3. I want to convert lat/long to XY coordinates. I picked up this equation but can't get the desired output: x = r λ cos (φ0) y = r φ. The measurements of the two points are: point1 = (-37.8206195, 144.9837765) point2 = (-37.8193712, 144.9837765) Attempt The position is specified as Zone X Y as follows: 1501 636973.515 73077.180 (meters is assumed) 1501 636973.515m 73077.180m (meters) 1501 2089808.121ftUS 239754.527ftUS (US Survey Feet) 1501 2089803.941ft 239754.048ft (International Feet) Supported units of measur Following a request from a visitor, I added the option to convert to and from Geocentric cartesian coordinates (X, Y, Z). Here's how: - Long, Lat, h -> X, Y, Z: Select WGS84 left and right: WGS84_XYZ (geocentric) under 'International' menu; - X, Y, Z -> Long, Lat, h: Select left WGS84_XYZ (geocentric) and right: WGS84. Description */ // This function converts lat and lng coordinates to SCREEN X and Y positions function latlngToScreenXY(lat, lng){ //Calculate global X and Y for projection point let pos = latlngToGlobalXY(lat, lng); //Calculate the percentage of Global X position in relation to total global width pos.perX = ((pos.x-p0.pos.x)/(p1.pos.x - p0.pos.x)); //Calculate the percentage of Global Y position in relation to total global height pos.perY = ((pos.y-p0.pos.y)/(p1.pos.y - p0.pos.y)); //Returns the screen. Your display is quite small (640,480) so the resolution is not going to be so accurated anyways. If you consider the world as a 2d Map, the point of Latitude=0°0' and Longitude=0°0' is your X=0, Y=0, which is in the center of the display Pixel= (340,240) So that 179° and 89' = the border of the screen. You could apply
The reverse conversion is harder: given X-Y-Z we can immediately get longitude, but no closed formula for latitude and height exists. See Geodetic system . Using Bowring's formula in 1976 Survey Review the first iteration gives latitude correct within 10 -11 degree as long as the point is within 10,000 meters above or 5,000 meters below the ellipsoid x | y 12834.6278 | 3551.5214 12834.6689 | 3551.5184 12834.8509 | 3551.4267 12834.8004 | 3551.4605 and this is lat and lng inside of area A, the format of expected numbers. x | y 35.856770 | 128.576365 35.860748 | 128.57009 On the Map tab, in the Navigate group, click the Go To XY button to display the overlay in the view. Click the Go To XY button again to remove the overlay. You can do the following with the Go To XY tool: Input coordinates by typing them directly or pasting from another source Print. Email to a Friend. Report Inappropriate Content. IF you already have it in ArcMap simply create a new x,y fields (lat long) and use the right click on one of the new columns and select Calculate Geometry. If you don't have it in ArcMap use the X,Y to create the features and then do the above. For a MapPoint, I get its X/Y coordinate values That means that in one degree, there are 3600 seconds. When you realize that, the DMS to DD formula is obvious: Decimal degrees = Degrees + Minutes/60 + Seconds/3600. Let's convert the latitude and longitude coordinates of the Empire State Building. The coordinates are 40° 44′ 54.3″ N, 73° 59′ 9″ W
Geographic Information Systems: I need to figure out how to convert my X/Y-coordinates to longitude and latitude. I do not need the exact conversion, just an approximate so I can plot it in a mapping API. I managed to estimate the following X/Y to Long/Lat: (x, y) = 24050, 123783.3333 -> (long, lat) = (122.98, 24.46) (x, y) ~ Formula to convert X/Y to Long/Lat coordinates of given poin

Precision is not paramount. I would be happy if it were within a quarter of a km accuracy. I found.. To calculate the XY coordinates in the attribute table of a layer of points, you can do it with the Add XY Coordinates tool from ArcToolbox. The steps to complete the calculation coordinates are: Before starting, you need to have defined the respective reference system. From ArcToolbox, go to Data Management Tools> Features> Add XY Coordinates Moving a vertex to an exact x,y location (absolute x,y) You can move a vertex (or point) by specifying new x,y locations when you obtain additional data that provides the exact coordinate location at which the vertex should be Adress från sexagesimala lat long koordinater: fyll i de sexagesimala GPS-koordinaterna och klicka på den motsvarande Få adress -knappen.

