Practical work with QGIS (LOOM.02.331, A. AASA)
http://www.qgis.org/en/docs/training_manual/ http://maps.cga.harvard.edu/qgis/ Data for practical work: http://aasa.ut.ee/LOOM02331/data/data.7z
Exercise 1: Create thematic map “Distribution of Estonian population
in relation to nature preserves”.
Data layers: population_1km_grid_census2011.shp, preserves.shp Introduction to QGIS: http://mappingmashups.net/2012/11/30/a-very-short-introduction-to-qgis/ Output: map and short description.
Work steps:
Load data to QGIS (Add Vector Layer; *.shp!!)
Check the projection (for Estonian data projection is L-EST97; EPSG:3301)
Change the order of layers (topology)
Zoom full ; zoom to layer
Plugins (many analytical tools are available via plugins)
Change symbology (colours); double-click on layer name.
Output (final map) is designed in “Print Composer” Save map as jpg / pdf / …
o Add new map to composer
o Legend: ; map scale:
o Export:
Exercise 2: How many people live in the 2 km buffer zone of Tallinn –
Tartu – Luhamaa highway? Data: Tallinn_tartu_luhamaa_road.shp, population_1km_grid_census2011.shp, Output: document with a thematic map and the population size in buffer zone. Work steps:
add relevant layers to your QGIS project
Create 2 km buffer for main_roads.shp. (How to create buffers:
