Python Scripting for ArcGIS
Python Scripting for ArcGIS is a new text from Esri Press by Paul A. Zandbergen (2013). It isn’t the first Python book for the geospatial community or even focused on ArcGIS, but it is the first that has the Esri logo on it. Much like other recent books on Geo/Python we have seen, it focuses on integrating an introduction to Python with the industry specific materials. As Frank mentioned when he highlighted the book in a previous podcast, this allows users to gain exposure to Python, but it doesn’t fall back on the (in my opinion) bad habit of most programming texts of spending half of the book on the language and concepts before even getting to the application in the specific area. There is a time and place for that approach in Python specific books. When you add another software library to a book, then use it from the get go.

Federal Government GIS and Geospatial Conference 2013
OpenGeo is going to sponsor FedGeo Day 2013 at Washington DC on Feb 28, 2013. The
theme of the conference is about Modern Tools for GIS, Geo Data & Cartography,
which will introduce you to GIS, cartography, web mapping, and map publishing
tools, show you what you can do with them, and walk through how and why
government agencies are using them to dramatically improve their mapping,
cartography, and GIS projects.
The conference announcement from their newsletter...
OpenGeo
is proud to support FedGeo Day, the exciting new conference in Washington
DC. The event offers a platform for those who work in or with federal agencies
to share their experiences with modern open source geospatial technologies.
We’re
looking forward to seeing case studies of how these tools are being used in
government, what benefits they bring, and why so many agencies are shifting to
open source technology. There will also be interactive demos that explore
specific open source tools and applications. The schedule
is packed with programming that should be particularly attractive for those for
those who make technology decisions within the federal government.

Watch Online NASA Launching New Satellite: LDCM/Landsat 8
Today, February 11, the next Landsat (LDCM/Landsat 8 http://ldcm.nasa.gov) will be launched from Vandenberg Air Force Base at 1802-1850 GMT .
If you are interested in watching it will be streamed on NASA Internet TV (see http://www.nasa.gov/multimedia/nasatv/schedule.html). Also see at http://www.spaceflightnow.com/tracking/ for space flights information.
The launch of LDCM is scheduled for just over 90 minutes.Click the following link to watch NASA HD stream of LDCM launch.
If you are interested in watching it will be streamed on NASA Internet TV (see http://www.nasa.gov/multimedia/nasatv/schedule.html). Also see at http://www.spaceflightnow.com/tracking/ for space flights information.
“The data from Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. With the launch of the LDCM on Monday, February 11, the record will be continued and enhanced, providing data intrinsic to our geographic and Earth system science research. Since 1972,

Interactive Map of Freshwater Species
"Freshwater Ecoregions of the World, (FEOW) provides a new global bio-geographic regionalization of the Earth's freshwater biodiversity. Covering virtually all freshwater habitats on Earth, this first-ever ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts, particularly to identify outstanding and imperiled freshwater systems; for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy."
"Over a decade of work and contributions by more than 200 leading conservation scientists have produced a first-ever comprehensive map and database of the diversity of life in the world’s freshwater ecosystems. The map and associated fish data – a collaborative project between World Wildlife Fund and The Nature Conservancy."
For the fish lovers, the map is so cool. Since you all like fish....you might find it just as cool too!!! It is interactive, click on an ecoregion, it shows threats, species etc. User is able to change transparency on the image to show terrain behind the ecoregion.
Oh yeah, there is a complete article that went along with it...

Interactive Map: Looking Earth from Moon and Sun
Earth
and Moon Viewer, an
Impressive site which shows orthographic views of the Earth and the Moon using
a mosaic of various satellite imagery including a full-color image of the Earth by day and night, a topographical map of the Earth, up-to-date weather satellite imagery, or a composite image of cloud cover superimposed on a map of the
Earth, a color composite which shows clouds, land and sea temperatures,
and ice, or the global distribution of water vapor. You can view either a map of the Earth showing the day and night regions at this
moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet
specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around
the globe.

Geospatial data Mashups with Google
Abstract
Analyzing space-time variation is common in Geography. Appropriate geo-spatial visualization enables us to understand data in a precise manner. There have been numerous researches, tools, and methods in pursuit of a better visualization method for geospatial data. Here we present the sets of examples developed by us to show the benefits of the web cartography using Google Earth/Google Maps mashups to display geospatial data. Moreover, we include the practical implication of applications that are useful for visualizing geospatial world.

Automated Tools for Integrating Remote Sensing Data Into Spatial Epidemiology Research
Satellite remote sensing provides valuable information that can be used to map infectious diseases and forecast future health risks. However, amassing and managing the geographic information from diverse datasets is difficult and time-consuming. Therefore, there is a need for a geoinformatics system that integrates the acquisition, processing, management, and analysis of geospatial data sets from various sources.
Here, we present our software model for automated data capture and processing of satellite remote sensing data for public health applications. The system incorporates land surface temperature and vegetation indices from MODIS precipitation data from TRMM, and a novel measurement of actual evapotranspiration.
