Hello List,
Either I have found a memory leak or I am doing something wrong(most
likely). In our application we have about 1000 markers, these change on a
regular basis. I haven''t found a way to search the markers to only
change
the markers that have changed state, so every time one marker needs to be
updated, all the markers get redrawn. Now I have provided a test
case, below, so you can see what I have done wrong. I have tried this with
Chrome, IE(8.0), FireFox(3.0) and Safari(4.0) and when it is loaded the
browser memory usage keeps growing.
Thanks in advance,
Craig Spry

Thanks for the report Craig. I know there were some bugs in the first version of Mapstraction. We''re building out Mapstraction v2 - (and it''s being used in production sites) so that would be my first suggestion to try. You can download it from: http://code.google.com/p/mapstraction/ And here is an example: http://code.google.com/p/mapstraction/source/browse/trunk/examples/index.html The API itself is the same - you primarily just need to change the include files. Let us know how that goes.

We use http://www.openstreetmap.org/ as our source for maps and looking at what you have in v2, it doesn''t look like the open street maps and/or open layers has been implemented yet, is this right or have I missed something?

Hi Craig, you are correct v2 doesn''t yet support openstreetmap. One issue here is that (to my knowledge - please correct me if I''m wrong) there is no OSM javascript library for embedding maps in pages. In the past we''ve done it by using the Google javascript and adding OSM as a tile layer. This works, but has the downside of meaning you need to display a Google logo since you''re using their code. So it''s a bit confusing to users as to whether they are getting an OSM or a Google map. 2 options for you 1. use Cloudmade, which is OSM data rendered by Cloudmade - see http://cloudmade.com 2. help add support for OSM. My only other comment, as someone who''s active in OSM, would be that OSM, due to it''s volunteer nature, doesn''t provide any sort of SLA. A few weeks ago for example the OSM site was down for 2 days due to maintenance. Whether or not that''s a problem for you I guess depends on the nature of the service you''re building. good luck and thanks for your help On Wed, Sep 2, 2009 at 06:27, Craig Spry <craig.spry at gmail.com> wrote:> We use http://www.openstreetmap.org/ as our source for maps and looking at > what you have in v2, it doesn''t look like the open street maps and/or open > layers has been implemented yet, is this right or have I missed something? > Regards, > Craig Spry > > On Wed, Sep 2, 2009 at 12:30 PM, Andrew Turner <andrew at highearthorbit.com>wrote: > >> Thanks for the report Craig.

It should be straight-forward to add OpenLayers provider. Also - as Ed mentions, CloudMade support is already in v2.> > 2 options for you > 1. use Cloudmade, which is OSM data rendered by Cloudmade - see > http://cloudmade.com > 2. help add support for OSM. > > My only other comment, as someone who''s active in OSM, would be that OSM, > due to it''s volunteer nature, doesn''t provide any sort of SLA.

I think I might do an OpenLayers provider, I''ll see if I can get some time to do it over the weekend, if I manage to do it I will contribute it so other people can use it.

Just out of interest - have you tried running that code directly on the OpenLayers API?

I don''t want to use cloudmade because I need a key even for local files. I need to use an api without key for local files. I don''t use the maps in a web site. I includes webkit in a python program in which I can see maps used for genealogy. Google, Yahoo, Microsoft and Openlayers permit this functionality. I understand in v1 openstreemap confused peoples when we saw the google logo, but it worked. I''m too busy with gramps and don''t know sufficient javascript to help you.

I have to second Serge. Today I wanted to switch from mapstraction v1 to v2 and noticed that the "openstreetmap via google" provider hasn''t made it into v2. I regret this, because I want to offer google, microsoft and openstreetmap maps in my app and now I have to embed and configure 3 javascript apis instead of 2. It also means more legal difficulties/costs (I don''t know the terms of service of cloudmade, but I suppose it is non-free for commercial purposes). on the other side, the development of mapstraction v1 seems to be ceased. Quick conclusion: any hints how to re-enable the openstreetmap support in the mxn.google.js?
