maps

问题 I'm writing a Java program which adds all of the words on a website into a HashMap, and then assigns them a key of how many times they appear on the page. For instance, if I ran it on a page with only the words "hello, java, coffee, java", the output would be Java : 2 Coffee : 1 Hello : 1 This also ignores certain words that I don't want included. Here's what I have so far. Map<String, Integer> found = new HashMap<>(); // (word,frequency) Matcher match = Pattern.compile(word_pattern).matcher

问题 Good morning, I am currently working on a project in which I need to compute the pairwise distance between some 4000 points. Since I have the coordinates of all the points, computing the straight-line distance between them was not very difficult... But now I would like to compute the same ~ 8 million distances using not the straight-line path but the shortest path by road, as given by GPS software. Can I access Google/Bing/other map services from C# to compute these distances? Thank you very

问题 I'd like to know (from a high level view) what would be required to take a pdf floor plan of a building and determine where exactly you are on that floor plan using GPS coordinates? In addition to location, the user would be presented with a "turn by turn" directions to another point on the map, navigating down hallways, between cubicles, etc. Use case: an iPhone app that determined a user's location and guided them to a conference room or person's office in the building. I realize that this

问题 I have a georeferenced orthofotomap of cmentary. There is layers with foto, graves and roads between them. I'm trying to create WPF application with map control and display map connected with database that I created. I need to allow user to click some grave and then show a overlay with some personal date and button to navigate to this specific grave using routes that I marked before in other program like QGIS. Is there any way to do is with Bing Maps? Or do you know any way to resolve this

问题 Code: var dest1 = document.getElementById('textbox1').value; var request = { origin:start, destination:dest1, travelMode: google.maps.TravelMode[selectedMode] } directionsService.route(request, function(response, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay1.setDirections(response); } }); I am finding a location using google API and then calculating the distance between the searched place and the particular hotel which is coming from my data base, In image you

问题 i've created a dll for gamemaker. dll's arrays where really slow so after asking around a bit i learnt i could use maps in c++ and make a dll. anyway, ill represent what i need to store in a 3d array: information[id][number][number] the id corresponds to an objects id. the first number field ranges from 0 - 3 and each number represents a different setting. the 2nd number field represents the value for the setting in number field 1. so.. information[101][1][4]; information[101][2][4];

问题 We have a running Graphhopper Server in our company for getting routes. Is there a way to find out how far we are driving in each country? e.g if I'm driving from Munich to Vienna I would like to know how many km we are driving in Germany and how many in Austria. 回答1: This is not yet possible out of the box. You'll have to create a feature request for this or implement this on your own: grab the country boundaries, identify the edges/nodes to mark in the graph and then create additional

问题 I get the same result if I use the URL or javascript APIs. If I pass (as an address) the location "M5" for geocoding, rather than returning the location of the M5 Postal Area (Salford, Manchester) the location returned is the centre of the M5 Motorway. Interestingly in the old google maps (http://maps.google.co.uk) I get the same behaviour but the new google maps (same URL) returns the correct area. Is there another way I can define the location (rather than 'address') that will be more

问题 I'm a noob to Android so bear with me and apologies if my post is moronic. Basically, I'm trying to add a mapview to the XML which is causing a few problems, the error I'm getting is: 06-30 12:29:04.760: ERROR/AndroidRuntime(320): java.lang.NoClassDefFoundError: package.android.mapclass From what I can tell the error is happening on this call: Intent i = new Intent(oldclass.this, mapclass.class); The mapclass itself is: package package.android; import android.app.Activity; import android
