The committee has generated its strategic plan for 2013 (www.igic.org/committees/2013committeeplans.pdf).

August 16, 2012

A joint Ortho & LiDAR Workgroup meeting was held on July 31, 2012. Jim Sparks and Brad Fugate updated the group on the progress of 2012 ortho and LiDAR efforts. Jim Sparks discussed 2 progress maps below; one on ortho production, the other on hydro-flattening DEM production:

Jim reported that all 2012 Floyd Co. files [2012 Pilot Area] are finished except for final file integrity checks. Noble and Whitley will be finished in a week. 14 others will be posted for QC in the next few weeks; with all data posted by the end of the year. The exception is part of Block 7. Some of the LiDAR was not flown in 2012 (due to leaf-out). Orthos in those areas will be adjusted to 2005 DEMs.

Phil Worrall talked about how the OpenTopography (OT) program at the University of California San Diego will host our LiDAR and DEMs. There is a one-time fee to load and host the data. A beta-version of the Indiana frontpage has been developed and ready for testing.

OT has reprojected all Indiana data to WGS84 with the vertical units in meters. Their system allows the user to define an output projection (SPE/SPW or UTM Zone 16 Meters). Tools include zoom to map, and auto set bounding box; it estimates the number of points in the selection. Output can include specific classified points or all points, and a user can specify DEM, grid resolution, visualization (light source) & output format. It was noticed by the group that the example was NAD27. Members were asked to test the site.

Jim Sparks outlined some of the thinking about the 2014-2016 ortho program. The plan is to conduct several roadshows across the state. First steps will be several meetings with GIS professionals to gain a feel for needs, added value products, costs, and partners. Then the plan is for roadshows directed at policy makers and funders. There will be a session to talk about the next 3-year ortho cycle at the upcoming “Local GIS Coordinators Forum” (September 20 at the Hamilton Co. 4H Fairgrounds in Noblesville).

Phil Worrall and Dave Nail discussed the National Enhanced Elevation Assessment sponsored by USGS (and written by Dave Maune at Dewberry) and the National Enhanced Elevation Program. Think of this program like “Elevation for the Nation”, where the continental US will get LiDAR sufficient for creating 1-foot contours (0.7-meter post spacing). The whole report and summary fact sheets are available on line. The 3DEP (3D Elevation Program) is similar to NAIP, with options and derivative products. Cost for the program is $140-million per year (11 federal agencies paying $10-million/year each, and the rest from States). USGS is in process of selling the program to the other agencies. Phil Worrall participates in the monthly calls of the National Digital Elevation Committee, and noted that all players on the committee support the program. He displayed a letter of support from NSGIC. The NDEP document of “Guidelines for Digital Elevation” (first written in 2004) has been recently updated by NDEP and ASPRS (in 2011) and submitted for review. The 3DEP plan is for a reflight cycle every 8 years. The hope is to start in the FY2013 budget year.

The Workgroup did not meet during this period, but work on setting up the OpenTopography server at UCSD continues. IGIC staff is also working on the new IndianaView mini-grant to develop the new tri-fold Unofficial Guide to the IndianaMap & OpenTopography server, as well as creating new IndianaMap Postcards featuring the new Ortho and LiDAR datasets for Indiana.

 

April 19, 2012

The Elevation Workgroup only met once this period and that was a combined Elevation / Ortho Workgroup meeting (2/21). The following topics were discussed:

  1. Ortho-LiDAR education events (workshops, webinars, etc.)
  2. Ortho-LiDAR Program updates (2011 & 2012 Status)
  3. ISDP and OpenTopography hosting of 2011 data
  4. Data Sharing Committee plans for 2012
  5. Joint committee planning for 2012

We also talked about ideas for the IndianaView grant including 1.) Develop a new tri-fold Unofficial Guide to the IndianaMap & OpenTopography, 2.) Creating new IndianaMap Postcards, 3.) Developing an IndianaMap phone app, and 4.) Creating IndianaMap Bookmarks

After this meeting Jennifer Dubeansky developed and submitted a proposal to IndianaView for the first 2 items listed above.

 

February 16, 2012

The workgroup determined goals for the upcoming year. WE plan to use lessons learned from the ISPLS workshop to develop additional workshops for the GIS user community regarding LiDAR data acquisition plans, accessibility using OpenTopography, proper uses of data, etc.

 

December 8, 2011

The workgroup met on November 22 and welcomed a new member, Jinha Jung, a post-doctorate student from Purdue University specializing in LiDAR. The workgroup also shared information regarding the state’s LiDAR delivery schedule, IGIC’s LiDAR Server opportunity with OpenTopography and the LiDAR Workshop presentation at the ISPLS Conference on January 20, 2012.

 

October 20, 2011

The workgroup met on September 23rd, and shared information regarding the state’s LiDAR delivery schedule, IGIC’s LiDAR Server opportunity with OpenTopography and the LiDAR Workshop presentation at the ISPLS Conference in January 2012.

April 28, 2011

Members of the Elevation Workgroup have been actively working with the GIO to support the specifications and funding for the new Statewide LiDAR collection project. The Workgroup met on April 24 to plan continuing support for this statewide program. Chris Morse, USDA – NRCS announced that his agency would be contributing a little over $50,000 to this year’s Ortho & LiDAR program.

David Nail moderated a hands-on workshop at this year’s conference on Using LiDAR Point Cloud data. This presentation will become the template for conducting LiDAR Roadshows around Indiana as the new LiDAR data is delivered beginning later this year.

Our Workgroup’s next priority is to develop a LiDAR 101 Roadshow. We will also be developing an Advanced LiDAR Roadshow syllabus to be presented later this year to address use of LiDAR point-cloud data and advanced applications, but our initial focus will be on the LiDAR 101 Roadshow.

We are planning these Roadshows to be full-day seminars. The morning session will be lectures/demos covering all the basics of the new Elevation [and Imagery] data products, including dos and don’ts! The afternoon session will be hands-on training for using this new data. Folks wanting the general information can just attend the morning session. Those wanting the technical details can stay for the afternoon hands-on session.

Members of the Elevation Workgroup have been actively working with the GIO to support the specifications and funding for the new Statewide LiDAR collection project. David Nail is moderating a hands-on workshop at the 2011 Indiana GIS Conference on Using LiDAR Point Cloud data. This presentation will provide a template for conducting LiDAR Roadshows around Indiana as the new LiDAR data is delivered beginning later this year.

December 6, 2010

The Elevation Workgroup met on November 30th to discuss the looming Statewide LiDAR collection project, the current results of our Statewide Elevation data survey, a USGS partnership grant proposal to help fund the LiDAR collection project, and a hands-on workshop the group is planning for the Using LiDAR Point Cloud data at the annual GIS Conference.

October 21, 2010

The Elevation Workgroup did not meet this period, but the workgroup finalized the statewide elevation survey/questionnaire, and it is currently available to take on Surveymonkey. The survey was announced to the user community by IGIC, and currently we have over 100 responses to the survey. To take the survey click on the following link: http://www.surveymonkey.com/s/6G7VKRT
