Combined with the raster-vector conversion library and the calculation function for plot area and
the automatic link generation function for text and figures (html),
there are development achievements for various applications for cadastral maps and land area maps.
After extracting the text from the land area map all at once, it is recognized by automatically estimating the tilt. The surrounding line shapes do not affect the recognition results as they are on separate layers. Mistakenly recognized parts can also be easily corrected using mouse operations.
The recognition time for a land area map of A3 size and 400dpi is 2 seconds(Core2 Duo) to 5 seconds(Pentium-M) with 135 segments.
The polyline to polygon conversion takes only a moment.
