Free Book On Emotional Cartography

From Christian Nold’s Biomapping website:

People re-explore their local area by walking the neighbourhood with the device and on their return a map is created which visualises points of high and low arousal. By interpreting and annotating this data, communal emotion maps are constructed that are packed full of personal observations which show the areas that people feel strongly about and truly visualise the social space of a community.

Sample maps in different formats are available online for locations like Westminster, San Francisco and Greenwich:

And a new book called Emotional Cartography: Technologies Of The Self has just been released; a full copy is available in PDF format under the Creative Commons license.

Paging Geographers And Geologists Named George Or Geoffrey

According to the study, “Why Susie Sells Seashells By The Seashore: Implicit Egotism and Major Life Decisions“:

“…no matter how we analyzed these data, we found that people whose first names begin with G, Ge, or Geo gravitated toward the geosciences.”

And they found that people named Dennis were more likely to become dentists.

Marine Navigation GIS Data

SM asks if I know “any free or commercial data source for boat landing or (boat ramp) sites…? I am especially interested in IL,IN,OH,and MI area.”.  My first idea was to check two US Government sources of marine GIS map data.

Even More Mac GIS Software For Free

Thought I was done with adding new Mac GIS apps to the full list, but here’s a few more:

CoastWatch - “The CoastWatch Software Library and Utilities is a package of software tools for working with earth data sets distributed by the NOAA/NESDIS CoastWatch program.”

GeoJasper – Converter between GeoTiff and GeoJPEG2000.

Geomajas – “… an open source, web-based GIS framework specialized in editing and complex attribute relations.” Apparently works with Firefox in Mac, but has issues in Safari.

GeoMapApp: “GeoMapApp provides direct access to the Global Multi-Resolution Topography (GMRT) compilation that includes high resolution (~100 m node spacing) topography from multibeam data for ocean areas and Shuttle Radar Topography Mission (SRTM) data over land.”

GeoVISTA Studio – “GeoVISTA Studio is an open software development environment designed for geospatial data. Studio is a programming-free environment that allows users to quickly build applications for geocomputation and geographic visualization.” Note: Seems to have issues with the most recent versions of Java, at least on my PC.

Minerva -”Minerva is an open-source program for viewing geospatial data that works on Windows, Mac, and Linux. It unifies standard GIS capabilities with high-performance, 3D visualization”

MSphinx - MODIS Satellite Process Handling Images uNder Xwindow.

SeaDAS - “ The SeaWiFS Data Analysis System (SeaDAS) is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data.

SGeMS – “SGeMS is a software for 3D geostatistical modeling.” Source code only is provided; website says that you should be able to compile it for Mac OS X, but apparently no one has tried it yet, and no Mac binaries are available.

STARS – “Space-Time Analysis Of Regional Systems (STARS) is an open source package designed for the analysis of areal data measured over time. STARS brings together a number of recently developed methods of space-time analysis into a user-friendly graphical environment offering an array of dynamically linked graphical views.”

StarSpan“StarSpan is designed to bridge the raster and vector worlds of spatial analysis using fast algorithms for pixel level extraction from geometry features (points, lines, polygons). StarSpan generates databases of extracted pixel values (from one or a set of raster images), fused with the database attributes from the vector files.”

VAPOR - Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers.

  • A visual data discovery environment tailored towards the specialized needs of the geosciences CFD community
  • A desktop solution capable of handling terascale size data sets
  • Advanced interactive 3D visualization tightly coupled with quantitative data analysis
  • Support for multi-variate, time-varying data
  • Close coupling with RSI’s powerful interpretive data language, IDL.
  • Support for 3D visualization of WRF-ARW datasets

WorldWatcher - “WorldWatcher, a supportive scientific visualization environment for geospatial data, is available for both Macintosh and Windows. The software provides an accessible and supportive environment for students to explore, interpret, and analyze scientific data in a manner which allows them to emulate the work of actual scientists.” Note: This appears to be a free, but I can’t tell for sure.

