One of the issues the GIS Community often hears about is the concern over individual privacy and expanding use of locational information. In response to this issue, NSGIC - the National State's Geographic Information Council has published a new document entitled "This Isn't Private Information". This document dispels the common misconception about five widely used types of modern geospatial data and shows that they are not private.

In this new document, Ivan Weichert, NSGIC President and Kansas State GIS Coordinator says...

"there are many privacy issues being debated across the country that, if enacted in law, will destroy the government’s ability to conduct its business. In addition, some of the proposed changes would negatively affect government and commercial services that citizens expect and demand."

Will Craig, former NSGIC President and Chair of the NSGIC Outreach Committee said when his committee released this document that...

"This document is our stake-in-the-ground statement on this issue, and to "Feel free to use it whenever you think it would help."

NSGIC has published this new document in the Advocacy section of the NSGIC website - HERE.
On May 30, 2013 the US Geological Survey assumed operation of the LDCM mission from the National Aeronautics and Space Administration. Operation includes collecting, archiving, processing, and distributing data products from Landsat 8, continuing the 40 year legacy of the Landsat Project. Landsat satellites give us a view as broad as 12,000 square miles per scene while describing land cover in units the size of a baseball diamond. From a distance of more than 400 miles above the earth surface, a single Landsat scene can record the condition of hundreds of thousands of acres of grassland, agricultural crops, or forests.

Landsat 8 Products and Availability
Each day, 400 or more scenes acquired by the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) will be archived at the USGS EROS Center, and are processed to be consistent with current standard Landsat data products. Data will be ready to download within 24 hours of reception.

The Landsat 8 acquisition schedule and calendar is available here:
The standard Level 1 data and LandsatLook (full-resolution jpg) products will be available for download at no charge from GloVis, EarthExplorer or the LandsatLook Viewer.

Landsat 8 images on IndianaView
Additionally Larry Biehl, IndianaView Coordinator reports that processed Landsat 8 images for Indiana are being made available from the IndianaView web site. Each image file contains 10 channels of data representing both the OLI and TIRS sensors. The direct link to this data is: http://www.indianaview.org/glovis/Landsat8_images.html

About IndianaView
The overall purpose of IndianaView is to promote sharing and use of public domain remotely sensed image data (aerial and satellite platforms) for education, research and outreach across universities, colleges, K-12 educators and state and local governments.

Google/TIME Annual Timelapse Viewer
Google also recently released the Landsat Annual Timelapse Viewer - http://earthengine.google.org/#timelapse/.


Timelapse is an interactive video that allows user to pan and zoom anywhere on Earth and view annual mosaics from 1984 to 2012 of historic Landsat imagery. One feature of the viewer is that users can create custom views of their own areas of interest. The easiest way to do this is to zoom and pan to a particular view, and then click the "Share this view" button, which presents you with a custom URL that you can send to anyone. Alternatively, a user can construct URLs by inserting the appropriate latitude, longitude, and zoom level.

Some Timelapse examples for Indiana:

OrbView-3 satellite images collected around the world between 2003 and 2007 by Orbital Imaging Corporation (now GeoEye) at up to one-meter resolution can now be downloaded at no cost through USGS EarthExplorer.

"This is a significant addition to the USGS archive and a valuable resource for the global science community," said Matthew Larsen, Associate Director, Climate and Land Use Change. "Free access through the USGS archive amplifies the utility of the data, making it feasible for many researchers to study large areas at this level of accuracy."

"Partnering with GeoEye brings forward an important commercial resource in response to the need for authoritative, information-rich data about the land surface of the planet," said Bruce Quirk, USGS Land Remote Sensing Program manager.

The OrbView-3 dataset includes 180,000 scenes of one meter resolution panchromatic, black and white, and four meter resolution multi-spectral (color and infrared) data, providing high resolution data useful for a wide range of science applications.

"The Land Cover Office of the Netherlands is already using this OrbView-3 data as a critical input to developing a global land cover data file," Quirk continued. "In addition, the high resolution of this data permits validation of land cover categories produced by moderate resolution data."

The initial data format available is GeoEye's Basic Enhanced (L1B) product. However, processing to a systematically terrain corrected (L1Gst) product is also available on demand. Eventually, the entire data set will be processed to the L1Gst level.

The OrbView-3 dataset joins over 170 separate collections of aerial photography and space-based data cataloged in the National Satellite Land Remote Sensing Data Archive and available through USGS EarthExplorer.

Considered a treasure trove of American history sought after by genealogists, urban planners, sociologists and a gamut of other researchers, Sanborn Fire Insurance maps, first created beginning in 1867 for assessing fire insurance liability for buildings in U.S. cities, are now available to the public for more than 300 locations in Indiana.

The Sanborn Company designated Indiana University's Herman B Wells Library Map Collections as the repository for the original Indiana Sanborn paper maps which the company produced between 1883 and 1966. A recent joint project between IU and Historical Information Gatherers Inc. now provides digital color versions of the maps to the Indiana Spatial Data Portal (ISDP).

"Indiana's historic Sanborn Maps provide an enormous amount of information regarding the growth of our cities and towns," said Anna Radue, an IU database and geographic information systems (GIS) specialist who is also president of the Indiana Geographic Information Council, the coordinating body for GIS in Indiana. "The maps include the outlines of buildings, the location of windows and doors, street names and property boundaries, and even the building materials used for framing, flooring and roofing materials. Genealogists, planners, demographers and the general public will find these maps invaluable for visualizing our past urban areas and understanding our present."

