GIS Issue of Library Trends

Guess what: Library Trends v.55 no.2 is devoted to Geographic Information Systems and Libraries. Yep, the entire issue. Articles I am most eager to read:


Libraries as Distributors of Geospatial Data: Data Management Policies as Tools for Managing Partnerships
G. Steinhart
Library Trends 

Libraries can bring substantial expertise to bear on the collection, curation, and distribution of digital geospatial information, making them trusted and competent partners for organizations that wish to distribute geospatial data. By developing a well-thought-out data management and distribution policy, libraries can define the parameters of a data distribution partnership and reinforce a data provider’s confidence in the library’s role as a data custodian and distributor. In developing a policy, data distributors are advised to consider such issues as intellectual property rights, liability issues, distribution methods and services, data and metadata management practices, security risks posed by geospatial data, and user limitations. This article describes the most common elements of data sharing and distribution agreements and describes the development of a data management policy for the Cornell University Geospatial Information Repository (CUGIR).

Geospatial Web Services and Geoarchiving: New Opportunities and Challenges in Geographic Information Service
S. P. Morris
Library Trends 

Over the course of the past fifteen years the role of Geographic Information Systems (GIS) has changed significantly. Initially the role of the map library was confined to that of building and providing access to collections of hard copy maps and imagery. Later, digital data, whether on CD-ROMs or network based, was added as a new type of resource within that collection and service model. By the late 1990s some academic libraries began to take on a Web map server role, providing interactive Web mapping access to collections of digital geospatial data. In the new era of distributed, interoperable map services, libraries will have an opportunity to explore new roles as portals to streaming content available in the form of geospatial Web services. At the same time, the increasingly ephemeral nature of digital geospatial content will make even more critical the need to address the long-term digital preservation challenges that are facing geospatial content.

Digital Preservation of Geospatial Data
M. L. E. T. Sweetkind, Julie; Larsgaard
Library Trends 

The selection, acquisition, and management of digital data are now part and parcel of the work librarians handle on a day-to-day basis. While much thought goes into this work, little consideration may be given to the long-term preservation of the collected data. Digital data cannot be retained for the future in the same way paper-based materials have traditionally been handled. Specific issues arise when archiving digital data and especially geospatial data. This article will discuss some of those issues, including data versioning, file size, proprietary data formats, copyright, and the complexity of file formats. Collection development topics, including what to collect and why, will also be explored. The work underlying this article is being done as part of an award from the Library of Congress’s National Digital Information Infrastructure and Preservation Program (NDIIPP).

Building a Library GIS Service from the Ground Up
R. Houser
Library Trends 

Geographic Information Systems (GIS) services in academic libraries tend to differ, based on availability of GIS data, software, hardware, and staff expertise. GIS services at the University of Kansas are closely aligned with support for government information, data, maps, and statistics. Thus, our responses to users’ needs are often naturally collaborative, optimizing the expertise of multiple staff members and various types of resources. The GIS and Data Specialist assists campus researchers with spatial data and software, as well as facilitating access to GIS data. Lab space for research and coursework involving spatial data is a core component of GIS services. In addition, various levels and types of GIS workshops are offered each semester, and custom training sessions are also available. “Word of mouth” and hands-on workshops are some of the most effective methods of outreach.

Centralized vs. Decentralized Systems: Academic Library Models for GIS and Remote Sensing Activities on Campus
J. Aufmuth
Library Trends 

Academic libraries are a prime example of an enterprise whose mission is to support the information needs of its institution. Geographic Information Systems (GIS) and remote sensing (RS) are popular topics for academic research and are used globally. Two major enterprise information service and data delivery models, centralized and distributed, describe how enterprises approach information sharing. Simply stated, centralized systems provide services and data through a single individual or departmental unit. Distributed systems rely on many interconnected individuals or units to supply services and data. There are advantages and disadvantages to both, which may lead to a hybrid model of combined elements or a movement away from one and toward the other. This article discusses centralized and distributed enterprise information service and data delivery models and how two Florida university libraries deploy these models to deliver enterprise GIS services and data to their institutions’ user communities.

Turns out that’s just about all of them, but it’s not often entire editions of a journal — a library journal, no less — is devoted to my specific job. The toc and article URLs can be found here.



More Love for the MacBook

Well, first here’s the most recent Rumsfeldian metric: another in my line of running tallies of unread RSS articles is the following (a new record):


That’s right: I got so far behind this last week that I had over 7,000 articles waiting for me. Hm. Groan. Eh, if you’re not busy you’re not doing enough, perhaps.

Another thing waiting for me was VerySpatial’s Part 1 of a series on GIS on Macs. Naturally, I haven’t watched/listened yet.


It’s True and It’s Awesome (ArcGIS on OS X).

Mostly. Quickly, I have to register this news about my new ability to run ArcGIS 9.2 from within my nice, easy, powerful, beautiful OS X. The Intel Macs can do it either through Boot Camp (maybe this weekend) or via Parallels. The Parallels version now offers (in beta) an operating mode called “Cohesion” that makes it seem very much like you’re running OS X and XP apps (ArcGIS 9.2, though, which is another story) right next to each other. It works and it’s fast.


Edit for the coolest part yet (Cohesion works with Expose):



Indiana Bolsters Google Earth

Filed under: Data Sources, Geographic Exploration Systems, GES, Uncategorized — geoLibro @ 7:22 pm

It looks like the hint Senator David Ford let out at IU’s GIS Day keynote is true: Google Earth has been updated with very high-resolution imagery that looks to be courtesy of the Indiana State government. And all of those rural areas whose states haven’t provided Google Earth with high-res coverage are just going to have to groove on that.
