I am currently able to use the Google Maps API to get a route from point A to point B by using the google.maps.DirectionsService. But one thing I cannot seem to get is the actual navigation information (like the one you get when you are on the navigation mode in your cell phone).
Is there any way to get data for things like "turn right in 500 feet on 5th Avenue" ?
Thank you
you may print these instructions by defining the panel-option of the DirectionsRenderer(expects to be a HTML-element where to print the instructions).
Demo: https://developers.google.com/maps/documentation/javascript/examples/directions-panel
To get single instructions you must iterate over the steps of a route and access the instructions-property.

I access a webpage (eg "http://signal.eu.org/osm/#locs=40.853293,14.244461;41.312371,16.288605"), which shows a map control with details of a rail route. On that webpage there exists the map as a control. If I examine the map control using standard Edge functionality, I can see a series of coordinates. I would like to extract these coordinates for use in my VB.Net program. I can handle the desktop part, but the Webpage thing is all new to me. I have tried using a WebClient and downloading as a string, or using a WebBrowser and examining that object, but all I see is the main web page details and not the map control.
Any help would be really appreciated as I have just spent a few hours with google and I feel like I'm not really asking the right question.
If I understand correctly you want the direction of the map. So you want the step by step direction of how to go from "Via Matteo Renato Imbriani, Quartieri Spagnoli, Municipalità 2, Napels, Napoli, Campania, 80136, Italië" to "strada locale, Barletta, Barletta-Andria-Trani, Apulië, 76121, Italië"?
If this is the case, google provides an API exactly for that (Google for "Google direction API").
I've created a map that has the ability to toggle data (markers) and added a search box, but I want to be able to search through my markers like in Google's My Maps, but everything that I've searched for doesn't have this feature and I've clicked just about every link there is on the first two pages and this is the closest I've found, but I'm trying to find (b) and the answer to (b) in this situation is to find any entrees within a certain radius.
This is the search feature that I'm trying to add: Example of Google's My Maps : If I search pancakes, the top results that I get are places that are on the map in which I've mentioned pancakes (instead of any place that serves pancakes).
Everything that I've done so far has been in html/javascript, so if it is possible, please try and stick to those languages.
I'm using Google's Maps API instead of My Maps because I wanted to do some extra toggling with the data that didn't seem possible with My Maps, eg make lower rated restaurants have lower opacity.
Thanks!
Why doesn't google map z (zoom) parameter work inside the url?
I' ve searched over so I got few solutions for sending zoom parameter in google map url but based on the old posts (stackoverflow) which deal with the zoom level within the url it seems that this functionalities do not work anymore.
I've used the following z parameter but it's not working:
http://maps.google.com/?q=38.6531004,-90.243462&z=12
Below is the link where they have mentioned z parameter for zoom level
link
For those who do not want to read,
this works (z range:[1-20]):
https://maps.google.com/?q=38.6531004,-90.243462&ll=38.6531004,-90.243462&z=3
There is no documentation that covers this problem. However, there are few hacks.
The link that you have provided,
URL (stackoverflow):What parameters should I use in a Google Maps URL to go to a lat-lon?
Will not help you with getting the desired google maps zoom level inside a url
The following examples which have been working for quite a while DO NOT WORK anymore (they work but without getting the desired zoom level)
Examples:
http://maps.google.com/?q=38.6531004,-90.243462&z=3
http://maps.google.com/?q=38.6531004,-90.243462&zoom=3
http://maps.google.com/maps?q=Scottish+Rite+Hamilton+ON&loc:43.25911+-79.879494&z=15
Instead, you can get the zoom level easily by trying the following examples:
https://www.google.com/maps/#38.6531004,-90.243462,9z
https://maps.google.com/?ll=40.7060471,-74.0088901&z=3
(Note: after clicking on google maps you will get a gray marker which appears and quickly disappears)
However the above URL's will not give you a static pinpoint for the specified lat&long.
There is a "hack" on how to get a fixed pinpoint (red marker pin) and that is by giving the q attribute (represents the search query) and the II attribute(latitude and longitude of the map centre point) along with the z (zoom attribute)
Example (with the OP coordinates):
https://maps.google.com/?q=38.6531004,-90.243462&ll=38.6531004,-90.243462&z=3
If you want to change the zoom level just change the value of 'z'.
