![]() Create Spot Elevation Points and Minimum and Maximum Elevations If the saddle depth is greater than the Minimum Saddle value, both peaks will be retained. If multiple peak candidates are identified within the same key contour and are within the Maximum Distance value of each other, the saddle depth between them will be analyzed. ![]() Peaks sharing a key contour that are further from each other than the Maximum Distance value will be identified as peaks. The first closed contour containing a peak candidate is referred to as a key contour. The Minimum Concentric Contours value describes the minimum number of closed contours nested within each other that are needed to define a peak candidate. This option will generate point features at local peaks found based on user provided parameter values. Note that the contour lines willīe generated so that the higher elevations are to the left of the contour To the Gridding tab options to export contours directly to package files, To export the contours directly to a package file can be used in addition To generate a large number of contour lines over a large area, the option ![]() Select this option to add additional vertices along the generated line and area features to improve their appearance. The user to control how terrain layers are sampled during contour generation. Resolution at which the loaded terrain data is sampled to generate the contour lines. The resolution in the x and y directions control the Used to restrict which contour lines are generated (by default all loadedĮlevation values are considered). Check the box to Only Create Lines at Specified Height to generate contour lines only at the height specified by the Contour Interval value. This option allows the user to set the contour interval as well as the major and min or contour interval multipliers. Options dialog (pictured below) which allows the user to set up The command displays the Contour Generation Choose this option from the Analysis Menu, or the Analysis Toolbar button. ![]() It is also including the next index line.Grid) command allows the user to generate equally spaced contour linesįrom any loaded elevation grid data. Thus maps generally count five contour lines from one index line to the next one. To calculate the contour intervals start by counting the contour lines from one index line to the next one. Note: If the uphill elevation is equal to 1,000 units above the average sea level with the lowest elevation of 800 units above average sea level, then the difference in elevation will be equal to 200 units. For keeping the contour map simple and easy to read, all such contour lines are marked with their elevation reading. These marked or labelled lines are termed as Contour lines of the index.Īdditional Information: The contour maps are consisting of the contour lines for the geographic region. Contour interval is the vertical distance between the two contour lines and these lines are next to each other. Also, a higher contour interval is needed for the large area and a small contour interval for the small area.Ĭomplete answer: Contour lines are the lines for joining points of equal height above or below the sea level. ![]() While a large area is to be mapped onto the small piece of paper, contour intervals are useful. This elevation is in between the two contour lines on a topographic map. Hint: A contour interval in the survey about the vertical distance or sometimes as the difference in its elevation. ![]()
