Re: [OSM-talk] What do you wish you'd known?
I wish I'd known that you shouldn't ask the community for help to set up a team to develop something marvelous but DIY! Alone! You need to go sit in the basement, blind the windows, block IRC and e-mail, completely ignore the internet, sleep during the day (or better, don't sleep at all) and build something extremely smart you are sure everyone wants. Then after a few months when you finally come out; near blind, pale as the moon and showing symptoms of scurvy. You reach out and say Behold! O community of loyal fellas I am back! To donate my project as open source to you! Because I knew you would be waiting for it! Because I, and I alone am the greatest! And the community will burst out in tears of joy, embrace you, love you for ever and trust you to be its Saviour, they will signal the press who will be upon you with microphones, cameras and lots and lots of beautiful women will suddenly want to go out with you. You will be hired by some Larry, maybe a Sergey, or a Steve J or B and they will pay you millions! And you and your superior skills will make the world turn counterclockwise! Teamwork? Yeah right.. I am a University IT student. I don't need others, just bits and bytes and they will make me rich! I don't care if my source is open or closed, I care about me! I don't care if code would get better if I collaborated, no code can be better then mine, no one else can understand the excellence of it!

SteveC st...@asklater.com wrote: What are the thing or things you know know that you wish you'd known when you started with OpenStreetMap? The most annoying thing, I wish I had known before is, that editors destroy things without any warning, but you do not have the chance, to take notice of that fact. I.e. potlatch destroys the correct order of the ways in a route relation, i.e. if you divide a way into two parts. And you do not have the chance to take notice, because potlatch does not show the order of the ways in the relation. Further you are not able to notice, that changing the direction of a way destroys a route relation, because in this case the direction of this way is not changed in the relation automatically. These are only two examples of many more. Warnings concerning these facts are not brought up in the description and videos for beginners. Thus I destroyed many relations by making basic and alleged harmless editings, until another user told me. Fortunately he was creator and the maintainer of these relations and the user of another editor. So he could take notice of my destroying. Otherwise I would have gone on. And thus I wish I had known this before. And today I find other users destroying relations. Possibly they wish, they had known it before, too. The problem is, that you cannot distinguish, whether the user is the problem or the editor: Cause there are many new editors on the road, i.e. for smartphones. These editors need registration. You cannot edit with your OSM-account. That means, you need many registrations in order to test these editors. Possibly some of the editors in future will cost money. Thus without all these accounts and paying money you cannot distinguish, whether the user slips up or the editor. Off topic: As far as I know, everybody is allowed to offer a new editor. If their number will grow and destroy the OSM-data as shown above, the maintainers could lose interest and thus the quality of OSM-data decrease. Possibly there should be some considerations, how the unwanted damage of the data by the editor-software could be avoided in general.

Because this is not possible i.e for an e-road with about 5000 km length, people set up projects in the wiki in order to establish this relation within month' and years as teamwork. The same applies i.e. to the public transport net, which is collected in many towns nearly complete, the relations of motorways, national- and other referenced roads, the borders of towns and suburbs, by relation splitted lanes of multilane roads with left-turn, right-turn-function etc etc. One of the most important advantages of the cycle- and hiking-map are the routes, which are long in many cases as well. With destroyed routes these maps lose much of their sense of exist. And all these routes can be destroyed within seconds by harmless editings and shoot down this long lasting work within seconds. Cause it is really hard, i.e. to insert a short OSM-way (misleaded by the editor-software) at the correct position of the relation, if you do not have excellent knowledge 1) of the object and 2) of every place in detail. Try it and you know, what I mean. That means, you have to wait for a person that has both and finds this dispersed way. And that could last very long. If the one, who established the route possibly in a rurely area, does not come back, the chances are good lasting years. If one founds this mistake in his home-area, he has no chance to heal it, if he has no clue i.e. from this bycycle-route or the public-transport. In the case of navigation systems, their users could be misguided because of such harmless editings. I.e. in case of a destroyed left-turn-lane-relation you have to Go straight ahead!

hi What are the thing or things you know know that you wish you'd known when you started with OpenStreetMap? I use the OSM tiles to teach javascript. 2 for loops for x,y and absolute positioning delivers a big map. That's cool. For moving the map there are mouse events nessessary. And i can teach the mouse events. But than it switches to a completely different coordinate system. To use webservices that gives wgs84 from a place name is easy. But how to do the gps to xy transformations? I found some really nice formulas in the wiki, but it took a year or two until I found it. At the moment I search a bounds to center+zoom formula (no easy). I think I have seen it in the wiki, but can't find it anymore.

What are the thing or things you know know that you wish you'd known when you started with OpenStreetMap? * That the wiki is not the standard for tagging information. It evens says so but at the same time people still often refer to it and treat it as the reference documentation for OpenStreetMap. * That the tags you use really don't matter that much as long as a human can interpret what you meant, don't spend hours or days researching. If you can't find a suitable tag in a matter of minutes just invent a new one. * That the editor you see when you click edit is called Potlatch. I know it says so but I missed that. * That you can change your user name later. Signing up for new services I always have to decide whether to use some anonymous handle or my real name so it is very nice to sign up anonymously and later change my mind. * WTF is this Mapnik or Osmarender? Cycle Map (and No Name to some extent) is a descriptive name. Mapnik and Osmarender are not and I didn't care at all which tool was used to render the map * That I can use Shift + Mouse to zoom in to a specific area * That the forum (as opposed to the Wiki) uses the OpenStreetMap login data * That almost all discussions on the mailing list degenerate into some off-topic crap without the participants having the decency/foresight to change the subject * The tag voting procedures on the wiki don't really mean anything * There are other editors. I'd liked something like the new browser chooser for Windows. When you first click Edit you are presented with four/five editors (josm, merkaartor, mapzen, potlatch ...) and a text like If you just want to get started now you can use our Flash based editor Potlatch here * I'd have liked to know about OpenStreetBugs (and today about KeepRight, OSM Inspector and other QA tools) as well as tagwatch (well today tagstat would probably be better or osmdoc if it ever gets fresh data ;-) ) and OpenRouteService/yournavigation Remember...these are from my very first days with OSM.
