The drap allows a rapid and simultaneous measurement of dip and azimuth of dip of a fracture plane. A Bureau of Mines direct-reading azimuth protractor / By D. (Douglas D.) Bolstad and joint author. Abstract A procedure is described for constructing a direct-reading azimuth protractor (drap) that is a variant of the drap described in Bureau of Mines Information Circular by D.

Bolstad and M. Mahtab. The NPR Plotter with Rotatable Azimuth Compass Rose is a top of the line plotter. It features four protractor scales and fourteen nautical and statute scales for Sectional, WAC, and Terminal Charts.

In using the semicircular protractor, when point B is to the left (west) of point A. The protractor must be reversed so. As I mentioned, the Protractor was a little exe but it's a hell of a lot cheaper than buying Digital Setting Circles.

I hope you like my Azimuth circle project and if you have any questions, post them to me (or in the forum) and I will try and answer them. Article by Denis. Discuss this article on the IceInSpace Forum.

Look at the diagram. Consider the direction in which the green arrow is pointing. To get its azimuth, you measure the angle it makes with 0°. That angle is ° (shown in parentheses). To get its compass quadrant bearing requires three steps. First, decide whether the arrow is closer to N or to S.

You can see it's closer to the S. I received Azimuth, as well as Zenith (The Interscission Project: Book One), through the Goodreads Giveaway Program. These are the first books I will have read by this author.

Cut out the protractor and use by lining up the zero degree line with a true North-South line. With the penalty of decreased accuracy, line up the degree line with a line of latitude.

“Today, I took the bearings of some structures belonging to the United States Bureau of Mines above which the trail appeared.

Its direction was approximately N. 30° E. The trail was almost exactly vertical as seen in projection; it extended from about 40° to about 25° above the horizon, widening from the top to, say, 30° above the hori.

Real Reading 3: Creating an Authentic Reading Experience (mp3 files included) by Bonesteel, Lynn and a great selection of related books, art and collectibles available now at Target Grid.

The target grid is a circular paper device on which grid lines are printed. Normally, the target grid used is DA Form (Target Plotting Grid, Field Artillery).

Grid lines on. The index mark is the center of the protractor circle from which all directions are measured. Figure Types of protractors. The military protractor, GTAcontains two scales: one in degrees (inner scale) and one in mils (outer scale).

This protractor represents the azimuth. The RM protractor as can be seen in the picture here comes with an elastic string that is tied around the outside edge of the protractor for azimuth measuring.

Even with a string, the square edge makes it necessary for angled tick marks to be the source of the reading; a round compass rose trying to be read off a square piece of plastic. Suite2/F., Hewlett Centre, Hoi Yuen Road, Kwun Tong, Kowloon, Hong Kong/5().

Since there are 60 minutes in a degree you can get to within 1/12 of a degree. Although this level of precision is typically unnecessary in woodworking, an instrument of this caliber is pleasing on its own merits. THE TOOL ITSELFFile Size: KB.

The compass direction of a directional survey or of the wellbore as planned or measured by a directional survey. The azimuth is usually specified in degrees with respect to the geographic or magnetic north pole.

Bureau of Mines. An offshoot of a similar process for recovering gold, the electro-oxidation technique uses electricity to oxidize the mercury minerals, after the ore has been mixed with brine, so that the mercury can dissolve.

The metal then can be precipitated out of solution simply by adding powdered zinc or iron. Reading an angle on a protractor differentiated.

Summary of Altitude-Azimuth Project: One method which has been used frequently and successfully to better measure Altitudes is to buy a large protractor (these are available at some stores, such as Art Supply Warehouse, in sizes up to a foot in diameter).

Glue a fat drinking straw to the protractor, with the straw going through the 90 and. Then a protractor is used to measure the angle between grid north and the drawn line.

This measured angle is the grid azimuth of the drawn line (fig. When using an azimuth, you imagine the point from which the azimuth originates as. Figure Azimuth angle. Figure Origin of azimuth circle. Figure Azimuth and back azimuth.
