Lacounty-Mapviewer

Webject developed the Map Viewer/Query application for the data available in Arc View Shape files. The scope included digitization of the drainage maps. The user will query in ArcView and the images will comeup in a Visual Basic viewer. The user can query based on TBM Page, Drainage Map Number, Location Info, Basin or Canyon name etc. An avenue script was written that identifies the query parameters and passes on the information to the Visual Basic application. The Visual Basic Application uses the Map Objects ActiveX control for loading the relevant raster images in the Map Viewer container. As and when the query parameters change the Map Viewer container application is updated accordingly. The user will be able to zoom in, zoom out, and pan the images.
