Using QGIS is essential in starting a project as it will concentrate all spatial data needed for displaying or exporting in other softwares such as Kingdom or Petrel.<\/p>\n\n\n\n

First, you must download the latest stable version here:<\/p>\n\n\n\n

https:\/\/www.qgis.org\/en\/site\/index.html<\/a><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

QGIS has a very active community, meaning that if you have a question, probably someone had the same question long before you and got the answer:<\/p>\n\n\n\n

https:\/\/docs.qgis.org\/3.28\/en\/docs\/training_manual\/index.html<\/a><\/p>\n\n\n\n

In the following lines, I will explain how to import a map and get georeferenced points. That’s a good start !<\/p>\n\n\n\n

Open QGIS, click on the project menu on top of the window and click new then save as and choose a name and a location on your computer, then click again on properties.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I suggest you choose first WGS84 as it covers all earth. Then we can pick a projected system<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In this example, we will import a geological map on which georeferenced points are known. Any image\/picture is considered as a raster file.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

So, we need now to import it in QGIS.  You can click  layer ->Georeferencer<\/p>\n\n\n\n

In the window that opens, click on <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

to import the image. Select the image and click add.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Click on add point <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

and start picking points using the graticules (square lines on the map). Enter X (East) and Y (North) corresponding to the crossing line points and click Ok. Do it for every points on the map.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once done, click on start georeferencing<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

and choose parameters in the window that pops up :<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

You can set the target CRS to EPSG 32632 meaning that you are in WGS 84 UTM zone 32. If it doesn’t work uncheck the “set target resolution”.<\/p>\n\n\n\n

You can close the geireferencer window.<\/p>\n\n\n\n

Now your project should look like this:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Now we will add a Web Map Service.<\/p>\n\n\n\n

By default GEBCO data are designed for regional projects. Click on Layer -> Add Layer -> Add WMS\/WMTS Layer<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Select GEBCO, click connect and select the GEBCO Grid-Shaded relief, then click add. If GEBCo is not set in your QGIS version, please visit this site: https:\/\/www.gebco.net\/data_and_products\/gebco_web_services\/web_map_service\/<\/p>\n\n\n\n

the WMS service is: https:\/\/wms.gebco.net\/mapserv?<\/p>\n\n\n\n

So, click new and add this line<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It will add the shaded relief map as displayed below:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Just be sure that the GEBCO data is below the geological map in the left pane. If not, just drag and drop it below.<\/p>\n\n\n\n

 Now we will add the administrative boundary as a shapefile. A lot of shapefiles are available on internet. <\/p>\n\n\n\n

For Nigeria, one is available here: https:\/\/datacatalog.worldbank.org\/search\/dataset\/0039368<\/p>\n\n\n\n

simply download it and unzip in the dedicated QGIS folder.<\/p>\n\n\n\n

Now click on Layer -> Add Layer -> Add vector layer (shapefiles are vectorized lines or points)<\/p>\n\n\n\n

Select the file with the .shp extension and click add<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Right click on the newly shapefile in the left pane and click on properties or simply doucble click on it<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In Symbology, you can set the transparency and color.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If you wish to add openstreet maps, that’s simple: just click on XYZ tiles in the left pane, and click on OpenStreetMap. It’s done !<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

ENJOY !<\/p>\n","protected":false},"excerpt":{"rendered":"
