kml coordinates value

[iamjohn]

when I use "load KML Overlay", The shape is not correct for the polygon

Is the decimal point accuracy of coordinates value  too low?



Some information of the kml :



<Placemark>

   <Style><LineStyle><color>ff0000ff</color></LineStyle><PolyStyle><fill>0</fill></PolyStyle></Style>

   <ExtendedData><SchemaData schemaUrl="#AB_0206">

      <SimpleData name="AA48">0206</SimpleData>

      <SimpleData name="AA49">00450001</SimpleData>

   </SchemaData></ExtendedData>

      <Polygon><outerBoundaryIs><LinearRing><coordinates>121.522126466999,25.0382063466213 121.522135076823,25.03820360794 121.522142390219,25.038201280078 121.522116851351,25.0381400329444 121.522125360929,25.0381370237732 121.522107221005,25.0380936533499 121.522082778121,25.0381016839535 121.522126466999,25.0382063466213</coordinates></LinearRing></outerBoundaryIs></Polygon>

Whether to plan to improve the display accuracy of KML file coordinates in the future?

Hello;



How do you build the polygon, by hand or using any tool, or a walk (GPS)?

OK, it is a problem with the map projection formulas, when the map is 'google like projected map'



if you use an offline map, all should be OK:

orux

yes~

switch to offline map, all is ok.

Thanks very much~



the polygon is Cadastral line.

Converted from shp to kml.

Will this problem of online  be fixed?
