  2. Hi Ujaval,

    I would like to thank you for your dedication in explaining how to use such a powerful tool.

    I do have a question for you and apologize for writing it here on this forum, but couldn't find a link where you accept questions from people.

    Is there anyway to add a small minimap of a country to a composer projection in qGis, which allows users to reference exactly where the composition is in relation to the rest of the country?



    1. Hi Enrico,

      Thank you for your kind words. I have updated this page with details on how to ask questions about the tutorials.

      For your question, you can just click 'Add new map' in QGIS composer and draw a smaller window. Then adjust the zoom level on that window by changing the 'scale' in Item Properties. So in the end you will have 2 maps with the same content in QGIS, but at different scales, allowing users to get the reference easily.

  3. Hi I am working on QGIs for the first time but I have a good experience of Arcgis. I want to overlay a twf file and NTF file on QGIS. the twf file have no contour line but the NTF file has the contour. I can't overlay both. I am thinking to get the tif format of twf file. is that right?
    Can you give me your comments or advise to overlay this two files.
    Thank you.


    1. I haven't worked worked with these formats specifically. So can't really say. You can ask the quesiton on and you will get some good advice.

      There's a plugin for using NTF files in QGIS. That maybe of help.
