Abstract: A method for enabling raster image editing software to work with geospatial imagery includes identifying geospatial metadata for an image upon opening of the image, and monitoring all raster image editing operations performed on the image to determine if the geospatial metadata is affected. The geospatial metadata is updated if the geospatial metadata is affected by a raster image editing operation. In another aspect, a computer readable medium contains instructions for controlling a computer system to perform a method for enabling raster image editing software to work with geospatial imagery.

Abstract: A method of recovering coordinate system information for a geographic data file for which coordinate system information is unavailable. The method includes obtaining a raster image corresponding to the geographic data file, and correlating the raster image to the earth's surface. A list of probable coordinate systems for the raster image is generated, and a statistical analysis is performed for each likely coordinate system candidate. The suggested coordinate systems are then ranked using statistical analysis.

Abstract: A method for converting a source document having graphical subject matter into an interactive document includes receiving, via a user interface, input regarding information to be tagged to objects on the source document and tagging information to objects on the source document in response to the input, thereby creating interactive effects based on the tagged information. The interactive effects can include pop-ups, external e-mail and URLs, and other interactive behavioral actions. A set of files that defines an interactive document is automatically created, wherein the interactive document incorporates the subject matter of the source document and includes the interactive effects. In another aspect, a computer readable medium containing instructions for controlling a computer system to perform a method of converting a source document having graphical subject matter into an interactive document is provided.

Abstract: The present disclosure relates to electronic digital files with document security features to prevent duplication of documents. The method may include selecting a source image previously designed, where a specified tone is used to indicate a background area and another specified tone(s) is/are used to indicate at least one security feature(s) area. The method may also include selecting one or more corresponding tiles and/or one or more corresponding functions for (i) the background area and (ii) the at least one security feature(s) area, generating a converted electronic digital file from the source image with the desired security feature(s) and saving the converted electronic digital file in a format suited for use as a stand-alone graphic image or incorporated into other programs ready for output onto the output device.

Abstract: A method for transforming spatial data includes displaying a first graphical representation that represents spatial data formatted in a first coordinate system and displaying a second graphical representation that represents spatial data formatted in a second coordinate system. The data represented by the first graphical representation is transformed into the second coordinate system in response to the first graphical representation being dragged and dropped onto the second graphical representation. In another aspect, a computer-readable medium contains instructions for controlling a computer system to perform a method of transforming spatial data.
