You should see the surface, with points in red and white contours, since this is the standard style. The vertices of the triangles are spot elevations that may have been measured in the field by leveling, or in a photogrammetrist's workshop with a stereoplotter, or by other means. I tried to draw a polyline on civil 3D on the contour lines, when I import as DXF through background layers into watergems, and I turn the bing map on, THE LINE ITS COMPLETLY ELSEWHERE ON SOME RANDOM OCEAN.

This is why nothing shows in WaterGEMS. 2. Thanks. Finally, draw your contour lines. I have now drawn the contour lines manually, but it's a very easy 'procedure' so there must be some kind of automatic way to do this, I guess? Pasted as rich text. A general way to draw contour lines is to determine the values of f(x,y) at regular intervals of x and y, creating a grid of values. Keep in mind the following characteristics of contour lines (Rabenhorst and McDermott, 1989): How does your finished map compare with the one I drew below? Finally, draw your contour lines. You should make separate photos for the different detail classes. For information about 3. -> SAVE AS DXF, During this process the contour lines cover the area to be designed so everything is OK. (Confirmed using the maps on civil 3D). If you are lucky the jpg has a design and resolution which makes it easy to autotrace (with the right settings), but if it is to blurry or complex there is no way Illustrator will ever guess all the finer details from the chunky pixels. To change other contour In general, contour intervals increase in proportion to the variability of the terrain surface. A useful characteristic of TINs is that each triangular facet has a single slope degree and direction. I believe I created a PDF file of the contour lines, then used a PDF to DXF conversion software to convert it to a AutoCAD file, and then imported and superimposed those lines onto my drawing. What PHILOSOPHERS understand for intelligence? Step 1: Open Google Earth and create a placemark, path or polygon, or simply load an existing KML/KMZ file.

Lutz | To assign elevations to polylines from a contour layer in AutoCAD products use the steps: In a new drawing with a coordinate system assigned, use the 'MAPIMPORT' command to bring contours into the drawing. You are unable to export contour lines correctly into SketchUp from CAD using the Send Layer button in the Land F/X SketchUp Connection. Related to this element of subjectivity is the fact that the fidelity of a contour map depends in large part on the distribution of spot elevations on which it is based. There is Grid Math option for regression equations and creating thematic grids, for example . How can I make inferences about individuals from aggregated data? view an image of an irregular array of 16 spot elevations, Chapter 6: National Spatial Data Infrastructure I, Chapter 7: National Spatial Data Infrastructure II, Repository of Open and Affordable Materials, Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, John A.
