So you have to apply tan (lat) and then multiply with the same scale factor as in x-direction. But with increasing latitude, parallels must be spread wider and wider in order to maintain angular correctness. (b) Now the latitude: At the equator, the latitude is mapped to the y-axis by the same factor as you used for the longitude. Choose that factor in a suitable way such that the desired longitudinal range fits on your window. (a) Map your longitude to the x-coordinate by simple multiplication by a scale factor.
Converting xy coordinates to latitude longitude code#
To write the code for that projection is usually the easiest part and more or less straight forward. Then decide, which projection would be most suited for your application. Example are: Cylindrical, Conical, Conformal.
And for mapping the surface of a sphere to a plane there are many alternatives, each of them having their specific advantages and disadvantages. What you are looking for is a so-called projection. I just read that the minutes and seconds are divided in 90 Units not in 60 as I was supposing.
If you want to do it anyways, the only thing you have to do is to add the seconds to the formula. 360*2 = 720 and 720>640 so you are already not going to be able to accurately represent points in less than 35 or 40 Minutes scale. In 640x480 Resolution of display, you are not going to have any difference considering the seconds or not. For example, suppose you locate an object 10 meters west and 20 meters north of a sensor at (lat, lon) (45.000100, 6.500000) and the building's center is at latitude 45 degrees. The minus (-) in Y is because North coordinates are positive, but you need to decrease the pixels to go upwards because the Pixel (0,0) is in the upper-left corner. I consider the format of your 2nd comment (Positive to north and east). Since you mentioned that you want it in a sort of 3d cylinder then you can use the principle of solution 2 and apply part of my "thinking" to make the scales adapting it to your view-model. So that 179° and 89' = the border of the screen. If you consider the world as a 2d Map, the point of Latitude=0☀' and Longitude=0☀' is your X=0, Y=0, which is in the center of the display Pixel=(340,240) Basically, I need a Javascript script that receives the latitude and longitude of a frame and returns the position (x,y) for that frame (in relation to frame 0 with position. Type coordinate pairs on separate lines or paste latitude and longitude. Frame (Frame 0) needs to be point (0,0) and I want the following ones to be converted to XY Coordinates as well. Your display is quite small (640,480) so the resolution is not going to be so accurated anyways. Use this tool to convert geographic coordinates from DDMMSS to decimal degrees. I am supposing that you don't need the Z-Axis Probably this is not going to be the best approach as well but. We hope this guide has been helpful in your data science journey.I had deleted the solution because I thought it was not "professional", but seeing your comments to other questions. The UTM zone number and letter can usually be found in the metadata of your geospatial data. Remember to replace the UTM zone number and letter in the conversion function with the correct values for your data. This conversion is essential for many geospatial data analysis tasks and can be easily integrated into your data processing pipeline. ConclusionĬonverting UTM to longitude and latitude in a Pandas DataFrame is a straightforward process with the help of the Pyproj library. Now, df_latlon is a new DataFrame with columns ‘Longitude’ and ‘Latitude’ representing the converted coordinates. Df_latlon = convert_utm_to_latlon ( df, 33, 'U' ) # Replace 33 and 'U' with your UTM zone number and letter
