I&nbsp;am&nbsp;facing&nbsp;problem&nbsp;in&nbsp;loading&nbsp;my&nbsp;shapefiel.&nbsp;when&nbsp;the&nbsp;application&nbsp;runs,&nbsp;shape&nbsp;file&nbsp;doesnot&nbsp;display.&nbsp;i&nbsp;have&nbsp;checked&nbsp;its&nbsp;map&nbsp;units&nbsp;and&nbsp;put&nbsp;correct&nbsp;map&nbsp;units&nbsp;but&nbsp;still&nbsp;no&nbsp;solution.

i&nbsp;have&nbsp;the&nbsp;same&nbsp;sample&nbsp;code&nbsp;

&nbsp;

private&nbsp;void&nbsp;Form1\_Load(object&nbsp;sender,&nbsp;EventArgs&nbsp;e)  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;winformsMap1.MapUnit&nbsp;=&nbsp;GeographyUnit.Meter;  
  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//winformsMap1.BackgroundOverlay.BackgroundBrush&nbsp;=&nbsp;new&nbsp;GeoSolidBrush(GeoColor.GeographicColors.ShallowOcean);  
  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//WorldMapKitWmsDesktopOverlay&nbsp;worldMapKitDesktopOverlay&nbsp;=&nbsp;new&nbsp;WorldMapKitWmsDesktopOverlay();  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//winformsMap1.Overlays.Add(worldMapKitDesktopOverlay);  
  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ShapeFileFeatureLayer&nbsp;worldLayer&nbsp;=&nbsp;new&nbsp;ShapeFileFeatureLayer(@"E:\Practices\First\_attempt\First\_attempt\bin\Debug\Shapefile\H\_12\_Roads.shp");  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel&nbsp;=&nbsp;ApplyUntilZoomLevel.Level20;  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;worldLayer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle&nbsp;=&nbsp;AreaStyles.CreateSimpleAreaStyle(GeoColor.SimpleColors.Transparent,&nbsp;GeoColor.FromArgb(100,&nbsp;GeoColor.SimpleColors.Green));  
  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;LayerOverlay&nbsp;staticOverlay&nbsp;=&nbsp;new&nbsp;LayerOverlay();  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;staticOverlay.Layers.Add("WorldLayer",&nbsp;worldLayer);  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;winformsMap1.Overlays.Add(staticOverlay);  
  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//winformsMap1.CurrentExtent&nbsp;=&nbsp;new&nbsp;RectangleShape(-139.2,&nbsp;92.4,&nbsp;120.9,&nbsp;-93.2);  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;winformsMap1.Refresh();&nbsp;&nbsp;&nbsp;

Sarah,&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;Might&nbsp;I&nbsp;suggest&nbsp;you&nbsp;project&nbsp;your&nbsp;shapefile&nbsp;to&nbsp;spherical&nbsp;Mercator&nbsp;or&nbsp;a&nbsp;meters&nbsp;based&nbsp;projection.&nbsp;&nbsp;The&nbsp;routing&nbsp;engine&nbsp;though&nbsp;it&nbsp;can&nbsp;work&nbsp;with&nbsp;decimal&nbsp;degrees&nbsp;is&nbsp;fastest&nbsp;and&nbsp;gives&nbsp;more&nbsp;reliable&nbsp;results&nbsp;when&nbsp;you&nbsp;use&nbsp;a&nbsp;feet&nbsp;or&nbsp;meters&nbsp;projection.&nbsp;&nbsp;The&nbsp;reason&nbsp;is&nbsp;that&nbsp;in&nbsp;meters&nbsp;things&nbsp;are&nbsp;on&nbsp;a&nbsp;grid&nbsp;and&nbsp;the&nbsp;distance&nbsp;in&nbsp;one&nbsp;step&nbsp;of&nbsp;x&nbsp;or&nbsp;Y&nbsp;is&nbsp;know.&nbsp;&nbsp;In&nbsp;decimal&nbsp;degrees&nbsp;one&nbsp;step&nbsp;being&nbsp;one&nbsp;decimal&nbsp;degree&nbsp;has&nbsp;different&nbsp;distances&nbsp;depending&nbsp;on&nbsp;where&nbsp;you&nbsp;are&nbsp;on&nbsp;the&nbsp;earth.&nbsp;&nbsp;One&nbsp;decimal&nbsp;degree&nbsp;is&nbsp;different&nbsp;at&nbsp;the&nbsp;equator&nbsp;then&nbsp;near&nbsp;the&nbsp;poles.&nbsp;Converting&nbsp;the&nbsp;data&nbsp;may&nbsp;solve&nbsp;the&nbsp;error&nbsp;you&nbsp;are&nbsp;running&nbsp;into&nbsp;and&nbsp;also&nbsp;allow&nbsp;for&nbsp;a&nbsp;faster&nbsp;and&nbsp;more&nbsp;accurate&nbsp;result.&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;On&nbsp;side&nbsp;benefit&nbsp;and&nbsp;something&nbsp;I&nbsp;suggest&nbsp;is&nbsp;to&nbsp;also&nbsp;use&nbsp;meters&nbsp;and&nbsp;then&nbsp;hook&nbsp;to&nbsp;the&nbsp;event&nbsp;that&nbsp;gets&nbsp;called&nbsp;when&nbsp;you&nbsp;create&nbsp;the&nbsp;rtg&nbsp;so&nbsp;you&nbsp;can&nbsp;adjust&nbsp;the&nbsp;weight.&nbsp;&nbsp;By&nbsp;adjusting&nbsp;the&nbsp;weight&nbsp;you&nbsp;can&nbsp;factor&nbsp;in&nbsp;the&nbsp;speed&nbsp;difference&nbsp;between&nbsp;various&nbsp;classifications&nbsp;of&nbsp;roads.&nbsp;&nbsp;My&nbsp;suggestion&nbsp;is&nbsp;to&nbsp;do&nbsp;the&nbsp;Distance&nbsp;/&nbsp;Speed&nbsp;as&nbsp;the&nbsp;weight.&nbsp;&nbsp;You&nbsp;can&nbsp;look&nbsp;at&nbsp;your&nbsp;shapefile&nbsp;data&nbsp;and&nbsp;see&nbsp;if&nbsp;it&nbsp;has&nbsp;a&nbsp;road&nbsp;classification,&nbsp;if&nbsp;so&nbsp;estimate&nbsp;the&nbsp;speed.&nbsp;&nbsp;In&nbsp;this&nbsp;was&nbsp;if&nbsp;you&nbsp;have&nbsp;a&nbsp;5000&nbsp;meter&nbsp;road&nbsp;with&nbsp;a&nbsp;speed&nbsp;of&nbsp;75kph&nbsp;then&nbsp;the&nbsp;weight&nbsp;would&nbsp;be&nbsp;66.66,&nbsp;this&nbsp;shortens&nbsp;the&nbsp;road&nbsp;as&nbsp;opposed&nbsp;to&nbsp;a&nbsp;speed&nbsp;of&nbsp;45kph&nbsp;which&nbsp;would&nbsp;yield&nbsp;111.11&nbsp;meaning&nbsp;this&nbsp;road&nbsp;seems&nbsp;longer&nbsp;to&nbsp;the&nbsp;algorithm.&nbsp;&nbsp;To&nbsp;do&nbsp;this&nbsp;with&nbsp;decimal&nbsp;degrees&nbsp;is&nbsp;tricky&nbsp;and&nbsp;I&nbsp;don’t&nbsp;suggest&nbsp;it.&nbsp;&nbsp;If&nbsp;you&nbsp;do&nbsp;it&nbsp;this&nbsp;way&nbsp;then&nbsp;you&nbsp;results&nbsp;will&nbsp;be&nbsp;more&nbsp;accurate&nbsp;as&nbsp;it&nbsp;will&nbsp;factor&nbsp;in&nbsp;the&nbsp;faster&nbsp;possible&nbsp;travel&nbsp;speed&nbsp;of&nbsp;highways.&nbsp;

Thanks&nbsp;david,

&nbsp;

My&nbsp;shape&nbsp;file&nbsp;projection&nbsp;is&nbsp;in&nbsp;meters.&nbsp;I&nbsp;got&nbsp;error&nbsp;of&nbsp;this&nbsp;in&nbsp;creating&nbsp;.rtg&nbsp;in&nbsp;mapsuite&nbsp;explorer.&nbsp;

&nbsp;

so&nbsp;how&nbsp;can&nbsp;i&nbsp;solve&nbsp;this&nbsp;problem?&nbsp;i&nbsp;follow&nbsp;the&nbsp;sample&nbsp;example&nbsp;given&nbsp;on&nbsp;mapsuite&nbsp;website.&nbsp;
