maps

on the iPhone we have the Apple's amazing MapKit. There is something similar for Mac OS X? If possible something more advanced than a simple WebView, because I need that it manage automatically at least: annotations the user interaction the zoom in/out an overlay view (Even if the maps are not from Google is ok.) Thank you very much! Jason Medeiros Update 2 MapKit is available in OS X 10.9 Mavericks : Map Kit Framework Reference . Update - pulled from my comment below The situation has changed and there now exists a third party MapKit for Mac OS X. Find it at http://github.com/Oomph/MacMapKit

I am trying to plot a map with positive and negative values. All positive values should have red color while negative should have blue color and zero should have white just like in this sample plot with discrete colors Below is the code I'm using: library (rasterVis) ras1 <- raster(nrow=10,ncol=10) set.seed(1) ras1[] <- rchisq(df=10,n=10*10) ras2=ras1*(-1)/2 s <- stack(ras1,ras2) levelplot(s,par.settings=RdBuTheme()) Thanks very much for providing a general solution which can be applied in other mapping exercises as well. jbaums I wrote a gist to do this. It takes a trellis object generated by

I have put together a cities database from MaxMind and it includes the lat/lng values for each city in the database. I have also put together a map of North/America and I would like to have a icon appear on the x/y coordinates of the map which are derived from the lat/lng coordinates of the city database record. From my understanding I need to find the left/top bounds of the map first (lat/lng -> x/y) and then use that as a difference for the linear relationship between any of the north american city x/y coords. Finally, depending on the size of the map, its just a few simple division and

Given a latitude and longitude, what is the easiest way to find the name of the city and the US zip code of that location. (This is similar to https://stackoverflow.com/questions/23572/latitude-longitude-database , except I want to convert in the opposite direction.) Related question: Get street address at lat/long pair This is the web service to call. http://developer.yahoo.com/search/local/V2/localSearch.html This site has ok web services, but not exactly what you're asking for here. http://www.usps.com/webtools/ Any of the online services mentioned and their competitors offer "reverse

Is there a way I can dynamically add data to a map in javascript. A map.put(key,value) ? I am using the yui libraries for javascript, but didn't see anything there to support this. Well any Javascript object functions sort-of like a "map" randomObject['hello'] = 'world'; Typically people build simple objects for the purpose: var myMap = {}; // ... myMap[newKey] = newValue; edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do. 13 Feb 2014 —

I'm wondering if only by applying some standard algorithms is possible to write a short function which compare two std::map<string, string> and returns true if all the key-value (but some) pairs are true. For example, these two maps should be evaluated as equal map<string,string> m1, m2; m1["A"]="1"; m2["A"]="1"; m1["B"]="2"; m2["B"]="2"; m1["X"]="30"; m2["X"]="340"; m1["Y"]="53"; m2["Y"]="0"; Suppose that the two maps have same size and all their elements must be pairwise compared except the value stored by the key "X" and key "Y". A first attempt would be a very inefficient double nested for

So i try to achieve a result as on foursquare: https://foursquare.com/explore?cat=drinks&mode=url&near=Paris which is when you clik on a marker on the map, it scrolls through the listed of restaurants on the right -hand side of the screen to the ad hoc restaurant, and highlights it through CSS. Conversely, when you click on the restaurant on the list, it highlights it on the map. I am using skobbler/leaflet. I think I can achieve this by amending dynamically CSS as shown in this example: http://jsfiddle.net/gU4sw/7/ + a scroll to destination script already in place in the page. To achieve this
