Hi Menion,

I think that problem might still be present. I noticed on a couple of occasions that the points appeared in the wrong position. I loaded the markers while viewing a zoomed in map of my location (200km from where the markers were supposed to appear). The markers showed up in my view (200km error) when I zoom in or out they then jump to their correct position.

Hope that makes sense.

Fantastic,

I guess this will be available in the next update ?

Thanks...

Hi Menion,

Thanks your api is working beautifully. I have one little problem though.  When I import my points, it is as if they arrive in locus at the wrong zoom level.  And initially they are in the wrong position. When I zoom in or out they then jump to the correct location. I was hoping you might have a suggestion for me.

Many thanks once again.

Thanks Menion

Thats a great help. Took a little while to figure out that the time is Milliseconds (Like you said !) and not unixtime like I was doing.
Very happy now. Thanks for the API. Love this software  

Hi,

I'm new to Java so struggling a lot here. I am successfully sending points to Locus from a remote JSON source. Its great. I was hoping to be able to send a little additional data like Speed and Heading and time received. The Geocaching class? has a little too much specialised info/buttons.

This is what I have.   Would anybody be able to suggest a (simple!) way to attach this additional info.

Thanks.

P.S. I don't suppose there is anything built into the API for auto refreshing this content ?  

Code Select Expand

          PointsData pd = new PointsData("callSendMorePoints");

   // Getting Array of remote markers from server
   contacts = json.getJSONArray(TAG_CONTACTS);

   // looping through All Contacts
   for(int i = 0; i < contacts.length(); i++){
       JSONObject c = contacts.getJSONObject(i);

       // Storing each json item in variable
       String label = c.getString(TAG_LABEL);
       String lat = c.getString(TAG_LAT);
       String lon = c.getString(TAG_LON);
       String speed = c.getString(TAG_SPEED);
       String heading = c.getString(TAG_HEADING);
       String received = c.getString(TAG_RECEIVED);
       
      Location loc = new Location(TAG);

       ///convert from string to double
       double aDouble = Double.parseDouble(lat);
loc.setLatitude(aDouble);

///convert from string to double
double bDouble = Double.parseDouble(lon);
loc.setLongitude(bDouble);

/// Anyway to attach my speed and heading with this ?
                       Point mydata = new Point(label, loc);


pd.addPoint(mydata);
        }
       DisplayData.sendData(activity, pd, false);
       }
          catch (JSONException e) {
          e.printStackTrace();
           } catch (RequiredVersionMissingException e) {
// TODO Auto-generated catch block
    e.printStackTrace();
            }
  }

Hi,

You may be interested/already aware of this one (differential GPS from EGNOS) . Perhaps your geocaching/archaeologists/surveyors etc  users might find it useful. SDK link below.

Great. I look forward to it.

Many thanks.

Would love a button to load kml,json or xml as POI's from a URL (set previously in settings). I would like to be able to show the location of a number of tracking devices but could also be used to show Marine AIS etc.

If locus had a text field where you could input your url . i.e. www.yourdomain/locusfeed.php  which would output kml,json or xml in a format decided by you. Then just display those points on the map. when you press the 'fetch' button a second time the points are erased and the new points downloaded - not to be stored just temporary points.

Does that make any sense at all ?

Cheers.

Cool...

Hi Menion,

The Irish grid is working great. there is just one little thing to amend. The positions should always remain in 10 digit. i.e. M 01111 21111 at the moment Locus will drop the first 0 from an easting or northing so the position above would appear as  M 1111 21111. It would be important that the preceding 0 is preserved. I guess if the position is <10000 you could just stick a zero at the front ?

Many thanks,

Genius! Thanks Menion. Appears to work perfectly. Will test loads more during the week. Many thanks. I'm looking forward to working with your software.

Fantastic. I look forward to testing it if you manage to do it. Locus is great. Keep up the good work.

Hi Menion,

Thanks for the reply. I think they are quite similar. The Irish system just uses 1 letter as a prefix see http://goo.gl/n2eUf

There's some javascript code here showing/discussing some of the differences (Half way down the page 'Modifications for Ireland') but I think you are right its mainly the 'Modified Airy' http://goo.gl/O7tPc

Official http://osi.ie transformation booklet http://goo.gl/l2dqw

For the maps. I had some geotiffs (irish grid) I converted them with mapc2mapc (supports irish grid) to moile atlas sqlite. seems to work perfectly.

Hope that is some help, Thanks for your time and effort.

Hi idk,

All topographic maps printed in Ireland (and the UK) use a national grid system (EPSG:29902, there is a newer system ITM but this is generally not in use yet) based on a different projection than wgs84. So basically for a Locus user to be able to refer to the real world - i.e. Look at a position on a paper map, or communicate your position to somebody who is using a paper map you need to use the local system (Ireland is broken into 25 squares, each square has a letter then an easting and northing). There is no useable wgs84 lat/lng degrees/min/sec on a paper map.

All handheld GPS units would have this facility. For Locus or any app to be useable in the real world it really needs to support local grid.

I'm keeping my fingers crossed. Locus is great. I'd love to be able to use it.

Cheers.

Hi Menion,

Please consider this. I'd be willing to wait and I personally will buy 25 full versions. I know there would be hundreds of other Irish people interested. All of our maps use the Irish Grid system. So for any app here to be useful in the real world it has to include the Irish Grid. AlpineQuest does at the moment but with respect to AlpineQuest it's not a patch on what you are achieving here particularly with the POIs. Please.....
