changes were made - unfortunately I still can't see the location in OpenCycleMap. Any ideas what to do?
#OpenCycleMap #OpenStreetMap

For our parkour group, we have a list of spots with custom pictures of the spots, embedded right into google maps, so you don’t have to click on any other website. This is quite cool and convenient. Is there any way to move that list (manually is ok) to OSM? E.g. in a city guides functionality, which I have some memory of, but don’t know where it comes from.

When I first tried OsmAnd a few years ago it was overwhelming, there is so much to customize.

I tried it again recently and it really impresses me.

My OsmAnd ski profile shows me slope for avalanche risk and 3D relief so I don't need Fatmap, plus OsmAnd let's you download 7days of weather.

OsmAnd doing routing on hiking trails replaces my need for Gaia.

Really impressive work by the OsmAnd team.

Make Vector Topographic Maps (Open Street Map, Maperitive, and Inkscape)

by Michael Altfield

This guide will show you how to generate vector-based topopgraphic maps, for printing very large & high-quality paper wall maps using inkscape. All of the tools used in this guide are free (as in beer).

How-to Guide to Making Vector Topo Maps with Maperitive and Inkscape

Intro

I recently volunteered at a Biological Research Station located on the eastern slopes of the Andes mountains. If the skies were clear (which is almost never, as it's a cloud forest), you would have a great view overlooking the Amazon Rainforest below.

Yanayacu is in a cloud forest on the east slopes of the Andes mountains, just 30 km from the summit of the glacial-capped Antisana volcano (source)

The field station was many years old with some permanent structures and a network of established trails that meandered towards the border of Antisana National Park -- a protected area rich with biodiversity that attracts biologists from around the world. At the top of the park is a glacial-capped volcano with a summit at 5,753 meters.

Surprisingly, though Estacion Biologicia Yanayacu was over 30 years old, nobody ever prepared a proper map of their trails. And certainly there was no high-resolution topographical map of the area to be found at the Station.

That was my task: to generate maps that we could bring to a local print shop to print-out huge 1-3 meter topographical maps.

And if you want to print massive posters that don't look terrible, you're going to be working with vector graphics. However, most of the tools that I found for browsing Open Street Map data that included contour lines couldn't export an SVG. And the tools I found that could export an SVG, couldn't export contour lines.

It took me several days to figure out how to render a topographical map and export it as an SVG. This article will explain how, so you can produce a vector-based topographical map in about half a day of work.

Assumptions

This guide was written in 2024, and it uses the following software and versions:

1. Debian 12 (bookworm)
2. OsmAnd~ v4.7.10
3. JOSM v18646
4. Maperitive v2.4.3
5. Inkscape v1.2.2

The Tools

Unfortunately, there's no all-in-one app that will let you just load a slippy map, zoom-in, draw a box, and hit "export as SVG". We'll be using a few different tools to meet our needs.

OsmAnd

OsmAnd

OsmAnd is a mobile app.

We'll be using OsmAnd to walk around on the trails and generate GPX files (which contain a set of GPS coordinates and some metadata). We'll use these coordinates to generate vector lines of a trail overlaying the topographic map.

If you just want a topographic map without trails (or your trails are already marked on OSM data), then you won't need this tool.

In this guide we'll be using OsmAnd, but you an also use other apps -- such as Organic Maps, Maps.me, or Gaia.

JOSM

JOSM

JOSM is a java-based tool for editing Open Street Map data.

We'll be using JOSM to upload the paths of our trails (recorded GPX files from OsmAnd) and also to download additional data (rivers, national park boundary line, road to the trailhead, etc). We'll then be able to combine all of this data into a larger GPX file, which will eventually become vector lines overlaying the topographic map.

You can skip this if you just want contour lines without things like rivers, roads, trails, buildings, and park borders.

