Convert X Y Pixels to Easting Northing Right I've got a bit further but my Northing calculation is wrong: If I take Edinbourgh for example on the MiniScale image the x,y would be 3270, 6264. I'm then using the Worldfile data of: A: 100 B: 0 C: 0 D: -100 E: 50 F: 1299950 X = A * 3270 which is Edinburgh on the miniscale + B * 6264 which is Edinburgh on the miniscale + C This gives me X 327000 which seems correct I then do this calculation for Y: Y = D* 3270 which is Edinburgh on the miniscale + B * 6264 which is Edinburgh on the miniscale + F This givesme Y 1286150 which is not correct. Any ideas? |

Convert X Y Pixels to Easting Northing Thanks for your advice. I'm just using the free data provided by Ordnance Survey OpenData. At the moment i'm looking at the MiniScale tif file, I'm wanting to take the Easting and Northing data I've been given and plot this out on a the tif. I know its not quite as simple as just taking the easting and northing and converting this into the pixels of the image. As to start with the top left of the image would be 0,0 yet the grid would be 7000,13000. So i'm looking for a guide or formula that would convert the easting / northing to the pixel of the image. |

Convert X Y Pixels to Easting Northing Hello, Thanks for getting back to me. Taking the Ordinance Survey Mini Scale tif for example this image is 7000 x 13000. Edinburgh is Easting 324995 (X) and Northing (Y) 674112. Now is I was to move the mouse over the x y of the image Edinburgh would be 3254, 6266. How do I get this x y pixel to compare the the 6 digit easting northing? |
