Finds the exact point that lies halfway between two or more places. Find your personal center of gravity--the geographical average location for all of the places you have lived in. See the results on a Google Map. Using the calculator FAQ

This calculator currently can only be used with the latitude/longitude option to find the coordinates of the midpoint. You can find the latitude and longitude for addresses and cities at: Geocode Finder

The calculator calculates the geographic midpoint based on the assumption of a spherical earth. The geographic midpoint for any two points on the earth's surface is located halfway along the great circle route which is the shortest route that runs between both points, and would be like stretching a string between the two points on a world globe then finding the middle of the string. The geographic midpoint for three or more points on the earth's surface is the center of gravity (center of mass or average location) for all of the points.

To help visualize the concept of center of gravity, imagine that a small weight is positioned at the location of various cities on a world globe. Now imagine that the globe is allowed to rotate freely until the most heavily weighted part of the globe is pulled by gravity until it is facing downward. The lowest (and heaviest) part of the globe is the center of gravity and the geographic midpoint for all of the weighted cities. See Calculation methods for a detailed description.

The Calculator is used in three different ways. First, it is used to enter fixed stations locations. Second, it can be used as a stand-alone calculator for converting coordinates between different systems. Finally, it can be used to calculate the magnetic declination for a particular survey.

I've just succeeded in getting the area of a polygon using field calculator. The polygon was drawn on a Google hybrid aerial photo. There are no units given in the calculation and I assume the area figure is based on latitude / longitude. How do I go about changing the projection in order to get an area figure in hectares?

This AP Human Geography score calculator uses the official College Board scoring worksheets from previously released exams, making it highly accurate and up-to-date. Using this calculator can also help relieve your stress on exam day; you will know how many points you need to get to earn the score you want.

If you know of another plate motion model, possibly recently published, that uses a no-net-rotation (NNR) framethat you would like included in this calculator, please contactsoftwareunavco.org.

Once you get the feel for a single point entry, you can try multiple point entry.There are three important things to remember. First, each set of values for a location,whether in geographic or cartesian coordinates, must be separated from the othersby a comma. Second, if you are using geographic coordinates, a height value (even ifzero) must be supplied. Anything after the third coordinate (height if geographic,Z if cartesian) and before the comma is taken an optional site name. So, forgeographic multiple point entry, your entry could look like:

Results for the geographic poles, 90N and 90S, will be correct but the east and northcomponents of the velocity vector depend on the longitude given. To convince yourself,step back from the geographic pole a little, say, to 89.99N or 89.99S, at the same longitudeand repeat the calculation.

Care must be taken when comparing a specified plate between different models,because which plates are defined or have defined angular velocities varies from modelto model. The Auto plate selection of the calculator uses 15 plate boundariescorresponding to the NUVEL 1A model (bold in the table below). You can get ASCII filesof these boundaries from  .Using the table below, then, the Antarctica plate (AN) of NUVEL 1 corresponds to thecombined Antarctica (AN) and Scotia (ST) plate of NUVEL 1A. Likewise, the combinedAustralia (AU) and Capricorn (CP) plates of the GSRM correspond to the Australia (AU)plate of the other models. In certain models, some plates have no defined angular velocity,e.g. the India (IN) plate in the APKIM2000 model. This leads to two important points:

HS2-NUVEL1A and HS3-NUVEL1A: Technically these models are not published in a NNR frame,since these represent the plate motions relative to fixed "hotspot" frames. In order to makethis calculator function more logically, however, these models are also provided here in a NNR framewhereby the following "hotspot frame - NNR frame" rotations have been applied:

From this calculator, you should obtain about the same site motion for the NUVEL 1A model in the NNR frame andHS2-NUVEL1A model rotated into the NNR frame; the difference is mainly due to rounding errors usingthe various model parameters tabulated in different units, including the parameters forthe "HS2 hotspot frame - NNR frame" rotation above.

Structural and dynamical features of the ionised and neutral upper atmosphere are strongly organised by the geomagnetic field, and several magnetic coordinate systems have been developed to describe this organisation. Here we provide a quasi-dipole geomagnetic coordinate calculator (Emmert et al, J. Geophys. Res., 2010) using coefficients for all spherical harmonic degrees (up to 13) of the 13th Generation International Geomagnetic Reference Field, and for comparison, a simple tilted dipole coordinate calculator using only the degree 1 coefficients of IGRF-13. Locations which have similar geomagnetic latitudes are likely to experience similar levels of magnetic disturbance. Local time and conductivity structures also influence magnetic disturbance levels.

In 2003 the living wage calculator was created by Amy Glasmeier and Tracey Farrigan. Over time, as data sources change or new sources become available, the tool is enhanced to consider basic changes in the consumption patterns of Americans. The last significant adjustment occurred in 2010, with the change of health care composition and miscellaneous expenses.

This year utilizing data from 2019-2020, we made three changes: a change in geographic scale, an element composition change, and the inclusion of a new cost element. We made one-off decadal adjustments in the scale of childcare costs. The composition of telecommunications now includes cell phone and broadband services, and we added a cost element to enable individuals and families to engage in civic activities.

Please note. During the first month of a new data posting (postings occur during the first quarter of the new year), our users sometimes identify anomalies. We follow a standard practice of verifying an anomaly. First, we track the anomaly back to the tool's computer code. Second, we review the underlying data and data description for the possibility of subtle changes arising in the data source. Finally, we trace the anomaly back to its geographic origin to determine whether there are underlying geographic changes in the posted data. Like all federal data agencies, we post initial findings and make adjustments over the first month.

The number of significant figures reported by the expression calculator can be controlled in Tools | Program Settings on the Compute tab. The program setting is called Expression calculator precision. The valid range for the setting is 1 to 5 significant figures. The program uses a default value of 3 unless modified by the user.

As before, the MRTN and most profitable N rates determined from the calculator are directly the total N fertilization amounts for each rotation, with no need to further adjust rate for the previous corn or soybean crop. Rates from the CNRC will now match those in Iowa State University Extension and Outreach Publication CROP 3073, Nitrogen Use in Iowa Corn Production.

Companies such as Ikea have used the calculator to set the floor under wages at their stores around the U.S. Many government officials rely on it to set wages and policies. Minimum wage activists, union organizers, and thousands of individuals have turned to the calculator to help negotiate wage increases.

Glasmeier's concerns about income inequality and interest in how resource availability is affected by geography inform much of the work of her Lab on Regional Innovation and Spatial Analysis (LRISA). With the growing array of tools built around Geographical Information Systems (GIS), economic geographers at LRISA can examine trends from a geographic perspective or model processes and see how they change over time. "We analyze information that describes the world spatially," Glasmeier says.

In the early 2000s, Glasmeier received a grant from the Ford Foundation to take a closer look at the distribution of poverty across the U.S. As part of the project, she developed MIT's first Living Wage Calculator in 2003. At the time, the calculators available from the University of Washington in Seattle and at the Economic Policy Institute (EPI) did not fully meet her research needs. Glasmeier integrated parts of the EPI design, but the LWC was largely developed from scratch, in order to add a spatial perspective and embed the calculator in an economic development tool kit. 2351a5e196
