I'd like to iterate over a std::map using BOOST_FOREACH and edit the values. I can't quite get it. typedef std::pair<int, int> IdSizePair_t; std::map<int,int> mmap; mmap[1] = 1; mmap[2] = 2; mmap[3] = 3; BOOST_FOREACH( IdSizePair_t i, mmap ) i.second++; // mmap should contain {2,3,4} here Of course this doesn't change anything...
Hi forum. Playing around with Google Maps these days, with some directions. I have a map that gets the directions and address (reverse-geocoding) when dragging and dropping the markers. If there is two nodes on the map (http://dev.korebogen.dk/gmap/) the script is working fine (click set directions) - but I need to add a click event s...

I need to write a small snippet of code where I need to check contents of a map (key value) if it exists in another map , remove it from the map E.g Map1: 1=>obj1 2=>obj21 3=>obj3 4=>obj4 Other map Map2: 10=>obj10 20=>obj20 2=>obj2 30=>obj30 3=>obj3 The result of fun (Map1, Map2) after it executes it has the following ouput ...
When a marker is placed, I want to call a php function (in another file) with the latitude and longitude as input and output the result in a div on the page. So whenever the marker is moved, it updates the div with the latest result of the function. I know I'd need javascript to do this but I'm not very familiar with it and any help wou...
Here is what I am trying to do. I have about 160 places of interest. The user enters their address (postcode, full address, whatever) which I use Google to geo-encode. I then create a Google map centred about this point and I add a marker for each of my points of interest to the map (using a MarkerManager). So far so good. I want to dis...

Ok so basically I am talking with someone about building a way for users to post locations to a map and have a pin over the location. I know Google Maps can do this and probably has the best documentation/support. I was just wondering if/what other options there are. I have found Pushpin and Mappy but I really don't know much about ei...

Is it possible and effectively divide 30k (and growing) or more coordinates into tiles on Google Maps? My goal is to index all coordinates - assign to a tile and than define a tile size for each zoom level. On the client side marker manager will do the clustering for each tile (which ideally would have less than 200 points) New coordi...
Hello! At first I want to say: I couldn't find a support forum for this library so I would like to try it here. I hope such questions are allowed here and the link to my page needn't be removed. The link is only for seeing how it works and which parts don't work. Please don't remove it. Now to the question :) I want to use the library...

So I'm writing a Java app, and I've got an ESRI Shapefile which contains the borders of all the U.S. states. What I need is to be able to determine whether any given lat/lon point is within a specified distance from ANY state border line - i.e., I will not be specifying a particular border line, just need to see whether the point is clo...
I am currently using the google maps' reverse geocoding API to convert long/lat received from an iPhone's CoreLocation API into city/state information on a google app engine server. Would this be considered a violation of the terms? I've done some research and cannot find a direct answer to this question. Right now, we will be distrib...
Is there a way to embed/mashup the OpenStreetMap in your page (like the way Google Maps API works)? I need to show a map inside my page with some markers and allow dragging/zooming around, maybe routing. I suspect there would be some Javascript API for this, but I can't seem to find it. Searching gets me an API for access to raw map da...
