Open TFW File

A TFW file is most commonly known as a World File, associated with a TIFF (Tagged Image File Format) image file. It provides georeferencing information for the image, widely used in GIS (Geographic Information System) applications. This article will cover the different formats and ways to open and use TFW files, discussing their significance in geospatial data management.

Understanding TFW Files

TFW files are plain text files that store six parameters, each line containing one parameter. These parameters include information about the size of a pixel, rotation terms, and the coordinates of the upper-left corner of the image. While there are various uses and programs that can open a TFW file, GIS applications like QGIS, ArcGIS, and Global Mapper can efficiently handle and process them, associating the TFW file with the corresponding TIFF image.

TFW file as Text World Files

As previously mentioned, a TFW file is primarily a Text World File that accompanies georeferenced raster images in GIS applications. When opening a raster image with georeferencing information in GIS software, it automatically searches for a TFW file with the same name as the image file. If found, the software uses the information in the TFW file to correctly place and scale the image. With the right software and tools, you can easily create, open, and edit TFW files. Some popular GIS applications that can handle TFW files include QGIS, ArcGIS, and Global Mapper.

Editing TFW files

Since TFW files are plain text, they can be opened and edited using any basic text editor like Notepad++, Sublime Text, or the default text editor of your operating system. Remember to keep the required format when editing these files, or you may cause issues while processing them in your GIS software.

Converting TFW Files

Usually, converting a TFW file is not necessary because the file itself only contains georeferencing information. However, if required, you could use tools to convert the accompanying TIFF image to another raster format like JPEG or PNG, then use georeferencing software to create a new World File for that specific format. GIS applications like QGIS come in handy to georeference raster images and generate new World Files.

TFW File Important Information

It is crucial to know that TFW files don't hold any geospatial data themselves. Instead, they contain essential spatial context information for their associated raster files (usually in TIFF format). When dealing with geospatial data, always ensure your TFW files and their corresponding images share the same name so that the GIS software can accurately utilize the georeferencing data.
