Check out this great blog post in American Scientific that discusses data integrity, datums, projections, data relevancy (as its related to time). http://blogs.scientificamerican.com/critical-opalescence/2013/11/11/what-happens-to-google-maps-when-tectonic-plates-move/?WT.mc_id=SA_emailfriend the fall issue of Esri News for Students and Recent Graduates is now available online: http://www.esri.com/careers/students/career-newsletter Included in this issue:
"The U.S. Geological (USGS) and other scientific institutions are using social media and crowdsourcing to learn more about earthquakes, according to a new report. These techniques provide inexpensive and rapid data to augment and extend the capabilities provided by traditional monitoring techniques" To continue reading: http://wilsoncommonslab.org/2013/07/10/report-looks-at-successful-government-crowdsourcing-efforts-for-earthquake-monitoring/_ Here is an interesting post written by Joseph Kerski on spatial data after the ESRI User Conference this past July. http://spatialreserves.wordpress.com/2013/07/22/reflections-on-spatial-data-from-the-2013-esri-international-user-conference/ http://www.lincolninst.edu/pubs/2072_Atlas-of-Urban-Expansion Atlas of Urban Expansion The main objective of this Atlas of Urban Expansion is to increase understanding and help residents, policy makers, and researchers around the world come to terms with the expected global urban expansion in the coming decades. The Atlas in book form introduces the project and presents two sets of full-color maps and a set of raw data tables. The first map section contains pairs of urban land cover maps from circa 1990 and 2000, representing a global sample of 120 cities. The second map section includes composite maps of a global representative sample of 30 cities, showing the historical expansion of their urbanized areas from 1800 to 2000. In both sections, the maps shown are paired with numerical and graphical data, making it possible to compare cities in terms of their metric values on key attributes of urban expansion. The third section contains four extensive tables of urban, national, and regional data for each of the 120 cities. Data and images from the Atlas of Urban Expansion are available for download on the companion website, http://www.lincolninst.edu/subcenters/atlas-urban-expansion/ http://www.lincolninst.edu/subcenters/atlas-urban-expansion/gis-data.aspx Section 4: Geographic Information System (GIS) Data for Cities The GIS data used in the analysis and in making the maps can be downloaded from the website. GIS software, such as ArcGIS, is required to view these data. For each city in the 120 city sample, these data include: 1.two urban land cover maps, one circa 1990 and one circa 2000; 2.the administrative boundary shapefile; 3.two maps of the urban landscape categories, one circa 1990 and one circa 2000; 4.the map of new development categories (infill, extension, leapfrog). For each city in the 30 city historical sample, these data include the urbanized area shapefiles for each time period. Use of data should include the following citation: Angel, S., J. Parent, D. L.

A new book of 75 personal maps of Manhattan is just the latest in a new wave of cartographic creations by artists – both famous and amateur – seeking to put the romance back into this centuries-old art form.

An interesting read!
