Description:
|
A polygon that crosses the dateline is not rendered properly. Probably because the used JTS library for creating the geometry calculates the wrong envelope.
The attached example creates a data store that contains two features. One polygon not crossing the dateline [10, 30; 10, 40; 110, 40; 110, 30; 10, 30] and one crossing the dateline [150, 50; 150, 60; -150, 60; -150, 50; 150, 50]. It then creates 8 images:
Image c1: Contains longitude 0 to 150. It shows correctly the complete first feature.
Image c2: Contains longitude 0 to 50. It shows correctly the left part of the first feature.
Image c3: Contains longitude 50 to 150. It shows correctly the right part of the first feature.
Image c4: Contains longitude 50 to 100. It shows correctly the middle part of the first feature.
Image d1: Contains longitude 140 to -140. The image shows nothing but it should show the complete second feature.
Image d2: Contains longitude 140 to 180. The image shows correctly the left part of the second feature. Note: in contrast to GEOT-4542 the polygon is handled correctly here.
Image d3: Contains longitude -180 to -140. The image shows correctly the right part of the second feature. Note: in contrast to GEOT-4542 the polygon is handled correctly here.
Image d4: Contains longitude 160 to 170. The image shows nothing but it should show the middle part of the second feature.
