Plotting lines on map - gcIntermediate

由 元气小坏坏 提交于 2019-12-01 08:29:02
问题 My code works well to produce a map and lines from point A to point B, however for countries in the far eastern hemisphere, the line attempts to cross the shortest path (e.g. east from Australia) and breaks to create a straight line across the plot. Any suggestions? I shortened the code and included it all below to play with. There was mention (in the link in the code) of using greatCircle, but I could not get this to work. Thanks! adds <- c("Argentina", "Australia", "Germany", "Japan",

Google Maps infoWindow without marker?

由 有些话、适合烂在心里 提交于 2019-12-01 07:43:58
According to the documention a marker is optional with an infoWindow, so how is this achieved please? I have tried infowindow.open(map) and infowindow.open(map,null) but both produce nothing. infowindow.open(map) makes no sense since you need to specify the position where the infowindow should open, also it has a tapered stem which specifies the location where it should point. According to the documentation of Infowindows- InfoWindows may be attached to either Marker objects (in which case their position is based on the marker's location) or on the map itself at a specified LatLng. So if you

D3 - Large GeoJSON File does not show draw map properly using projections

由 我是研究僧i 提交于 2019-12-01 07:31:14
问题 I am having an issue with drawing this GeoJSON file I picked up from data.seattle.gov. Specifically, I'm using the Shape file which can be found here. I converted it to a GeoJSON file where I provided a small sample below. By using D3, I was hoping to draw out what should be the different precincts in Seattle (actually I'm not entirely sure what it should be which is why I'm drawing it... ha...) but for some reason it isn't showing it correctly despite the fact that the paths are correctly

Get position of map area(html)?

由 扶醉桌前 提交于 2019-12-01 06:47:37
问题 Is this possible? I'm trying to find the x and y coordinates of the element in relation to the browser . var position = $(this).position(); x = position.left; y = position.right; Doesn't work. Is there any way to do this? http://adamsaewitz.com/housing/ highlight the blue room 070 回答1: Edit for updated question: Since you're using <area> it's a different story, and fetching from the coords attribute is much easier, like this: var position = $(this).attr('coords').split(','); x = +position[0]

When pattern matching maps in Erlang, why is this variable unbound?

由 和自甴很熟 提交于 2019-12-01 06:04:16
-module(count). -export([count/1]). count(L) when is_list(L) -> do_count(L, #{}); count(_) -> error(badarg). do_count([], Acc) -> Acc; do_count([H|T], #{}) -> do_count(T, #{ H => 1 }); do_count([H|T], Acc = #{ H := C }) -> do_count(T, Acc#{ H := C + 1}); do_count([H|T], Acc) -> do_count(T, Acc#{ H => 1 }). In this example, the third clause where the map key "H" exists and has a count associated with it, will not compile. The compiler complains: count.erl:11: variable 'H' is unbound Why is H unbound? This works by the way: do_count([], Acc) -> Acc; do_count([H|T], Acc) -> do_count(T, maps

Calculating MAX and MIN Latitude and Longitude with distance from Location - Objective C

由 拟墨画扇 提交于 2019-12-01 05:51:15
I need to compute MAX and MIN Latitude and Longitude values from a location with certain distance. I have thousands of locations stored in CoreData, and I want to show only the ones within 5km from users location. How can I approach this problem? Here's a possible solution: macros to convert Degrees to Radians #define deg2rad(degrees) ((degrees) / 180.0 M_PI) macros to hold my searching distance #define searchDistance 5.00 //float value in KM set the minimum and maximum Latitude, Longitude values float minLat = userLocation.coordinate.latitude - (searchDistance / 69); float maxLat =

jQuery and Google Maps json response

I am having troubles getting geo location info from google maps api the code is pretty straight forward $.ajax({ type: "GET", cache: false, url: "http://maps.googleapis.com/maps/api/geocode/json", dataType: "jsonp", data: { address: "Ljubljana " + "Slovenia", sensor: "false" }, jsonpCallback:'json_response', success: function(data) { top.console.debug(data); $('#location_setter').dialog('close'); }, error: function() { alert("Error."); } }); function json_response(data){ alert("works"); } I always get an error back. I tried directly too (I read somewhere that the callback should be set at the

Add Points to Choropleth Map in ggplot2

I've tried:
