Hello,

I&nbsp;am&nbsp;trying&nbsp;to&nbsp;get&nbsp;the&nbsp;area&nbsp;of&nbsp;a&nbsp;feature&nbsp;within&nbsp;Bing&nbsp;Maps.

&nbsp;

`//Create Feature based upon Well Known Text you have stored in your database table                        Feature plotPolygon = new Feature(dr["property_wkt"].ToString());                        //Set the field information for each plot polygon based upon what is stored in the database.                        plotPolygon.ColumnValues.Add("id", dr["property_id"].ToString());                        plotPolygon.ColumnValues.Add("name", dr["property_name"].ToString());                        //AreaBaseShape areaShape = (AreaBaseShape)selectedFeatures[0].GetShape();                        //double area = areaShape.GetArea(GeographyUnit.DecimalDegree, AreaUnit.SquareKilometers);                        AreaBaseShape abs = (AreaBaseShape)plotPolygon.GetShape();                                                  //Map1.MapUnit                         double area = abs.GetArea(GeographyUnit.Meter, AreaUnit.Acres);                        plotPolygon.ColumnValues.Add("area", area.ToString());                        //Add the plot to the Plots Layer.                        propertyLayer.EditTools.Add(plotPolygon);`

However&nbsp;the&nbsp;results&nbsp;are&nbsp;way&nbsp;off.&nbsp;&nbsp;My&nbsp;MapUnit&nbsp;is&nbsp;meters&nbsp;because&nbsp;I&nbsp;am&nbsp;using&nbsp;Bing.

Any&nbsp;ideas?

Hi&nbsp;Chad,&nbsp;  
&nbsp;&nbsp;  
&nbsp;What&nbsp;is&nbsp;the&nbsp;unit&nbsp;of&nbsp;the&nbsp;polygon&nbsp;that&nbsp;you&nbsp;want&nbsp;to&nbsp;get&nbsp;the&nbsp;area?&nbsp;The&nbsp;unit&nbsp;must&nbsp;match&nbsp;together&nbsp;to&nbsp;get&nbsp;the&nbsp;correct&nbsp;result.&nbsp;Could&nbsp;you&nbsp;please&nbsp;show&nbsp;me&nbsp;the&nbsp;wkt&nbsp;of&nbsp;the&nbsp;polygon&nbsp;and&nbsp;the&nbsp;result&nbsp;area&nbsp;you&nbsp;get?&nbsp;  
&nbsp;&nbsp;  
&nbsp;Thanks,&nbsp;

Edgar,&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;didn’t&nbsp;realize&nbsp;we&nbsp;had&nbsp;to&nbsp;set&nbsp;the&nbsp;unit&nbsp;of&nbsp;the&nbsp;polygon&nbsp;we&nbsp;create.&nbsp;&nbsp;I&nbsp;thought&nbsp;it&nbsp;was&nbsp;derived/calculated&nbsp;based&nbsp;on&nbsp;the&nbsp;current&nbsp;Map&nbsp;layer.&nbsp;How&nbsp;do&nbsp;you&nbsp;set&nbsp;the&nbsp;unit?&nbsp;  
&nbsp;&nbsp;  
&nbsp;Here&nbsp;is&nbsp;my&nbsp;WKT.&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;POLYGON((-8740988.07592&nbsp;4672318.3084105,-8740541.3970528&nbsp;4672645.5544254,-8740954.6347214&nbsp;4673414.7019934,-8741601.9607801&nbsp;4672872.4768445,-8740988.07592&nbsp;4672318.3084105))&nbsp;  
&nbsp;&nbsp;  
&nbsp;and&nbsp;the&nbsp;result&nbsp;is&nbsp;144&nbsp;acres.

I’m&nbsp;sorry,&nbsp;when&nbsp;you&nbsp;said&nbsp;calculator,&nbsp;I&nbsp;thought&nbsp;you&nbsp;meant&nbsp;there&nbsp;was&nbsp;a&nbsp;thinkgeo&nbsp;class&nbsp;named&nbsp;calculator.&nbsp;  
&nbsp;&nbsp;  
&nbsp;The&nbsp;website&nbsp;([daftlogic.com/projects-google-maps-area-calculator-tool.htm](http://daftlogic.com/projects-google-maps-area-calculator-tool.htm)&nbsp;)&nbsp;gives&nbsp;me&nbsp;~82&nbsp;acres,&nbsp;which&nbsp;is&nbsp;correct.&nbsp;&nbsp;Thinkgeo&nbsp;gives&nbsp;me&nbsp;144&nbsp;acres,&nbsp;which&nbsp;is&nbsp;incorrect.&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;do&nbsp;them&nbsp;both&nbsp;the&nbsp;same&nbsp;way.&nbsp;&nbsp;I&nbsp;draw&nbsp;the&nbsp;polygon&nbsp;on&nbsp;the&nbsp;map.&nbsp;&nbsp;The&nbsp;website&nbsp;does&nbsp;it&nbsp;instaneously,&nbsp;my&nbsp;code&nbsp;in&nbsp;the&nbsp;first&nbsp;post&nbsp;above&nbsp;fires&nbsp;on&nbsp;Save.&nbsp;

