LiDAR Technology - Introduction and Applications
Friday, February 1, 2013 1:00 AM - 2:00 AM EST

Join us for a conversation with Dr. Bharat Lohani, IIT Kanpur

Dr. Lohani is an Associate Professor in the Dept of Civil Engineering at IIT Kanpur, a premier engineering institution in India. His research interest includes LiDAR data capture and processing for various applications ranging from infrastructure to archaeology. 

The last decade has seen multifold growth in LiDAR technology world-wide. This technology has, to a large extent, replaced the conventional surveying techniques in several domains. This technology uses a laser beam or pulse to measure large number of points over the surface of a terrain. Highly accurate and dense measurements are carried out at a high speed. The resulting 3D point cloud along with the intensity information for each point is a valuable data for several applications. Laser scanning can be carried out by stationary and mobile platforms, which enable data collection in difficult scenarios and under varied field conditions. This talk will, however, focus on airborne LiDAR technology. 

This webinar will first discuss the basic principle of LiDAR technology and then describe the different applications that are now possible with this technology. The webinar will be useful for professionals who have some understanding of remote sensing, GIS or mapping technologies and are keen to use LiDAR technology in future. The talk will aim at providing basic information that are useful to a user of LiDAR technology including basic principle, data collection and processing steps, error sources and attainable accuracies. A list of applications will be introduced with detailed discussion on a few. In addition, links will be provided to further resource material, commercial and free software, available data and prevalent LiDAR survey standards.

Gigapans - What are They and How are They Useful in GIS?
Thursday, February 7, 2013 1:00 AM - 2:00 AM EST

Join us for a conversation with Michael Franz, GigaPan.
 
Gigapans are gigapixel panoramas or digital images with billions of pixels. These enormous panoramas have fascinating detail, all captured in the context of a single brilliant photo. Gigapixel images allow photographers to get “up close and personal” with each image they take and offer them a new way to deliver content in the advertising, sports, education, geology, life sciences and outdoor photography industries, and more.
 
GigaPan gives photographers the technology to easily create high-resolution panoramic images, as well as upload the large images to GigaPan.com to view and explore. GigaPan EPIC robotic camera mounts can capture hundreds of photos using almost any digital camera. Our stitch software allows you to automatically combine the thousands of images taken into one highly detailed image with amazing depth and clarity. Gigapan.com offers the ability to view and explore images directly on our website, or you can embed our viewer application onto a third-party website. 
 
A tool that enhances communication, exploration and learning, the GigaPan user-base is diverse and global. Artists, scientists, humanitarians, students and educators are among the most prevalent users. In India, GigaPan can be used to explore landscapes, outcrops and microscopic details of rocks and minerals. It can be used in stadiums, or at national heritage monuments and landmarks to get a clear and in-depth detail of the place.
 
The ability to capture a scene in such high resolution enables viewers to virtually explore and learn about landscapes that might not otherwise be accessible due to weather, geography, handicap, etc. GigaPan provides a way to collect accurate photos for GIS and mapping.

Journal News Removes Interactive Gun Permit Map

The Lower Hudson Journal News has been under fire for publishing a map of gun permit holders in two counties in New York State  before Christma. (APB coverage 1, 2, podcast). On Friday January 18 the paper removed the interactive map. Why? Publisher Janet Hasson gave answers in a media statement and in a letter to readers.

In a statement in response to The Poynter Institute (a journalism school) she argued:

With the passage this week of the NYSAFE gun law, which allows permit holders to request their names and addresses be removed from the public record, we decided to remove the gun permit data from lohud.com at 5 pm today. While the new law does not require us to remove the data, we believe that doing so complies with its spirit. For the past four weeks, there has been vigorous debate over our publication of the permit data, which has been viewed nearly 1.2 million times by readers. One of our core missions as a newspaper is to empower our readers with as much information as possible on the critical issues they face, and guns have certainly become a top issue since the massacre in nearby Newtown, Conn. Sharing as much public information as possible provides our readers with the ability to contribute to the discussion, in any way they wish, on how to make their communities safer. We remain committed to our mission of providing the critical public service of championing free speech and open records.

In a letter to readers published on Friday she wrote:

So intense was the opposition to our publication of the names and addresses that legislation passed earlier this week in Albany included a provision allowing permit holders to request confidentiality and imposing a 120-day moratorium on the release of permit holder data.

She goes on to say that during the 27 days the map was online any one interested would have seen it and that the data would eventually be out of date. She also noted that the paper does not endorse the way the state chose to limit availability of the data.

The original map/article still includes a graphic - but it's a snapshot, a raster image, with no interactivity. Says Hasson in the letter to readers:

 And we will keep a snapshot of our map — with all its red dots — on our website to remind the community that guns are a fact of life we should never forget.

I continue to applaud the paper for requesting the data via a Freedom on Informat request, mapping it, keeping the map up despite threats and criticism and now responding to state law. I think the paper did a service to the state, to citizens and to journalism.
