Resampling - Extrapolating pixels values for a new grid from values in an old grid. It is applied after an image is rectified to a projection system or registered to another image (TWS) ...
resamplingThe process of reducing image data set size by representing a group of pixels with a single pixel. Thus, pixel count is lowered, individual pixel size is increased, and overall image geographic extent is retained.
[edit] Resampling Low-pass filtering and resampling affect acutance.
Resampling with nearest neighbor and bilinear method (r.resample, r.bilinear) Inverse distance weighted average (IDW) interpolation (r.surf.idw and r.surf.idw2) Regularized spline with tension (RST) interpolation 2D (r.resamp.rst) ...
Resampling of the radial data into a gridded coordinate system is performed by taking a smaller resolution than the range bin length of 1 km.
Resampling usually changes the statistical and spectral qualities of a grid. For example, both bilinear and bicubic interpolation, being true interpolation methods, rarely exactly reproduce the maximum or minimum values in a grid.
Resampling - A technique in digital image processing that interpolates pixels in the source data to new locations of transformed pixels, usually coinciding with a georeferenced grid. ...
however, resampling will likely be needed in order that pixels coincide in each layer because remote sensing generates images, it is easier to interface with a raster GIS than any other type ...
- establish resampling method or compression for transmission Available image server processes include: stack bands, image algebra, spectral matrix, grayscale, stretching, convolution filters (sharpen), pan-sharpen (fuse low-res with high-res), trend, ...
[mathematics] A resampling method that uses a weighted average of the four nearest cells to determine a new cell value.
Rectification typically involves rotation and scaling of grid cells, and thus requires resampling of values. referential integrity The capability to ensure that changes to one table that affect other tables are transmitted to those other tables.
The ground sample distance of the digital orthophoto is a result of the scanning aperture of the microdensitometer used to capture the digital image and the resampling algorithm.
Non-native resolutions have to be supported by approximate resampling in the LCD controller, using interpolation algorithms (in CRTs, the physical system interpolates between the logical pixels and the physical phosphors).
One can combine in such a way a raster image with several vector layers in one map window by dragging the vector data without the need of resampling the raster image.

Note as you zoom in, you do not see individual cells. This is because the Stretched symbology method also applies a resampling to smooth the appearance of the display. Open the Properties for the layer and click the Symbology tab.

Rectify The process by which an image or grid is converted from image coordinates to real-world coordinates. Rectification typically involves rotation and scaling of grid cells, and thus requires resampling of values.
Precise fit without iterations Rotate a raster image by squaring a horizontal, vertical, or diagonal axis Ability to offload processing to a convenient time with batch resampling Multiple warping methods ...