Adding New X/Y Data to a Map Project from a Table. If you will be using geographic coordinates from an already existing table, make sure that the X value and Y value for your coordinates are listed in separate columns. If you have latitude and longitude coordinates, you can label them LAT and LONG in your table The coordinates of these locations are in the form of XY coordinates, and I would like to calculate the distance, in kms, between the two locations using geodist. To do the same, I have to convert the XY coordinates to Lat-Long coordinates. Appreciate any help to figure out how to convert XY coordinates to Lat-Long coordinates. Thank you
To add x,y coordinates to a map, you use the XY Point Data option on the Add Data menu as described in the steps below. This opens the XY Table To Point tool, which creates a feature class from the tabular data and adds a layer based on that feature class to the current map or scene Q: How does one gather the X,Y values from a point and place them within their MapInfo Table? A: Within the Update Column window use the command centroidx(obj) and centroidy(obj) respectively to get lat and long coordinates listed within the table. MapBasic -- Update *Table* Set *Column* = centroidx(obj This returns a Polygon string with XY coordiates where Geometry is the name of the column of Geometry data type: select Geometry. STAsText from ParcelTest where APN = '001-012-012' How do I get a Polygon() string containing lat/long points instead? The SQL needs to work with a query, not a stored procedure Using the Go To XY tool As you work with a map, you can easily change how you view the data it contains. When you're just browsing a map, you might want to pan and zoom around the data to investigate different areas and features Convert Latitude/Longitude to Decimal. The form below allows you to convert Latitude and Longitude information between decimal format and degree/minute/second (DMS) format

Convert forward and backward with the Convert XY and Convert Lat/Long buttons. Be aware that you must enter negative latitudes when the South Pole region is selected using the pull down menu (and the Convert Lat/Long button). Similarly, when entering latitudes between -60 deg and 60 deg you must select the Equatorial region wrf.ll_to_xy¶ wrf.ll_to_xy (wrfin, latitude, longitude, timeidx=0, squeeze=True, meta=True, stagger=None, as_int=True) ¶ Return the x,y coordinates for a specified latitude and longitude. The latitude and longitude arguments can be a single value or a sequence of values.. The leftmost dimension of the returned array represents two different quantities converting lat long points to UTM. Dear Colleagues, Good day! I have a data points collected using GPS..It was on latitude and longitude coordinate system.I wonder if there's any function in R where.. You need the lat/long of the upper left corner and for the lower right corner. Given those, you can convert any mouse click's x,y to a lat/long. There may be some trigonometry required at higher latitudes because of the converging of the longitude lines as you go north For instance: The following variables are passed into flash: Lat: 32.777654 Long: -79.933819. NOW, we need to translate that into an XY position inside the mc with the map graphic in it. I'm guessing this can be down with a mathematical conversion/equation but i have no clue how to do it

where you put in the pixel values for (x,y) and get (lat,long) for (X,Y). For example, the lower left corner values would give you u = Aa + Bb + C v = Da + Eb + F Using the lower right and upper left corners listed above will give you 4 more equations My data was not in the World Projection (as ArcMap calls it) so when I finally figured out how to access the x,y coordinates of the point, they were not in Lat/Long. So basically I reproject the file, extract the x,y coordinates, then reproject back to State Plane which is what I need. Not too elegant, but it gets the job done Here also we convert all the Lat/long from degrees to radians and the output type is same numpy.ndarray Numpy Vectorize approach to calculate haversine distance between two points For this we have to first define a vectorized function, which takes a nested sequence of objects or numpy arrays as inputs and returns a single numpy array or a tuple of numpy array
