//=> 'https://www.google.com/maps?saddr=my%20house&daddr=your%20house'

See it for yourself


var query = {
  saddr: 'home', //starting address
  daddr: ['dest1', 'dest2', 'dest3'], //destination addresses (can be one address)
  dirflg: 'r' //public transit
}

gmap(query);

API

gmap(query)

Returns a string for the Google Maps url associated to your query.

query

Type: object

Query parameters fully documented below. See Query Parameters


gmap.directions(from, to, [query])

This is a convenience wrapper around gmap(query). Returns a string for the Google Maps url associated to your query.

from

Type: string

Starting location. Can be address, cross-streets, lat/long, etc.

to

Type: string or array

Ending location(s). Can be address, cross-streets, lat/long, etc.

query

Type: object
optional

Query parameters fully documented below. See Query Parameters


Query Parameters

Google Maps has a cryptic query system - following this guide to query params, you can craft any url you'd ever need to open in Google Maps:


saddr

string

Sets the starting point. You can also add text into this in brackets to bold it in the directions sidebar.

daddr

string or array

Sets the end point(s), and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

q

string

Specify the search query. eg :

http://maps.google.com?q=newyork or http://maps.google.com?q=51.03841,-114.01679

near

string

Specify the location alternative to q=. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if query is a business.

z

string

Zoom level. Can be set 19 normally, but in certain cases can go up to 23. More information on the super-high zoom level images can be found here.

spn

string

Sets the span width and height that the geocoder will compute. Basically, it limits the number of degrees long/lat that will be shown.

sspn

string

Sets the boundaries for the search span.

mrt

string

Specifies the type of search (left blank by default, which searches everything). Can be set to:

all – all results loc – locations based. Requires q to be filled. yp – the business search. Also requires q to be set, and works better with loc as well. kmlkmz – searches the community maps. Requires a location set either in q, loc or near. websearch – searches webpages that Google has given a geographical position. realestate – gives real estate based results. Obviously.

ll

string

Latitude and longitude of the map centre point. Must be in that order. Requires stringified decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll

string

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t

string

Sets the kind of map shown. Can be set to:

m – normal map k – satellite h – hybrid p – terrain

layer

string

Turns overlays on and off. Can be set to t for traffic or c for street view, or tc for both at the same time.

view

string

Controls the view type. Set to text for text, or map for map.

mrad

string

Allows you to add additional destination addresses. Just as a quick aside, you can use saddr=, daddr= and mrad= instead of "+to:" if you want.

dirflg

string

This controls the route that will be planned. Can be set to h for no motorways, r for public transport only or w for walking directions.

via

string

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg

string

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

cbll

string

The latitude and longitude values for Street View.

cbp

string

Alters the Street View window. Controls (in order) window size, bearing, tilt, zoom and pitch.

start

string

Skips the first match for search

num

string

Controls how many matches are displayed. Will accept values up to 10.

om

string

Set to 1 to open the overview map, or anything else to close it.

ie

string

Sets the input character encoding, e.g., ie=UTF8.

oe

string

Sets the output character encoding, e.g., ie=UTF8.

output

string

Sets the output format. Can be set to:

html - standard js – gives you object literals and function calls kml – an XML file like the one from the start nl – XML formatted NetworkLink wrapper, which links to a URL for information to be used with Google Earth and Google Maps embed – for embedding maps into other sites (also note that this requires the s= param which is obfuscated) dragdir – outputs a JSON object containing the reverse geocode and an encoded polyline for a given route

f

string

Controls the form style. Can be set to d for the directions form, l for the local version, or q for the normal one.

latlng

string

Not sure. Inputs as 3 figures in CVS format, but only uses the last one. Seems to have something to do with business locations. Must be used with valid data for other operators. Also, must have q=.

cid

string

Same as latlng, but allows you to specify map size.

geocode

string

Geocoding service for embedded maps.

Iwloc

string

Does funky things with the info window. Can be set to:

A-J – opens the info window over a business marker near – puts it over the green arrow (when shown) addr – places it over a set address (the default value) start, end and pausex – for use in driving directions, where x is the number of the point in question

iwd

string

Sets the info window to expanded view when set to 1.

iwstate1

string

Puts the infowindow into various edit modes. Can be set to:

sscorrectthiscard – standard edit mode sscorrectthiscard:ssmovemarkercard – for marker position edits sscorrectthiscard:ssedithistorycard – allows you to view a marker’s history

pw

string

Sets print mode.

msa

string

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

string

Specifies My Maps identifiers. Use it with ms and msa=0 to show particular My Maps.

vp
