In topological editing, briefly describe the purpose of ranking the feature classes.

Suppose you want to incorporate a newly acquired satellite image into an existing GIS project. Briefly explain why that image must first undergo the process of geometric transformation.

Bilinear interpolation is a resampling method that fills each pixel of the georeferenced image with a value that interpolates among the ________ nearest pixels in the original image.

Which transformation method allows rotation and translation, but not skew or differential scaling?

An affine transformation of a unreferenced satellite image requires a minimum of ________ control points:

Suppose you needed the geographic positions of all the emergency call boxes on the PLNU campus for a GIS project. Briefly describe how you could acquire such data.

Suppose in the process of georeferencing an image, the root mean square error (RMSE) was found to be unacceptably high. What is the first thing you should do to attempt to reduce the RMSE to acceptable levels, before proceeding with the transformation?

The origin of a raster is at the ______corner of the raster:

A raster with a larger cell size has a higher spatial resolution than a raster with a smaller cell size.

How is it possible to compress a raster file without losing ANY information stored in the file? In other words, briefly explain how lossless compression works with an example.
