Mapping Science Committee of the National Research Council has released its report "National Land Parcel Data: A Vision for the Future" available (including free download of Report in Brief) at
http://www.nap.edu/catalog.php?record_id=11978.
Private ownership of land is a foundation of the financial, legal, and real estate systems of our society. Furthermore, open access to information about ownership and use of land has always been a cornerstone of our democracy and free enterprise system. In a modern land information system, land parcel databases describe a combination of the rights, interests, ownership, and value of property. Parcel data (also known as cadastral data) constitute the most appropriate level of geographic detail for a host of decisions and actions relating to the development of land, business activities, regulatory compliance, emergency response, law enforcement, and logistical support. Parcel data are also critical to the analysis of natural hazard risk, transportation needs, and even environmental issues.
While a great deal of parcel data has been digitized at the local level, 30 percent of individual parcels still need to be converted, and there has been little progress toward an integrated national set. Many of the technical barriers have been overcome, so the remaining challenges are primarily organizational. The committee makes nine recommendations for over- coming these remaining barriers.

This is the newsletter for the Indiana GIS Atlas monthly update for November 2007.
Several important enhancements of the Indiana GIS Atlas were implemented on Tuesday, November 27.
New Layers
Three new layers have been added to the interactive map. The new layers show crops grown in 2006 (US Department of Agriculture), cultivated areas for 2004 (US Department of Agriculture), and electric service territories (Indiana Utility Regulatory Commission, IURC). In the electric service territories layer, the boundaries shown are strictly a visual aide and a best interpretation of the legally approved territories, as ruled by the IURC. These data are not legally binding or necessarily fully representative of the legal rulings.
On-line User Surveys
On October 29, we solicited users to complete a survey to help us assess the usefulness of the GIS Atlas. To date, we have received a total of 68 responses. Below are the current results of the ongoing survey:
57 percent of respondents use the GIS Atlas daily or weekly
94 percent use the Atlas for job-related tasks
Organizations that use the Atlas include consulting companies (38 percent) and governmental agencies (27 percent)
80 percent of respondents do not consider themselves to be GIS professionals
82 percent have high-speed internet connections
50 percent use the metadata
60 percent have downloaded data
The most commonly used tools include “Measure Distance/Area,” “Identify,” “Zoom to Location,” and “Save Map as JPEG”
26 percent of respondents have used the video tutorials
97 percent rank their overall experience using the GIS Atlas as “satisfied” or “very satisfied”
Most used layer: 2005 aerial photography
Most requested layers: historical aerial photos and parcel boundaries
If you have not yet participated in the survey, please take a few minutes to complete the user survey http://www.surveymonkey.com/s.aspx?sm=21baQOTpK9W0eoYvyj5zMA_3d_3d , which includes only 16 questions. Your input will guide us in future development of the GIS Atlas.
We have received a total of 30 responses to our previous survey (posted on September 21) regarding a recent computer-server upgrade and its effect on the speed and performance of the GIS Atlas. Sixteen (16) users indicated that speed and performance have improved, while fourteen (14) indicated that they have noticed no change.

You can now download the NHD as a file-based geodatabase. File sizes are about one-third of personal geodatabase file sizes. For example, subbasin 13010004 produces a 27.0 MB high resolution personal geodatabase, but a 10.5 MB file-based geodatabase. After selecting and downloading the file you need to unzip it. Unzipping it results in a folder full of many files rather than the familiar single .mdb file produced by personal geodatabases. Many users like to rename the downloaded file to a more meaningful file name. If this is done, do it in ArcCatolog rather then Windows Explore to prevent corrupting the file structure. To the user, file-based geodatabases work exactly the same as personal geodatabases in ArcMap, ArcCatalog, and ArcToolbox.
