Understanding Vectorization
Vectorization is a critical process in cartography that transforms raster images, such as scanned maps, into vector data. This conversion allows you to extract physical and cultural features and represents them as editable vector layers, enhancing your mapping projects.
What Is Vectorization?
Vectorization involves converting raster images into a format that can be manipulated easily. You can think of it as a form of image processing where pixels are transformed into geometric shapes, lines, and curves. By using software like Adobe Illustrator or Inkscape, you can trace features like roads and contour lines, creating clean, scalable graphics that retain detail regardless of size.
Importance of Vectorization for Scanned Maps
Vectorization is essential for improving the analysis and searchability of scanned maps. It lets you query and edit map features at a detailed level, making this data invaluable in GIS and CAD applications. Unlike raster images, which can become pixelated when scaled, vector data maintains its clarity and precision, allowing for effective geographic information analysis and visualization.
