2. Inclinometer - Wikipedia

   en.wikipedia.org/wiki/Inclinometer

   An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator , tilt sensor , tilt meter , slope alert , slope gauge , gradient meter , gradiometer , level gauge , level meter , declinometer , and pitch & roll ...

3. Tree height measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_height_measurement

   The clinometer and tape method, or the tangent method, is commonly used in the forestry industry to measure log length. [15] [16] Some clinometers are hand held devices used to measure angles of slopes. The user can sight to the top of a tree using such a clinometer and read the angle to the top using a scale in the instrument.

4. Tree volume measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_volume_measurement

   A variation of this method is to measure the complete angle taken up by the image of the trunk and divide it by 2 to get angle a. [citation needed] Trunk diameter measurement. A combination of a monocular w/reticle, laser rangefinder, and a clinometer [1] [2] can be used to do go from simple diameters to a full measure of trunk volume. A ...

5. Strike and dip - Wikipedia

   en.wikipedia.org/wiki/Strike_and_dip

   A compass is used to measure the azimuth of the strike, and the clinometer measures inclination of the dip. [2] Dr. E. Clar first described the modern compass-clinometer in 1954, and some continue to be referred to as Clar compasses. [10] Compasses in use today include the Brunton compass and the Silva compass.

6. Tree measurement - Wikipedia

   en.wikipedia.org/wiki/Tree_measurement

   In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description. If measuring a mountaintop forest of stunted trees only six feet tall, a girth measurement made at 4.5 feet would be meaningless.

7. Topographic Abney level - Wikipedia

   en.wikipedia.org/wiki/Topographic_Abney_Level

   The scale is reversible. As shown in the photo, it is set for measuring percent grade. The reverse measures degrees of arc. An Abney level and clinometer is an instrument used in surveying which consists of a fixed sighting tube, a movable spirit level that is connected to a pointing arm, and a protractor scale. An internal mirror allows the ...

8. List of measuring instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_measuring_instruments

   A pair of scales: An instrument for measuring mass in a force field by balancing forces. Balance; Check weigher measures precise weight of items in a conveyor line, rejecting underweight or overweight objects. Inertial balance; Katharometer; Mass spectrometers measure the mass-to-charge ratio, not the mass, of ionised particles. Weighing scale

9. Biltmore stick - Wikipedia

   en.wikipedia.org/wiki/Biltmore_stick

   It looks much like an everyday yardstick. With practice a Biltmore stick is considered to be exceptionally accurate, often within half an inch on diameters. Some foresters use the tool regularly, however, many prefer to use more accurate tools such as a diameter tape to measure diameter at breast height (DBH) and a clinometer to measure height ...
