I have a list of Lat and Longs that I would like to display as points/markers on a map. How do I do this. I have been able to do one address using geocodingParams option, but can't see how to do it with multiples. I will have a list of addresses that I would like to geocode and display or I can convert addresses to lat/long and then display. I'm very new to this as you can tell!
Thanks for any help you may be able to give this newbie.
Check out the documentation. There's an example for putting multiple markers on the map: https://developer.here.com/api-explorer/maps-js/v3.0/markers/markers-on-the-map

I want to display several markers (later i want different circle) in Google map.
I want to generate just one link without API key if possible ?
My url example:
https://www.google.com/maps?q=[FORT DE FRANCE,97200]+[DUCOS,97224]+[COUSAIX,87270]+[REMIRE MONTJOLY,97354]+[LE LAMENTIN,97232]
but several points are not displayed !
Please how to do with this just with params ?
Tanks a lot !
I don't think this is possible for multiple points on the URL. It seems what you need is Google maps place marks. If your data is static then you can manually create the points on a google map and embed that link instead.
I have a two lists of locations....(via postcodes or long and lats), and would like to put two lists onto the same googlemap... but representas different colours..
It is a follow up to the original question
postcode distances using google
I.e. Is there a away to put up all the student locations and the school locations on a single google map represented as different colours?
maybe using googleVis?
Sounds like a "categories" map. Here is an example of a categories map from Mike Williams' Google Maps API v2 tutorial ported to the Google Maps API v3.
If you have a significant amount of data it would be impractical to show them all at one time. It would be better to show only one data type eg schools and if you click on an individual marker show the nearest students within a specific radius of that school.
The answer for your last question shows you how to find the coordinates required to display on map
I've searched google every way from Sunday that I could think of but I cannot seem to find an answer to my question.
Right now I have a map that is using a FusionTableLayer to display the location of geocoded addresses. Does anyone know if it's possible to get the LatLng coordinates of the geocoded address without having to do a secondary geocoder call to geocode the address? Or maybe get an array of all of the markers currently displayed?
like myFusionTableLayer.getMarkers() or myFusionTableLayer.getMarkerLocation(index) or something would be helpful.
It is not possible to retrieve the locations from geocoded addresses in FusionTables. It used to be possible, but that capability was removed, I believe for legal reasons.
If you geocode the addresses outside of FusionTables and store the coordinates in the table, they will be available.
Ok, let me preface this question with the fact that I have created a lot of google maps, but they have been strictly markers and polylines denoting routes and a couple with some handler interaction.
Now I am looking to show basically a map of the world, mostly North America and I want to split this continent into my predefined regions with some lats/lngs that I have. Using these regions I want to draw something like a polygon with a light opacity and different color per region.
I then want to use marker clustering but I want the clusters to be specific to these regions. I have looked around but I haven't found an example like this. I have seen pages that say you can do this but not how you would go about doing this. Again, I am definitely a noob when it comes to drawing polygons and using the marker cluster. I know this question is fairly vague but just looking for an example/idea to start off of, and more so I don't want to write a bunch of code against this specific api and then find out that it is not possible.
Any ideas or suggestions are greatly appreciated....Thanks.
It can be done, but will require a rewrite of the MarkerClusterer (probably will simplify it).
You will need to determine how you are going to represent and load the cluster boundary polygons (KML, GeoJSON, native Google Maps API v3 polygons) and probably use the google.maps.geometry.poly.containsLocation(point:LatLng, polygon:Polygon) instead of LatLngBounds.contains to determine which cluster "owns" a marker.
I have a scenario where I have to highlight borders and shade a state or city after geocoding it (when I got the lang and lat).
How can I do this, do I need to have a complete information of a city to surround it with polylines? Or is there a way that map API can do this for me.
True. Google does not provide this feature. So what we can do... we can have the lat/long of the borders of the state. And we have to draw polygons ourselves.
I used this JS object. And changed it to Google map object (google.maps.LatLng).
For example:
var statesobj = {"AK": [new google.maps.LatLng(70.0187, -141.0205),
new google.maps.LatLng(70.1292, -141.7291),
new google.maps.LatLng(70.4515, -144.8163)]}
So, it's easy now. Loop on these lat/longs. And you can draw the polygons on every state of US.
So this is the solution I came up. If you guys know some better idea to do it. Please share.
You can also try Google Geo Charts:
http://code.google.com/apis/chart/interactive/docs/gallery/geochart.html
Google Maps API doesn't allow you to retrieve city borders. There are a couple other places from which you can get the coordinates, though:
Flickr API
There is a Flickr API based on photos that people tag, but it's only as accurate as the people who tag photos: so it's good enough for bootstrapping but probably not for production: http://karya-blog.blogspot.com/2012/12/fetching-city-polygons-with-flickr-api.html
Natural Earth Data
An accurate alternative is www.naturalearthdata.com. To get that data from there you just need to make two requests: one with the city name and one with their ID to get the parameters:
unlock.edina.ac.uk/ws/search?name=berlin&gazetteer=naturalearth&format=json
and then
unlock.edina.ac.uk/ws/footprintLookup?format=json&identifier=14126951
and you're set :)
Mapzen
If it's possible for you to pre-fetch the data, go for Mapzen, they have a full and pretty accurate database: https://mapzen.com/data/borders/
I'm afraid google maps API doesn't provide any means to access region (country, state, city, ...) shapes.
If you want to highlight regions you have to create custom overlays based on data acquired elsewhere.
Now the basic map example includes a "mashup" of data. When identifying data is fed to the web service, the resulting output can pinpoint locations on the map.
It shows how a geographic Map Marker is placed on the map to identify a specific location. Map Markers can use the default icon (shown) or a custom image, gauge, or even a chart. Optionally, the map can be configured to display a Map Marker Info window, containing additional location-specific data, when the marker is clicked.
It includes data-driven, colored regions (in this case, representing postal codes) overlaid a map of eg Washington, DC. Logi Info can work with GIS boundary data to produce region overlays for states, counties, cities, school districts, and other areas. Like the Map Marker, regions can be clicked to display a pop-up information window with detail data.
