1/12/2024 0 Comments Maptiler wrong![]() PosY - the Y position of the corner (again, mostly coordinate of the top-left one) RotX - rotation of the X line (in case of unrotated images, this value should be 0) ScaleX - resolution of the X line (in most of the cases this is the West-East pixel resolution) PosX - the X position of the corner (mostly coordinate of the top-left one) The format for geotransformation is “posX scaleX rotX posY rotY scaleY” with spaces between numbers. Geotransformation defines the position of an image by one corner position, the scale of the image, and its rotation. Assigning a position via bounding box is illustrated in the following tutorial: Corners' coordinates can be easily set by Bounding Box Tool. ![]() Default value -180 -90 180 90 covers the whole world. The Bounding Box has to be specified in this order: West, South, East, North. In the situations where coordinates of the map corners are known, you can use Specify Bounding Box option that creates a border of the map itself. If you have such a file, just click on the import button, choose the file, confirm, and the Georeference will be loaded. gfw, or exported from GIS software such as OziExplorer or MapInfo (extensions. If you are working with previously processed files, some of them have already position saved in the external files. The whole process is in detail described in this tutorial, common usage can be seen in this video: The best choice is to pick points on different parts of the map and do it as accurately as possible: this can be accomplished by choosing corners of buildings, crossroads, peaks, and other clearly identifiable points. The minimum is three points, but the accuracy increases by selecting more. All you need to do is select a few points on the already published map as well as on your image. This is the most common situation for scanned maps, photos from your drone, or other materials captured by you. If it is not known, you have a few other options on how to georeference your image: ![]() In the best-case scenario, the geographical position system was already set previously by external software and MapTiler Engine automatically loads it. This action turns your picture into a map. By this, you define where exactly your picture is located on the planet. When the coordinate system is specified for your picture, you can set the geographical position. This article describes the process of setting the geolocation for your image and transforming it into a map. ![]()
