geocoding

Given a schema defined for documents containing a GeoJSON location; var BranchSchema = new Schema({ location: { 'type': { type: String, required: true, enum: ['Point', 'LineString', 'Polygon'], default: 'Point' }, coordinates: [Number] }, name: String }); BranchSchema.index({location: '2dsphere'}); And some sample data: [ { "name": "A", "location": { "type": "Point", "coordinates": [153.027117, -27.468515 ] //Brisbane, Australia } }, { "name": "B", "location": { "type": "Point", "coordinates": [153.029884, -27.45643] //Also Brisbane, Australia } } ] The following geoNear query is not behaving

I have to work with strings which may contain Lat/Long data, like this: $query = "-33.805789,151.002060"; $query = "-33.805789, 151.002060"; $query = "OVER HERE: -33.805789,151.002060"; For my purposes, the first 2 strings are correct, but the last one isn't. I am trying to figure out a match pattern which would match a lat and long separated by a comma, or a comma and a space. But if it has anything in the string other than numbers, spaces, dots, minus signs and commas, then it should fail the match. Hope this makes sense, and TIA! ^[+-]?\d+\.\d+, ?[+-]?\d+\.\d+$ The ^ at the start and $ at

All I want to do is find out the person IP address so that I can reverse geocode it to find out their latitude and longitude from which they are viewing my web site from. I can do that using Google ClientLocation API but it's unclear to me if I have to load the huge Google Map framework just to use it. Is it possible to simply use the ClientLocation API without having to load all of Google Maps? If so, how? Yes, you only need to use the ClientLocation object in the google.loader namespace so you need not reference the maps api or anything else. For example. <script src="http://www.google.com

I have 2 related rails models class Location < ActiveRecord::Base has_many :rates geocoded_by .... end class Rate < ActiveRecord::Base belongs_to :location end I am using the geocoder gem - http://www.rubygeocoder.com I want to find all rates with a particular pair attribute that are within a certain distance to the user. In SQL, I would do an inner join on the rates SELECT * FROM rates INNER JOIN locations ON rates.location_id=locations.id; Then, insert a where condition to filter on the pair attribute, and then use the Geocoder's near method on the resulting table (the near method works by

I am using Google's reverse geocoding functionality with the maps api v3 to retrieve postal addresses for latitude longitude (when dragging a marker around a map). This is a UK application only, and part of the system requires a full, or near full, postcode to process correctly. However the reverse geocoder regularly returns just the part of the postcode - for example "GU3", even when the actual address returned appears to be complete - for example including street and house number. Is there anyway, preferably google but otherwise if not, of 'snapping' the address to the nearest full postcode?

Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 5 years ago . Is there a way in rails via some mapping API/gem where I can define map areas/map zones (with polygon bounds) and detect if an address falls within a particular zone/area. This is easily done with geokit . First construct a polygon from LatLng: polygon = Geokit::Polygon.new([ Geokit::LatLng.new(0,0), Geokit::LatLng.new(10,0), Geokit::LatLng.new(10,10), Geokit::LatLng

I have an SQL table column with the Geography type: create table dbo.Events ( Id int identity not null constraint PK_Events_Id primary key clustered (Id), Localization geography not null ); How can I get all events in a radius of 40 km? Is this possible? Thank You, Miguel Assuming you have latitude and longitude of the point from which you want to search: DECLARE @Origin GEOGRAPHY, -- distance defined in meters @Distance INTEGER = 40000; -- center point SET @Origin = GEOGRAPHY::STGeomFromText('POINT(-122.084039 37.42227)', 4326); -- return all rows from events in 40km radius SELECT * FROM dbo