A 2011 grant from IndianaView funded the digital archiving of the 10,020 public-domain maps and 1,497 copyright-restricted maps that represent 305 different Indiana locations. The ISDP provides access to more than 20 terabytes of Indiana geospatial data and most datasets are available to the public for download with no use restrictions. IU's high-performance networks and computing infrastructure support the ISDP, which archives and provides Web access to imagery provided by data partners within and outside IU.

Sanborn maps offer researchers and the public detailed information regarding town and building information in approximately 12,000 U.S. towns and cities from 1867 to 1970. Rich in historical data, each collection includes a decorative title page, an index of streets and addresses, a 'specials' index with the names of churches, schools, businesses, and a master index indicating the entirety of the mapped area and the sheet numbers for each large-scale map.

Other general information includes population, prevailing wind direction, outlines of each building and outbuilding, street and sidewalk widths, fire walls, natural features like rivers and canals, railroad corridors, building use, house and block number, the strength of the local fire department, indications of sprinkler systems, locations of fire hydrants, location of water and gas mains and even the names of most public buildings, churches and companies.

Shaun Scholer, GIS coordinator for Richmond, Ind., and Wayne County, said local government was interested in using the digital maps to assist in community projects. Scholer noted, "Through the use of the 1909 Sanborn maps, Wayne County/City of Richmond GIS Interlocal was able to identify early factory and home site foundations. We have also helped a local urban archeologist excavate old home sites."

When Richmond constructed their new jail, they referred to the Sanborn maps to understand the old foundations they excavated.
"I appreciate your help and access to the files," he said. "We have been trying to figure out ways to get access to them for years."

IU Bloomington Libraries serves as the repository for Indiana maps and holds the rights to make the pre-1924 maps available to the public. They are available (here). Black-and-white versions from the Digital Sanborn Fire Insurance database that are licensed for use by IU students and faculty can also be found (here).

After 1910, Sanborn used what IU Libraries' Lou Malcomb called "paste-overs" to record changes in the maps.

"So these are quite fragile but may be viewed at the Herman B Wells Library," she said. "And more information about the pre- and post-1924 maps may be obtained by contacting the IUB Map Collection (here)."

The Sanborn maps announcement comes in advance of "GIS Day at Indiana University" to be held from 10 a.m. to 3:30 p.m. Nov. 16, at Herman B Wells Library. The event is open to the public and will include information booths, geocaching activities and a 4 p.m. keynote address by Katy Börner, the Victor H. Yngve Professor of Information Science in the IU School of Library and Information Science. Guests will also be able to speak with IU Libraries staff about the Sanborn maps.

The grant provider, IndianaView, is a consortium that includes IU, IU South Bend, Indiana University-Purdue University Indianapolis, Ball State University, Indiana State University, Martin University, Purdue University, Purdue University Calumet, University of Notre Dame, Vincennes University, the Consortium of Universities for Spatial Information Science, Indiana Geological Survey, Indiana SpaceGrant Consortium and the Indiana Geographic Information Council. The purpose of the consortium is to promote sharing and use of public-domain, remotely-sensed image data (aerial and satellite platforms) for education, research and outreach across universities, colleges, K-12 educators and state and local governments.

I have posted some new Landsat scenes from May 3, 2011. These scenes follow the Wabash River. Interestingly, there are clouds in the scenes but most of the flooding is in the area that is essentially cloud free. These images can be downloaded here:

An overview of the Landsat scene covering the Lafayette Area is shown below:


You can clearly see the extent of the flooding from this zoomed in view below:


To view an image which high lights the flooding, I use channels 6, 4 and 3 as red, green and blue. I also used a gaussian stretch for the data (as apposed to a linear stretch that I usually use) because of the clouds in the scene.

On April 07, 2011, the IndianaMap Atlas was updated.
The four layers that provide county-based framework data (including address points, street centerlines, land parcels, and governmental boundaries) have been updated. The layers were compiled from data maintained by various county agencies in Indiana, as part of the IndianaMap Data Sharing Initiative between Indiana Geographic Information Council (IGIC), Indiana Office of Technology (IOT), Indiana Geographic Information Office (GIO), Indiana Department of Homeland Security (IDHS), Indiana Geological Survey (IGS) and participating Indiana counties. The layers named Address Points (IDHS) and Street Centerlines (IDHS) can be found in the following folder: INFRASTRUCTURE > Roads. The layers named Land Parcels (IDHS) and Government Boundaries (IDHS) can be found in the following folder: DEMOGRAPHICS > Political & Other Boundaries.

NOTE: All four layers are also NOW AVAILABLE FOR DOWNLOAD in ESRI File Geodatabase format.

On April 04, 2011, New layers available for download
Although they are not available for viewing on IndianaMap, ten new geologic layers are now available for download from the Geology download page, in a section titled "Indiana Contributions to the National Geothermal Data System." http://inmap.indiana.edu/dload_page/geology.html

Eight of the new layers show geologic structure on bedrock stratigraphic units. These georeferenced IMG images show the elevation (feet above sea level) of the tops of the New Albany Shale (Devonian and Mississippian), the Silurian System, the Trenton Limestone (Ordovician), the Maquoketa Group (Ordovician), the Knox Dolomite (Cambro-Ordovician), the Mt. Simon Sandstone (Cambrian), and the Precambrian basement, as well as the base of the New Albany Shale. They were produced by scanning and georeferencing published paper maps, including U.S. Department of Energy Maps 800, 801, 811, 812, 813, and 814. The other two layers show the elevations of the first occurrences of the 3,000 and 10,000 PPM (parts per million) total dissolved solids boundaries. These TIF images were produced by scanning and georeferencing Plates 1 and 2 of Indiana Geological Survey Open-File Report 94-2.
