The workflow is meant for beginners starting to work with NICFI data. You can choose to follow all three of the steps, or only follow one step. After clip, you are going to use Raster Calcualtor to perform NIDVI. You will first mosaic two basemap quads and then clip the mosaic to an area of interest. This tutorial will cover basic raster operations in QGIS.

Type sudo apt-get install qt4-designer (Password: user)Now we create a custom form with QT Designer:4.2.Beginners QGIS Workflow with NICFI data Introduction Click Applications Accessories Terminal Emulator 2. This allows QGIS to run forms created with QT designer without compilation.For installing QT designer, open a terminal: 1. QGIS relies on naming conventions for dataelds and expressions. Activate the edit mode and digitize a point to see the new edit form:4.2 Forms with QT DesignerQGIS supports also custom forms, created with the QT GUI Designer.
