I need to delete several things on a map, such as subways and parking lots, in order to save it as a new map (customized). I wonder if deleting these items, I am modifying the general map, since I do not want to harm the other users. Thank you in advance! Lucy

If you delete anything in OpenStreetMap, yes, you're deleting it for everyone. If you want to customize a map for yourself, download the data and make the adjustments in the downloaded data. QGIS has a great OSM plugin.

Also note that if you want a map rendered with/without some type of data (for exemple, no subway), it's certainly better to change the renderer settings than to delete data and re-render. See your renderer's documentation for this.

You could also export the map as SVG and then delete certain objects you don't like using a SVG editor like Inkscape.

The XAPI interfaces can help you pull the elements you want to keep without affecting the live map.

If you want a map with some extra things shown or some things missing you could try rendering it for yourself. Try Maperative http://maperitive.net/ for your own personalised map.

Here is a post about how to use Maperitive. It doesn't tell you how to customize the style but it should get you rendering a map quickly. The styles are just text files that you can probably figure out if all you're doing is removing things. http://ksmapper.blogspot.com/2011/08/simple-openstreetmap-tile-rendering.html

It depends on what you're calling "deleting". If you download a set of data in josm, and delete some data. Your modifications doesn't impact the central OSM base until you send your modifications. So, you can download some data with JOSM (or qgis, or merkator, …), edit what you want, don't send your data but save them in a file, and then use them for whatever you want (that I don't know indeed).
