ArcGIS Earth

When I visited university (I have t admit, this was some years ago 😉 ) I was told ArcGIS cannot “do” 3D. This was the part where CAD enters the arena… But time goes by and together with ArcGIS 10.4. we will get 3D as it is meant to be.

Google Earth Pro is now for free!

Google recently made an announcement that left me very happy: Google Earth Pro, the enhanced version of the world’s most popular digital globe, is now available for free. The software comes with some additional features compared to classical GoogleEarth and used to be $400 per year – actually many users paid because the benefit was huge. Now all you have to do is to register, get a free key, and download the software. If registration doesn’t work for you, don’t worry and don’t give up. It didn’t work for me when I tried first, the next day I tried again…

Skybox Acquired by Google

So I have been hearing rumors for a few weeks now that Google is trying to close a deal to buy Skybox Imaging (TechCrunch, May 23, 2014) and from the Skybox blog it seems that this day has finally come (Skybox Imaging + Google). If you are not familiar with Skybox Imaging, they builds and launches cost efficient satellite that captures sub-meter 1080p HD resolution video (at 30 frames per second) for up to 90 seconds (link here for more information).  Beside being a really cool use of imaging satellites (video here), this is a very strong acquisition by Google for a…

geocoding addresses directly in LibreOffice Calc

In a recent post I’ve described a way to geocode in a Google Spreadsheet quite easily. Now let’s move a little bit away from this crazy web 2.0 stuff and get a little bit more desktop orientated: Let us geocode addresses directly in LibreOffice (and OpenOffice probably as well). We will do this using the googlemaps API. If you are really into open stuff we show OSM geocoding as well.

short announcement: The Mercator Puzzle

A lot of articles here at Digital Geography deal with maps and projections. You may have wondered how wrong the different map projections are or let’s say, what they lead us to think how big some areas on earth might be. Well, I can not tell you exactly, but the Mercator Puzzle gives you an idea on the errors that we need to deal with. Plus, it’s fun. Drag the outlines and fit them to countries: The Mercator Puzzle by Google. (To be honest, I expected myself to perform better…)

Google Earth Engine – free spatial data- and analyse-workspace

Google’s Earth Engine offers spatial researcher-tools in combination with their huge amount of collected satellite data. In fact you have the possibility to access e.g. 40 years of LANDSAT-data (of course for free) and show it in your browser-worspace. But this is just the beginning. Explore detection of deforestation, landcover classification, biomass and carbon estimates and much more.

short announcement: Earth Engine by Google

On the 9th of May Google introduced an astonishing new technology that makes the good old flickr function in Erdas Imagine quite useless. With the Earth Engine from Google Earth you will be able to see the world change since 1984. They have compiled about 900 terabyte of Landsat Data. So they stitched, balanced the contrast, analysed and ordered about 2’000’000 images of the world to provide a comprehensive look into Earth’ history: Erdenet (Mongolia): coal mining lake Ugii Nuur (Mongolia): drying and dying Jänschwalde (Germany): coal mining Las Vegas (USA): urban sprawl Additionally you are able to browse the…
