It is often said that a picture is worth a 1000 words, but in GIS, imagery is far more than just pictures. It is any cell-based (often called raster) data that is spatially aligned. While it might be the color and intensity values of reflected light captured in an aerial photograph; it could also be the average height over 10 square meter blocks in a specific region, or average rainfall, or even a highly detailed Lidar rendering of the ocean floor. In this introductory level session, we will explore imagery as a source of information that supports decision making and helps save time, money, and resources.
