This is a followup to my previous question, for which I did receive responses, to help me to develop a better understanding of OpenStreetMap.

I want to post a screenshot saved as a jpeg image to a new diary entry, and attach an explanation of the problem illustrated in the screenshot. Is there any way to do this that doesn’t require posting to a third party application, then posting a link in the diary entry to the third party application?

I don’t have any third party applications that I can post the jpeg mage to, save Facebook. If I use Facebook, the link allows people to see other parts of my site; which isn’t acceptable.

I have a question to pose to the OSM contributors body regarding rendering of natural=wood areas, which I think would be better described with a screenshot of the rendered map.

I realize that OSM is powered by volunteer labour, and I highly appreciate it, I’d just like to find out how to get an answer to my question.

Specifically, some of the areas that I have tagged in the Alberni Valley as natural=wood, show up as dark green on the rendered map; whereas other, adjacent areas, with exactly the same tagging, do not show up as dark green but are essentially blank, nor do the labels attached the unrendered areas appear. If I could post a screen shot, this anomaly would be a lot easier to understand.

This problem has just recently appeared, and through no action of mine, as far as I know. I refer to the rendered map frequently, to view how my edits (using JOSM), appear.

Some people say, don’t map for the renderer, but aside from using the rendered map as a means to control my edits, I have numerous times shown the rendered map to others, to help them understand OSM, and perhaps be interested enough to become contributors. There are few people in the Alberni Region of Vancouver Island who are interested enough in contributing to make a concerted effort to upgrade the map, for the benefit of all users, and I would like to encourage others to become contributors. The rendered map is a valuable resource, and has to be considered a the final product.

When people see the extent of the resource extraction roads and other land use detail, current and otherwise, that show on the rendered map they are usually enthusiastic to have more such detail developed, and might possibly become contributors, or provide me with on the ground edits which I can incorporate using JOSM.

I expect there is a large number of technically oriented people, who use a variety of mapping applications, to produce specific maps for specific purposes, with OSM as a base, but that is not my objective. I am trying to develop a map focused on the Alberni Region of Vancouver Island which will help people to understand what the area is like, in terms of land use, and provide them with a guide for navigating, using OSM rendered maps, the many resource based roads in the Region. I expect to be able to simply refer them to the OpenStreetMap website and let them see for themselves the mainly industrial roads and openings in the forest, which define the land use in the Region. Anything more complicated will simply be self-defeating.

The ones that are no longer rendering have problems - If it is supposed to be a single way enclosing an area .. then the way is not ‘closed’ - there is at least one gap. Or the way crosses itself. If it is a relation then - the outer is not closed or crosses itself. Or an inner crosses the outer.

If you post the number of the way/relation .. or put a link to it like

way/173244595

then people can go and ‘look’ at it them selves with all the tagging and nodes etc and make specific comments on it.

See @imagico/diary/44711 for the reason why this happened.

There are many free hosting image websites, such as Imgur or TinyPic. Why don’t you use one of them?

Hi, if you have problems with image links, you also can just post the URL of the OSM map location, or the object specifically, that you want to show.
Examples:
map url: osm.org/#map=13/-27.6021/-48.5343
object utl: way/308237803

There is currently no method, unlike some other forum software, to upload a local image from your desktop to the server hosting these Diaries & then have it shown in a Diary. That is a damn shame since it would be a useful addition. However, until someone writes the routine, offers it as a suggestion, and an admin decides that yes, the code offered works, is usable & would be a good addition, that will not happen.

I have received some interesting and helpful comments on my post. Thanks to all. I shall look for breaks in the suspect polygons as a first step in resolving the problem.

While I do not understand the need for a screenshot other than as a snapshot at a particular point of time like right now where a new carto style means a mix of new, blank areas and older rendered areas, I was disappointed that none of the posted links take me to the actual area you see these problems.

However from your description, I believe you are referring to an area which might be around https://tools.geofabrik.de/osmi/?view=areas&lon=-124.70277&lat=49.22752&zoom=9&opacity=0.66 which you can see has a lot of problems preventing many woods from rendering.

You can also zoom in with Mapnik tiles to see the forests re-appearing at certain zoomlevels.

I took a look at a couple problem areas to see if a quick fix was posssible for this beginner, only to realise the logic behind the self-intersecting multipolygons was too much for me to perform a quickie fix, sad to say.
