The Survey Plan Online Checker (SPOC) is a custom geo-processing ser- vice that imports CAD files and performs various business rule checks to validate content and formatting. Developed as a Rich Internet Application, it leverages GIS technology to provide users with spatial analysis, data management and mapping functionality. Esri's ArcGIS for Server technology serves as SPOC's map engine and provides the integrated map view, while an Oracle SDE Enterprise Geodatabase houses supporting features. Using this tool, surveyors can submit their CAD files through a Web-based interface; the content is automatically checked to ensure that the file conforms to the required layer and element struc- tures. A spatial overlay module ensures the CAD file is spatially geo-referenced in accordance with provincial legislation. The dimension checker module identifies closure errors prior to registration. The user is also able to view their plan relative to the complete and current cadastral fabric for Alberta. This visual map component enables the user to readily identify plan anomalies or conflicts prior to submission to Alberta Land Title Registries, which can save the surveyors and their clients thousands of dollars. Once a plan is submitted and registered at Alberta Land Titles, it is integrated into the cadastral fabric in near real time and can then be accessed online using the Alberta Registries Spatial Information System (SPIN 2), which allows for the province-wide search, view and download of registered plans of survey. Automating Quality Assurance The integration of SPOC has effectively moved the quality assurance process for digital CAD files closer to the source— the Surveyors. This in turn saves time at the Land Titles Office and improves the quality of registration documents. The cadastral system developed by SDW/AltaLIS has essentially become the most advanced system of its kind in the country, with a unique ability to continuously improve its quality and accuracy as new plans are added. As a result, operational data maintenance and management costs are significantly reduced, and there is a much faster turnaround for cadastral fabric updates. SPOC was released to the user com- munity in the spring of 2010 and all surveyors submitting plans to Alberta Land Titles are utilizing the service to validate and improve the quality of their survey plan file submissions.
