Service to Access and Visualize the Data Alignment Layer
The on-line service established by this project will do two things. First, it will offer a search mechanism that will enable users to search the Canadian Data Alignment Layer (CDAL) of the Canadian Geospatial Data Infrastructure (CGDI) in a new way. At present, users can search the CDAL only by using geographical names or National Topographic System (NTS) numbers. With the new service, users will be able to define their own region of interest within the boundaries of a rectangle specified by latitude and longitude. This user-friendly search mechanism will greatly simplify and enhance access to the CDAL, both for human users and for on-line applications that want to interface with the CDAL. The second purpose of the project is to visualize the specified CDAL points and generate rasterized image chips that depict the requested points. This service will particularly benefit RADARSAT International Inc. in its production of geocoded satellite imagery. Currently, precision geocoding is largely a manual process, with ground control often expensive and difficult to obtain. The new Web service will make geocoding more streamlined and less expensive. Accurate geocoding can lead to broader applications as well. For instance, it can enable aerial photography and satellite imagery to be superimposed on maps and GIS data, creating new applications and services in such fields as real estate and land information.
