Converting decimal degrees to bearing and quadrant

DrewDowling

I'm working with the parcel fabric and it seems the database stores line bearings as decimal degrees. Has anybody had to use flex to convert from decimal degrees back to bearings and quadrants?

e.g. 109.4256 to S 70 34' 28" E

If anybody has had to do this already and has an actionscript function / formula or something similar they could give me that would be super.

Thanks for any help

I accomplished this in pretty much the same way. I'm posting the code below in case it helps anybody but I think it does the same as what you posted but in a much less elegant way.

The code takes a result set that is returned from a relationship query. this result set has only one feature set, a collection of line features. Each feature has an attribute called Bearing that has values in decimal degrees. This attributed is then formatted formatted to bearing distance format and then added to an array collection that is bound to a data grid.

            private function onRelatedLines(results:Object, token:Object = null):void
            {
                var intBearing:Number;
                var strPrefix:String;
                var steSuff:String;
                var strDegrees:String;
                var strMinutes:String;
                var strSeconds:String;
                for each( var RelatedResultFS:FeatureSet in results)
                {
                    graphicsLayer.graphicProvider = RelatedResultFS.features;

                    for each( var RelateResultGraphic:Graphic in RelatedResultFS.features)
                    {
                        intBearing = RelateResultGraphic.attributes.Bearing;
                        if (intBearing >= 0 && intBearing <= 360)
                        {
                            if (intBearing >= 0 && intBearing < 90)
                            {
                                strPrefix = "N";
                                steSuff = "E";
                                intBearing = intBearing;
                            }
                            else if (intBearing >= 90 && intBearing < 180)
                            {
                                strPrefix = "S";
                                steSuff = "E";
                                intBearing = 180 - intBearing;
                            }
                            else if (intBearing >= 180 && intBearing < 270)
                            {
                                strPrefix = "S";
                                steSuff = "W";
                                intBearing = intBearing - 180;
                            }
                            else if (intBearing >= 270 && intBearing <= 360)
                            {
                                strPrefix = "N";
                                steSuff = "W";
                                intBearing = 360 - intBearing;
                            }

                            strDegrees = String(Math.floor(intBearing)) + String.fromCharCode(186);
                            strMinutes = String(Math.floor((intBearing - Math.floor(intBearing))* 60)) + "'";
                            strSeconds = String(Math.floor((((intBearing - Math.floor(intBearing))* 60) - Math.floor((intBearing - Math.floor(intBearing))*60))*60*100)/100) + "''";
                            RelateResultGraphic.attributes.Bearing = strPrefix + strDegrees + " " + strMinutes + " " + strSeconds + " " + steSuff;

                           
                            arrcParcelLinework.addItem(RelateResultGraphic.attributes)
                        }
                    }
                }
            }
