If you approximate the earth's surface as a sphere, then the formulae should be.

I have a large set of latitude and longitude coordinates and I need to convert each latitude and longitude to a set of X and Y (and possible Z) coordinate to display on the screen.

A second approach is to convert the longitude and latitude to (x, y, z) coordinates in 3d space.

I haven't used openstreetmap before, but I've just had a quick look and it appears that they use a Mercator projection.Which simply means that they've flattened the planet for you onto a rectangle, making X proportional to Longitude, and Y almost exactly proportional to Latitude.So you can go ahead and use Mac's simple formulas and you will be very accurate.

X: Y: Show position on a map. I have the Lat/Long value of an small area in Melbourne; -37.803134,145.132377 and also a flat image of that,that I exported from openstreet map( Osmarender Image ).

Earth Point Anybody can answer Its the Top left corner.Complete coordinate is (-37.803134,-37.806232,145.132377,145.136733 ) .Hey thanks for your answer . Detailed answers to any questions you might have

UTM zone numbers: Zone numbers designate 6 degree longitudinal strips extending from 80 degrees South latitude to 84 degrees North latitude. You can use the lat long converter to locate an address, latitude and longitude on a map for navigation purposely or if your gps navigation system is giving you a lat long and you need to convert it to address. 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. Coordinates Converter. If u tell me how its done or some reference link it will be easy for me to understand . Converting a table of Lat / Long values into a Shapefile - … Is it one of the corners?

Start here for a quick overview of the site More details. The valid values for the respective system can be found by moving the mouse over the input examples. Then you can figure out the pixel corresponding to a given lat/lon coordinate through To briefly outline that process, imagine that your (-37.803134, 145.132377) lat/lon corresponds to your (0, 0) pixel, and that you've discovered that your (1017, 915) pixel corresponds to the lat/lon (-37.798917, 145.138535).
Have an small doubt.According to his formula pixelY = ((targetLat - minLat) / (maxLat - minLat)) * (MAP_HEIGHT - 1) ,if I am trying to locate (-37.803134,145.132377) which is nothing but same as my top left it should be 0 isnt it ???

Convert Lat Long to UTM. Enter latitude/longitude or position. @Mac Sorry for bothering you .I just want to make it clear . UTM Universal Transverse Mercator(UTM) coordinate defines two dimensional, horizontal, positions. However, beware that many maps in Australia use the older AGD66 which can differ by 100-200 metres or so.Thanks for contributing an answer to Stack Overflow!