Commercial software (i.e. not free):

MyWorld GIS – “My World GIS™ is a Geographic Information System (GIS) designed specifically for use in educational settings.  My World allows learners to explore and analyze geographic data about our world.”

GAIA - “GAIA (Geographic Access Image and Analysis) Software … capabilities are focused on displaying any earth imagery including full SPOT or LANDSAT images and allowing users to combine spectral classes into meaningful covertypes and analyze a given area for acreage. GAIA also has full rastor/vector integration and can overlay vector maps (from MapGraphix and Microstation) onto the raster imagery to superimpose roads, geopolitical borders, hydrography, etc.”. Note: No download link, original website is down, may no longer be available.

All these will be added to the full list shortly.




More Free Mac GIS Programs

A final roundup of Macintosh GIS progams that I missed in my original post (they’ll be added to that main listing shortly)

R – An open-source statistical analysis package. See this page for references on using it for geospatial analysis.

JGrass – A Java implementation of GRASS with emphasis on hydrological and geomorphological analysis; uses uDIG as a framework.

KyngChaos - Mentioned by several commenters; a source of Mac OS X builds of GIS-related software like GDAL/OGR and MapServer.

OSSIM:

OSSIM provides advanced geo-spatial image processing for remote sensing, photogrammetry, and Geographic Information Systems.  Backed by an active open source software development community, OSSIM solutions have been deployed on a number of critical commercial and government systems.

And going back to my listing of aerial/satellite imagery programs, which included OSSIM:

One – A through H
Two – I through M
Three – N through R
Four – S through Z
Five – GIS software

I found:

HEG – “… a tool developed to allow a user to reformat, re-project and perform stitching/mosaicing and subsetting operations on HDF-EOS objects. The output GeoTIFF file is ingestible into commonly used GIS applications. HEG will also write to HDF-EOS Grid & SWATH formats (i.e for Subsetting purposes) and native (or raw) binary. HEG presently works with MODIS (AQUA and TERRA), ASTER, MISR, AIRS, and AMSR-E HDF-EOS data sets.”

Comments and emails also referenced paid Mac GIS-related software:

Avenza - Add-ons like MAPublisher and Geographic Imager for Photoshop and Illustrator

Ortelius - Mapmaking software (coming soon).

TNTMips - Full version of the freeware TNTlite.




Two IP Mapping Utilities

Two online applications for mapping IP addresses:

IP-Locator:  Plots the location of your current IP address, gives the approximate coordinates and elevation, with the option to export it as a KML file.

You can also type in an IP address, and get its geographic location plotted as well, with KML export. But for more than one IP address, and multiple export formats, there’s ….

IP-Mapper: – Enter a list of IP addresses in the box at left:

4-8-2009-9.01.43 PM

Click on Geocode, and get back the position(s) of the IP addresses plotted on a world map, along with the option to export the data in KML, CSV, DXF, shapefile, Tab-delimited or plain text formats:

4-8-2009-9.09.53 PM

Two additional notes:

  • If you want to find the numerical IP address for a website, do a Google Search for “domain name lookup” to find dozens of online apps that do just that, e.g. IP Address Lookup.
  • The geographic location derived from a website IP address is for the server hosting the website, which isn’t necessarily where the website content originates. Free Geography Tools’ IP address is 69.89.31.179; plug that in, and you’ll find that the server is located in Orem, Utah, whereas I am in, and plan to stay in, Flagstaff, Arizona.



Google Earth Coordinates In Multiple Projections With Plex.Mark

By default, Google Earth uses latitude/longitude as its coordinate system, with WGS84 as the datum. In the Tools section, you can choose to display lat/long in decimal degrees, degrees/decimal minutes, or degrees/minutes/seconds. You can also set the displayed coordinate system to UTM (Universal Transverse Mercator)/WGS84, a coordinate system often used on maps. But for other coordinate systems and datums in Google Earth, you’re out of luck.

Plex.Mark is a small helper app for Google Earth that, to a limited degree, can show you the position in the center of the Google Earth in many other coordinate systems. After installing and running the program, Google Earth will open up, and the Plex.Mark dashboard will overlay the display, always on top:
