GIS TRAINING Practising QGIS
Exercise 1 Using the geomorphology and GeoNames toponyms create the project below Filters Capital : "feature code" = 'PPLC Villages : "feature code" = 'PPL Mainland: "L4_ATTRIB" = 'main land'
Exercise 1 Compute the distance matrix between villages and the capital city
Exercise 1 Set the color of villages based on distance using graduated symbology and pretty breaks
Exercise 1 Create the following map and save as image
Exercise 1 Change the project coordinate system to WGS 84 / UTM zone 2S
Exercise 1 Save the filtered capital layer as a new layer with CRS = WGS 84 / UTM zone 2S Create a 20 km buffer around the capital city
Exercise 1 Clip the land within 20 km of the capital city using the buffer
Exercise 1 Delete all fields except L4_ATTRIB and add area field in Ha Save as shapefile in UTM Zone 2S
Exercise 1 Use Group Stats to calculate the total area within 20 km in Ha
Exercise 2 Add a new XYZ Tiles connection for google satellite http://www.google.cn/maps/vt?lyrs=s@189&gl=cn&x={x}&y={y}&z={z}
XYZ Tiles Google URLs Google Maps: https://mt1.google.com/vt/lyrs=r&x={x}&y={y}&z={z} Google Satellite: http://www.google.cn/maps/vt?lyrs=s@189&gl=cn&x={x}&y={y}&z={z} Google Satellite Hybrid: https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z} Google Terrain: https://mt1.google.com/vt/lyrs=t&x={x}&y={y}&z={z} Google Roads: https://mt1.google.com/vt/lyrs=h&x={x}&y={y}&z={z}
Exercise 2 Add the EEZ v10 and filter on territory1 = cook islands
Exercise 2 Download CK.zip from Geonames.org and extract CK.TXT
Exercise 2 Add the toponyms (note the CK.txt file has no field names) Set X as field 6 (longitude) and Y as field 5 (latitude)
Exercise 2 Filter the toponyms on "field_2"='Penrhyn And zoom on Penrhyn and the old air strip
Exercise 2 Add a new Waypoints shapefile of type Point with a Zone field
Exercise 2 Create waypoints around zone A and B
Exercise 2 Use Points to path to create paths by Zone
Exercise 2 Use Lines to Polygons to create polygons
Exercise 2 Read the surface area of Zone A
Exercise 3 Add the google roads to the XYZ Tiles https://mt1.google.com/vt/lyrs=h&x={x}&y={y}&z={z}
Exercise 3 Using Tonga v6 to help you locate Tonga, zoom to Vava u area
Exercise 3 Locate Ano Lagoon
Exercise 3 Create a new polygon shapefile in UTM Zone 1S Draw a polygon around the Ano Lagoon
Exercise 3 Add geometry attributes and read area and perimeter
Exercise 3 Add the centroid of the polygon
Exercise 3 Reproject the centroid layer to ESPG:4326
Exercise 3 Add longitude et latitude columns ($x and $y)
Exercise 3 Create a map
Exercise 4 Display the density of Stichopus chloronotus (sea cucumber densities) for Reef Benthos Transects in Vava u
