Hands-Off Spreadsheets

The wealth of functionality in the Excel software package means it can go beyond use as a static evaluator of predefined cell formulae, to be used actively in manipulating and transforming data. Due to human error it’s impossible to ensure a process like this is always error free, and frequently the sequence of actions is recorded only in the operator’s head. If done regularly by highly paid st...

Forest Fire Detection by Satellites for Fire Control

Infrared sensors on board satellites have been widely used to collect statistics on fires, but not for fire control. Since the polar-orbiting satellites cover the northern Earth latitudes several times a day, their data are particularly suitable for detecting boreal forest fires. Currently, radiometers on board NOAA and ERS-2 satellites are used for operational fire management in Finland. Telef...

Forest-fire detection by means of lidar

Lidar is a promising tool for forest-fire monitoring because, due to its very high sensitivity and spatial resolution, this active detection technique enables efficient location of small smoke plumes that originate from forest fires in the early stages of development during both day and night and over a considerable range. Earlier experiments carried out by the authors testify that small fires ...
