# Continue outlining the island by clicking along its shoreline. When you are on your last point, instead of left-clicking, right-click. QGIS will finish the polygon. | # Continue outlining the island by clicking along its shoreline. When you are on your last point, instead of left-clicking, right-click.

# A dialog box will pop up, asking you to type in the value for 'class'. Since this is a shoal, existing of just sand, type in ''Sand''. This step is important - it is how you know what each polygon should be mapped to in our finished scenery. A list of "allowed" materials (and thus classes) is available [http://wiki.osgeo.org/wiki/LandcoverDB_CS_Detail here]. | # A dialog box will pop up, asking you to type in the value for 'class'.

We have been working with UTM coordinates so far. To generate scenery that can be used in FlightGear we need to convert the shapefiles to the latitude/longitude format. | |||
* '''Windows''' | |||
*# Download [http://www.forestpal.com/fgis.html fGIS] and install it as described. | |||
*# Open an empty project and visit <tt>Utilities > Shapefile Projection Utility</tt>. | |||
*# Look up your projects UTM coordinate through [http://upload.wikimedia.org/wikipedia/commons/e/ed/Utm-zones.jpg this image]. For Texel this is 31U, so we choose UTM31 in fGIS. If your project is located south of the equator, you tick the S box. | |||
*# Set the Output Shapefile Project to <tt>Lat./Lon.</tt>. | |||
*# Now click the Input Shapefile button to load the shapefile that we exported from qGIS. | |||
*# Using the Output Shapefile button we decide where we want to store the lat/lon shapefile. This has to be a non-exisiting file, so remove before updating. | |||
*# Click the Convert button. | |||
