2.1.1 New Project

New Project Widget

Fig. 2.1 New Project Widget

Widget to create new LSAT projects.

2.1.1.1 Usage

  1. Specify the project location by picking a folder (1)

  2. Name the project (2)

  3. (Optional) Provide a description (3)

  4. Provide spatial reference (2 Options):
    1. Use a mask raster (4).
      Specify a mask raster dataset (6). This will attempt to auto fill EPSG code (7), Extent
      (9) and cellsize (10)
    2. Use a custom extent (5)
      Fill EPSG code (6), Extent (9) and cellsize (10) by hand. Open the
      Coordinate System Widget (8) to help with the EPSG Code.
  5. Create a new project (11) (If you provided a mask you may
    import it into the new project)

To achieve the best results in later analyses use a mask raster dataset.

LSAT PM only supports mask raster datasets with square cells.

You can later change the project description with the Project Info Widget

Some raster datasets use underscores instead of spaces in the name of the coordinate system. If that is the case you can still use it as a mask but will have to provide the EPSG Code (7) by hand (8) using the Coordinate System Widget.

2.1.1.2 Coordinate System Widget

Coordinate System Widget

Fig. 2.2 Coordinate System Widget

With the coordinate system widget you can alter the EPSG code the project uses.

Usage

  1. Use the combo box (1) to choose either projected or geographic coordinate systems.

  2. Select the coordinate system (2 Options):

    1. Type the EPSG Code into (4) and press Enter.

    2. Type the name of the coordinate system into (2) and press Enter or click (3) and then click
      on the coordinate system in (5).

  3. Click (7) to use the selected coordinate system.

Clicking on Details (6) will open epsg.io with information about the coordinate system. If there is no EPSG Code (4) it will open epsg.io itself.

2.1.1.3 Mask raster dataset import

Mask import dialog

Usage

  1. Choose to import the mask (1) or don’t (2).

If you import the mask raster dataset the raster import dialog opens, guiding you through the process.
