Phonegap - Open Navigation Directions in Apple Maps App

由 荒凉一梦 提交于 2019-12-18 03:33:35
问题 I have two variables - Destination and Source - and, using Phonegap, I'm trying to use jQuery to open the external iPhone Apple Maps app with directions. The code I'm using looks like this: var url = 'http://maps.apple.com/?q=daddr='+destination+'&saddr='+source; window.location = url; Whenever I click the relevant button however, it opens a new view in-app with Google directions as a webview, and I cannot return to the original app. How can link be opened instead with the iOS default map

android maps: how to determine map center after a drag has been completed

由 拟墨画扇 提交于 2019-12-18 02:51:00
问题 Is there a way through the android maps API, where I can detect the map center after pan animation has completed? I want to use this information to load markers from a server dynamically. Thanks BD 回答1: I also have been looking for a "did end drag" solution that detects the map center at the moment exactly after the map ended moving. I haven't found it, so I've made this simple implementation that did work fine: private class MyMapView extends MapView { private GeoPoint lastMapCenter; private

Voronoi diagram polygons enclosed in geographic borders

由 自古美人都是妖i 提交于 2019-12-17 22:50:57
问题 I am trying to create Voronoi polygons (aka Dirichlet tessellations or Thiessen polygons) within a fixed geographic region for a set of points. However, I am having trouble finding a method in R that will bound the polygons within the map borders. My main goal is to get accurate area calculations (not simply to produce a visual plot). For example, the following visually communicates what I'm trying to achieve: library(maps) library(deldir) data(countyMapEnv) counties <- map('county', c(

问题 I'm trying to create a nyc map with zipcode areas I can color in based on census data (like color an area red if majority white or blue if majority nonwhite). I am simply using one of the shape files I found online from here ( https://data.cityofnewyork.us/Business/Zip-Code-Boundaries/i8iw-xf4u/data ). I converted the shp file to a geojson and then a topojson file. I'd appreciate it if someone could look at my code below, and let me know how I can go about doing this. Code: <!DOCTYPE html>