Above&nbsp;that&nbsp;is&nbsp;a&nbsp;map.&nbsp;&nbsp;Zoom&nbsp;to&nbsp;the&nbsp;location&nbsp;you&nbsp;want&nbsp;to&nbsp;draw&nbsp;a&nbsp;polygon&nbsp;and&nbsp;draw&nbsp;it,&nbsp;just&nbsp;like&nbsp;in&nbsp;MapSuite.&nbsp;&nbsp;

&nbsp;In&nbsp;addition&nbsp;to&nbsp;that&nbsp;issue,&nbsp;do&nbsp;you&nbsp;know&nbsp;of&nbsp;a&nbsp;way&nbsp;that&nbsp;map&nbsp;suite&nbsp;can&nbsp;have&nbsp;the&nbsp;same&nbsp;kind&nbsp;of&nbsp;functionality&nbsp;that&nbsp;the&nbsp;daftlogic&nbsp;website&nbsp;gives&nbsp;for&nbsp;calculating&nbsp;the&nbsp;area&nbsp;in&nbsp;real-time&nbsp;as&nbsp;you&nbsp;draw.

Chad,

I&nbsp;tested&nbsp;the&nbsp;shape&nbsp;with&nbsp;the&nbsp;web&nbsp;site&nbsp;you&nbsp;provided,&nbsp;and&nbsp;get&nbsp;the&nbsp;result&nbsp;as&nbsp;84,&nbsp;but&nbsp;after&nbsp;I&nbsp;draw&nbsp;it&nbsp;on&nbsp;a&nbsp;bitmap,&nbsp;I&nbsp;calculate&nbsp;its&nbsp;area&nbsp;estimately,&nbsp;and&nbsp;get&nbsp;the&nbsp;area&nbsp;as&nbsp;145,&nbsp;see&nbsp;the&nbsp;attached&nbsp;picture.

 ![](https://community.thinkgeo.com/uploads/default/original/2X/0/029a7c262d91fb7d42d8fb758ff37937742d4b46.PNG)

So&nbsp;I&nbsp;think&nbsp;there&nbsp;must&nbsp;be&nbsp;something&nbsp;wrong&nbsp;with&nbsp;the&nbsp;web&nbsp;site.

For&nbsp;you&nbsp;second&nbsp;question,&nbsp;you&nbsp;can&nbsp;refer&nbsp;to&nbsp;the&nbsp;sample&nbsp;HowDoISamples-\>MapShapes-\>TrackShapeFinishedEvent,&nbsp;there&nbsp;you&nbsp;can&nbsp;draw&nbsp;a&nbsp;shape&nbsp;you&nbsp;want&nbsp;and&nbsp;do&nbsp;anything&nbsp;you&nbsp;want&nbsp;to&nbsp;the&nbsp;feature&nbsp;you&nbsp;drew.

Hope&nbsp;it&nbsp;helps,

Edgar

Chad,  
&nbsp;  
Now&nbsp;I&nbsp;know&nbsp;the&nbsp;root&nbsp;problem,&nbsp;the&nbsp;polygon&nbsp;is&nbsp;projected&nbsp;from&nbsp;decimal&nbsp;degree&nbsp;right?&nbsp;If&nbsp;so,&nbsp;the&nbsp;area&nbsp;should&nbsp;have&nbsp;be&nbsp;changed&nbsp;when&nbsp;projecting,&nbsp;just&nbsp;like&nbsp;the&nbsp;Russia&nbsp;looks&nbsp;much&nbsp;bigger&nbsp;in&nbsp;900913&nbsp;projection&nbsp;than&nbsp;that&nbsp;in&nbsp;4326,&nbsp;so&nbsp;the&nbsp;only&nbsp;way&nbsp;to&nbsp;get&nbsp;the&nbsp;accurate&nbsp;area&nbsp;is&nbsp;converting&nbsp;the&nbsp;polygon&nbsp;back&nbsp;to&nbsp;decimal&nbsp;degree&nbsp;unit,&nbsp;in&nbsp;your&nbsp;case&nbsp;you&nbsp;can&nbsp;do&nbsp;it&nbsp;like&nbsp;this,
