Hi, I'm having a strange problem that appears to be related to the GeoJSON
driver in GDAL 1.11.0
When reading a polygon geometry in geographical lat/lon coordinates, all my
coordinate values are returned in integer degrees. When using ogrinfo it
dumps the coordinate values with correct decimals, so it must be something
I have done wrong... Here is the relevant code:
OGRDataSource *ds = OGRSFDriverRegistrar::Open(filename_.c_str(), FALSE );
int num_layers = ds->GetLayerCount();
for(int i = 0; i < num_layers; i++)
{
OGRLayer* layer = ds->GetLayer(i);
layer->ResetReading();
OGRFeature* feature;
while((feature = layer->GetNextFeature()) != NULL)
{
OGRGeometry* geometry = feature->GetGeometryRef();
if(geometry == NULL)
continue;
int geom_type = wkbFlatten(geometry->getGeometryType());
if(geom_type == wkbPolygon)
{
OGRPolygon* ogr_poly = (OGRPolygon*)geometry;
OGRLinearRing* ext_ring = ogr_poly->getExteriorRing();
for(int j = 0; j < ext_ring->getNumPoints() - 1; j++)
{
double x = ext_ring->getX(j);
double y = ext_ring->getY(j);
...
Now, the x, and y values here are always truncated to integer values. This
does not happen with for example shp files.
Any ideas what I might have done wrong here?