View Finder Panoramas

Have you ever wondered how you can zoom-in almost anywhere in the world and see contour lines? I always thought that this was the result of some herculean effort of surveyors scaling mountains and descending canyons the world-over. But, no -- it's a product of the US Space Shuttle program.

In the year 2000, an international program called SRTM (Shuttle Radar Topography Mission) was launched into space with the Endaevor Space Shuttle. It consisted of a special radar system tethered to the shuttle with a 60 meter mast as it orbited the earth.

This illustration shows the Space Shuttle Endeavour orbiting ~233 kilometers above Earth. The two anternae, one located in the Shuttle bay and the other located on a 60-meter mast, were able to penetrate clouds, obtaining 3-dimentional topographic images of the world's surface (source: NASA)

When the shuttle returned to earth, the majority of our planet's contours were mapped. This data was placed on the public domain. Today, it is the main data source for elevation data in most maps.

While the data from SRTM was a huge boon to cartographers, it did have some gaps. Namely: elevation data was missing in very tall mountains and very low canyons. Subsequent work was done to fill-in these gaps. One particular source that ingested the SRTM data, completed its gaps, and made the results public is Jonathan de Ferranti's viewfinderpanoramas.org.

We will be downloading .hgt files from View Finder Panoramas in order to generate vector contour lines for our topographical map.

Maperitive

Maperitive

Maperitive is a closed-source .NET-based mapping software (which runs fine in Linux with mono).

We'll be using Maperitive to tie together our GPX tracks, generate contour lines, generate hillshades, and export it all as a SVG.

Inkscape

Inkscape

Inkscape is a cross-platform app for artists working with vector graphics.

We'll be using inkscape to make some final touches to our vector image, such as hiding some paths, changing their stroke color/shape/thickness, and adding/moving text labels. Finally, we'll use inkscape to export a gigantic, high-definition .png raster image (to send to the print shop).

Example Maps

For example, here's the (A4-sized) topo map that I built for Yanayacu.

Final (raster) export, ready for sending to the print shop (source svg)

Note that I changed the stroke and thickness of the National Park boundary to be large and green, I changed the path of the road (downloaded from OSM data in JOSM) to be thick and black, and I changed my GPX tracks (recorded in OsmAnd and merged with the OSM data in JOSM) to be thin, dashed, and red.

I also used this method to generate a simplified "trail map" of Yanayacu (without contour lines). The workflow was similar, except I didn't generate contour nor hillshades layers in Maperitive before exporting as a .svg

(#foss @organicmaps is terrific both at navigation and mapping)

I am using a fresh osmand install, and now I have this widget on the right showing the wrong altitude. Always about 50m too high. The bottom widget shows the correct altitude however, that is kinda weird. I have updated the app now, but same thing.

Using f-droid latest version, but this happened also with the one I had before (4.85). I am also using brouter plugin for navigation, maybe the correct altitude comes from there idk. The wrong one is also displayed when in the default profile with no brouter involved.

Anybody else seeing this phenomenon?

Oh and the "centre map" altitude doesn't seem to be working at all, but I don't need that anyway.

I've been playing around with Google Maps lately to create custom maps.

I don't like google but have no experience with any other apps and have never tried mapping of any sort before.

I'm trying to create a map layer(s) that has historic sites, stone circles, woodland, cemeteries, UNESCO sites etc. So if I'm traveling I can stop and see them.

I've created my own Google Map using lists of sites from Wikipedia. This has gone ok but leads to a lot of data cleansing and the functionality isn't great.

I've seen this website but it isn't as complete as the Wikipedia text lists ive imported: https://www.hmdb.org/

I'm completely new to this and have no experience. Are there any good resources out there for me to use or contribute to?

I'd like to de-google as much as possible.

P.S. do I need to enable developer mode or root my phone to install open street map now?

Thanks!

@openstreetmap A while ago I've seen a before-after screenshot command line tool for osm mentioned somewhere but I cannot find it anymore.
I believe it was written in python.
Does anyone know the name of the tool in question?
