geolocation

问题 I have a coordinate and I need to get the streets name that are between this point. For example, I get the point "Manuela Pedraza 3050" (or geolocation, doesn't matter) and I need to retrieve the values "Zapiola" and "Conesa". Is this possible? 回答1: Concept: create a circle of 8 (as an arbitrary number) of points at 100 meters from your point of interest. get directions from your point of interest to each of those points (you will probably need to use walking directions in that area as the

问题 This question already has an answer here : Closed 7 years ago . Possible Duplicate: Android: how to cancel a request of Location update with intent? I am trying to disable a pending intent(broadcast) which I have previously created in a different activity but I can't get it to work.

问题 I used a network sniffer and examined all the requests going out from Firefox when going to http://html5demos.com/geo. According to my Firefox, the geolocation service according to geo.wifi.uri entry is https://www.google.com/loc/json. However I don't see this url in any of the requests.

问题 When using geolocation API's navigator.geolocation.getCurrentPosition() how to deal with a negative response? It says that the second callback function is called when there is an error. However when user chooses not to reveal his location by cancelling the request that function is never fired. It seems that getCurrentPosition() waits for an answer indefinitely. (at least in Firefox 4) How can I know when user presses cancel (or no etc.) Any ideas? 回答1: See edit below You are correct, the

问题 So ran into this issue today, where I have a website that needs the geolocation of the user. It was working fine when running locally on localhost, but now I get an error saying "Access to geolocation was blocked over insecure connection to http://localhost:4200". WTF Apple?

问题 I can't seem to find much documentation on this. What's the simplest way to create a database/table on postgres supporting a query like this SELECT * FROM table WHERE distance(POINT(0,0), table.location) <= 1000m; Where POINT(0,0) and table.location should be latitude/longitude pair, and 1000m is 1000 meters. And how should I go about indexing that table? Thanks. 回答1: PostgreSQL support indexes on expressions and also partial indexes, you can probably mix them. This is just a random guess, I
