|Mapping in Thailand||about 1 year ago||
About that reservoir: The outer perimeter should be split into sections of less than 1900 nodes and be part of a relation and defined as "outer". The islands should be mapped as islets and include other attributes such as "scrub" and be defined as "inner" within that same relation-number! Quite easy really.
Next comment from me is that OSM is much more than a road map. Obviously in many parts of the world the priority must be on motorways, highways, roads, tracks and paths in that order. For example, it is also about POIs and their attributes with make daily life easier.
But, just for fun, take a look at:
for what is possible!

To amm and ToeBee.
Thank you both for being so responsive!
I looked at the solutions suggested (using API) and downloaded the area in question. Using http://www.jsoneditoronline.org/ I could browse the pertinent data but I could see how I could this in a useful way. Obviously it is my lack of the required skills that is hampering my efforts.
Do you think that is worth the effort to post a JOSM ticket?

|Learning about paths||about 1 year ago||
Your not the only one. In my humble opinion paths are narrow tracks, fit only for walking, going through the countryside. Footways and cycleways are for towns. We do have highway=pedestrian which can be a way or an area=yes. To any of these you can you can add attributes such as: bicycle=yes/no foot=yes/no horse=yes/no hgv=yes/ no etc. etc. many other restrictions can apply.
Having said that, Map Features recommends highway=path, bicycle yes, foot yes segregated=yes/no even in towns.
If you look around the OSM-world you will find many different opinions so it might be advisable to see what the prevailing method(s) are in your area of influence. If you are like me you will want to get on well with your local contributors.
|New contributor experience||over 1 year ago||
I like your perseverance. You will be a good contributor to OSM. Yes, OSM has a very steep learning curve and only those who read and understand the instructions will be excellent contributors. Even then you will still make mistakes as we all do but most of them come naturally from beginners. Don't worry about them though and ask for help whenever you need it. And be careful when correcting the work of others: You may not initially see the relations, multipolygons, turn restrictions, routes, etc. and change them. Many of my complex work has been eliminated, wrongly changed. I have come to expect it as being normal and it is equally important to keep enthusiastic newbies. You are very, very welcome.
There are a number of error-check applications that I use to check my work (and that of others). Check them out. Examples:
Studying these errors illustrates the errors that we all make. So don't forget: People that contribute a lot make a lot of mistakes. People who contribute less make fewer mistakes. But if you contribute nothing then you make no mistakes. So olease make a lot of mistakes!

Requirements: No special requirements
OS: Windows XP/Vista/7/8
Step 1: Download Setup File Step 2: Click "Run" or "Save File" in Firefox Step 3: Click "Run" once more Step 4: Easy installation will begin
The instruction says no special requirements but step 2 uses Firefox. I don't use Firefox (I use Chrome). Will it then work with other browsers?

I was unaware of OSM2World so thank you for this information. Yes it is equally well worth a mention.

Bernard has given a big hidden hint: Graduate to JOSM asap for easier editing. The learning curve is much higher but it is worth it and it is more fun. Ask advice from Bernard, I am sure he will assist you if you need it. I would too!
|multiple buildings at a Gutshof||over 1 year ago||
@BCNorwich I can't see the need for a moltipolygon relation. I have sent ConEbt a separate mail with other suggestions. If he takes you up on the help ask him to send you a copy of my humble opinion.
|Making OSM data mor compact||over 1 year ago||
Doesn't anybody read the relation:multipolygon instruction page.
Here is an extract:
The intended use of multipolygons is this:
Tags describing the multipolygon (e.g., landuse=forest) should go on the relation. The outer way(s) should be left untagged, unless they describe something in their own right. For example, a forest could be delineated by four roads, in which case the four ways would be tagged with the highway tag, but could still be used as "outer" members of the forest relation.
==== End extract
This clearly states that the outer perimeter of a multipolygon can share its nodes (i.e. they are merge) with roads. Therefore, in this case, at least half of the road on which the road runs is defined as landuse=forest.
Surely we should expect the renderers to understand this and act accordingly and this they do very well.
I have no difficulty editing such geometrical contructions. The difficulty lies in correcting the poorly documentated data usually entered by newbies using Potlach.

