    Able Software R2V 7.0


    If your contour maps are in color and scanned as color images, use R2V's Image/Classification to purify the colors into a smaller number of colors. The Image/Image Pixel Tool can be used to merge colors and convert one color to another. You can then vectorize the contours by specifying the brown color and other colors separately using R2V's Vector/Auto Vectorize function.

    If your image is scanned as grayscale (this is recommended when map quality is not very high), use the Image/Set Image Thresholds command to select the best thresholds for contour lines, and then Vector/Auto Vectorize to trace all contours automatically.

    If your image is 1-bit black and white, you can use Vector/Auto Vectorize to get all contour lines traced automatically.






    DIGITIZE PARCEL/TAX MAPS
    If your parcel map is scanned as a 1-bit black and white image, you can go ahead and use Auto Vectorize to get all parcel boundaries vectorized automatically.
    Use R2V's Line Editor to clean up the vector lines and update broken boundaries.
    Use Vector/Create Polygon Layer function to close all polygons.






    VECTORIZE SOIL/FLOOD MAPS USING R2V
    SOIL MAP VECTORIZATION


    If your soil map is scanned as a 1-bit black and white image, you can Auto Vectorize to get all parcel boundaries vectorized automatically. If your soil map is drawn on an aerial photo, scan the image as grayscale.
    Use Image/Set Image Threshold to separate the lines from the background or use Image/Remove Background to clean up the background.
    Select Vector/Auto Vectorize to trace all the boundary lines automatically.
    Use the Vector/Create Polygon Layer function to close all polygons






    VECTORIZE AERIAL PHOTO/SATELLITE IMAGERY USING R2V


    Aerial photos and satellite imagery provide the rich information source for computer mapping and map creation.
    You can use R2V to extract vector boundaries from aerial photos or satellite imagery or trace streets and roads.
    If your image is classified, the Vector/Auto Vectorize command can create map layers for all classes with just a single command.
    Here is an example of a map created from SPOT imagery:






    CREATE 3D DEM FROM CONTOURS






    R2V CONVERTS CAD DRAWING TO VECTOR FORMAT AUTOMATICALLY

    R2V's powerful Auto Vectorize function converts CAD drawings to DXF, IGES, and other formats in just a few seconds.

    R2V supports multiple layers exactly the same way as CAD systems do.

    R2V can handle very large size drawings. One major aircraft manufacturer has used R2V to vectorize a 180" by 48" drawing with just a single command. They tried other packages but R2V is the only one that does the job.

    If you have a large number of drawings, you can use R2V's batch processing function to process them together with one command.






    IMAGE PROCESSING

    ADVANCED IMAGE PROCESSING: IMAGE REGISTRATION, GEO-REFERENCING, AND IMAGE MOSAIC
    IMAGE REGISTRATION AND WARP
    R2V allows you to register one image against another image by using 4 or more control points.
    Image warp can correct map or image distortion so that two images can be overlaid on top of each other.
    R2V supports bi-linear or triangulation based methods for image registration.






    GEO-REFERENCING IMAGES WITH R2V:
    GeoTIFF: supported by many image processing and GIS packages
    World File: supported by all ESRI products and other packages.
    TAB File: supported by MapInfo and other products.
    R2V's own control points method.

    IMAGE MOSAIC
    R2V's Image/Mosaic function allows you to stitch a group of images together to create a mosaic image. Images with overlapped borders are correlated to create seamless image mosaic.
    This function can be used to merge small image sections together when using a small format scanner.
