+# Basic GIS Operations
+
+The third module addresses operations and data manipulation that GIS practitioners will undertake 
+frequently. The first chapter teaches the process of digitisation, which is the process of creating 
+geodata, either from existing images, or maps, or from your own knowledge. After data collection, 
+digitisation let's you prepare the collected data for spatial analysis in QGIS. It is also useful to 
+communicate the spatial distribution of phenomenons or to simply show the collected data on a map. Next, 
+the second chapter focuses on the classification of geodata. Spatial data can have a lot of information 
+stored in the attribute table and the classification of geodata puts this information into distinct 
+classes. Through this classification, we can gain new insights and it let's us visualise geographic data on 
+maps. The third chapter, covers selecting and querying geodata. For example, you can select all data 
+entries that are under a certain distance from a point, or you could simply select data based on specific 
+values and see their spatial distribution.

 ## Data
 Download all the datasets [here](), save the folder on your computer, and unzip the file. The zip folder includes:
+
 - `som_admbnda_adm2_ocha_20230308.shp`: This file contains information about the Somali administrative level 0-2, state, and operational zone level 1 and 2 boundary as shapefiles. The data can also be found on [HDX](https://data.humdata.org/dataset/cod-ab-som).
 - `GF2_20231123_FloodExtent_BeledweyneCity_HiraanRegion.shp`: This shapefile illustrates satellite-detected surface waters in Beledweyne City, Beledweyne District, Hiraan Region, Somalia, on 12th of November 2023 at 07:32 UTC. The data is also available on [HDX](https://data.humdata.org/dataset/water-extent-in-beledweyne-city-beledweyne-district-hiraan-region-somalia-12-november-2023).
 - `Buildings_Belete_Weyne.geojson`: This dataset is downloaded using [HOT Export Tool](https://export.hotosm.org/v3/exports/new/describe) and contains information about buildings in the Beledweyne district.
 
 The folder is called **Module_3_Exercise_1_Queries_Somalia** and contains the entire [standard folder structure](/content/Wiki/en_qgis_projects_folder_structure_wiki.md#standard-folder-structure) with all data in the input folder.
 
 ``` {Note}
-The naming of the districts and states is not consistent across the different datasets. You will find different spellings for the district name **Beledweyne** which we will be focusing on. Other spellings might be **Belet Weyne** or **Belete Weyne**.
