The
data formats supported by K2Vi are described below.
GIS
- SDE:
K2Vi
can directly read and write GIS data stored in the
Spatial Database Engine (ArcSDE). This includes 2D
and 3D points, polylines and polygons. Point and polylines
features are automatically converted to polygons in
the K2Vi scene. An attribute value can be used to extrude
the GIS objects.
GIS
- Shapefiles:
K2Vi can directly read
and write to ESRI shapefiles including 3D shapefiles.
An attribute value can be used to extrude the GIS objects.
CAD and texture information is stored in dBase files
which are linked to the shape file.
GIS
- MapInfo files:
K2Vi can directly read MapInfo files.
An attribute value can be used to extrude the GIS objects.
CAD information is stored in dBase files
which are linked to the MapInfo file.
GIS
- Raster Geospatial Data
K2Vi can directly read
the following raster geospatial data formats:
- Arc/Info
ASCII Grid: This format is
the ASCII interchange format for Arc/Info Grid,
and
takes the form of an ASCII file, plus sometimes an associated
.prj file.
- Arc/Info
Binary Grid: This
format is the internal binary format for Arc/Info
Grid, and takes the form of a coverage level
directory in an Arc/Info database. To open the
coverage select the coverage directory, or an
.adf file (such as hdr.adf) from within it.
- DTED
- Military Elevation Data: K2Vi
supports DTED Levels 0, and 1 elevation data.
- XYZ
ASCII files (comma delimited): This is for example the
format that is created when exporting terrains from Socet Set.
- USGS
SDTS formatted DEMs
-
GeoTIFF: GeoTIFF
represents an effort by over 160 different remote sensing, GIS,
cartographic, and surveying related companies and organizations to
establish a TIFF based interchange format for georeferenced raster
imagery.
K2Vi
automatically creates a TIN (Triangulated Irregular
Network layer) from the loaded raster data for optimized
rendering speed. Next the user can drape image files
on the TIN and save the image with the raster data.
See our 'How to' manual for details on how to load
in raster geospatial data sets and how to drape (georeferenced)
images on the created TIN.
GIS
- Local Data:
Local
K2Vi files. This is an open ASCII file format similar
to the Arc/Info generate format.
3D
CAD - Model Data:
K2Vi
imports 3D models in the following file formats:
- 3DS
(3D Studio)
- FLT
(OpenFlight)
- BFF
(Sense8)
- VRML97
- NFF
(Sense8)
- OBJ
(Wavefront)
Imagery
-(Image Data):
Images
can be imported for use as textures on individual
polygons or on a group of polygons, for example a
terrain model (with full control of placement, orientation,
spacing etc).
The
following image formats are currently supported:
- JPG
(K2Vi supports georeferenced JPG images): A
*.jgw file containing the geo-information must
be present in the same directory as the loaded
jpg image.
- TIFF
(K2Vi supports georeferenced TIFF images): A
*.tfw file containing the geo-information must
be present in the same directory as the loaded
jpg image.
- TGA
- AVI
- PNG
- BMP
Sound
Data:
Sound can be attached to objects for added realism
or for studying the effects of objects that produce
sound. K2VI imports the following sound format:
Export
data:
K2Vi can export the textured 3D scene objects to the following formats:
- ESRI 3D Shapefile
- GeoTIFF (terrain only)
- WTK NFF format
- The
popular VRML format for distribution on the
web.
- Local
K2Vi file format.
