"Image Vectorization of Road-Dense Satellite Datasets"

    Short description

Data extraction of geo-spatial objects from satellite images is an important processing step in enabling data analysis on geo-spatial or spatio-temporal data, which commonly composes of line (road) and polygon (area) layers. Unfortunately, the traditional method is often inaccurate in extracting roads from other objects if there are many roads in the satellite image. In this paper, we present a technique for converting satellite data (raster images), that contains several roads, in the form of pixels onto the form of spatial objects that contain lines and polygons. There are three main steps in our algorithm. First, roads are extracted from other objects by employing k-means clustering. Second, the line extraction is applied only to the road areas by using morphological operation to skeletonize the image, and then, enhancing the result by using bag packing and Ramer-Douglas-Peucker algorithms. Finally, polygons can be extracted by applying land-cover classification only to non-road objects.

    Scope of your works
        what you plan to do with this topic?

The experiments showed that lines (road networks) and polygons (areas) can be accurately extracted out of satellite imagery, simultaneously.

    how do you plan to collect measurement data?

Comparison between the correct image (As if it were 100 percent accuracy) and images from my program.

    will you use simulation or model?
