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.

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.

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.

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.

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

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.

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.
