maps

I'm mapping the following table of multi-drug resistance trends in the US: MDR by region Using the following code: states_map<-map_data('state') m <- ggplot(ncftrendsort, aes(map_id = region)) + geom_map(aes(fill = ncftrendsort$mdr), map = states_map, color = 'black') + expand_limits(x = states_map$long, y = states_map$lat) + theme_classic() + scale_fill_continuous(name = "% MDR", low = 'white', high = 'black') + theme(axis.title.y = element_blank()) + theme(axis.title.x = element_blank()) + theme(axis.line = element_blank()) + theme(axis.ticks = element_blank()) + theme(axis.text.x = element

A problem occured while building application with 'react-native-maps' here is my setting.gradle file include ':react-native-maps' project(':react-native-maps').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-maps/android') dependencies of android/app/build.gradle file dependencies { compile project(':react-native-maps') compile fileTree(dir: "libs", include: ["*.jar"]) compile "com.android.support:appcompat-v7:23.0.1" compile "com.facebook.react:react-native:+" // From node_modules compile 'com.airbnb.android:react-native-maps:0.6.0' } Here is my MainActivity.java

I have a problem with mouseover events in choropleth maps. I would like to highlight the boundary so that the user can see the currently selected feature. That all works fine expect that some of the boundaries are much thinner or do not exist at all presumably because they are rendered below the boundary of an adjacent feature. Here is an example: Some of the boundary is correct, other parts are thinner and a third part does not exists at all. The recent NYT maps from Mike Bostock et al solved this problem. What is the solution? Here is my current mouseover code: .on("mouseover", function(d,i)

Is there a way to insert an address into a link and have it bring up the street view? For instance: <img src="http://maps.google.com/?q=ADDRESSHERE&view=streetview" /> Street View now has a static images API. Here's an example: http://maps.googleapis.com/maps/api/streetview?size=640x480&location=43.0635309,141.3253261&fov=120&heading=235&pitch=10&sensor=false Here's the docs: https://code.google.com/apis/maps/documentation/streetview/ 2011: 2017: Might be best to use Google Maps JavaScript API v3 to do it. See documentation and sample code at http://code.google.com/apis/maps/documentation

I'm trying to create a map application but the examples I find describes a myMap.Children list that my myMap object does not have :-( I've created a map, pretty much straight forward: <maps:Map Visibility="Collapsed" Name="MyMap" Height="670" Width="400" ZoomLevel="10" Pitch="0" CartographicMode="Hybrid" Margin="30,0" /> So how can I in C# add PushPins, and could these have a image from Assets ? See Nokia's Maps tutorial on " Adding Graphics to a Map control " or see MSDN's " How to add UIElements to a Map control in Windows Phone 8 ". It's mostly around adding you own MapLayer with multiple

I have a Mercator projection map as a JPEG and I would like to know how to relate a given x, y coordinate to its latitude and longitude. I've looked at the Gudermannian function but I honestly don't understand how to take that function and apply it. Namely, what input is it expecting? The implementation I found (JavaScript) seems to take a range between -PI and PI, but what's the correlation between my y-value in pixels and that range? Also, I found this function which takes a latitude and returns the tile for Google Maps, which also uses Mercator. It would seem that if I knew how to inverse
