Get Google map - lat/long

[Peter.Greulich]

Is there a way to get the latitude/longitude from an address using G-maps?

If you use lat/long mean the 2500 Google request limit is waived?

Yes there is, there is an action js to do it or an XBasic function check out the wiki: http://wiki.alphasoftware.com/How+to...a+database+V11
The 2500 limit is for geocoding so yes it is waived when you use lat/lon

Re: Get Google map - lat/long

The 2500 limit is for # of addresses for which you can request the lat/long in a day. Once you've got them stored you can use an unlimited # it seems. In my experience you must use lat/long for the map if you're displaying more than a couple of records' data (>10 is a no go, i believe).

Re: Get Google map - lat/long

Hi Peter & Frank,
while believe you 2 are amongs the few who tackle with geo coordinates.
is there a way to run the Geolocation function and have the values be
saved in session.variables directly ?

instead of binding it to a dialog ? then painfully save them to session.variable

Thanks

Re: Get Google map - lat/long

by the way, these are the function listing in java that populate my dialog.
which is working. Can someone share how to add an extra function
to perform the ajax callback right after these codes to save
the coordinates in session.variables ?

appreciate input...

function geoLocateSuccess(pos){
{dialog.object}.geolocation.accuracy = pos.coords.accuracy;
{dialog.object}.geolocation.altitude = pos.coords.altitude;
{dialog.object}.geolocation.altitudeAccuracy = pos.coords.altitudeAccuracy;
{dialog.object}.geolocation.heading = pos.coords.heading;
{dialog.object}.geolocation.latitude = pos.coords.latitude;
{dialog.object}.geolocation.longitude = pos.coords.longitude;
{dialog.object}.geolocation.speed = pos.coords.speed;
{dialog.object}.geolocation.timestamp = pos.timestamp;
try{
populateControls_fireCallback();
}
catch(e){
alert('Callback function error : ' + e.message);
}
}

function geoLocateFailed(error){
switch(error.code){

case 0:
alert('Geolocation error : An unknown error occured.');
break;
case 1:
alert('Geolocation error : Permision to use GeoLocation Service denied by user');
break;
case 2:
alert('Geolocation error : Position not available');
break;
case 3:
alert('Geolocation error : Timeout');
break;
}
}

{dialog.object}.geolocation.clearWatch = function(){
if (typeof {dialog.object}._watchID != 'undefined'){
navigator.geolocation.clearWatch({dialog.object}._watchID);
delete {dialog.object}._watchID;
}
}


function populateControls_fireCallback(){
{dialog.object}.setValue('LATITUDE',{dialog.object}.geolocation.latitude );
{dialog.object}.setValue('LONGITUDE',{dialog.object}.geolocation.longitude );
}

Re: Get Google map - lat/long

From the wiki:

Google has a query limit of 2,500 geolocation requests per day and a rate limit to prevent abuse.
The rate may be what Peter was bumping into.

From Google Maps API doc:

Use of the Google Geocoding API is subject to a query limit of 2,500 geolocation requests per day. (User of Google Maps API for Business may perform up to 100,000 requests per day.) This limit is enforced to prevent abuse and/or repurposing of the Geocoding API, and this limit may be changed in the future without notice. Additionally, we enforce a request rate limit to prevent abuse of the service. If you exceed the 24-hour limit or otherwise abuse the service, the Geocoding API may stop working for you temporarily. If you continue to exceed this limit, your access to the Geocoding API may be blocked.
Note: the Geocoding API may only be used in conjunction with a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.

So what is alpha using for the geolocation if this is prohibited when not using a map?

Sorry I think the geolocation api is not a google thing.

Re: Get Google map - lat/long

What would be the use of geocoded stuff if not displayed on a map?

Re: Get Google map - lat/long

Being able to upload your location to a database. Bob Moore has a video displaying this but I cant get it to work. This one actually has a map but the geolocation code is on the button and is not working.

Re: Get Google map - lat/long

HI,
I asked this question many times on this board,
strange thing, not a single reply.
I begin to wonder if no one else using it ?
or they expect me to go Google college to learn?

i saw the video # 40 and have used it and get it to work very well.

i was just wondering if one can share the idea of
placing the geaolocation trap on a simple .a5w page

typical our famous index.a5w where we place our login
so when a user/anyone open this page.

i want to trap his/her geolocation codes into an sql table.
more like a visitor log ???

again, this to occur before he/she login in.
just stand at the front door, i want to know who ?

Then, once he/she logged in properly.

i want the geocode as

session.latitude
session.longitude

you know we would have his "ulink" by then.

Re: Get Google map - lat/long

OK so it cant be directly in a tabbedui or at least for me. Put it on its own page and voila. But very inaccurate as far as I am concerned within only 600yds from an android cell phone. But at least it works on the phone.

Chad:

What type of Android phone are you using? Samsung phones have a known GPS bug (and there is a fix). I routinely see GPS results <50 ft if outside or near a window.
My Motorola Android phones get similar results and need no patching.

Re: Get Google map - lat/long

I am using a Samsung Note I have now figured out that if I use firefox and not the original internet browser it is accurate to about 15 feet.

Re: Get Google map - lat/long

Chad:

Good to here.

For others I found that without the GPS fix on Samsung the problem was browser independent. The only possible problem for some users is that the GPS fix requires "rooting" the phone.
