| One of the easiest ways to create a TIN for a small area where a paper contour map exists is to use this tools and follow the steps outlined below:
| | #REDIRECT [[WMS:Creating TINs]] |
| | |
| #Scan the paper map and save it as a TIFF (*.tif) image.
| |
| #[[Registering an Image|Register the image]] (you may want to mark the map with your register points prior to scanning it).
| |
| #Set the vertex options to digitizing mode in the [[WMS:TIN Options|TIN Options]] dialog.
| |
| #In the z edit box of the edit window set the z value to the desired contour value.
| |
| #Using the Create Vertex tool, digitize or [[WMS:Vertices|create vertices]] along the specified contour value (the spacing of points along the contour lines should be approximately the same distance as the spacing between adjacent contours).
| |
| #Repeat steps 4 and 5 for each contour line. Spot elevations can be entered by setting the z value to the value of the spot elevation and then creating a vertex at that location. | |
| #[[WMS:Triangulating|Triangulate]] the vertices once you are done.
| |
| | |
| Of course, this method is awfully tedious for larger areas, but is ideally suited for smaller areas where there are not many contours
| |
| to be digitized.
