[When] about 1 month ago [Comment] the main way is to suck in all the data for series of bounding boxes that cover the site in question then use sort process (often linked to renderstyling files like Mapcss and ealy xml stylesheets. these rejct everything you don't tell them to map in the render (mapcss can in advanceced use not only drill down but do both computation on varibles stored in tags and plot multiple line and area features {see the road lane stylesheet add-on option of a multilane highway to see it rendered with dashed line between each lane on a route widenend to meet the number of lanes}. MapCSS can in most systems if study yhte advance guides work with nested relations withen boolean equations of different tags). So it shouldn't be too hard with some systems to avoid roads and airports if that is a bit unhelpful complex and reliant on others work you could try a data appoch and treat the xml datafile in a spreadsheet or text editior to sort thourgh using find and replace. If you you have too much to do I not the odd course now and then and need something quicker for baulk work then try reasuching the likes of gawk/awk, grep, perl and other text pocessing systems oftern originating on unix machines but are now availble from some place for a lot of the other popular platforms like MS-Windows, Risc-OS and different types of the Mac-OS's (pre & post X) etc. Ihope this might be useful.
