| Topographic maps use contour lines based on elevation to depict landforms. |
|
| Topography is depicted on maps by contour lines, hypsometric tints, and relief shading. |
|
| Topographic maps show vertical data with contour lines, hypsometric tints, spot heights, and relief shading. |
|
| In the pass and above ridges, movements often did not follow contour lines and it was difficult to discern any influence of local topography on direction of movement. |
|
| Without the use of land-surveying instruments, she and her neighbours were able to put the bunds along the contour lines of the slope. |
|
| Generally, bathymetric maps show depths by contour lines and gradient tints. |
|
| To make things as simple as possible I decided to concentrate on images of flat emptiness, avoiding mountainous areas where the contour lines jostle against each other. |
|
| This pose is all about showing off your contour lines, specifically bronzer and highlighter. |
|
| Her contour lines are deliberately broken, in the same way that her lines of pseudo-Freudian dialogue are intentionally disjointed. |
|
| So does workaday service to sculpture, in studies rather than pictures: hard contour lines popping images off the paper. |
|
| Buache was also a pioneer in the use of contour lines to express relief on maps. |
|
| He indicates a small arrow in the middle of an ocean of contour lines. |
|
| It may happen that the contour lines are far apart, but that the gradients are not very important. |
|
| On one of the mounted maps, cut out the areas inside of the closed 522-decameter contour lines. |
|
|
|
| The wave pattern of most contour lines consists of topographic ridges and troughs, that is, elongated crests and depressions, respectively. |
|
| However, an actual'image of the drumlins is much easier to interpret and more visually meaningful than looking at a mass of contour lines. |
|
| Ask them to refer to Harris' sketch for use of contour lines and crosshatching. |
|
| Drumlins become apparent by examining the contour lines of the topographic map for the Peterborough area. |
|
| For filling in the areas work well up to the contour lines, because everything needs to be filled. |
|
| The engineering or detailed flood risk maps are topographic maps that show contour lines of equal elevation and spot elevation data. |
|
| The contour interval of a contour map is the difference in elevation between successive contour lines. |
|
| So, when I say that hedgerows are planted on contour lines not more than two metres apart, I mean that there should be a vertical drop in height of less than two metres between one hedgerow and the next. |
|
| Also, while the contour lines provide a representation of height, on the image map the actual land cover of the drumlins can be seen along with the effect they have on the surrounding land use. |
|
| Hypsography depicts a 3-dimensional landscape and its landforms, with the spatial features of this theme being contour lines, bathymetry lines, form lines, and spot heights. |
|
| That was a lesson in reading contour lines. |
|
| Other contour lines are also relatively horizontal. |
|
| Within the rural development plans, some Member States facing erosion risks included practices such as tillage following contour lines, while some with low soil organic matter have banned the burning of cereal stubble. |
|
| Ask students to pay attention to contour lines and emphasis in the sketch. |
|
| It contains all the higher detail in the nontopo version, but the addition of topographical contour lines makes it great for hikers, aviators and hunters. |
|
| It consisted of covering slopes with bench terraces parallel to contour lines, with each terrace containing a crop row, an infiltration ditch and a earth bank and often planted with trees. |
|
| Meteorological contour lines are based on interpolation of the point data received from weather stations and weather satellites. |
|
| In cartography, the contour interval is the elevation difference between adjacent contour lines. |
|
| In economics, contour lines can be used to describe features which vary quantitatively over space. |
|
| Lines of constant tidal phase are called cotidal lines, which are analogous to contour lines of constant altitude on topographical maps. |
|
|
|
| The solid green contour lines represent cavity one and the dotted contour lines represent cavity two. |
|
| The kids love this analogy and it forces them to remember to not lift their drawing pencil and focus on making their contour lines continuous. |
|
| In the systolic and diastolic phases of heartbeat, two contour lines were drawn to delineate the endocardium and epicardium. |
|
| Some of the lines have numbers on them so you can quickly tell whether you are going up hill or down hill when cutting across the contour lines. |
|
| When maps with contour lines became common, the idea spread to other applications. |
|
| In 2007, Pictometry International was the first to allow users to dynamically generate elevation contour lines to be laid over oblique images. |
|
| If there is little or no content on the base map, the contour lines may be drawn with relatively heavy thickness. |
|
| Sometimes a sheen or gloss is used as well as color to set the contour lines apart from the base map. |
|
| Numerical marking is the manner of denoting the arithmetical values of contour lines. |
|
| This can be done by placing numbers along some of the contour lines, typically using interpolation for intervening lines. |
|
| However, if the contour lines cycle through three or more styles, then the direction of the gradient can be determined from the lines. |
|
| When referring to geographic features such as mountains on a topographic map, variations in elevation are shown by contour lines. |
|
| By around 1843, when the Ordnance Survey started to regularly record contour lines in Great Britain and Ireland, they were already in general use in European countries. |
|
| A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. |
|
| The gradient of the function is always perpendicular to the contour lines. |
|
| The diverse terrain of Afghanistan is represented in a hand-drawn style by applying dots to contour lines that are easily created from digital elevation data. |
|
| Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real or hypothetical surface with one or more horizontal planes. |
