The earth isn't perfectly round, it isn't even a perfect ellipsoid, and slightly differentshapes work better for some regions than for the earth as a whole. The latitude of F is called the footprint latitude.įP = E = grid distance from central meridianĬ = convergence of meridians = angle between true and grid northĪnother thing you need to know is the datum being used: Datumĭon't interpret the chart to mean there is radical disagreement about theshape of the earth. Or better yet, a Javascript page.į = foot of perpendicular from P to the central meridian. It would sure benice if someone wrote a spreadsheet to do this. This will get very complicated, but themath, although tedious, is only algebra and trigonometry. (Before satellites, observing thosedifferences was a principal method for determining the exact shape of theearth.) Converting Latitude and Longitude to UTM For other latitudes multiply by cos(lat).Distances for degrees, minutes and secondsin latitude are very similarand differ very slightly with latitude.

GeologicalSurvey Professional Paper 1395 and U. Previously, the two basic references for converting UTM and geographic coordinates wereU.S. Also, old World War II era maps of Europe apparently used a single gridfor all of Europe and grids in some areas are wildly tilted with respect tolatitude and longitude.

I saw US military maps of Germanyshift their UTM grids by about 300 meters when a more modern datum was used forthe maps. This means that different maps will have different grids depending on thedatum used (model of the shape of the earth). UTM grids, on the other hand, are created by laying a square grid on theearth. But there is no way to determine your UTM coordinatesexcept by calculation. If you can see the stars andhave a sextant and a good clock set to Greenwich time, you can find yourlatitude and longitude. Latitude is determined by the earth's polar axis.Longitude is determined by the earth's rotation. Let's see now this tool that does the same process in reverse, that is, having coordinates in UTM format (Universal Traverso de Mercator) and knowing the area, transform them to latitudes and geographical longitudes.Ĭaution! Unlike latitude and longitude, there is no physical frame ofreference for UTM grids. In the previous post we had shown an Excel sheet to convert coordinates Geographic to UTM From a sheet that had popularized Gabriel Ortiz.When I use the function to convert degree in DMS in the excel, as the follow below, in the visual basic, someone knows how can I increase the number of decimal places for the seconds? Converting coordinate DD to DMS in Excel (increase the decimal number for the seconds) Please community and friends.

I get enough inquiries on this subject that I decided to create a page forit. – Conversion of Coordinates in Degrees, Minutes and Seconds to Decimal Degrees. – Conversion of Coordinates in Decimal Degrees to UTM.

Download the free Excel template to perform the following operations: – Conversion of UTM Coordinates to Decimal Degrees. To convert into various coordinate formats, we freely offer our Excel template.

Is there an easier way than manually converting each decimal degree to UTM and and entering them manually. To be more specific I need to have one column that shows the UTM on showing the x and one showing the y. I need to show the coordinates as utm x y. HI I have an excel spreadsheet that shows the coordinates in lat long decimal degrees.
