maps

I'm fairly new to JSON, and I'm trying to get the latitude and longitude of a geocoded city from the Google Maps API using curl. The function I'm using is: function geocode($city){ $cityclean = str_replace (" ", "+", $city); $details_url = "http://maps.googleapis.com/maps/api/geocode/json?address=" . $cityclean . "&sensor=false"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $details_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $geoloc = json_decode(curl_exec($ch), true); $step1 = $geoloc['results']; $step2 = $step1['geometry']; $coords = $step2['location']; print $coords['lat'];

How can I merge two STL maps into one? They both have the same key and value types ( map<string, string> ). If there is an overlap of the keys, I would like to give preference to one of the maps. jkerian Assuming you want to preserve the elements in mapA , and merge elements in mapB for which there is no key in mapA : mapA.insert(mapB.begin(), mapB.end()) will do what you want, I think. Working example: #include <iostream> #include <map> void printIt(std::map<int,int> m) { for(std::map<int,int>::iterator it=m.begin();it!=m.end();++it) std::cout << it->first<<":"<<it->second<<" "; std::cout <<

最近在做信息系统，需要根据坐标在地图上展示，做点记录，哈哈， 这东西看起来不错，有点不好的是ＩＥ6居然不支持／ 首先在ＡＳＰＸ页面中的ＨＥＡＤ中加入以下标记 View Code <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=true"></script> 增加以下JS代码 View Code <script type="text/javascript"> ///经纬度换成十进制数 var DegreeToDecimalDegree = function (sJWZB) { var aDSM = sJWZB.split("."); var

Using Google Maps API to add an infoWindow to each marker. Markers come from an array. Although, infoWindow only shows up for the first marker, not the others. Why? Thanks. function set_markers(array) { var mapOptions = { zoom: 13 } for (var i = 0; i < array.length; i++) { var single_location = array[i]; var myLatLng = new google.maps.LatLng(single_location[1], single_location[2]); var marker = new google.maps.Marker({ position: myLatLng, map: map, title: single_location[0] }); var infowindow = new google.maps.InfoWindow({ content: "" }); } google.maps.event.addListener(marker, 'click',

I am able to plot a map and caption a specific point: library(maps) map("state") text(-80.83,35.19,"Charlotte",cex=.6) I can also plot a circle centered around that point: symbols(-80.83,35.19,circles=2, add=TRUE) However, I would like to control the size of the circle. In particular, I want to draw a circle with a radius of 100 mile around multiple locations contained in a data.frame, matrix, or list. You can write a function to customize how you want the circle to look. For example: plotCircle <- function(x, y, r) { angles <- seq(0,2*pi,length.out=360) lines(r*cos(angles)+x,r*sin(angles)+y)

I have Android Map Extension attached under actionBar. I have couple of markers, lets say 2000. Than I have ArrayList of selected 3 markers upon some constant condition, nevermind. I want to zoom and move map to include this selected 3 markers at max possible zoom. It's an easy task, from this forum I found an easy way to do it : LatLngBounds bounds = new LatLngBounds.Builder().include(new LatLng(maxLat, maxLon)).include(new LatLng(minLat, minLon)).build(); mMap.moveCamera(CameraUpdateFactory.newLatLngBounds(bounds, 0)); I have map perfectly zoomed at this 3 markers. Now is hard part. When I
