"Our Mission is to create software applications for the internet that enable people to work together in a collaborative manner." The FAST System (Field Automation for Sanitation Trucks) is an exciting new application for managing sewer maintenance work orders and the associated facilities data and deploying that data to the field. When engineers and operators at Georgia Power Corporation (GPC) need maps or reports about their electrical distribution network, they turn to the Distribution Viewer As is the case with most energy companies today, FirstEnergy Corp of Akron, Ohio, looks at operational efficiency as the key to financial performance improvements and shareholder profit. NaviGate Tour Scanned ImagesOne of the most powerful features of the NaviGate application framework is the ability to display scanned images in the map window. Examples are aerial photographs, satellite images and engineering drawings. NaviGate allows users to selectively display raster-scanned images as layers in the map display. Gatekeeper Systems has built several NaviGate applications that access scanned images and CAD drawings. The integration of these non-GIS objects into a vector-based mapping application can be a very effective means of distributing important information to the users who need it. Raster images such as digital orthophotography and scanned paper maps can also be used as underlays in maps and as downloaded files. Viewing Scanned Paper MapsAs an example, the image below displays the map window portion of the full screen from a NaviGate application developed for a gas utility. This basic map shows building outlines, street right of ways, gas pipelines, valves and other facilities.
The utility has scanned atlas maps for this area that are engineering drawings which are labeled by hand with detailed information about their facilities. These drawings were scanned and the images inserted as layers into the application.
Viewing Aerial PhotosAnother type of raster image that can be used with NaviGate is aerial photographs. These might be digital orthophotographs taken from aircraft or satellite images. The map display below shows an intersection with parcel outlines (gray), building outlines (blue), and other structure outlines (pink) such as swimming pools, fences and retaining walls.
This image changes dramatically by viewing the aerial photograph layer underneath.
Access to CAD DrawingsGatekeeper Systems has also built applications to deliver CAD drawings as part of NaviGate maps. There are three principal ways to accomplish this task. All three methods require that the downloaded images be cataloged carefully so that the Web application can locate the appropriate drawing.
