Kenosha Mapping about 10 hours ago

I don't see many polygons. The ground isn't even covered in polygons. There are many places (especially in Germany) where editing has become quite hard, as you keep accidentally clicking on polygons you don't want to touch.

And the polygons I see look not too bad in Kenosha. Note that they may be quite old too. Dating from a time where we had bad, or no satellite imagery at all.

It is true however that it's lacking a lot of data. There are no addresses, no points of interest, no shops, ... So you're certainly welcome to help in that area.

Hi, it looks like your city is already quite well mapped. http://www.openstreetmap.org/relation/2613238

All housenumbers are complete, most buildings are drawn.

If you know the city very well, it might be good to add all sorts of points of interest. All shops, pubs, restaurants, ... Including contact info, opening hours, ...

Just zoom in to a part of the map where the shop is (zoom in far enough, otherwise, loading the data will take a while). Then click on the "Edit" button, and either add a point of interest, or add data of an amenity to an existing address or building.

State Parks and National Parks 4 days ago

leisure=park is completely different IMO. It's normally a man-made area where certain flowers are planted, paths made etc.

You could use leisure=nature_reserve for those smaller parks. Though boundary=protected_area seems to be the newer choice.

What's new in uMap 5 days ago

Very nice improvements to see.

There are however some usability problems I experience as a first time user. Maybe you guys can give it a thought.

IMO, it's hard to know what name you should set to show that name to people when they click on something. It's hard to see a difference between editing map properties, layer properties and object properties. I suppose a header in the right panel, saying "editing map settings", "editing layer x settings" or "editing object y settings" would help. Maybe for objects, even a colour code or coloured symbol could be added to distinguish between unnamed points, ways and areas.

The browse data button (which is extremely handy to get to the right object) is also rather well hidden. In the right-click menu, it's between "help" and "about", which isn't where I'd expect it. It's also hidden behind the layers button, which isn't where I'd expect it either. "Browse data" doesn't offer you a lot of control over the layers (and isn't meant to do so). So putting it under the layers is strange IMO. It would be better if it could be an always-visible button in the right of the screen (somewhere near the editing of the map settings and the background layers buttons).

It should also be possible to "disable editing" without saving the map IMO. This would ensure you're doing stuff correctly if you can switch perspectives easily.

When making maps anonymously, it's also way too easy to just lose your editing URL, and be locked out of your map forever. So I suggest that the default for anonymous-made maps should probably be that everyone can edit the map (so you're not locked out). Next to that, signing up really gives you a better user experience (you don't lose your maps), so it should be highly encouraged. Either with a pop-up on the first usage (sign-in popups are quite normal), or with a Wikipedia-like banner when you start editing anonymously.

The help menu called "directions from here" could probably also be renamed to "create a route with OSRM", which also gives the opportunity to have links to other websites (that may have better support for bikes, pedestrians, ...).

Apart from those usability issues, one big feature I'm missing is an export-to-paper function. Either to image, or directly to multi-page atlases. The first could be used to get an image for some folder you can print (f.e. with the location of a few stores), the second could be used to document a travel, or a cycle route you made.

I think this will tun out to be a very useful app for the big masses. Thanks for all your work on it.

How do I indoor map my building? 5 days ago

Note that indoor mapping is still rather experimental, and also rather difficult, as GPS position is hard to get inside buildings (certainly for the precision you need), and areal imagery doesn't help a lot.

The only thing you can use are images of floor plans, as a background to the existing building layout.

Brugje 17 days ago

Je kan dat gerust zelf aanpassen. Nu je een account hebt moet je enkel naar het correcte deeltje van de kaart gaan (best zo diep mogelijk inzoomen), en "bewerken" (of "edit" als je in het Engels werkt) klikken.

Dan kom je in de bewerk modus, en kies je bovenaan voor "lijn" om je brug te tekenen. Klik dan op het beginpunt van je brug, en dubbelklik op het eindpunt om de weg af te sluiten.

Dan moet je nog het type weg kiezen in de rechter selectiestrook. Waarschijnlijk pad -> gewoon pad (aangezien het zowel door fietsers als voetgangers kan gebruikt worden).

Dan kan je de eigenschappen van het pad bewerken in de linker kolom. Je kan het een straatnaam geven (als er een is), en ook aanduiden dat het een brug is. De rest moet je niet meteen invullen, de meeste van de andere eigenschappen zijn maar belangrijk bij bergpaden.

Groeten, Sander.

intermittent streams in arid environment 18 days ago

As you're supposed to map regions you know (and don't do armchair mapping, except in some cases), a mapper can be expected to know how often there's water streaming there.

But as there are not a lot of populated places where streams are often dry, these tags aren't used very often.

If you know good worldwide definitions for all sorts of intermittent streams, with re-use of, or coherence with existing tags , I can only suggest you make a proposal. ( http://wiki.openstreetmap.org/wiki/Proposed_features )

I am looking library to access OSM data from Visual Studio or Android 6 months ago

Not exactly what you asked, but something like this could be handy too: https://play.google.com/store/apps/details?id=org.haptimap.offis.pocketnavigator

Though the last update was in 2012.

