Instructions from here on assume you've got GDAL installed.įirst off you need to be sure the coordinates really are embedded in the tif. GDAL () will do almost everything you need to prep your geotifs for iOS, it's what I'm using to do exactly that. If MapTiler isn't doing what you need you should consider resorting to the utility behind the GUI.
tfw file with NotePad and this was all that is in there: 0.0004024840 via picking points on the image and then on the true map) realign/place these images? tfw automatically? - since these might hold the correct coords. Google Earth before I send it through MapTiler to cut up and process. With this said, I believe I have to manually realign these images on e.g. I simply ran this map through MapTiler on all default settings to see that it was not near-perfectly aligned over the normal Google Maps' map. (I did not create the images, but believe they might be accurate since its from the Government's Geo-Department)
tfw file with them (same name, different extension) - which I have no idea what this is. I have no clue as to what each one is/does. Specify the id-number from the EPSG/ESRI database.Universal Transverse Mercator - UTM (projected).WGS84 - Latitude and longitude (geodetic).Custom definition of the system (WKT, Proj.MapTiler is the application which I plan on using to cut these massive images up into the tiles, but it askes me for several details. My problem lies with cutting the maps up into tiles (accurately). I am trying to take these images (about 20 images) and use them as an map overlay in my iPhone app. These are in Tiff format and have coordinates embedded into them. I have images covering the whole of South Africa.
