How to calculate the altitude above from mean sea level

生来就可爱ヽ(ⅴ<●) 提交于 2019-11-30 00:46:24
I tried to find how to get the altitude above the mean sea level. At this time, it returns altitude from the ellipsoid. So, anyone knows the formula or calculation to change the altitude value from ellipsoid to the altitude value from mean sea level. Thank you for all help As you mentioned, GPS returns the altitude as an offset from the WGS84 reference ellipsoid, but most people want to see mean sea level (MSL), and the two frequently don't agree. The way this is most frequently done is by looking up the delta in a table and using that to compute MSL based on the height from GPS and the delta

Geolocation provider for Firefox that allows manual input

Are there any easy ways to override the default behaviors of the geolocation api and just hard code your current location? I think this would be useful for testing and for privacy reasons (providing fake location data) I thought there was an add on for this but I can't seem to find one. Only option right now seems to be changing the about:config geo.wifi.url to some alternative webservice, which I consider overly complicated. Any ideas? Thanks Ideal Scenario Somebody implements an add-on where a google map appears and I can pick a new default location. Peter Hoffmann The geo.wifi.uri does not

Get your location through python

Is there anyway that I can get the location of my device through python. Currently I am having to use selenium and open up a browser, use a location service website and setting the result of that to variables for lat/long. But is there an easier way to do this? UPDATE: I am using a 3G dongle on my RaspberryPi, so looking for a way to get the specific lat/long of it - I can successfully do this through web service, just wondering if there is a quicker way built into python for these requests? JishnuM Update : This API endpoint is deprecated and will stop working on July 1st, 2018. For more

Location search autocomplete that integrates with bing/google geocoding

Any nice suggestions on auto complete location searches, that integrate with something like Google or Bings location data? I am wanting capture the location of my users on sign up, currently I have a free text input box. I am wanting to have some sort of auto complete that guides the user to inputting more sanitised information, ideally I would like to geo-code the user too. I'm currently using the jQuery autocomplete for the autosearch, but this requires me to provide the location data, which i dont have or want to maintain. If you don't want to maintain your own database of locations (good

Test if html5 geolocation permission already has been granted

问题 Does anyone know if there is a way to test if prior html5 geolocation permission has been granted? I try to make a script that does not request the geolocation unless the permission for the page has already been given. Does not nessicerily have to be html5; other frameworks are also ok. 回答1: According to the Geolocation API Specification there isn't any function for this. Even the option to save it in the browser preferences isn't pushed to your code. If it's realy important and you realy

How to get user's geolocation?

问题 On many sites I saw printed out my current city where I am (eg "Hello to Berlin."). How they do that? What everything is needed for that? I guess the main part is here javascript, but what everything I need for implementing something like this to my own app? (or is there some gem for Rails?) Also, I would like to ask for one thing yet - I am interesting in the list of states (usually in select box), where user select his state (let's say Germany), according to the state value are in another

Storing HTML5 geolocation data

不羁岁月 提交于 2019-11-29 21:58:22
How can I store and process the geolocation (long and lat) of a website user in Rails 3, so that it checks to see if we're already holding those details in a session for that user on every page request (if we're not holding the details, then we should request the user's location from the browser and then store those details in the session)? Based on your requirements I'd say that you don't actually need ajax, since most of the processing will be done using JS (to ask the user for access to their location, parse the response etc), I'd use JS to set a cookie, which Rails will then see). In your

Get exact geo coordinates along an entire route, Google Maps or OpenStreetMap

柔情痞子 提交于 2019-11-29 20:10:33
Suppose I have a route defined from one town to another. From the Google Maps API I can recover a route between the two. However, the route returned from Google is a driving route that includes geo-coordinates only at places where there is another step in a leg (for example, where I have to turn from one highway to another). What I need is geo-locations (lat/long) along the entire route, at specific intervals (for example, every 1/4 mile or 100m). Is there a way to accomplish this via the Google Maps API / web services? Or would the OpenStreetMap database be the way to do it? Kind regards,
