Mosaic is made up of numerous photographs of an area. Photos are distortion free, but not orthorectified (located in the coordinate system). Mosaics are suitable for a general overview of an area and promotion.
DOP - DIGITAL ORTHOPHOTO
Digital orthophoto of an area is a mosaic of orthorectified images, each detail having its own coordinate. Position accuracy depends on recording resolution, accuracy of metric calibration, GPS and the number of measured points on the ground.
DTM & VOLUME CALCULATIONS
By using stereo vertical images, overlapped by 50-60%, and with some additional work on the ground, we can create fairly accurate DTM - digital terrain model.
From vertical and oblique images, 3D simulation of objects or areas can be created.
LAND SURVEY PLANS
On the basis of accurate and precise digital orthophoto, Land Survey Plans in different scales with required accuracy can be produced.
