Patent number: 7190377Abstract: Systems and methods for georeferencing digital raster maps by assigning points on the raster map with geographic coordinates corresponding to points on a georeferenced vector map or another georeferenced raster map. The raster map and a corresponding vector map are simultaneously displayed to a user, wherein the user then locates a common geographic point or feature on each map, and marks each of them as a unique point-pair. When the user has marked at least two point-pairs, the system then computes a georeferencing function, based on the pixel-coordinates of the points marked on the raster map and the corresponding geographic coordinates of the points on the vector map. Thereafter the geographic coordinates of any point on the map may be easily computed. The preferred embodiment provides that as more point-pairs are identified, the georeferencing function is modified for increased accuracy.Type: GrantFiled: March 29, 2001Date of Patent: March 13, 2007Assignee: SourceProse CorporationInventors: Dan Martin Scott, Darin Wayne Higgins

Patent number: 7167187Abstract: A method, computer-readable medium and apparatus for georeferencing a raster map. A first map is displayed in one area of a display, wherein the first map is a digital raster map. A second map is displayed in a second area of the display, wherein the second map is a georeferenced map that displays at least a portion of an identical geographic region displayed in the raster map. A user selects a point on the first map, and then selects a point on the second map, wherein the point selected on the second map corresponds to the point selected on the first map. Next, a geographic coordinate associated with the point selected on the second map is assigned to the corresponding point selected on the first map. These operations are repeated, i.e., selecting a point on the first map, selecting a point on the second map and assigning a geographic coordinate at least a second time.Type: GrantFiled: March 29, 2001Date of Patent: January 23, 2007Assignee: SourceProse CorporationInventors: Dan Martin Scott, Darin Wayne Higgins

Patent number: 7161604Abstract: A system and method for coordinated manipulation of multiple displayed maps, even when the maps use different internal coordinate systems. According to this embodiment, each map image to be displayed is first georeferenced, to provide a set of conversion functions between each map's internal coordinate system and a geographic coordinate system, which is latitude/longitude in the preferred embodiment. After this is done, any point on each map can be referenced using the geographic coordinate set. Since this is the case, the maps can now be manipulated, edited, and annotated in a synchronized manner, by defining the manipulations in terms of the geographic coordinate system, and using the georeferencing functions to translate the manipulation to each map's internal coordinate system.Type: GrantFiled: March 29, 2001Date of Patent: January 9, 2007Assignee: SourceProse CorporationInventors: Darin Wayne Higgins, Dan Martin Scott

Patent number: 7038681Abstract: After FEMA paper flood maps are scanned into a computer system, they are each displayed side-by-side with the relevant portion of a stored vector map covering the geographic area covered by all of the FEMA maps. During display, corresponding points, or “point-pairs,” on each map are marked by a keyboard or mouse device. The corresponding points may be such artifacts as roads, stream beds, railroad tracks, intersections of the foregoing, buildings, mountain peaks, etc., which are identifiable on each displayed map. When two point-pairs are marked, a stored algorithm calculates georeferencing functions which permit translation of the x,y coordinates of the raster map to the latitude,longitude coordinates of the vector map and vice versa. As more point-pairs are marked, the georeferencing functions are refined. Another algorithm removes apparent “bad” points from the georeferencing calculations, which points may re later used if it appears that they are not bad.Type: GrantFiled: April 22, 2002Date of Patent: May 2, 2006Assignee: SourceProse CorporationInventors: Dan Martin Scott, Darin Wayne Higgins

Patent number: 6842698Abstract: After FEMA flood maps are scanned and converted to raster maps on a computer system, they are georeferenced. The georeferenced raster maps are stored on the system. Map inset polygons are surrounded by a virtual bounding box and a determination is made whether each grid rectangle intersects any bounding box. For each such intersection, the relevant inset polygon is traced to determine if it actually intersects the grid rectangle. If there is such intersection, the inset polygon is added to a list attached to the grid rectangle. At the end of the process, the list for each grid rectangle identifies each inset polygon intersected thereby. When an address of a property subject to a flood zone determination is entered into the system and geocoded, the grid rectangle containing the address is immediately called up. If only one inset polygon is on the list, it is used to make the flood determination.Type: GrantFiled: October 10, 2003Date of Patent: January 11, 2005Assignee: SourceProse CorporationInventors: John Willard Howard, Dan Martin Scott, Darin Wayne Higgins

Patent number: 6678615Abstract: A method, system and apparatus for evaluating a characteristic or trait present at a geographic location in a plurality of non-georeferenced maps. In operation, the method comprises constructing a virtual bounding box around each inset of the maps, and then defining a virtual rectangular geographic grid system covering the total area covered by the maps. For each grid rectangle that intersects an inset bounding box, tracing the inset enclosed by the bounding box to determine if there is intersection of the grid rectangle and the inset. If there is intersection of a grid rectangle and an inset, adding the identity of the inset to a list associated with the grid rectangle, geocoding the location of the geographic location, and examining the insets contained in the list associated with the one grid rectangle containing the geocoded location, and performing the evaluation.Type: GrantFiled: April 23, 2002Date of Patent: January 13, 2004Assignee: SourceProse CorporationInventors: John Willard Howard, Dan Martin Scott, Darin Wayne Higgins

Patent number: 6631326Abstract: A system and method for performing flood zone determinations using scanned, georeferenced, digital raster map images. The user, to determine the flood zone classification of a particular property, first enters the street address, or full legal address, into a data processing system. The system determines, from the address, which raster map includes that particular property. The system retrieves that map, and utilizes georeferencing information to locate the property on the raster map. The user can visually verify the location of the property as marked on the displayed raster map, and can at that point examine the flood zone indications on the raster map. Further, the system can compare the geographic coordinates of the property against a database of flood zone boundaries for an automated flood zone determination. The system can also generate, store, and produce flood zone certificates according to the flood zone determination.Type: GrantFiled: March 29, 2000Date of Patent: October 7, 2003Assignee: SourceProse CorporationInventors: John Willard Howard, Dan Martin Scott, Darin Wayne Higgins

Publication number: 20030052896Abstract: An originally non-georeferenced raster map, which may have resulted from scanning and storing a non-georeferenced paper map, is georeferenced with reference to a georeferenced map, such as a vector map. Points denoting common features, such as road intersections, on each map are captured as point-pairs. When two point-pairs have been captured, a computer system calculates two functions, one converting the x,y coordinates of the raster map to the lat,lon coordinates of the vector map, the other converting lat,lon to x,y. Thereafter, the maps may be viewed simultaneously—top-and-bottom, side-by-side—or quasi-simultaneously, for example, toggling rapidly back and forth. The georeferencing functions are used by the system to effect manipulation of one map as the other map is manipulated. Thus, any manipulation of the vector map—scrolling, zooming, etc,—by a user is mimicked by the raster map.Type: ApplicationFiled: April 22, 2002Publication date: March 20, 2003Inventors: Darin Wayne Higgins, Dan Martin Scott
