The basic activity, therefore, was texturing of the terrain surface created earlier. The texturing process is used to give the 3D surface a texture, i.e., a digital image, most often representing the type of material from which the modeled object is made. The process of applying a texture, a map, a satellite image, or an aerial image to a digital terrain model is called draping. The results of the draping of the DTM model, using digital rasters saved in GeoTiff format, are presented in Figures 19-22. To display high resolution textures, the Rendering option set in the Phong display mode was used with the anti-aliasing shading method. Enabling anti-aliasing smoothes the edges of the displayed texture model, making the scene (or render) look more natural. The texture of the topographic map was insufficient for creating a good-looking digital terrain model. In order to give the relief model a similar look to the natural terrain surface, it was necessary to reach for the implementation of aerial photographs. As a result, we decided to create a mosaic of rectified aerial photographs available on the Geoportal website. The calibration was made by similarity, taking into account situational details on the map, such as buildings, roads, and borders of land (Figure 23). After completing the aerial photograph adjustment, the mosaic fragments were merged into one common file and saved in the GeoT

In this way, a basic texture was developed for the terrain model, which is the \"background\" of the DSM being built. Then, the renders (Figures 25 and 26) of the surface of the digital terrain surface model (DSM) were presented with a basic texture, which is a mosaic of the aerial photographs. This surface has been extended in the next stage of research, with elements of land cover. The digital terrain surface model illustrates the connection of field elements with the terrain relief. DSMs depict the location, shape, and height of natural objects, such as trees, and artificial ones, such as houses, economic facilities, technical infrastructure, and others. The digital terrain surface model contains a number of applications used in various engineering, planning, and similar branches. For the purpose of the research, several groups of land cover details were adapted, and, next, they were implemented in the DTM model covered with a basic texture. These were: building blocks, trees, and elements of technical and engineering infrastructure. The creation of the DTM of the Kamionka Wielka object was carried out using LIDAR data. The

In addition to the previously classified classes, it was necessary to determine the model key points, i.e., points that show the relief of the area; based on them, it is possible to generate the digital terrain model (Figure 27). The final effect in the form of the DTM of Kamionka Wielka is shown in Figure 28.

The model depicts roads, the Raba river, and its tributary Kasinianka. A separate layer representing forest areas, given a dark green color, was also created.
