While Google Earth is still around, it makes sense to maximise its usefulness. The Google Earth Blog shares some nice pointers how to tune your GEarth installation in case you experience performance issues. They’ve also recently covered a company called KMZmaps.com which offers a set of custom KMZ overlays for use in GEarth. Honestly, I … Continue reading Some GEarth tips
Crowdsourcing projects like OpenStreetMap, Google Map Maker or Building Maker without compensation for contributors rely on volunteers’ efforts. There are various studies which try to shed light on the motivational factors of such volunteers. One way to motivate people to contribute their time and effort can be to make them feel that they are part of … Continue reading Motivating volunteers
Maps are about territory. And in history, cartography has often been (ab)used to political ends. Due to its big popularity and global visibility Google’s geo-products have attracted their share of border and naming debates and disputes over time and the change of a border’s status or the name of a proportion of land in, for … Continue reading Google in Libya
A while ago I reported on a collection of historic maps of undersea cables. In today’s post I’d like to highlight an interactive and up-to-date version of such a map: For every undersea cable, Greg’s Cable Map by Greg Mahlknecht shows characteristics such as a list of landings of said cable, bandwith, length, construction date and … Continue reading World’s wiring scheme in an interactive map
Hot from the press: Esri announces the acquisition of Procedural. The Switzerland-based company specialises in procedurally (i.e., rule-based) constructed 3D city models and is known, for example, for its reconstruction of ancient Rome. Procedural’s approach, embodied in its software CityEngine, allows for very fast modelling of urban scenes.
Esri’s move will considerably strengthen its stand in the 3D realm and maybe we will at some point see BIM (Building Information Modelling) by Esri? Spatial Sustain points out correctly that Esri hasn’t usually grown by acquisitions, but steadily by its own activities. Before that background, Esri’s move into 3D via Procedural seems rather outstanding and meaningful!
Head past the break for some rather captivating examples of Procedural’s products. Continue reading “Esri buys Procedural”
Infoworld has a run-down of nine IDEs for Python development. Unfortunately, to access the full text one has to register (for free), but if you are looking for ways to streamline your Python coding, it’s worth the hassle. Continue reading Comparison of Python IDEs
Yay, my hope’s coming true, apparently the new visual style of Google+ is contagious within the Google realm. Both GMail and Google Calendar will feature de-cluttered GUIs. In Gmail they are already accessible as themes (called Preview and Preview (dense)), GCal will follow soon. (via Engadget and GMail Blog) Continue reading New visual styles in Google products
Till Nagel has a tutorial on using custom maps as backgrounds in Processing sketches. The solution uses TileMill, a map design environment which allows you to export a customised static map as an image for use in Processing. For advanced users, Till Nagel also describes the procedure for interactive tiled maps. That latter solution relies on an … Continue reading Using customised basemaps in Processing
In order to present readable and usable code here on WordPress.com without manually formatting it I searched the intertubes for an elegant solution – and found one here. [sourcecode language=”python” gutter=”false”] import math, string def readFile(file): """Reads a file from disk and returns its content as a string variable :param file: path to a file to be … Continue reading Syntax highlighting on WordPress.com
Boing Boing highlights this map of undersea cables of the Eastern Telegraph Company system printed in 1901. At Boing Boing’s source a person points to a treasure trove for anybody interested in the history of undersea cables or, specifically, related cartography. Above map with its salient red cables clearly highlights the Europe- and US-centric history of … Continue reading Old maps of undersea cables
Living in Switzerland you don’t get to experience many weather phenomena as dramatic as hurricanes and tornados. However, a former colleague of mine investigates the movement patterns of hurricanes to find similarities between individual storms. And in 2004, I was professionally dealing with hurricane Ivan. Ivan was a Category 5 hurricane and is, apparently, the 10th most intense Atlantic hurricane ever recorded. Back then we ordered a Quickbird image (and were lucky enough to get one without too much cloud coverage) and did both a qualitative and quantitative damage assessment of Grand Cayman Island.
These have so far been my only exposures to the study of extreme weather events and, specifically, to the analysis of storm-induced damage captured by means of remote sensing. But some days ago NASA’s Earth Observatory has released a stunning image of a tornado track (of one of the several tornados which have struck Massachusetts in early June 2011) that is well visible from space. Head past the break for the image and more info.
