−	~~=== Exercise Data ===~~
−
−	~~'''Type of Data'''~~
−	Four simple datasets are used for these examples including 3 vector and at least one raster data file. Each file should generally overlap the region of the other files so that comparison operations can be done in the exercises:
−	~~# points - several dozen points roughly grouped together~~
−	~~# lines - a simple network of lines would be ideal~~
−	~~# areas - one or more polygons~~
−	~~# raster - with some simple grouped classes, not too noisy and similar in appearance to points, lines or areas.~~
−
−
−	~~'''Specific Examples'''~~
−	~~All examples in this instance of the training are from the North Carolina demonstration dataset shapefiles and grids.~~
−	~~# points - bus stop locations - ''busstopsall.shp''~~
−	~~# lines - stream network - ''streams.shp''~~
−	~~# areas - lakes - ''lakes.shp''~~
−	~~# raster:~~
−	~~## a single point-like feature class - ''facility.grd''~~
−	~~## road linework - ''roadsmajor.grd''~~
−
−	~~=== Buffering a Multiple Point Shapefile ===~~
−
−	~~==== Method ====~~
−	~~# open GIS application~~
−	~~# add shapefile or raster layer to the map view~~
−	~~# zoom to the extent of the layer~~
−	~~# select ''buffer'' geoprocessing tool~~
−	~~# enter required parameters and options:~~
−	~~## ''input layer'' - the layer that the buffer operation will be applied to~~
−	~~## ''output layer'' - the new file that will be created and include the buffer features.~~
−	~~## ''distance'' - the distance from the input features that the buffer will be created at~~
−	~~## options - including the option to ''dissolve'' the resulting features by merging the buffer features together instead of retaining the individual buffer lines of overlapping buffer perimeters.~~
−
−	~~==== Exercise using QGIS ====~~
−	~~This exercise uses the above method as it applies directly in QGIS. Other projects will be welcome to add their own example exercises as well.~~
−
−	~~'''TODO: Add screenshots'''~~
−
−	~~# Launch QGIS~~
−	~~# Load the data layer. Using menus at top of screen select '''LAYER -> Add Vector Layer'''~~
−	~~## Press '''Browse''' button~~
−	~~## Navigate to the folder holding the sample datasets and select '''busstopsall.shp''' and press '''Open''' button~~
−	~~## QGIS will automatically zoom to the extent of the bus stop features~~
−	~~# Run the buffer process from the menu: '''TOOLS -> Geoprocessing Tools -> Buffer(s)'''~~
−	~~## Set the '''Input vector layer''' to '''busstopsall'''~~
−	~~## Enter '''Buffer distance''' of '''200'''. This will be 200 metres.~~
−	## Set the '''Output shapefile''' by pressing '''Browse''' button. Navigate to the data folder and enter the new filename as '''busstops_200m_buffer.shp'''. Press '''Save''' button to select that filename.
−	~~## Press '''OK''' button to run the process.~~
−	~~# After running, the system asks '''Would you like to add the new layer to the TOC?''' select '''Yes''' and the resulting shapefile will be added as a layer in your map view.~~
−	~~# Buffer(s) window remains open. Press '''Close''' to close the window.~~
−	~~# Reorder the layers so the resulting buffer polygons layer is on the bottom of the layer stack. Click and drag the ''busstops_200m_buffer.shp'' layer to beneath ''busstopsall''.~~
