Magnetic Declination Calculator. A declination calculator based on a magnetic reference field model can be used to calculate magnetic declination for any desired location (latitude / longitude) and time. The models are typically updated every five years, therefore the ones adopted in 2010 are valid until 2015.

Depending on the method used to finding elevation grade, it can expressed in different ways like decimal, percentage and degree. How to Calculate Elevation Grade. Before you figure out elevation grade, elevations must be taken from the starting and ending points for comparison, as well as the starting and ending distances.
Hi, Has anyone managed to setup a survey that calculates road distances between two towns ? Ideally, the user would insert in two text fields the name of the cities and then "it" would calculate the distance.

Step 2. Calculate the inverse from south to offset point: N 11°03'05" E ~ 130.42' Step 3. Right or Left? It can be seen that the bearing from south to offset point is left of the bearing from the north point, therefore the offset is to the left. Step 4. Calculate the difference between the bearings: 10°45'00" Step 5.

I have an excel spreadsheet with header and survey drill data. Header data contains hole ID, and location coordinates, and the survey data contains related downhole survey with Distance, Azimuth and Dip values. Since I know the hole location and surface elevation, I would like to be able to convert the survey table to XYZ coordinates as well.

Luckily there is a method that allows you to calculate apparent dip from true dip if the ... faces, road cuts, etc.) are very unlikely to be parallel to the true dip of the geological surfaces you are interested in. What is observed in these cross sections is the apparent dip ...
So, to calculate an average sale rate, add up the total amount spent and divide it by the number of answers you received. For example, if your total is $50,000 and you heard from 1,000 customers, then your average sale is $50. Now you are on your way to better understanding online survey results and how to read them.
To calculate a TST true stratigraphic thickness, transgressive systems tract requires survey information as well as some measure of the dip of the beds. Dip can be derived from dipmeter logs (with some caution) or from maps of geological structure.
In magnetic survey …sometimes the magnetic inclination, or dip, and declination (departure from geographic north) at several stations. If the object of the survey is to make a rapid reconnaissance of an area, a magnetic-intensity profile is made only over the target area.