After searching the web I found that only this website:
https://moz.com/blog/new-google-maps-url-parameters
deals with google maps parameters/attributes/arguments, where things actually still work. If anyone want's more functionalities within the url, then this is the site to check.
Zoom intervals explained (https://developers.google.com/maps/documentation/static-maps/intro#Zoomlevels):
The following list shows the approximate level of detail you can
expect to see at each zoom level:
1: World
5: Landmass/continent
10: City
15: Streets
20: Buildings
This works as of 5 Aug 2018
http://www.google.com/maps/place/<lat>,<lng>/#<lat>,<lng>,<zoom>z
For example
http://www.google.com/maps/place/49.46800006494457,17.11514008755796/#49.46800006494457,17.11514008755796,7z
As of 04/2020 ...."because google is always changing and evolving"
In complement to Eugen Sunic comments above, and an alternative update to the Solution.
When Logged in to google and getting map data from the google generator, it is not the same as copying the URL from the browser window (which my may be manipulated to load different zooms trough the various alterations, html, Css and script tricks).
But in the below, keep in mind that Your address info may need to be part of the google array of database, eg you have some address map info linked to your account, images, business name, etc. or not... maybe just typed in for a quick map search with a pin-point... the later I don't know.
Also the below is not some Google API pay per 1k clicks thing, which is more geared to the commercial development end of google tracking heat maps, etc. So if you just need a simple solution and certain zoom and marker to work..then you might try the below.
When logged in too your Google account (maybe not) and showing your location marker on the map screen...
Choose the zoom detail of the map you want to appear in your web page. eg Whole US, State views, City, Street (by clicking the + or - zoom feature).
Then go to the hamburger menu to the left, and look down the list for "Share or Embed Map" and the popup window should load the same zoom level of the map! Do not try to change the zoom in the popup window feature, it wont work to change the link code but will change the pop up windows zoom of the map. In short, the embedded link code is preset and will not change in the popup.
Above this popup window of the map there will be two options at the top (Share and Embed) button/link selections.
Click on the Embed link/button and it should generate the code for the zoom you previously chose.
Lastly, copy the code, paste it into your web page and TEST!
As far as I can tell, There is no altering this code as the others suggested above, changing(z=3, 9z, etc) as the code is entirely different. But it will allow you to get the zoom you need "if the google code generator or procedure does not change".
But the zoom level was altered and good enough for me when I figured the process out. Changing it to other zooms is another can of code.
I'm building an application where user-submitted posts are placed via their location as markers on a Google Map. The users are currently able to view the markers/posts on a map in relation to their current location.
What I'm aiming to do is allow the user to change the location of the map so that users can see the markers/posts in relation to another address, specifically via a form that allows them to enter an address and change the location of the map.
I found a YouTube video illustrating a pretty close approximation of what I'm aiming to do, but it unfortunately provides no code or instructions (http://www.youtube.com/watch?v=4uyIawlsvzU).
Is there a way to efficiently wrap an existing Google Map and the existing markers into a form such as this? I've searched for a solution but can't seem to find the proper way to achieve this. Many thanks for any feedback.
You need to search for LatLng by user specified address and to display it. I see not problems at all :)
Study Google Geocoding API for this (seems best solution for your case) and this example
I have a map of several counties I need to turn into a county select menu (i.e clicking Leicestershire will select Leicestershire.
I am using a php built system that this map will need to return the appropriate value to. I am thinking this will be a get in the url, checked for valid values in the backend.
How would you approach this? A html co-ordinate map? Some sort of Javascript? Flash?
I am aware all those solutions have one drawback or another. Does anyone know a better way of doing this? Or an existing opensource project?
Just an idea, if I read your problem correctly: I would personally use the Google Maps API for this. Plot each county onto your custom Google Map, then when you click each marker an info window could appear with "Select this County". Click the link and pass a value through the URL to your PHP script.
Used a html map system. Dreamweaver made it easy (first time I've used the design screen seriously)
