For most GIS persons, exporting the map to a georeferenced image is an important task. When we export a map to a georeferenced image, we can then open the image in other GIS software. And, we don’t have to rectify the image again because it has the geographical information already. In this article, we are going to learn how to export map to a georeferenced image in QGIS.
The export to image feature in QGIS is very helpful. We can export the whole map, layer extent or we can also draw the area to export.
What do we need?
- QGIS software in your system
- A map
- A little efforts
Steps to export map to a georeferenced image in QGIS
First, open the map to the QGIS canvas. If you start with a blank canvas, then you will need to add some layers to your canvas.
Next, go to File >> Import/Export >> Export Map to Image
On the configuration window, you can specify some important stuff. You may use the map canvas extent, draw on the canvas and calculate from a layer. This option will specify the actual extent of the map you are going to export.
Next, you can also specify the scale for the exported image, set the resolution. Higher dpi means better quality but it will end up with bigger file size. Click the Save button when ready and then choose where to save the file. There are many image formats supported by QGIS. For example, you can choose JPEG, GeoTiff or some others.
That’s it. Thank you for reading this article, I hope you enjoy it and see you.
