I want to extract pixel value from raster to point file. That's mean each record in point file, it gets a value in raster.
In FME, Can I do it? And if it is possible, how can i do?
Thanks

Hi,
you can use the PointOnRasterValueExtractor for this. Be sure to check the help about the different interpolation type setttings first.

Yes. Thank you. In case, I have multiple raster and only a point file.
I want extract all value in raster to point file ( each raster file has a field in point file).
How can i do?
Thanks

If the rasters do not overlap and it is just one type of attribute you want to map/extract,
You can a dynamice reader on rasters and enter it in the rasterport of the PointCloudOnRasterComponentSetter. (i have never tried that though)
Else Tiler (or a tiling procedure) to do that.
You can extract boundingboxes from rasters, spatialrelate the boundingboxes to point cloud and then send the pointclouds to a tiler using bounds for tiles.
This will also make sure you have linked rastername (fme_feature_type).
Attach a featureReader to Tiler dynamically reed the rasters based on this link (fme_feature_type).
Send output from tiler to PointCloudOnRasterComponentSetter"
Also send output raster from featurereade to PointCloudOnRasterComponentSetter
I hope this is understandable...
