It is easy to overlay a base map on a contour or surface wireframe map, allowing you to diversify your mapping and display geographic information in combination with the three dimensional data. You can load any number of base maps on a page for optimum manipulation of your data interpolation (eg. You can combine base maps with other maps in map overlays, or can create stand-alone base maps independent of other maps on the page. Surfer 12 Software can import maps in many different formats to display geographic information, including groundwater modeling. This process transforms your data interpolation (eg.kriging) into brilliantly colored models. And with Surfer 12 software's easy map contouring you can add color fill between contours to produce dazzling displays of your maps or groundwater modeling, or produce gray scale fills for dramatic black and white printouts. With help from and Golden Software's Surfer 12 software generating publication quality maps has never been quicker or easier.ĭisplay contour maps over any contour range and contour interval, or specify only the contour levels you want to display on the map. Virtually all aspects of your maps can be customized to produce exactly the presentation you want. Add base maps and combine map types to create the most informative display possible. Display your grid as outstanding contour, 3D surface, 3D wireframe, watershed, vector, image, shaded relief, and post maps. You can also use grid files obtained from other sources, such as USGS DEM files or ESRI grid files. Surfer provides more gridding methods and more control over gridding parameters, including customized variograms, than any other software package on the market. kriging) engine transforms your XYZ data into publication-quality maps. If it doesn't cross a topo-line don't make the profile cross one.Īnd there you have a basic topographic profile.Produced by Golden Software, Surfer 12 software’s sophisticated interpolation (eg. ![]() ![]() Then connect the points together to form on smooth curve.ĩ9% of all hills don't have flat tops so don't give yours one. Looking at the original contour lines, you can see that only two of them were marked, but since you can see that there are 5 lines between each marked line you can figure out that each line is 10 apart (also known as the "contour interval").Īfter the lines are copied and labeled you can then copy this onto a topographic profile. Next you take a sheet of paper and mark off each line that intersects the A-B line. When drawing a profile first you need a section of map that your going to draw your profile on. ![]() This is a fairly simple concept to understand and once understood is quick and simple to do. Essentially this is taking a view of a mountain from the top down and then drawing it from the side. The steeper the valley, the sharper the pointĪ topographic profile is taking a flat image of a topographic map and producing an image of the map from the side. When contours cross streams they always point upstream. Depressions are represent by circles with hash marks (short lines pointing towards the center of the circle) to differentiate them from hillsħ. Hills are represented by circles with the peak of the hill located within the smallest circleĦ. Uneven spacing indicates an inconsistent slopeĥ. Evenly spaced lines indicate a constant slope Closely spaced lines indicate a steep change in elevation Far apart lines show little or no change in elevation - hence a flat area, like in the middle of the map The spacing of the contour lines indicates the angle of the slope of the area: Although this often does not occur within the field of the mapĤ. Contour lines always join together to form a loop. Otherwise that would mean that one spot has 2 different elevations.Ģ. ![]() Since they connect equal points of elevation, contour lines can NEVER cross. Indiana Jones and the Chronology of Chaosġ.
