Professional authorial engagement supports many requirements  of hydrologists and geologists in the fields of hydro/geotechnical engineering.  

​

With regard to that, there can be offered many services, listed below:

​

     - Highly professional “On-Image-Geometry” Perspective Restitution of existing (morphologically simple/complex) hydro/geological structures of any           size – presented on analog/digital photographs or video-images,

​

     - Highly professional “On-Image-Dimension” Perspective Restitution of existing (morphologically simple/complex) hydro/geological structures of               any size – presented on analog/digital photographs or video-images,

​

     - Accurate Rectification of single or multiple photo-sets (making ortho-images without perspective distortions –e.g. elevation drawings/profiles of               existing hydro/geological structures - to make/broaden relevant hydro/geotechnical documentation for archival/scientific/educational/constructional         purposes),

​

     - All relevant accurate Non-contact (On-image) Linear, Surface and Volumetric Measurements of existing (morphologically simple/complex)                       hydro/geological structures - based on usage of their previously restituted characteristics (e.g. to perform various hydro/geotechnical calculations           and analyses - i.e. erosion/subsidence-monitoring, water-flow monitoring etc.), 

​

     - Highly realistic 3D-Modeling existing (morphologically simple/complex) hydro/geological structures of any size – based on usage of their                         previously restituted data sets, (e.g. modeling of earth surfaces/ground-reliefs, water-flows, open pit mine faces, slag heaps, cliffs and exposed                rock faces, tailing piles, etc.), 

​

     - Previously generated 3D-Model Editing (Reverse Engineering), by redefining geometry of their curves (edges) and surfaces as NURBS-ones                 (e.g. to make/broaden project documentation related to planned hydro/geotechnical interventions),

​

     - Previously generated 3D-Model Animation (e.g. in the form of superior virtual tours/”walk-through dynamic presentations” for                                           scientific/educational/promotional/ purposes, etc.), and

​

     - Preparing generated 3D-Models for export to relevant computer programs. 

​

​

                                                                                                                    -ooo-

​

NOTE THAT DESCRIBED PROFESSIONAL ENGAGEMENT IS ESSENTIALLY IMPORTANT  - ESPECIALLY IN THE FIELDS OF “NON-CONTACT” MEASURING AND PHOTO-REALISTIC 3D-MODELING OF EXISTING GEOLOGICAL STRUCTURES WHEN: THEIR RELEVANT DOCUMENTATION DOES NOT EXIST OR WHEN THEIR LOCATIONS ARE HARDLY ACCESSIBLE/COMPLETELY INACCESSIBLE OR ACCESS 
IS VERY RISKY.
