OCTOBER‚ 2003 © YONG HU 2003 · ii · ABSTRACT Airborne lidar has become a commercially viable remote sensing platform‚ and can provide accurate elevation data about both topographic surfaces and non-terrain objects. Its capability of mapping topography and 3-D models of civil objects is uncommon to other remote sensing technologies. This dissertation presents a collection of algorithms developed for automatically extracting useful information from lidar data exclusively. The algorithms focus on

Denali National Park is located in central Alaska and covers an area of 6 million acres. The park is known for its astonishing mountains‚ the tallest being Mount McKinley‚ which is also the tallest mountain in North America. It peaks in at an elevation of over 20‚000 feet‚ almost 4 miles above sea level. The lowest elevation in the park is located at the Yentna River. This National Park‚ located at the center of the Alaskan Range‚ sees on average a 70°F high and a -9°F low every year. The Park has

Planimetric Map. A planimetric map presents only the horizontal positions for the features represented. It is distinguished from a topographic map by the omission of relief‚ normally represented by contour lines. Sometimes‚ it is called a line map. Topographic Map. A topographic map portrays terrain features in a measurable way‚ as well as the horizontal positions of the features represented. The vertical positions‚ or relief‚ are normally represented by contour lines on military topographic maps

Houston Hughes SPC-205-W05 August 23‚ 2011 How to read a topographic map. General Purpose: To inform Specific Purpose: As a result of my speech my audience will be able to clearly read and identify parts of a topographic map. Central Idea: To read a topographic map correctly one should follow four important steps: study the title of your map; examine your legend; study the contour lines; and view the map in 3D. Introduction: I. Topographic maps are not just any ordinary map. There

The Atacama Desert (Spanish: Desierto de Atacama) is a plateau in South America‚ covering a 1‚000-kilometre (600 mi) strip of land on the Pacific coast‚ west of the Andes mountains. It is‚ according to NASA‚ National Geographic and other sources‚ the driest desert in the world.[1][2][3][4] The Atacama occupies 105‚000 square kilometres (41‚000 sq mi)[5] composed mostly of salt lakes (salares)‚ sand‚ and felsic lava flows towards the Andes The Atacama Desert ecoregion‚ as defined by the World Wide

1. Introduction The word ‘Karst’ comes from the Krs Plateau in Slovenia‚ where karst environments were first studied closely. The Slav people use ‘Krs’ to refere to ‘bare stony ground’. More specifically geomorphology refers to karst as a type of terrain characterised mainly by caves‚ sinkholes and complex drainage networks. The majority of karst formations occur in soluble rocks such as limestone and dolomite (although recent discoveries have revealed karst formations in more resistant rocks such

are in sinkholes.) Body I. Sinkholes can be very dangerous but before we find out where they occur most often we need to have an understanding about why they occur. A) The main reason sinkholes occur is Natural causation. 1) Karst Topography is what the geology is like in most places where Sinkholes occur. a) Karst regions have gypsum or
