METHOD FOR ASSISTED ROAD EXTRAPOLATION FROM IMAGERY

摘要

A method for assisted map extrapolation comppsing establishing a database of geographic images and establishing a database of geospatial datasets extracted from the database of geographic images The method provides an unskilled user interface hosted remotely or self contained withm a computing device loaded with imagery and analysis software wherein an unskilled user may select a geographic area The method supepmposes any existing data from the geospatial datasets onto the geographic images for a geographic area and displays it to the unskilled user A set of algorithm parameter controls are provided wherein the individual may teach image analysis software how to pick transportation network features such as roads or other objects such as building footprints from the imagery The geospatial datasets are then updated with the features identified by the unskilled user assisted software
