PRESENTATION OF THE RESULTS OF VLS TECHNOLOGY Based on this - PDF document

PRESENTATION OF THE RESULTS OF VLS TECHNOLOGY Based on this technology we can produce precise, high-resolution orthophoto (DOF 1cm), accurate 3D point cloud and of course the associated digital surface or terrain models (DSM/DTM). The results are useful for flood studies, monitoring of landslides, reconstruction and planning of infrastructure (roads, water supply, sewerage, etc.). On the other side we can produce geodetic plans for a variety of needs. By adding special sensors we could intervene in the field of agronomy by monitoring vegetation stress (NDVI - Vegetation Index) and consequently soil fertility of certain area and adjustment needs for the fertilization. 1. 3D point cloud: We provide georeferenced point cloud with realistic colours and shadows, which enables significantly easier interpretation. With special measuring tools we can measure distances in both 2D and 3D, or measure slope or height difference between two points in point cloud. 2. Digitalni surface model (DSM IN DTM): A watertight surface model that contains elevations of terrain in addition to vegetation and cultural features such as buildings and roads. Even more we provide an accurate and detailed surface representation in various grid sizes. With an automatic classification function we can easily classify point that are a part of terrain in order to calculate a digital terrain model GEOCES, nepremi č ninski inženiring Bogdan Jan č i č s.p., Trdinova ulica 1 8250 Brežice Stran 1 od 7

3. Orthophoto (DOF): F): Accurate and precise orthopho photo (DOF 1cm) is generated based on a DTM a TM and aerial imagery. It can be used to extract inform formation on positions and dimensions of roa roads, fascilities, traffic signalization, utility lines and m d musc more. On the other hand our high qualit uality orthophoto can be imported in various GIS solution utions such as PISO, TERRAGIS, iOBČINA, etc. GEOCES, nepremi č ninski inžen eniring Bogdan Jan č i č s.p., Trdinova ulic ica 1 8250 Brežice Stran 2 od 7

4. Volume calculation: Simple and elegant calculation of various different volumes, such as excavated or piled-up material. Just select the area of interest on DSM and we can calculate volumes in a mater of seconds. The calculations can beased on a single surface or compare the difference between two or more consecutive measurments. 5. Conutour lines: We can select any conutour interval to calculate conutour lines and export them to SHP, DXF format for futher use with CAD or GIS or PDF format for printing and topographic map production.

6. Profil linea and cross-sections: For every project we can create vertical cross-sections from point cloud data for any area of interest (landscapes, roads, buildings, ets.). With a few mouse click we can calculate a single vertical cross-section or multiple transverse profiles with user-defined intervals. 7. Flood studies: Without further research we can easily simulate rising water in a given area. This gives useful information which parts would be at the expected rise under water and which not (assessment of potential damage, flood protection measures).

8. Visualizations: Our data are the basis for making visualizations of planned new construction and thereby easier and more precise presentations to investors. 9. Surveying plan: With our high resolution and precise orthophoto we can get much more detailed informations about given area compared to conventional methods. What is more we can totally avoid repetition of the measurements, because we have already captured much wider zone the first time.

10. Elevation maps: One of the results of processing are so called elevation maps of the area. GEOCES, nepremi č ninski inženiring Bogdan Jan č i č s.p., Trdinova ulica 1 8250 Brežice Stran 7 od 7
