This lesson, part of a series of lessons that use spatial analysis as the inquiry method and GIS as the toolkit, invites you to investigate ranges, means, and extreme values. Objectives: Understand and work with ranges and extreme values within a GIS environment. 20 Questions. Each map layer has a set of data behind it. Sometimes, map data is displayed as points, lines, and polygons, with values stored in tables of data. At other times, map data is stored as grids, composed of individual pixels, or cells, of data, with each pixel stored as a separate value, which may or may not be stored in an attribute table, or database. Each set of data has extreme values that make up the low end and the high end of the range of data.
