Orthophoto is an orthographic projection of a portion of territory, more precisely a geometrically correct image from above. It allows measuring distances and areas in planimetry, useful for spatial planning, architectural planning, environmental monitoring, updates to existing cartography and much more.
The digital terrain models are graphic products that represent the elevation of the detected terrain or of the anthropic and natural elements present on it. We provide the raster data used for different spatial analysis elaborations, especially in GIS environments. Elevation models are used for slope studies, volumetric studies, support analysis for urban and territorial planning and much more.
Contour lines are isolines representing an imaginary line on the land surface where all points are at the same elevation above a given plane. These are generated by digital terrain models. Contour lines are a useful tool for territory analysis as they provide information about terrain and slope trends. Data provided to customers can be easily imported in CAD and GIS.
The point cloud is a set of points that we generate from the photo matching process. At each point of the cloud is associated its own position in a coordinate system and a value that characterises its colour. We use point cloud to represent a three-dimensional structure and as a basis for creating 2D and 3D graphics products, such as digital models and polygon meshes.
Using the point clouds generated from the acquired photos, we are able to produce photorealistic 3D models and polygonal meshes perfectly scaled. Therefore, the generated models report characteristics of shape, size and colour which correspond to reality.
Aspect map provides a coloured representation of exposure. The orientation of the downward sloping terrain is indicated by different colours representing: North, East, South and West. This service can be used to environmental analyses, agricultural sector and for example plan the orientation of PV panels.
Slope map provides a coloured representation of slope, generated dynamically using a server-side slope function on the DTM. The degree of slope is represented by a colormap that identifies: flat surfaces, moderate slopes and steep slopes classified by degrees. This service can be used as alternative visualisation of slopes instead of contour lines.
We use drone photogrammetry technics to obtain three-dimensional models of the objects such as land or buildings. Leveraging on drones, we can overcome the limits of the surveys carried out by airplanes and helicopters, both on the operational and economic side. We are able to supply very detailed and affordable products whilst operating in complex environments difficult to access. We are able to process and produce 2D and 3D digital models that reproduce geometrically correct and georeferenced characteristics of the shape, size and colour of the detected objects. Our models can be easily imported in CAD and GIS environment for designing and creating databases.
