2018 ISPLS Convention – GIS Presentations

In 2018 we were pleased again to present several GIS education sessions at ISPLS’s Annual Convention in Indianapolis.  On Friday 1/19/18 we presented the following three (3) 90 minute education sessions on GIS and IndianaMap topics of broad interest to Indiana’s Surveying community.  A Dropbox hyperlink to access all of these presentations is HERE.

Session 1:  Overview and Applications of Indiana’s new statewide Digital Orthoimagery and 3D Elevation Program Data

Duration: 1.5 hours (9:30 a.m. – 11:00 a.m.)

Session Objectives:  This session will provide an update of the current statewide geospatial data collection efforts and applications using the digital data sets developed through the…

  • 2016 – 2018 Statewide Orthoimagery Program
  • 2017 – 2019 Statewide USGS 3DEP Elevation Program

These GIS data collection efforts continue Indiana’s efforts to provide access to free, high-resolution, high-accuracy, authoritative geospatial imagery and elevation data for Indiana.

Orthoimagery Program:  Since 2005, Indiana has had access to highly accurate (1-foot pixel or better) digital 4-band orthoimagery for the State of Indiana.  Since 2005 the Indiana Geographic Information Office (GIO) has managed three separate projects to collect statewide orthoimagery in 2005-2006, 2011-2013, and the current 2016-2018 collection.

3DEP Elevation Program:  Indiana’s 2011 – 2013 statewide orthoimagery project included Indiana’s first-ever collection of high-accuracy Light Detection and Ranging (Lidar) digital elevation data for Indiana.  Beginning in 2017, IGIC and Indiana’s NRCS office partnered with the USGS in their 3D Elevation Program (3DEP) to collect new Lidar and bare-earth Digital Elevation Model (DEM) across Indiana.  This discussion will provide an update on the 3DEP collection and production currently in progress across Indiana to further improve the accuracy of these datasets with a look ahead to when and where these datasets will be brought online for consumption by the public.

Finally, we will demonstrate ways in which you can access and use these digital Imagery and Elevation data in you CAD projects through inserting images, consuming web services, and generating surfaces and contours. We will also discuss how to integrate the elevation data that we generate with our field surveys and how to adjust the DEM to fit the field data.

Speakers & Bios: Jim Sparks, GIO & Chris Morse, USDA, Andrew Pursifull, P.E., USDA-NRCS

Jim Sparks, State of Indiana, Geographic Information Officer (GIO):  Jim has spent most of his career working with geospatial information. In 2007, He was appointed Indiana’s first Geographic Information Officer. He has a B.A. in Business Administration and a M.S. in Management.

Chris Morse, USDA-NRCS:  Chris is the State GIS Coordinator for NRCS in Indiana, based out of Indianapolis. He supports GIS and GPS operations in 75 field offices around the state, develops user enhancements and tools for ArcGIS using Python, and serves as one of the Federal sector representatives on the Indiana Geographic Information Council (IGIC) Board of Directors. Chris has over 17 years of experience in the field of GIS and a Bachelor of Arts in Cartography and Geographic Information Systems from the University of Wisconsin – Madison.

Andrew Pursifull, P.E., USDA-NRCS:  Andrew is an engineer on the NRCS Conservation Delivery Team based out of Huntington. This team provides technical assistance to field staff in 11 counties. He works on projects that range from grassed waterways, to animal waste storage facilities, to wetland restoration and creation. He oversees the projects from initial evaluation through completion of construction. This includes the design surveys, plan generation, construction inspection, and as-built surveys and plans. Andrew has a B.S. from Purdue University in Agricultural and Biological Engineering.


Session 2:  IndianaMap 4.0 -Using the next generation of the IndianaMap Viewer and GIS Resources

Duration: 1.5 hours (12:30 p.m. – 2:00 p.m.)

Session Objectives:  The current IndianaMap viewer application (Version 3.0) is now six years old and has become a bit outdated and archaic. The Indiana Geological and Water Survey’s IndianaMap Project Team is developing a new updated IndianaMap application. This application will take advantage of modern tools, up-to-date technologies, easy expansion for new data layers, and will reduce the effort to maintain the site. The new application also provides end users with new tools that will allow them to add their own data, add information from non-IndianaMap REST services, view attribute tables, and more.

Speakers & Bios: Chris Dintaman, Indiana Geologic and Water Survey, and Philip Worrall, Indiana Geographic Information Council

Chris Dintaman, Geologist / GIS Specialist, Indiana Geologic and Water Survey.  Chris has over twenty years of experience at IGWS working on the Indiana Water Balance Network (IWBN), the Database of Industrial Mineral Producers in Indiana, and IndianaMap Map Update, online Story Maps, and Data Download Services.  Chris provides the geospatial data and technical support for the IndianaMap viewer and its end users.

Phil Worrall, Executive Director IGIC.  Phil leads the organization’s efforts in the statewide coordination of GIS through dissemination of data and data products, education and outreach, adoption of standards, building partnerships, and IndianaMap.


Session 3:  IndianaMap Data Layers and Applications for Surveyors

Duration: 1.5 hours (2:00 p.m. – 3:30 p.m.)

Session Objectives:  This session will provide an update of the geospatial data layers available on IndianaMap of specific interest to Professional Land Surveyors, and the ongoing collection efforts and applications of these data sets…

  • County Parcel (and other) GIS Data Sharing layers
  • Current and Historic Survey Record Layers on IndianaMap

These ongoing projects continue Indiana’s efforts to provide easy and free access to these important data layers to support Professional Surveyors and many other GIS users across Indiana.

Parcels & Department of Local Government Finance (DLGF) Property Data:  In the 2016 Indiana General Assembly, House Enrolled Act 1273 addressed various property tax matters including the requirement for assessing officials to maintain geographic information system characteristics of real property parcels and to transmit that data annually to the Indiana Geographic Information Office (GIO) of the Office of Technology.  This legislation has paved the way for a new GIS County Data Sharing initiative between the GIO, DLGF and all 92 Counties across Indiana.

Now over 3.5 million GIS land parcels in Indiana can be joined with detailed County property assessment information to create a powerful tool to support the business of local and state government, surveying and engineering applications, economic development, public safety, public health, infrastructure and environmental applications, as well as many business applications these data can support.

In 2015 the GIO and IGIC developed a demonstration pilot project by joining the County GIS Data Sharing Parcels with the DLGF Property Assessment data in Esri’s Local Government Data Model.  This initial pilot not only demonstrated the feasibility to accurately join these data sets together with over a 97% match rate, but also demonstrated a wide variety of geospatial applications this combined dataset could support.

In late 2017, a new Statewide County Parcels & DLGF data database was developed to support HEA1273 as well as to leverage the success of the original pilot.  This session will share the results of this new data sharing effort and demonstrate access from IndianaMap and sample applications.

Land Surveying Layers on IndianaMap:  Historically, IndianaMap provided access to government / survey boundary PLSS data, Geodetic Control monument layers, as well as geo-referenced County Surveyor Tie-Card records from participating counties.  Through GoFundMe and other grant initiatives, IGIC is currently working with its partners on a renewed effort to update these layers and provide access to historic General Land Office (GLO) records on IndianaMap 4.0.  This session will share the results of this effort.
