问题 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 =

Assign ID to marker in leaflet

问题 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

How can I merge two STL maps?

旧街凉风 提交于 2019-11-28 16:57:00
问题 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. 回答1: 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>:

Iterating over Typescript Map

天大地大妈咪最大 提交于 2019-11-28 16:56:10
I'm trying to iterate over a typescript map but I keep getting errors and I could not find any solution yet for such a trivial problem. My code is: myMap : Map<string, boolean>; for(let key of myMap.keys()) { console.log(key); } And I get the Error: Type 'IterableIteratorShim<[string, boolean]>' is not an array type or a string type. Full Stack Trace: Error: Typescript found the following errors: /home/project/tmp/broccoli_type_script_compiler-input_base_path-q4GtzHgb.tmp/0/src/app/project/project-data.service.ts (21, 20): Type 'IterableIteratorShim<[string, boolean]>' is not an array type or

C++ map access discards qualifiers (const)

泄露秘密 提交于 2019-11-28 16:16:39
The following code says that passing the map as const into the operator[] method discards qualifiers: #include <iostream> #include <map> #include <string> using namespace std; class MapWrapper { public: const int &get_value(const int &key) const { return _map[key]; } private: map<int, int> _map; }; int main() { MapWrapper mw; cout << mw.get_value(42) << endl; return 0; } Is this because of the possible allocation that occurs on the map access? Can no functions with map accesses be declared const? MapWrapper.cpp:10: error: passing ‘const std::map<int, int, std::less<int>, std::allocator<std:

Open alternatives to Google-maps?

爱⌒轻易说出口 提交于 2019-11-28 15:49:25
问题 I'm looking for an alternative to Google-maps with all the richness of their API but more open. Does such a thing exist? 回答1: OpenStreetMap is, of course, the obvious answer. There are various APIs for managing the data in the database, and there are various APIs for getting maps onto your webpages, such as OpenLayers, Mapstraction, or Staticmaps. 回答2: Google have recently introduced a limit of 25,000 map sessions per day, which forced us to consider the alternatives for some of our sites.

Using custom map image tiles in LeafletJS?

北城以北 提交于 2019-11-28 15:16:22
Do my tiles need to adhere to any particular specs? I have a large image file which I'd like to turn into a map with LeafletJS. I am going to be using the Python Imaging Library to cut it up into all the various tiles I need. However, I can't find any information about using custom maps in Leaflet. Do I provide Leaflet with the range of X,Y,Z info somehow? Do I give it the pixel size of each tile? Does it figure this out on its own? To put my question into one concise question: What do I need to do in order to have image files that can double as map tiles with LeafletJS, and what, if anything,
