 | Image Formats: TIFF, GeoTIFF, JPEG, GIF, RLC, PNG and BMP
formats. R2V supports most image types, including 1-bit bi-level,
8-bit grayscale, and color images (4-bit, 8-bit, and 24-bit). Most
TIFF image compressions are supported. There is no software limit
for image sizes. R2V also supports SPOT and other satellite raw
image formats. Geo-reference your raster image in R2V and save to
GeoTIFF format. |
| Vector Export/Import: ArcView (Shape file), Arc/Info
Generate, AutoCAD DXF, MapInfo (MIF/MID), IGES, MapGuide SDL, 3D
Grid file, 3D DEM (compatible with USGS DEM), VRML, and 3D XYZ
vector file formats. |
| Advanced Vectorization: R2V supports three types of
vectorization:
- Fully automatic vectorization. One command will vectorize
your scanned map in seconds or minutes at high quality. Batch
function allows vectorizing a number of maps without any user
intervention. Write your own batch script to customize the
processing steps for the images before vectorization and for
vector line processing after the vectorization.
- Interactive line tracing. You select two points on the image
and let R2V trace the line for you. Easy, accurate and
intelligent! For complex maps or drawings, use the interactive
tracing to vectorize lines selectively. Or use the multiple line
tracing function to vectorize a group of lines with only two
clicks.
- Manual on-screen heads-up digitizing. With R2V's easy to use
vector editor, you simply draw the lines with your image as the
backdrop, zoom in and out, and quickly create the data set for
your specific applications.
|
| Complete Vector Editing: A complete on-screen vector
editor is provided using the image as a backdrop. Lines can be
created, moved, joined, split, removed, colored, and labeled. Closed
polygons are formed easily from existing lines with the polygon
editing tool. |
| Vector Labeling and Contour Map Digitizing: Lines can be
labeled with different ID values which are saved as attributes when
exporting to a mapping or GIS package. Semi-automatic contour line
labeling is supported for quick elevation assignments of contour
lines. |
| Vector Rasterizing: Converts vector data to high
resolution raster image for printing and processing. |
| Multiple Layers: Use R2V's layer manager to define as
many layers as needed to organize vectorized data into layers.
Layers created in R2V are fully compatible with the export vector
file formats that support multi-layer structure. With multiple
layers defined, vector data can be processed, edited, and displayed
by layer and moved between layers. Layers can be turned on, off, or
locked for flexible vector data editing and handling. |
| Point Feature Digitizing: Complete support for digitizing
of point features. Points can be created, moved and labeled. Point
data can be exported to all the vector file formats supported. |
| Automatic Polygon Layer Creation: Create polygon layers
automatically from vectorized lines with just one command. The
closed polygons can then be edited, and labeled using R2V's line
editor. Polygons can be displayed in fill mode with a user defined
hatch pattern and color for the layer. |
| Powerful Raster Image Editing: R2V provides a powerful
raster drawing tool for easy image pixel editing and repairing. All
image types, including 1-bit monochrome, grayscale, 8-bit color, and
24-bit color are supported by the Image Pixel Tool. Pixel
mapping functions can easily map one pixel value to another for the
entire image to remove noise pixels, clean up image background, or
merge color layers. |
| Geo-Referencing Using GeoTIFF or Control Points: Vector
data can be geo-coded or geo-referenced to a real world coordinate
system (e.g., UTM, Latitude/Longitude) using GeoTIFF, user selected
control points or a World file (TFW). Raster images can be
geo-referenced as well with a generated World file supported by
ESRI's Arc/Info, ArcView, or TAB file by MapInfo. Image rubber
sheeting functions allow geometric correction or registration of an
image to a new coordinate system. R2V supports both Bi-linear and
Delaunay triangulation methods for geometric transformation.
Geo-referenced raster images can be saved in GeoTIFF format, and are
fully compatible with other packages that support GeoTIFF. |
| Conversion between Map Projection Systems: R2V supports
conversion between UTM coordinate systems, latitude/longitude, State
Plane NAD27 and State Plane NAD83 systems. You can convert one point
or an entire set of control points automatically. |
| Automatic Text Detection and Recognition (OCR): Detects
and recognizes text of any font, any size, and any language
automatically. Flexible editor for easy removal and manipulation.
Other irregular intersection symbols can be detected and corrected
as well. |
| Merge Multiple Maps: Use R2V to vectorize maps separately
and then merge them into one set by specifying proper control
points. The merged vector data set can then be edited within R2V and
treated as a single map. |
| Flexible Region of Interest for Vectorization and Image
Processing: R2V supports regions of interest in the form of
circles, rectangles, free form polygons, and their combinations for
vectorization and image cropping.
 |
| Powerful Image Processing: Vertical and horizontal flip,
transpose, rotate, remove dark background, edge detection, image
resample, crop a region, smoothing, segmentation, image mosaic,
fusion, warping, and negate. Both supervised and unsupervised
classification are built in to help process aerial photos or
satellite imagery that are in color. Color separation, grayscale
image enhancement, and image type conversions can all be done using
R2V. |
|
 |
| Image Mosaic: R2V's Image mosaic command makes
it easy to create a mosaic image from a series of sub-sections.
Simply start by selecting the Image/Mosaic option, and
specify the layout matrix and image file names. The image mosaic
will be created in a few seconds. Images with overlapped borders are
correlated to create seamless image mosaic. |
|
 |
| Image Merge and Overlay: The image merge function allows
you to combine multiple images interactively to create image
overlays or mosaics. |
|
Colorize Grayscale Images using a Low Resolution Color Image:
R2V's image fusion technology provides a powerful way to
colorize a high resolution grayscale image using color information
from a low resolution multi-spectral image. If you need to interpret
a grayscale image at a higher accuracy, colorizing the image gives
you the correct information about water, shadow, and vegetation,
instead of just dark pixels. |
| 3D Display With Image Draping: Create a 3D data set
automatically from your labeled line data and display them using
R2V's advanced 3D display and animation function. View your data
with image draping in 3D at any angle and distance. Supports 3D DEM
(compatible USGS DEM format) and Grid formats for both input and
output. 3D models can be exported to DXF, VRML, and XYZ formats.
|
| System Requirements: R2V has native versions for all
windows platforms including Windows 9X/NT/2000/ME/XP. The software
requires a Pentium class PC or better and 16MB RAM minimum (64MB or
more recommended for the best performance processing large size
images). |
