IndianaMap Cadastral Cloud Implementation
Award Number G12AC20138, Category 7: Geospatial Platform Cloud Service Testbed
The primary objective of this project is to evaluate the technical issues, opportunities, and costs associated with deployment and geoprocessing of IndianaMap Cadastral data in Amazon Cloud Platforms. The IndianaMap portals were developed to provide a central single-source repository of data to support transportation planning, economic development, environmental assessment, and emergency response. The Indiana Office of Technology (IOT) working with the Indiana Department of Homeland Security (IDHS), and the Indiana Geographic Information Council (IGIC) have developed a strategy for creating a seamless parcel map for Indiana. Indiana IOT harvests parcel data from county web feature services monthly. The process includes integrated Spatial ETL (Extract, Transform, and Load) tools to build a seamless state-wide parcel feature class. Currently 85 of 92 counties containing 3,225,000 parcels are included in the statewide layer.
They tested Amazon-based deployments of GeoServer and ArcGIS Server. In order to obtain user feedback of the cloud-based geospatial server implementations, we developed a parcel search query application by defining a circular buffer around a given point. Upon execution of the query, the search results were displayed and analyzed for parcel property characteristics and attributes. For the GeoServer implementation we performed a comprehensive benchmark testing. They randomized the point location and the radius of the buffer in order to simulate the parcels search query application and performed this test an arbitrary number of times. For the ArcGIS Server implementation, with the participation from the Indiana Geographic Information Council (IGIC) membership, they performed queries and submitted the survey results via Survey Monkey and email.
