How can I use GeoJson to draw Polygon by coordinates in a in WPF xamMap
the GeoJson Format is like this
{ "type": "Feature", "properties": { "POSTNR_TXT": "2400", "POSTBYNAVN": "København NV" }, "geometry": { "type": "Polygon", "coordinates": [ [ [ 12.507469981824794, 55.697642162728606, -999.0 ], [ 12.513470122147424, 55.704428732464073, -999.0 ], [ 12.516776939745267, 55.704245855645013, -999.0 ], [ 12.511408705114711, 55.708960962304033, -999.0 ], [ 12.512190041441698, 55.711319645986919, -999.0 ], [ 12.507081679280693, 55.710984380633825, -999.0 ], [ 12.500766360708445, 55.716490781902046, -999.0 ], [ 12.500985311351469, 55.720444029925297, -999.0 ], [ 12.513211464550546, 55.719649477195055, -999.0 ], [ 12.514651499558028, 55.722689456470626, -999.0 ], [ 12.515294107031444, 55.722867782463666, -999.0 ], [ 12.519599152820591, 55.727566179811724, -999.0 ], [ 12.521429690746064, 55.728193692183275, -999.0 ], [ 12.527186067082091, 55.726885261036692, -999.0 ], [ 12.53516392512655, 55.727108311290323, -999.0 ], [ 12.538297517729665, 55.726441897451792, -999.0 ], [ 12.539753549623979, 55.72373406410744, -999.0 ], [ 12.54589448194818, 55.722725109856434, -999.0 ], [ 12.541971137748702, 55.718870330709052, -999.0 ], [ 12.546457224964172, 55.712452149815277, -999.0 ], [ 12.544526324718129, 55.707857018746353, -999.0 ], [ 12.536143185683914, 55.700583391844624, -999.0 ], [ 12.536372822732455, 55.697864443219281, -999.0 ], [ 12.526200122493627, 55.696983645247528, -999.0 ], [ 12.527793477603566, 55.695617229006025, -999.0 ], [ 12.52099778827445, 55.693472711687498, -999.0 ], [ 12.517520839568377, 55.690854953735794, -999.0 ], [ 12.515978245965664, 55.691009423423061, -999.0 ], [ 12.507469981824794, 55.697642162728606, -999.0 ] ] ] } },
Hello Thomas,
In order to use this type of JSON data in an Infragistics map control, I would recommend that you instead utilize the XamGeographicMap rather than the XamMap, as the XamMap would require you to convert your data into a .shp file prior to creating a layer for the data. The XamGeographicMap also will not take this form of data directly, but you can read the JSON data in and create (X, Y) Points for it and then use it with a GeographicShapeSeries.
I am attaching a sample project that takes the sample data that you have provided here and converts it into a List<Point> to plot it with a GeographicShapeSeries. I hope this helps you.
Please let me know if you have any other questions or concerns on this matter.

How can I remove all the map details like roads etc and where did you get the Rect values ?
Just a couple of questions
