Hello all,
I want to generate a vector point from the origin point of a raster.
My raster is an ecw (version 2) format.
I can expose the coordinate values of the origin point by using RasterPropertyExtractor
But, I fail to create the vector point with VertexCreator. I assume this is because the raster still exists and I cannot add a vector point to a raster feature. If I could replace the raster with the vector point, this would work for me.
I thought I might be able to the RasterSubsetter to grab just the top-left pixel and then use RasterCellCoercer to convert that pixel into a point.
This works, but I'm not happy with the result. There is a small shift in the coordinates of the output point.
coordinate units is metres. Coordinate system is GDA-94 Zone 56
The origin point of the original raster
_origin_x : 466000
_origin_y : 6972000
coordinates of output point
x : 466000.14999999997
y : 6971999.850000001
So there is a very small shift in the coordinate that I want to avoid.
Hi @nicholas Use a VertexCreator to make the point from the _origin_x and _origin_y attribute values.
The vertex creator should work as long as you have mode set to "Replace with point"
