*2.2.2 Mapping in QGIS*

**Figures 2** and **3** and **Table 2** show the largest population cities in the western Balkans. The map was constructed with QGIS. The methodology was based on the addition of the Google Satellite background. The shape files of cities were designed. In addition, the spatial and descriptive archive of towns was created. The cities have fields in the illustrative data table, name and population.

With the editing process, the points were formed, the size was increased, and the color was modified. Finally, with help of the labeling toolbox, the field name was activated, and the names of the cities appeared on the map. The map was exported as an image in scale, representing all the cities of the western Balkans [3].

New technology for assessing the technical condition of datasets and vector sets is proposed. The core of this technology is an estimation of defects and deformations of structures using QGIS during map construction and operation [4].

The methodology is based on data management analysis and QGIS software. Firstly, the author searches the pertinent data about the population in the Balkans cities and demographic sizes. Next, the author creates diagrams with the use of excel office. The diagrams present an innovative understanding of the population, municipality area, elevation, and destiny.

Also, this data uses in QGIS. The following steps create a point layer relative to the name of the cities. This layer shows the main cities in the Balkan area and the classification is about the size of the population. Finally, the user presents the methodology of the progress in the diagram. The progress in one part of the scientific study of spatial analysis assistance of the QGIS (**Figure 4**).
