Description In the modern geological mapping activities, geomatics technologies can facilitate data collection during field survey and avoid practical problems related to the transposition of that data onto topographic maps.
Printed geological map can be produced with a GIS layout.
Portable instruments such as GPS and laser distance meters can reduce such errors, but the Solid True Orthophoto (STOP) can minimize the difficulties and sources of inaccuracy encountered during field surveys.
The STOP is a new product that integrates an orthophoto (2D photographic map) with the height values derived from the Dense Digital Surface Model (DDSM) generating georeferenced 3D information. In fact, STOP can be view using an experimental software tool, developed by the authors in Visual Fortran that includes simple query functions, a 3D coordinate viewer, some measurement commands (e.g., angles, 3D distances, areas, planes, volumes), georeferenced note and comment record utilities.
This viewer can be used on a simple netbook or tablet PC permitting the surveyor to acquire, directly on the field, the 3D geological information in a more rapid, comprehensive and accurate way. In fact, the GSTOP (GNSS STOP) viewer can manage, in real time, a direct connection with navigation sensors as a low cost GPS/GNSS receiver to define the current location and a low cost IMU sensor to measure attitude angles (heading, pitch and roll ) of PC: inside the STOP, the user can view his position (a red circle) and the azimuth of line of vision (a red arrow) and generate a 3D solid image in order to be compared the effective scene.
This thesis must develop an IPAD application of GSTOP.
