, where users create FlashCards and share them with others. Click on the large flashcard to flip it over. Then click the green, red, or yellow box to move the current card to that box. Below the flashcards are blue buttons for other activities that you can try to study the same information. To flip the current card, click it or press the Spacebar key. To move the current card to one of the three colored boxes, click on the box. You may also press the UP ARROW key to move the card to the ‘Know’ box, the DOWN ARROW key to move the card to the ‘Don’t know’ box, or the RIGHT ARROW key to move the card to the Remaining box. You may also click on the card displayed in any of the three boxes to bring that card back to the center. <,iframe class=’studyStackFlashcardIframe’ src=’https://www.studystack.com/inewflashcard-1525658′ width=’850′ height=’440′ frameborder=’0′ scrolling=’no’ style=’overflow:hidden’>,<,/iframe>, This kind of irregular boundary is relatively easy to measure, consists of arcs with known radius or cord lengths, and are called horizontal curves? Unlike maps that represent land-use, soil series or geological units, this type of map displays the varying surface in slope, aspect and surface curvature? It is a method for producing computer generated terrain maps and models that combines DEM and TIN methods, but places an attribute on the elevation of z value? This type of map represents a regular array of elevation points, and the map information can be sourced from satellite images, radar data and lidar images? This method for centering a point-based elevation in the centre of a raster cell splits a complete surface into square cells or irregularly shaped patches of roughly equal area? This method for centering a point-based elevation in the centre of a raster cell produces a poor contour map with missing data and often joins between patches? This method for centering a point-based elevation in the centre of a raster cell has to convert contour polygons by manually digitizing or raster scanning to an altitude matrix? This method for centering a point-based elevation in the centre of a raster cell often gives an unsatisfactory result because there is difficulty in placing breaklines (line features that represent changes of the land surface such as a stream, bridges, roads, etc.)? This method for centering a point-based elevation in the centre of a raster cell is the most common method used, which uses altitude matrices or TINs? On a topographic map, for maps with scales larger or smaller then 1:20,000, no more than 10% of the positions of well-defined points tested may be in error. This is? For vertical accuracy, it is specified that no more than ___ of the points tested can be in error by more than one half of the contour interval? On a topographic map, it is specified that points tested for error cannot exceed more than one half of the contour interval. This is? It is the vertical distance between contour lines, and it is determined by the purpose of the map and by the terrain being mapped? When selecting points for topographic mapping, this method divides the desired area into squares or rectangles, and the elevation is determined at the corners of each of these figures. This method is called? When selecting points for topographic mapping, in this common method the elevations are determined for key or controlling points and the contour lines are interpolated between them. The controlling points are usually thought of as those points between which the slope of the ground is approximately uniform. Which method is this? When selecting points for topographic mapping, this older method which is a simplified drawing of contour lines uses elevations that are equal to those of the desired contour, and these are plotted on a map and connected together to form the desired contour line. This method is called? In the Universal Transverse Mercator grid system, these lines are displayed parallel to one another and run from the pole to the equator? In the Universal Transverse Mercator grid system, these are straight lines whose distance from one another increases with their distance from the equator? With the UTM grid system, in order to avoid negative numbers the easting value is assigned a grid value of ______ at the central meridian of each zone? Source.
