Indiana Geological Survey’s Petroleum Database DBMS and GIS Prem Radhakrishnan, Charles W. Zuppann 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Overview ► Indiana Geological Survey is a state organization with the responsibility to collect and disseminate oil and gas data to the industry and research organizations. ► The data collected for the well borings in the state of Indiana comes from a variety of different sources. ► The data includes complex information that has to be organized and distributed. 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 History It always starts with paper, the survey still maintains paper data of all the borings in the state organized into filing cabinets ► In the mid-nineties an access database was designed to bring the data into the computer age. ► The need for simultaneous access by multiple users and distribution of the data over the internet facilitated migration of the data into server and web technology i.e. SQL Server© and ColdFusion© ► Also the spatial aspect of the data drove the need for GIS specifically the use of ArcMap© in house with custom extensions and the use of ArcIMS© to distribute the spatial data. ► 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Data Organization ► The data is maintained in a Microsoft SQL server© with a number of applications facilitating access to the data A ColdFusion© web application allows viewing and editing of the tabular data within the organization A custom extension for ArcMap© allows viewing and editing of the data spatially. Another ColdFusion© web application allows the public to query and download the data. The ArcIMS© web application (which uses Flash© technology and server side ColdFusion© components) allows the public to view the data spatially. 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Interoperability ► The data is contained in multiple tables in the database. One of the tables which is the primary table with unique ids for each well contains the UTM X and Y coordinates as attribute information. ► Whenever data needs to be displayed in GIS it is done in two ways A dynamic XY Event Layer is created whenever the purpose is only display A dynamic shapefile is created whenever the data needs to be edited. The custom extension updates the SQL server table attributes when something is changed within the ArcMap environment. 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Technology Used ► Database Microsoft SQL Server© to store the data Custom Visual Basic© DLL to perform some custom functions on the database ► GIS ArcObjects© to create the custom extensions / scripts for ArcMap©. ArcMap© for data display and editing 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Technology Used (contd..) ► The World Wide Web ColdFusion© is the main server side technology used. ►To create the web application for displaying and editing tabular information. ►ColdFusion© components were created to interact and retrieve information from ArcIMS©. ►Flash Remoting© was used to enable flash to communicate with the ColdFusion© components. 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Where do we fit in? ► Databases of GIS have always been the backbone Attention must be given to databases that do not have a major spatial component. The general public does not understand the meaning of “GIS” and still needs to harness the power that we “GISaholics” can provide them. 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 ColdFusion 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 Flash IMS 03.09.2004 Indiana Geological Survey Indiana GIS Initiative Conference 2005 That’s it Folks!!! ► The website address is http://igs.indiana.edu/pdms ► My email [email protected] ► Questions 03.09.2004 ?
