geonames

问题 Sorry if this is repetitive, but I've looked everywhere and can't seem to find anything that addresses my specific problem in R. I have a column with city names: cities <-data.frame(c("Sydney", "Dusseldorf", "LidCombe", "Portland")) colnames(cities)[1]<-"CityName" Ideally I'd like to attach a column with either the lat/long for each city or the time zone. I have tried using the "ggmap" package in R, but my request exceeds the maximum number of requests they allow per day. I found the

问题 In my application i want to get the weather report I'm using http://www.google.com/ig/api?weather="" for that by providing a city. But for me only lat and longitude is available How can I get the place name by lat and longitudes. 回答1: FYI, what you're doing is called reverse geocoding. Most of the Geonames webservices are available in JSON, including findNearby. Google also has a reverse geocoding webservice What you're asking is not a small thing - a lat/lng database is almost certainly

问题 This question already has answers here : How to get a time zone from a location using latitude and longitude coordinates? (15 answers) Closed 12 months ago . I am trying to get the time zones for latitude and longitude coordinates but am having a few problems The mistakes are probably very basic I have a table in a database with around 600 rows. Each row contains a lat long coordinate for somewhere in the world I want to feed these co-ordinates into a function and then retrieve the time zone.

问题 Consider the following extract from the GeoNames database : @prefix gn: <http://www.geonames.org/ontology#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . <http://sws.geonames.org/690791/> a gn:Feature ; gn:featureClass gn:A ; gn:featureCode gn:A.PCLI ; gn:alternateName "Україна"@uk , "ܐܘܟܪܢܝܐ"@arc , "Ուկրաինա"@hy , "ウクライナ"@ja , "Úkraína"@is; gn:name "Ukraine" ; gn:officialName "Ucraína"@gl , "Ukraine"@fr , "U-crai-na (Ukraine)"@vi , "ཡུ་ཀརེན།"@bo. So, I'm trying to get the name in

问题 I have a list of places which I would enrich with the IDs from geonames. Since geonames by default it's embedded into WikiData I chose to go directly via SPARQL using WikiData endpoint. My workflow: I have imported the excel file into OpenRefine and created a new project In OpenRefine I have created my graph, then I have downloaded it as RDF/XML. Here a snapshot: <rdf:Description rdf:about="http://localhost:3333/0"> <rdfs:label>Aïre</rdfs:label> <crm:P1_is_identified_by>5A1CE163-105F-4BAF

问题 I have read this post and it looks very promising. However, the answer does not go in detail with regards the implementation. Basically, given the latitude and longitude, how can I use the GeoNames Web Service to get the country. I would like the returned result to be stored in a variable so that I can then continue working with it as I wish. Thanks in advance 回答1: Do you have to use javascript for that? Geonames doesn't seem to offer a javascript api for doing your exact query (see here:

问题 i'm trying to use geonames database (downloaded and loaded on a local mysql) to get all associated informations from a location (lowest level is cityname) using Java and JDBC drivers. I have a big performance issue: each query takes something like 4-5 seconds, and i have to split the query in three parts before getting all the results i need. Basically, i have loaded the allCountries database, the admin1codes and the admin2codes. Since admin1 and admin2 unique ids are composed by information

问题 So I'm using the GeoNames API to get country and state/province information which I'm using to populate select dropdowns in a form. This form submits it's information to a SOAP web service and the SOAP Server only understands the country and state/province data in 2 letter form. ie. CA for Canada, US for United States. The GeoNames API provides this information for the different countries but not for their children (states/provinces). Does anyone know how to get the 2 letter abbreviation for

问题 I built an ontology in Protégé 4 to describe archaeological finds and I'd like to use Geonames individuals as places of discovery. How can I add external individuals in Protégé? Do I need to import the Geonames ontology in mine? I tried to: import geonames ontology add new individual with geonames full iri add property sameAs between my place and the new individual of the point 2 but importing the Geonames ontology makes the reasoner to die with this error message: OWLReasonerRuntimeException

问题 I am trying to get linked data from geonames in the following SPARQL, but obviously I'm doing someting wrong. prefix oxprop: <http://ophileon.com/ox/property#> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix owl: <http://www.w3.org/2002/07/owl#> prefix wgs84_pos: <http://www.w3.org/2003/01/geo/wgs84_pos#> select ?poi ?poiname ?geonames ?latitude from <http://www.ophileon.com/ox/poi.rdf> # from <http://sws.geonames.org/ > where { ?poi rdfs:label ?poiname. ?poi owl:sameAs ?geonames.
