Now we can see all the points where we collected data!Īs we saw earlier, the data contains environmental measurements such as: salinity, turbidity, temperature and others. For GPS coordinates, as the data we are using here, you need to select WGS 84 ESPG 43126. You’ll be prompt to select the coordinate reference system selector, and this is very important because if you do not select the right one you’ll get your points in the wrong location. You can leave everything else as default and click ok. QGIS is smart enough to recognize longitude and latitude columns but double check! You can also see an overview of the data with columns for latitude, longitude, Barometer mmHg, conductivity, Salinity psu and other variables. Additionally, make sure that X field represents the column for your longitude points and Y field for latitude. Make sure that csv is selected for File format. You’ll browse to the file with your data. Or you can click on Layer-> Add Layer-> Add Delimited Text Layer. To input data you’ll go to the icons on the far left and click on “Add Delimited Text Layer”. You can do this with your own data by creating a file in excel and have a column with longitude and latitude values and columns with other variables and save it as a csv file. We will now add our data file which contains latitude and longitude of all the sites we collected samples, in addition to values for salinity, temperature, and turbidity. It is important to know what kind of data you are importing to QGIS to use the correct function. At the far left you’ll see a list of icons that are used to import your layers. Layers can be raster data or vector data, in this case we see the layer: ESRI Satellite. You’ll also notice that on the left side you have a Layers panel box, this box shows all the layers you add to your map. You can click on the zoom in icon to adjust the zoom, as shown in the map below where I zoom in the Galapagos Islands. Go to–> Web->QuickMapServices–> Esri–> ESRI Satellite I recommend playing with the various options in either OpenLayers like the Google satellite, physical, and other maps layers, or QuickMap Service.įor this map, we will use ESRI library from QuickMap services. This will generate more options for mapping. To install it you should follow the same steps as you did for the OpenLayers plugin except this time you’ll type QuickMap Service and install the plugin.Īlso, If you want to experiment with QuickMap services you can expand the plugin: Go to Web->Quick Map Services->Settings->More services and click on get contributed pack. This is a very useful plugin which offers more options for base maps and less zoom errors. There is another plug in: Quick Map Service which uses tile servers and not the direct api for getting Google layers and others. However, the OpenLayers plugin could generate zoom errors in your maps. This plugin will give you access to Google Maps, openStreet map layers and others, and it is very useful to make quick maps from Google satellite, physical, and street layers. This will open the plugins dialogue box and type OpenLayers Plugin and click on Install plugin. Go to Plugins and select Manage and Install plugins. II.Install QGIS Plug-in and Upload a base map. You should follow the instructions and install gdal complete.pkg, numpy.pkg, matplotlib.pkg, and qgis.pkg. QGIS is a very powerful tool and user friendly open source geographical system that runs on linux, unix, mac, and windows. Learn how to select attributes from the data e.g., salinity values and plot them. Learn how to import vector data: import latitude, longitude data and additional data. Learn how to upload raster data using the Plugin OpenLayers and QuickMap services. Hi! I’m Natalia Erazo, currently working on the Ecuador project aimed at examining biogeochemical processes in mangrove forest. In this tutorial, we’ll learn the basics of (free) QGIS, how to import vector data, and make a map using data obtained from our recent field trip to the Ecological Reserve Cayapas Mataje in Ecuador! We’ll also learn standard map elements and QGIS function: Print Composer to generate a map.
