- Imagery Existing (No need to wait for defoliation and weather)
- New (weather or foliage permitting)
- Ground control surveys (imagery ID points)
- Aerotriangulation for ground control densification
Your site information is compiled directly into AutoCAD using stereo pairs of
images
with
several types of stereoplotter instruments. Visible features on the images are accurately plotted in real world coordinates and placed in descriptive layers.
3D contours are at elevation and can be used in the client's engineering
design packages, Atlantis will provide your files in AutoCAD, Microstation
or any other required format .
Your project is provided in the horizontal and vertical datum as requested. Ground control is either provided by the client or
Atlantis can
be contracted to provide the control. All control is selected by a Certified Photogrammetrist to assure the quality of the complied
project.
Projects are compiled directly into
AutoCAD, Base point for the drawing is 0,0,0, for those who wish to insert it as
a block.
Deliverables are normally furnished in AutoCAD "DWG" or "DXF" format, as well as
Intergraph Microstation "DGN" format, eliminating the problems incurred with translators. The layer scheme can be in accordance with
"Client Standards" or will be according to the following

Planimetric
features to be Stereodigitized 1"=100' mapping
accuracy
| Atlantis digitizes 100%
of its topographic data directly from the original three dimensional
aerial imagery into AutoCad or Intergraph Microstation, using
specialized optical mechanical, electronic instruments, The digital
data portrays all specified features visible on the aerial imagery,
with the difference that each feature is represented by its spatial
coordinates stored in computer files, along with attributes of layer,
line type, color, etc. After digitizing, the data files are digitally
edited to provide cartographic correctness. The digital data is layered
by feature types ( roads, buildings, utilities, drainage, vegetation,
contours, etc.) The digital information can then be used to
prepare
conventional graphic line data by the use of an automatic computer aided
plotter to any scale and with any combination of layers. The scale of
the aerial imagery, and the density and the distribution of the
ground control are selected by a certified photogrammetrist to meet the
professional requirements. The advantage of
digital data, when transferred to a client's computer system, is that
this data then becomes an integral part of the project, allowing the
design team to work directly with the data as part of a GIS or CADD
project. Data searches, contract drawing, design changes and earth work
computations can be performed more cost effectively than conventional
manual design/draft procedures. Atlantis is
proud of its 100% success record of providing the digital data in the
specified formats required by the various computer systems and design
software being used by our clients. |
