That is actually the same server. Yes including the ichosted, it is just a proxy.

12 connections is still 10 more than we allow according to our policy.

Created Issue: Set Connection Limit and use own User-Agent when connecting to OpenStreetMap [15971]

Please set the required max 2 simultaneous connection limit (from your current 50) and use a non-faked distinct User-Agent when connecting to OpenStreetMap.org

OpenStreetMap has a tile usage policy: http://wiki.openstreetmap.org/wiki/Tile_usage_policy

We run a friendly tile usage policy by you are abusing the situation.

Hi radioman,

Thanks for this great control, but I was also wondering about the lack of anti-aliasing for markers etc. How can I fix this?

Come guys, please play friendly. OpenStreetMap is an Open Source project with very limited resources.

The project can NOT sustain bulk downloading. Please limit the number of concurrent connection to 2 (Instead of 50!) and limit the amount of data that can be downloaded.

Use a genuine User-Agent and kindly block faking the User-Agent when accessing OpenStreetMap.

Hey and invite your users to improve our great map.

Please don't do that.

http://munin.openstreetmap.org/openstreetmap/yevaud.openstreetmap.html#Mod_tile - this shows the effect of the targeted block

The dip from 18:00 to 19:00 or so today was the effect of this block.

These are voulanteer run servers, on donated hosting, and cannot support some of the uses that some applications are trying to do - for

example downloading large areas of the map rapidly, without _lots_ more hardware and software effort. The servers are on a donated

100mbit connection - and they are nearly saturating this at times.

If you need large areas of the map for your application, then you need to either render them yourself from downloaded map data - or work out some other method.

http://wiki.openstreetmap.org/wiki/Tile_usage_policy

It's also possible that greatmaps has been inadvertently affected by the block, and was not teh targeted app.

The block was put up so that users of the app would get in contact, as the app was not identifying itself, and was downloading lots of tiles.

There was no other way to work out which app it was.

The right way is for the dev to pop over to the IRC channel - or post on the mailing lists.

Hi,

I got this message today, when I used the control, any idea what the problem is; I've been using it ok for the last few months, and my IP is not fixed.

there is overlay support already, if you mean something else, let's define it ;}

hi,

is there a possibility to create a function of overlaying one or more layers over the map?

Finally I found the solution. Here I want to share to all:

1. In GMapMarker.cs, add the following virtual function:

public virtual bool LocalPointInPolygon(Point p)
      {
          return false;
      }

2. In GMapControl.cs, in the function protected override void OnMouseMove(MouseEventArgs e)

change this line -- if (m.LocalArea.Contains(e.X, e.Y) to the following

if (m.LocalArea.Contains(e.X, e.Y) || m.LocalPointInPolygon(e.Location))

3. In the custom marker file GMapMarkerPolygon.cs, add the following function:

public override bool LocalPointInPolygon(Point p)
      {
          if (_localPoints == null) return false;

          int i, j = _localPoints.Count - 1;
          bool oddNodes = false;

          double ret;

          for (i = 0; i < _localPoints.Count; i++)
          {
              if (_localPoints[i].Y < p.Y && _localPoints[j].Y >= p.Y
                || _localPoints[j].Y < p.Y && _localPoints[i].Y >= p.Y)
              {
                  ret=_localPoints[i].X + (p.Y - _localPoints[i].Y) / (_localPoints[j].Y - _localPoints[i].Y) * (_localPoints[j].X - _localPoints[i].X);
                  if (ret < p.X)
                  {
                      oddNodes = !oddNodes;
                  }
              }
              j = i;
          }
          return oddNodes;
      }

Here I want to give thanks to Darel Rex Finley that provides the algorithm of detecting point inside a polygon in the following website:

it depends how you draw the marker, check red rect demo

Hi Heru,

very glad to know you can trigger the mouseover event when mouse is over polygons.

Can you provide some code how to do so?

Actually I am using C# to implement but I can understand Visual Basic 2008 very well.

Thank you very much.

Terence

Hello,

I am finetuning my application now. But can't get the marker "on mouseclick" (a downpointing arrow png file) at the right position.

Whatever I fill-in in the offset the marker is never placed in the right position. I have tried different zoomlevels, but that doens't make any diffrence.

The point of the arrow should be my right position (the bottom-center).

Any suggestion, idea??

Heru
