Photopic Sky Survey

SkyServer DR7 Tools for Visual Exploration The visual exploration tools built for the SkyServer make it easy to visualize and explore detailed astronomical data in regions of the sky covered by the Sloan Digital Sky Survey. One can specify regions of interest by central position and size. An underlying web service then combines the relevant images to form a JPEG mosaic* at the requested wide range of resolutions. One can overlay additional useful information, including: boundaries of survey fields and aperture plates, outlines of individual objects and data quality masks, and locations of photometric and spectroscopic objects. The tools can also search for lists of known objects, provide links for detailed information, and formulate new database queries.

Visualizing Databases I’ve become quite the fan of Gephi, lately, and received a good-natured challenge by one of my colleagues, which went something like, “Why is a everything a network with you, now?” Obviously, in the case of social network-like phenomena, such as mapping collaboration in the Digital Humanities with the DH@Stanford graph–network theory and network language (whether visual or theoretical) make sense. Network analytical tools like Gephi are also only a short step away from spatial analytical tools, like ArcGIS, many of which are used to ask questions about geographic networks and not about the kind of continuous data found in topography. Tooling Up for Digital Histories as part of the DH@Stanford graph, which describes collaboration as temporally-aware instances of interconnected social networks at Stanford University.

Sun`s path June to December « Helpmyphysics Last June I placed some photographic film into a tin cannister with a small hole punched into its side. The tin cannister was then attached to a clothes pole in my backgarden and left. This afternoon I fetched the cannister and took the photographic film out.

Image Resources at the NSSDC General Image Services Specialized Image Services Planetary Data Visualization Visual and Technical Arts Laboratory Other NASA Data Archive/Service Centers Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

Earth Time Lapse Video from ISS is Amazing! This time lapse video, taken by the International Space Station, is filled with lightning storms, the Northern Lights, tropical currents and pure awesomeness. The video is a series of sequence photographs taken with a low-light 4K-camera by the crew of Expedition 28 and 29. If you have commitment issues and do not want to watch a five minute video, there are some screen grabs below. But trust me, the lightning storms a lone are worth it. Here is what you are seeing, in order of appearance:

Hubble's Hidden Treasures 2012 Since 1990, Hubble has made more than a million observations. We feature many of these on, and the most stunning are in our Top 100 gallery and iPad app. But there are thousands of pictures in Hubble’s science archive that have only been seen by a few scientists. We call these images Hubble’s hidden treasures — stunning images of astronomical phenomena that have never been seen and enjoyed by the public.

Live map of London Underground trains Loading... Powered by Leaflet — Map tiles © Thunderforest, data © OpenStreetMap contributors. Live London Underground map DaylightMap DaylightMap shows the pattern of night and day on a Google map, for any area of the Earth, for any date and time. The night-side satellite view includes city lights as seen from orbit. It also allows you to select up to ten locations on the map; in addition to seeing at a glance whether it's daytime there, you can show their local time, sunrise and and sunset times, and length of day. These locations can be remembered for future visits, saved as a bookmark, or sent to other people as a web link. This site can thus function as a graphical world clock, and can be used to show relative times of any future or past event. This particular DaylightMap is highlighting times for .

NASA's Planetary Photojournal Weave Data Tutorial Weave Data TutorialTutorial for Weave Magazine 03.10 about visualizing network data Client: Weave Magazine / Page publisher We all use twitter, write emails, skype and blog all day long. logTool: Revealing the Hidden Patterns of Online Surfing Behavior logTool [] is a data visualization tool that displays your online activity, based on data from the powerful network packet sniffing tool Carnivore. By analyzing the different IP addresses and ports, the visualization is able to determine and represent what kind of application or service sends or receives the packets. Developed for the magazine Weave, logTool was used to digest the surfing behavior of several interaction designers, artists and developers.

Creating a visual “fingerprint” for film - thesis project by Frederic Brodbeck #processing Cinemetrics is the thesis project of Frederic Brodbeck‘s at the Royal Academy of Arts (KABK), Den Haag. It aims to create a visual “fingerprint” for film using the editing structure, color, speech and motion. Different characteristics are analysed using python and openCV, and data visualised using a custom Processing application. This allows films to be interpreted or compared side by side. Being someone who really enjoys movies and cinema, I always notice little things about the style of a movie, so film and its characteristics were an interesting starting point for this project. Furthermore my thesis is about generative / computational design and what role writing code plays regarding new approaches in (graphic) design.
