Automatic conflation systems and techniques which provide vector-imagery conflation and map-imagery conflation. Vector-imagery conflation is an efficient approach that exploits knowledge from multiple data sources to identify a set of accurate control points. Vector-imagery conflation provides automatic and accurate alignment of various vector datasets and imagery, and is appropriate for GIS applications, for example, requiring alignment of vector data and imagery over large geographical regions. Map-imagery conflation utilizes common vector datasets as “glue” to automatically integrate street maps with imagery. This approach provides automatic, accurate, and intelligent images that combine the visual appeal and accuracy of imagery with the detailed attribution information often contained in such diverse maps. Both conflation approaches are applicable for GIS applications requiring, for example, alignment of vector data, raster maps, and imagery. If desired, the conflated data generated by such systems may be retrieved on-demand.

Devices, systems and methods are disclosed which relate to optimizing a minimum cost function associated with buried asset lines by using a GIS application to generate a “dynamic buffer” around each asset line based on a risk management algorithm. A risk management algorithm, by which a GIS application can generate a “dynamic buffer”, is employed to minimize asset line damage risk and operating costs by balancing potential costs from damage against the fixed labor costs of manually screened and located tickets. Embodiments of the invention utilize the geography of the situation as well as factors for the asset itself.

A portable, aerial, dual-swath photogrammetric imaging system comprising twin nadir pointing CCD cameras for simultaneously acquiring twin adjacent digital images for merging into a large panorama. A pair of lens shifters symmetrically shift twin images to the left and right sides of the focal points of two parallel lenses to extend imaging swathwidth. The twin adjacent images of the imaging system have a strip of narrow overlap at the center of the whole scene that are reserved for photogrammetric processing and stitching twin images into a seamless panorama. Each camera is connected to an embedded computer which controls imaging data acquisition, attaches GPS/IMU measurements, generates KML metadata files for its snapshots, and stores acquired images and metadata into removable SSDs. Direct geo-referenced panoramic digital stills are immediately registered on to Google™ Earth precisely. Its images can be further processed for advanced mapping, change detection and GIS applications.

A method, apparatus, and article of manufacture provide the ability to update a drawing surface in a CAD/GIS computer application. First, a drawing surface is displayed in a CAD/GIS application. A surface edit operation is then performed on the drawing surface. The CAD/GIS application then determines if an automatic rebuild option is active. If the rebuild option is active, the drawing surface is dynamically and automatically rebuilt to reflect the surface edit operation. Alternatively, if the automatic rebuild option is inactive (e.g., toggled off), the drawing surface is flagged as out-of-date.

Methods and systems for aggregating points into segments to facilitate measurements relating to GIS polylines and/or polygons are provided. According to one embodiment, a request for information is received regarding a shape representing a geographic feature displayed within a geographic information system (GIS) application. One or more measurement segments are programmatically identified by selecting multiple measurement vertices from a set of points associated with the shape based on one or more predetermined selection criteria. The remaining intervening points of the set of points not selected as measurement vertices define sub-segments of the measurement segments. A length of each of the measurement segments is then calculated and displayed by summing corresponding sub-segments.
