Mysterious Lat Long conversion to XY problem using QGIS

How do you convert XY coordinates to latitude and longitude in QGIS?

Toggle editing (ctrl-E) and open the calculator (ctrl-I). Select “create a new field”, call it “Longitude”, and make the expression $x. Do the same for a second new attribute called “Latitude” and make the expression $y. You should now have latitude and longitude in your attribute table.
 

How do you convert XY coordinates to latitude and longitude in GIS?

To convert coordinates, complete the following steps:

1. On the ribbon, click the Map tab.
2. In the Inquiry group, click Coordinate Conversion. .
3. In the Coordinate Conversion pane, click Map Point Tool. and click a location on the map.
4. Enter coordinates in the Enter a coordinate text box and press Enter.

How do I change latitude and longitude in QGIS?

QGIS defaults the CRS to that of the project. With the latitude and longitude coordinates in decimal degrees, the CRS needs to be set to WGS 84 (EPSG: 4326). To do this, click on the tiny globe icon located to the right of the drop down menu for Geometry CRS. From the CRS list, select WGS 84 and hit the “OK” button.
 

How does QGIS calculate Lat Long?

formulas from above links: longitude= x(transform($geometry, ‘EPSG:FROM’, ‘EPSG:4326’)) and latitude = y(transform($geometry, ‘EPSG:FROM’, ‘EPSG:4326’)) for WGS84 lat/long.

How do you get XY coordinates?

To find out the coordinates of a point in the coordinate system you do the opposite. Begin at the point and follow a vertical line either up or down to the x-axis. There is your x-coordinate. And then do the same but following a horizontal line to find the y-coordinate.

How do you convert XY coordinates to shapefile?

How do I create a shapefile from Latitute/Longitude Coordinates?

1. Open ArcMap.
2. Open the Catalog Pane* and navigate to your file (can be a .
3. Right click on your file and hover over “Create Feature Class”, then select “From XY Table…”
4. In the pop-up window, the X Field should be Longitude and the Y Field should be Latitude.

How do you convert latitude and longitude to grid reference?

So to convert a (WGS84) latitude/longitude point to an OS grid reference, it must first be converted from the WGS84 datum to the OSGB36 datum, then have the transverse Mercator projection applied to transform it from a curved surface to a flat one.

Are latitude and longitude XY coordinates?

If you place x and y axis on earth, Latitude will cut across y axis and Longitude will cut across x axis. Hence, Latitude is y and Longitude is x.

What is the difference between latitude longitude and XY coordinates?

Quote from video:

How do you convert XYZ to polar coordinates?

To convert from Cartesian Coordinates (x,y) to Polar Coordinates (r,θ): r = √ ( x² + y² ) θ = tan^–1 ( y / x )

Are XY coordinates the same as latitude and longitude?

No, both are only labels or variable names for some coordinates, but lat/long are for geographic coordinate systems while xy is more common reference to planar (or 3D) coordinate system.
 

How do you convert geographic coordinates to projected coordinates QGIS?

There are three different ways to change/manipulate projections in QGIS:

1. Project Properties > CRS (or you can click on the icon where EPSG is written in the bottom right corner)
2. Right click on vector layer > Set Layer CRS.
3. Right click on vector layer > Save As
