I have geodata from a database in the form of e.g.:
565123.71392795,5930168.553
When looking for the general region of 56°,59° I can tell that this is completely wrong.
The location should be somewhere around 53.5°,10°
Is this even a valid geolocation format?
It is the UTM Format or Universal Transverse Mercator format. As the Location is in Germany it should be:
32U565....,59301...
For further Information see https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system

I'm looking for some help on comparative OpenLayer functions for the following Google maps functions, can someone please let me know what these would be?
I'm currently using
For getting distance, using the distance matrix API:
http://maps.googleapis.com/maps/api/distancematrix
For getting latitude and longitude of the current address:
http://maps.googleapis.com/maps/api/geocode/json?address
Kindly check the attachment which are using for getting latitude, longitude and distance matrix.
Function names:
function getLatLng($add)
function getRoadDistance($from, $to)
--
things are a little bit more complicated in OL than they are with the google-api
Routing: if you have a small road network you can consider creating a Database in PostGIS and use pgrouting to get routing functions, you can find more on it here
Or if you want to use it on a bigger scale there some APIs that do it for you, for example yourNavigator, you'll have to make a get request with your coordinates like this
http://www.yournavigation.org/api/1.0/gosmore.php?format=geojson&flat=startLatitude&flon=startLongitude&tlat=destLatitude&tlon=destinationLongitude
there is also the OSRM for the same purpose.
to get the longitude and latitude based on an address you can use the geocoder for Openlayers 3
that's what I could think of right now, I hope it helps
When searching on Zillow using an address, the URL looks like this:
http://www.zillow.com/homes/{Street}", -"{City}," -"{State}" "{PostalCode}_rb/
However, there seems to be no documentation regarding the use of geographic coordinates in such a url.
How to use latitude and longitude instead of an address?
An answer in Can I search Zillow using latitude and longitude coordinates? - Zillow Questions (the 1st Google result on "Zillow search by coordinates") dated 03.2015 gives an example:
http://www.zillow.com/homes/#/homes/for_sale/fsba,fsbo,new_lt/1_pnd/88.769211,-70.092773,-90,-158.686523_rect/3_zm/0_mmm/
Testing shows that only the http://www.zillow.com/homes and /88.769211,-70.092773,-90,-158.686523_rect parts are required.
It's x0,y0,x1,y1 (the direction between the points can be any). (The coordinates in the example are quite strange and specify an area up to the North Pole. More realistic ones are e.g. 53.67068,-71.323242,13.453737,-127.045898_rect.)
Since the last test, the technique stopped working. Moreover, coordinates appear to have vanished from property details as well!
There is no way provided to bring up a specific object by coordinates - they are instead uniquely identified by an ID (ZPID - Zillow Property ID) - and the way to bring up one as of now is e.g. http://www.zillow.com/homedetails/7044216_zpid/.
A possible reason is there's no way to guarantee that coordinates identify anything or identify something uniquely. I.e. coordinates are conceptually a search term rather than a means of identification.
Finally, do keep in mind that all this is undocumented and is subject to change (you can already see one quite-a-change above). They only support API as the means to access their services programmatically.
I am new to Objective-C, but have written a test app that shows me basic CLLocationManager info such as Heading, Course, Distance, Speed, Latitude and Longitude and the GPS data timeStamp info. What I need is the corresponding UTM coordinates for a given NAD83 and/or WGS84 projection including the UTM Zone letter and numeric designator (e.g. 16-T) wherer I live in northern Indiana. So, if I have :
LAT: 40.410250
LON: -86.127550
I need to convert or obtain through some (hopefully) existing method the UTM Zone, Easting and Northing coordinates of a given LAT/LON coordinate.
Any help is appreciated.
Thanks... Tim
I am trying to use Neighborhood boundaries data(shape files) provide by Zillow.
files available at - http://www.zillow.com/howto/api/neighborhood-boundaries.htm
I am able to read the provided .dbf files but it just have information about state, county, city, name, and region ID.
can some one please guide me to get latitude longitudes or polygon information from this .dbf files or even from shape files.
also how to read the provided shape files?
Use the GetRegionChildren API to get the Lat/Long and other details corresponding to a regionId.
I have the longitude and latitude and the name of the place I want to look for. How do I edit the Google Maps URL so that I obtain all the places (name of the places) near a set of coordinates?
I know I could do this using Google Map API, but just for a link seems a lot of trouble.
You can use the query parameter ll for your lat and long, and you can use the query parameter q for what you want to search.
http://maps.google.com/?ll=39.774769,-74.86084
Or you can
http://maps.google.com/?q=your+query
Yeah, I had the same question for a long time and I found the perfect one. Here are some parameters from it.
https://maps.google.com/?parameter=value
q=
Used to specify the search query in Google maps search.
eg :
https://maps.google.com/?q=newyork or
https://maps.google.com/?q=51.03841,-114.01679
near=
Used to specify the location instead of putting it into q. Also has
the added effect of allowing you to increase the AddressDetails
Accuracy value by being more precise. Mostly only useful if q is a
business or suchlike.
z=
Zoom level. Can be set 19 normally, but in certain cases can go up to 23.
ll=
Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.
sll=
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=
Sets the kind of map shown. Can be set to:
m – normal map
k – satellite
h – hybrid
p – terrain
saddr=
Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.
daddr=
Sets the end point for directions searches, 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.
via=
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=
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.
msa=
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.
reference : http://moz.com/ugc/everything-you-never-wanted-to-know-about-google-maps-parameters
additional info:
http://maps.google.com/maps?q=loc:
put in latitude and longitude after, example:
http://maps.google.com/maps?q=loc:51.03841,-114.01679
this will show pointer on map, but will suppress geocoding of the address, best for a location without an address, or for a location where google maps shows the incorrect address.
As of Jan 2018 (update: still works in May 2022) the latest URL is:
https://google.com/maps/search/*your search string* (address, landmark, city, etc. Spaces are ok)
Examples:
https://google.com/maps/search/empire state building
https://google.com/maps/search/1600 Pennsylvania Ave NW, Washington, DC 20500
You can use the new URL for Google Maps: https://www.google.com/maps/#39.774769,-74.86084,18z
equivalent to http://maps.google.com/?ll=39.774769,-74.86084.
39.774769 is the latitude and -74.86084 is longitude and 18z is 18 zoom level.
Google now has a documentation page dedicated to Maps URLs:
https://developers.google.com/maps/documentation/urls/guide
An API key is not required.
Manipulating one of the examples, I came up with this URL scheme that fits your question:
https://www.google.com/maps/search/<search term>/#<coordinates>,<zoom level>z
A valid example of this would be:
https://www.google.com/maps/search/pizza/#41.089988,-81.542901,12z
This should show you all of the pizza places around Akron, Ohio.