|How many contributors does OSM have?||over 1 year ago||
This is the first sensible statistic showing registered user against contributors that I have seen up to now, and I thank you for it: Well done! What would be nice to know is how many registered users are, well just that: Users that produce maps etc. And what about the back-room boys that keep this complex system going: How many are there? Where are they? We contributors are worthless without these brilliant people. You all have my greatest respect. Thank-you
|Getting started...||over 1 year ago||
It is an excellent way to start. SLOWLY. OSM looks easy but it is not so. Along the way you will find all sorts of complicated geometrical constructions that you'll only learn with time=experience. It is fun though! Check your work with KeepRight and OSMI. Best of all: Download JOSM and forget Potlach

This is dependant on your device.
For Android I use OSMAnd+
There are other available: Search the Wiki.
|Stuck with a dinosaur.||almost 2 years ago||
I have a Samsung Galaxy S GT 19000 bought two years ago with the notion of using it also as a tracker. It requires inputs from three sources to work as a GPS device: Signals from the phone provider, the GPS-Satellites, and local WLAN transmitters/Receivers. The consequence is that it reasonably works in areas of high population and along the motorway. It does not work in a reasonable manner in any other type of area; e.g. forests, hills, or any countryside where the above three signal sources are partially unavailable.
Note: I was comparing my Samsung with my friend's iPhone 3 at the time. It was worse than the Samsung.
My Samsung does become useful for OSM purposes when I use OSMAnd+ but that is another story.
For OSM tracking I have a Garmin GPSmap 60CSx from 2008 and it is very accurate in most cases. It probably still is one of the better models for OSM data collection. Unfortunately the ideal GPS device for OSM has yet to be developed. One with an integrated camera and a voice recorder. (There is one Garmin device with an integrated camera available).
You may be able to buy a second-hand GPS device on eBay.
You can always use walking-papers. I do!
|Es könnte alles so perfekt sein...||almost 2 years ago||
Wahrscheinlich nie. Begrundung: Neulinge können nicht sofort mit JOSM oder änliches anfangen.
Stimmt: Aber liegt das an Potlach oder fehlende Erfahrung?
Stimmt auch: Bei mir sind ganze relations vernichtet worden. Man kann auch nicht erwarten das ein Anfänger die Konzepte von Relations und Multipolygons versteht. Eigentlich musste Anfänger eine Art Schulung durchlaufen bevor sie komplexe geometrischen Formen ändern darf.
Ob ein Diskussion gibt weiß ich nicht: Stelle die Frage in "the help centre"
Bitte mein Deutsch zu entschuldigen.

|Yorkshire to Cyprus||almost 2 years ago||
Have a nice time in Cyprus: Perhaps you could try and fill in some of the gaps in the E4 Europeon Long Distance Path:
As you say there is a lot to do in Cyprus but don't forget: Your on holiday!
Hint: You can get free and good maps from the Cyprus Tourism Organisation: You have to ask for them as they are not on display!
I have entered a couple of their locations in OSM but there are many more not yet mapped but you can find their locations by googling

|Tracks||almost 2 years ago||
Ich habe ein Samsung GT-I19000 Galaxy. Vor 2 Jahren war es die Flagschiff Modell von Samsung.
Ich habe auch ein Garmin GPSmap 60Csx von 2008. Damals Flagschiff Modell von Garmin.
Meine Erfahrung entspricht das was stanton sagt. Mein Samsung kann ich nicht verwenden in Wald, Berge oder offene Landschaft, weder für navigation oder tracking.
Allerding es funktioniert als Navi entlang der Autobahn und für Orientierung innerhalb Städte.
Was ich jetzt sage ist nur Vermütungen.
Zwecks Festlegung der Coordinaten braucht Samsung drei Quellen;
In Wald und Berge sind oft 1, und 2. nicht vorhanden und der GPS Signal kann allein nicht mittels der integrierte Technology korrekt ausgewertet werden. Ich schätze das die Antenne und Auswertungslogik unzureichend sind. Sonst hätte Samsung auf 1. und 2. verzichtet.
Städte und Autobahn Es sind ausreichenden 1. und 2. Quellen vorhanden. Hiermit weißt dein Gerät innerhalb wenige Meter (sagen wir +/- 50 Meter) wo du bist. Die schwache GPS-Signal ist also ausreichend.
Nur zur Vergleich: Ein Garmin Navi wie der 60Csx ist am genauesten
a. In offene Gelände ) +/- 3 Meter oder besser.
b. In Wald meistens +/- 4 Meter
c. In Berge meistens +/- 10 Meter
d. In Städte leider nicht so gut. Hängt von Gebäudetyp / Höhe usw. Glass reflektiert Signale. Aber ausreichend.
