Implement Google 3D maps for my Android app?

牧云@^-^@ 提交于 2019-12-06 14:51:51
is it possible to use the new Google 3D Maps for Android in my app? I'm developing an app and I want to add this. thanx! http://www.google.com/mobile/maps/3d/ We have created this one: Nutiteq 3D Maps SDK . This is a SDK, not application, so you can use it in your apps as replacement of Google Maps SDK. You can't. The Google Maps application no longer uses the same SDK MapView that we third-party developers use. Someday, perhaps they will update it, and then 3D maps will be possible, but not as of today. Sorry! UPDATE Maps V2 allows 3D views, via camera tilt, if you are in a location that

I have a 2D footprint result for an eddy-covariance system on a 1100*1100 square meter, with the domain of domain = c(-100,1000,-100, 1000) the cell size of the domain (each grid) is 2 meters with the origin (0,0) accordingly on this location: Lon = -97.191391 #longtitude Lat = 36.055935 #latitude An example data (9.01 Mb) is attached here. FFP.rds then I can plot a Bing map on my site as this: library(OpenStreetMap) library(rgdal) map <- openmap(c(36.05778,-97.19250), c(36.05444,-97.18861),type='bing') plot(map) and I use image.plot() from package "fields" to plot the footprint with these

How to create auto-scalling image lying on WP8 maps

I am trying to add multiple pushpins to the map, that disappear when you zoom out enough, to make the pushpins so little, that they are not rendered anymore. I managed to achieve this effect with the following code: MapPolygon shape = new MapPolygon(); GeoCoordinateCollection boundingLocations = CreateCircle(geoCoordinate, 0.1); shape.Path = boundingLocations; shape.FillColor = Color.FromArgb(0x55, 0xFF, 0xFF, 0x00); shape.StrokeColor = Color.FromArgb(0xFF, 0xFF, 0x00, 0xFF); shape.StrokeThickness = 4; mapToDrawOn.MapElements.Add(shape); But what I really want to do is fill the polygon with a

How to sort both key and value in a multimap?

醉酒当歌 提交于 2019-12-06 13:52:17
问题 Suggest any method to sort a multimap for both key and its values. For example- Input- (5,1), (1,9), (1,1), (5,2), (1,2) And the Output must be- (1,1), (1,2), (1,9), (5,1), (5,2). 回答1: The answer is emplace_hint. Pseudo code will look like that:- insert_with_hint(M mmap, K key, V Value) { auto i1 = mmap.equal_range(Key); for (auto i2 = i1.first; i2 != i1.second; ++i2) { if (i2->second > Key) { // <-- Here add your sorting criteria mmap.emplace_hint(i2,Key,Value) return } } mmap.emplace(Key

plotting multiple maps using rworldmap library

问题 I want to plot multiple maps using rworldmap, where each column is a separate month and the rows are years. I know this can be done in ggmap using facet_grid. How can I do this using rworldmap? For example, the mydata file contains columns for the latitude , longitude , month and year of each point. My code so far: library(rworldmap) newmap <- getMap(resolution = "high") plot(newmap, xlim = c(110, 155), ylim = c(-35, -20), asp = 1) p1 <- read.csv("mydata.csv") points(p1$lon, p1$lat, col =

readOGR (rgdal) fails to fetch polygon names from XML

I am trying to import an KML map of CCG boundaries in England ( Available here, 200Kb ) into R using readOGR function from package rgdal . My end-goal is to create a heat-map by colouring CCGs according to some associated value. I have a list with those values next to CCG names in one data frame. I need to match CCG names in that data frame with CCG names in the imported map object, and assign colours based on the value. However, I cannot see any CCG names imported in the map object, although they are present in the KML file. This is what I am doing: library(sp) library(rgdal) library(maps)

I have been trying to get my geocoder working this morning for the following URL but can't seem to figure out what I am doing wrong: http://www.dlplaw.com/media/map.html When clicking encode, the geocoder is doing it's job and returning the correct Lat / Long coordinates but it gets hung up on setCenter. Uncaught TypeError: Cannot call method 'setCenter' of undefined I tried to follow the Google example here and can't understand why this won't work: http://code.google.com/apis/maps/documentation/javascript/examples/geocoding-simple.html Thanks in advance. map is not in scope.

Do embedded GeoJSON styles work with Mapbox GL?

孤街浪徒 提交于 2019-12-06 11:19:33
Is it possible to utilize the built-in properties attribute of a GeoJSON data source to automatically style a Mapbox GL map without having to pre-specify a style? I have a use case where I dynamically load in GeoJSON LineString data that needs to be a particular color and it already has style data built in: {"properties": {"color": "#ffff33"... Right now, I have a rather inelegant setup where the relevant color is parsed out, translated into a style, and added to the map upon every load: $scope.patternPropToStyle = function(props) { var id = 'pattern' + props.pid; var style = { "id": id, "type

Using the pre-installed Google Maps instead of an own activity by using Intents?

时间秒杀一切 提交于 2019-12-06 10:50:40
I just wanted to know whether it is possible to pass geocoords to the google maps app bis intents or something similar. I wrote an app for displaying route, coordinations and so on by myself, but wouldn't it be more elegant to ask google maps itself for displaying this? I don't know if this is possible, but maybe, one of you can answer this question. IF THIS IS POSSIBLE, is it also possible to ask google maps to calculate the route by my CURRENT POSITION? It would be great if one of you can show me a skeleton/dummy code. I have no idea how the intents would have to look like. Dan Lew The
