Lesson 1: Lidar Sensors | GEOG 497D: LIDAR Technology and Applications Printer-friendly version Introduction In Lesson 1, you will become familiar with the components of an operational lidar and how it works as a mapping system. The history of lidar began about 50 years ago, and it was primarily used as a tool for scientific investigation. At the end of this lesson, you will have a working knowledge of lidar sensor design, integral components of a mapping system, and basic characteristics of lidar data. Lesson Objectives At the successful completion of this lesson you should be able to: Define “lidar” and differentiate it from other remote sensing technologies, such as photogrammetry and radar.Explain the basic principles of physics governing the interaction of laser energy with surface features.Describe the historical development of lidar sensors.Identify key design components of lidar sensors, including single-return, multi-return, waveform, photon-counting, multispectral, and hyperspectral.

GISCI Practice @ Celestial Navigation Yogi Berra said, “In theory, there should be no difference between theory and practice, but in practice, there is” (or maybe he didn’t; and apparently he once said, “I didn’t really say everything I said”). This website cannot teach the actual practice of celestial navigation; however, by reading these pages, you should be able to move on to an on-site or correspondence course with an understanding of what you are doing. If you are new to Celestial Navigation, read at least the Theory and Navigational Astronomy pages first. Ed Falk’s awesome page working out a sample “leg” from the Silicon Sea series of problems. Crystal clear, complete with plotting sheets and everything you need to see a problem worked out in detail!

The parts, which in the impression appear black, were in the original filled up with a melted substance, for the most part brown, but where ship’s sails are represented, white, and for flames, red. This map was discovered in an antique shop and bought by Cardinal Borgia for his museum in Velletri. According to the Swedish scholar A.E. It seeks to give the idea not only of the geography of the different countries, but also of their ethnography, natural conditions and religion, and of the most momentous periods of their history.

Course Overview We chose the title, "Location Intelligence for Business" for this course in lieu of "Business GIS" or "Business Geography" with reason. In business, the application of maps and mapping technology ranges from long present (in commercial real estate, retail, and logistics) to nascent in many industries. What will be expected of you?
Natural Earth Lesson 5: Interpolation - From Simple to Advanced | GEOG 586: Geographic Information Analysis Printer-friendly version Introduction In this lesson, we will examine one of the most important methods in all of spatial analysis. Frequently data are only available at a sample of locations when the underlying phenomenon is, in fact, continuous and, at least in principle, measurable at all locations. The problem, then, is to develop reliable methods for 'filling in the blanks.' The most familiar examples of this problem are meterological, where weather station data are available, but we want to map the likely rainfall, snowfall, air temperature, and atmostpheric pressure conditions across the whole study region. The general name for any method designed to 'fill in the blanks' in this way is interpolation. Learning Objectives By the end of this lesson, you should be able to Questions? Please use the 'Week 5 lesson and project discussion' forum to ask for clarification on any of these concepts and ideas.
Classics - John Snow: The London Cholera Epidemic of 1854 It wasn't until 1854 that Cholera struck England once again, that Snow was able to legitimate his argument that Cholera was spread through contaminated food or water. Snow, in investigating the epidemic, began plotting the location of deaths related to Cholera (see illustration). At the time, London was supplied its water by two water companies. One of these companies pulled its water out of the Thames River upstream of the main city while the second pulled its water from the river downstream from the city. A higher concentration of Cholera was found in the region of town supplied by the water company that drew its water form the downstream location. After the panic-stricken officials followed Snow's advice to remove the handle of the Broad Street Pump that supplied the water to this neighborhood, the epidemic was contained. Snow's classic study offers one of the most convincing arguments of the value of understanding and resolving a social problem through the use of spatial analysis.
