2024年12月6日 · This article will cover common imagery tasks that FME users usually carry out, such as modifying bands, resampling to change resolution, and using pyramiding to downsample an image into multiple layers.

2024年6月13日 · Band: A raster dataset can contain a number of different “layers” known as bands. Another way of looking at this is to say each cell can consist of a number of values. Palette: A palette represents each of the pixels in a raster and lists each of the RGB colors associated with each pixel.

FM are a British rock band (referred to as FM UK in North America to avoid confusion with the Canadian progressive rock band FM). They have released fourteen studio albums to date. [1]

2024年11月14日 · Bands can be considered as the layers in a raster dataset. Alternatively, think of each cell as having a number of values (like an FME list attribute). For example, a color raster dataset commonly has three bands: Red, Green, and Blue. There are Red, Green, and Blue layers, or each cell has a value for each band.

A raster is a rectangular matrix of evenly-spaced cells (sometimes called pixels), arranged in columns and rows. A raster – and therefore its cells – has one or more bands (sometimes called channels or layers). A band’s interpretation determines what range and type of values it can hold. Each cell has one numeric value per band.

The RasterBandCombiner receives groups of raster features with one or more bands, and appends all bands to a single output raster feature. The rasters to be merged must align exactly. They must have the same number of columns and rows, and georeferenced rasters must have the same coordinates.
