Operation principle

Contour interpolation device 9 is using: step 1: on the geography line of measuring according to field operation or domatic adjacent two isocontour elevations, promptly measure geomorphic feature point A, B, these 2 is end points a, b then, the line segment ab between 2 of draftings on the figure; Step 2: according to the depth displacement of 2 of A, B, a certain horizontal line in the contour interpolation device in this patent is placed on a point height value units correspondence position, around a point rotation contour interpolation device, makes the b point just be positioned at b point height value units correspondence position then; Step 3: treat geography line ab two-end-point in the relevant position of contour interpolation device to after good, draw on ground shape line according to the linear position of contour interpolation device hollow out that each bar is isocontour to be passed through a little.The contour interval of the regulation of different proportion chi is slightly different, and (vast scale topographic map contour interval commonly used is 0.5m, 1m at 1: 500; Be 0.5m, 1m, 2m at 1: 1000; Be 1m, 2m and 2.5m at 1: 2000, is example with 1m, and 2m then paints one every a choosing, one of interpolation again after 0.5m then paints, other contour intervals are analogized apart from this), the contour that promptly obtains the corresponding elevation of AB geography line passes through a little; Step 4: repeating step 1-3, then identical the passing through of elevation on the topographic map a little coupled together with smooth curve, promptly obtain a curve of representing differing heights.

The use of machine plotting device under the different coordinates: 1) under rectangular coordinate system, use rectangular co-ordinate machine plotting device: step 1: according to the longitudinal and transverse coordinate figure that known P is ordered, at first determine this in which grid of map sheet, in that grid, put on display the position of point again; Step 2: calculate coordinate difference Δ x, the Δ y of P point and nearest longitudinal and transverse coordinate line, turn to reading on the machine plotting device according to engineer's scale.Make two linear foots (the 5th graduation mark 6 and the 6th graduation mark 7) X-axis of aliging respectively (vertically) direction on the machine plotting device and find the Δ X coordinate position of this point on the corresponding diagram, find putting the coordinate figure position of Δ Y on Y-axis (laterally) direction at machine plotting device the top crossfoot (first graduation mark 4) simultaneously, this point is the detail point coordinate that P is ordered.But plotting goes out the whole detail points on this map sheet as stated above.2) use semicircle polar coordinates machine plotting device 8 under polar coordinate system: step 1: the home position with semicircle transparent panel 8-1 is limit O.When reality is surveyed and drawn, with a control point M as O point (this point also claim survey station point), with another control point N orientation (being the Ox direction); Step 2: adopt the semicircle polar coordinates machine plotting device 8 of indication angle, tolerance when making polar angle and vector, with direction with apart from the position of representing on the plane any, but plotting goes out whole control points as stated above.During concrete operation is that theodolite (or total powerstation) is placed on the M of control point, with another control point N is orientation point, the subpoint O that semicircle polar coordinates machine plotting device 8 is ordered with M on figure is as limit, with the bearing of trend of the subpoint of another control point N on figure as pole axis.When theodolite (or total powerstation) records an angle when (degree every minute and second system) and a horizontal range, then semicircle polar coordinates machine plotting device 8 is with the identical identical angle of direction rotation, and on straightedge rule (second graduation mark 5), find this point in proportion, and draw this point, be the detail point of surveying.