Hallo over 1 year ago

Sometimes you also can get reactions that you're mapping too precise. But the limit is quite a bit higher (if you see that in Germany, a lot of trees are mapped).

The biggest advantage of OSM (for me) is exactly that it's open. I can download the data, and display every feature on a map how I want it.

If you're interested in the technicalities, you can make your own maps with f.e. tilemill from Mapbox: http://mapbox.com/tilemill/ (although importing the OSM data can be a though job sometimes).

What to do with general "notes" ? over 1 year ago

If it's from anonymous users, I would just close it. They won't get a notification anyway, as they have no e-mail registered.

If it comes from a normal users (even without edits), I would try to explain what Russell said.

Editing: OSM's website vs Quest Map Open? over 1 year ago

Nothing fishy about it. MapQuest has very bad data when it comes to other countries than the US. So they like to use OSM data for this.

In return, and for their own profit, they allow you to edit OSM data directly from the MapQuest site.

So it's a genuine effort, but I don't know if it's technically best. Btw, Potlatch on OSM isn't perfect either.

Just started mapping actively in Brisbane - I have a few questions! over 1 year ago

To check alignment, fire up your GPS, walk around on some open place you know (like a parking, so you have a good reception), and remember where you walked (which side of the track etc).

Upload the GPX trace (you have to export it some way from your GPS) to OpenStreetMap, and check if there's a constant deviation of the imagery vs your trace.

It's normal that your trace is a bit imprecise, but if you see a 5m shift for your entire walk, you can assume the imagery is misaligned 5m.

On the other hand, a little shift isn't that bad. As most GPS devices aren't precise anyway, a 5m shift won't matter. And it can be fixed in the future when even better images will be available.

I've noticed that the closest zoom images are older, and have a bigger shift (at least in Belgium). So you should probably drag your outlines to comply with the second-closest zoom.

Stuck with a dinosaur. over 1 year ago

If you buy something yourself, I would go for a smartphone. Certainly Android is well supported here.

You can do more mapping stuff with a smartphone than with a navigation device. And they're becoming really cheap (to €100).

A car navigation device isn't any good for mapping, and hiking devices are a lot more expensive. Sure, they have a better build quality, but you don't need that when you're just mapping on the road.The GPS signal of expensive devices is also better than the signal of cheap devices, but aerial pictures can help you solve that problem.

(Not yet) 1000 addresses over 1 year ago

Great work. As you notice, you can do 100 in a day, so the number 1000 isn't something impossible to reach.

If you do it one day a week, you'll be done in less than 3 months. Quick isn't it?

Btw, you can see your stats at http://hdyc.neis-one.org/? (just fill in your user name). It looks like I have 5000 addresses added.

Newbie over 1 year ago

Welcome here. Don't be shy to edit the map. Just zoom to where you live and add anything you want (roads, pubs etc).

Also, if you want to introduce yourself to some more local mappers, or get local help, subscribe yourself to a local mailing list: http://wiki.openstreetmap.org/wiki/MailingLists (note that some might be busy, but you can always unsubscribe).

And be sure to check our wiki and your local project to see where to local community can get some help, and how you can do it: http://wiki.openstreetmap.org/wiki/Indonesia

Regards, Sander

New OSM-PH Logo over 1 year ago

The best local logo there is.

testen over 1 year ago

En, is de test gelukt?

De bedoeling van OSM is natuurlijk dat je de kaart aanpast. Als je niet weet hoe, dan kunnen we je gerust helpen (stuur een prive bericht, ik krijg geen meldingen van nieuwe comments).

Did a second edit to fix the errors in my first edit over 1 year ago

Hmm, using JOSM for your first edits. Watch out with that. JOSM is very powerful, as they say: "it gives you enough rope to hang yourself".

Maybe it's better to start with the online editor Potlatch, compare the defaults of Potlatch with the "advanced view". When you know enough tags as displayed in the advanced view, you can switch to JOSM, as it are those tags you need for JOSM.

If you just want to search for a tag for that one feature you can't map, use our wiki: http://wiki.openstreetmap.org/wiki/Main_Page

Thanks for the contributions btw. Names are definitely needed, as that's what we can't see from aerial pictures.

Correction sur carte velaux over 1 year ago

Bonjour Legueux,

bienvenue chez OSM. OSM est un projet cartographique complètement différent. Dans OSM, ce sont les utilisateurs qui créent la carte. Si vous allez voir la carte, vous pouvez appuyer "modifier" (ou quelque-chose comparable, dépendant de votre langue).

Dans la mode de modification, vous pouvez changez tout que vous voulez. Vous pouvez dessiner des nouvelles rues, vous pouvez sélecter une rue, et donner un nom. Ou tant d'autre choses.

Voir la guide complète ici: http://wiki.openstreetmap.org/wiki/FR:Beginners%27_guide

Merci en avant pour nous aider, Sander
