Paper map and scanned map are the traditional way of map preservation. These methods make spatial query and analysis difficult. It is necessary to vectorize these maps to facilitate the query and analysis of historical geospatial data. However, the traditional vectorization method is time-consuming and labor-consuming, and cannot meet the actual needs. Therefore, this paper proposes an automatic map vectorization method based on boundary tracking. Firstly, the map is grayed and binarized; then the raster to

vector method is applied to the binary map; finally, based on four maps, the extraction effect of this method is compared with common methods. The experimental results show that this method can extract all map lines completely, and can effectively separate the text in the map.

Using ROC curve to validate the evaluation results, it is concluded that the ROC curve area of the spatial multi-criterion decision analysis model is 0.852, which shows that the landslide disaster susceptibility evaluation result in Fujian Province is ideal, and it is reasonable to apply the spatial multi-criterion decision analysis model to the landslide disaster susceptibility evaluation.

With the continuous development of big data technology, network data collection technology has become a popular research field. Data collection function libraries based on Python language such as Urllib, Requests, Selenium and other modules are inefficient and easy to block, and the current data collection and analysis platforms are all independent functional modules, which do not form a closed loop and have a poor user experience. In order to solve the above problems, this paper proposes a data collection

and analysis platform. First, the Scrapy framework is used to complete data collection, and then the Kettle tool is used to clean the

collected data. The processed results are saved into the MySQL database. Finally, the Flask frame is combined with Echarts technology to build a Web system to visualize the data analysis results. This paper uses Beijing Public Transport website data as a crawlertest platform. Through the collection and analysis of bus line types, bus routes and other information, and the results display, the analysis results have certain guiding significance for the planning of urban public transport. At the same time, the platform is stable, reliable and easy to operate.
