Is Greenland actually bigger than Africa or Australia? This question is common when looking at the most popular online maps.
To anyone with a globe, the answer is clear: Of course not. However, why, then, does it looks like it is?Read on ...
I love globes, and I was delighted when I found an interview of Peter Bellerby in Fashion Times. Peter Bellerby is the founder of Bellerby & Co., and they are making impressive handmade and hand-painted globes.
Mind you, the globes are very expensive; the cheapest you can buy is £999, and Bellerby are marketing their globes as luxury goods. If the globes are outside your price range, you can still enjoy beautiful photos on their Instagram account.

If you are looking for a new maps design inspiration, this “excited” comic map by Katie Kowalsky is an excellent little gem.
Think Google Maps is the only online mapping tool in town? Think again.
These days, there are a ton of excellent tools for online maps of any flavor. Toptal engineer Tomislav Bacinger breaks down the options, and gives you all you need to know to pick the best tool for your every mapping need.
I’ve written an article for a Toptal Engineering Blog that reviews current online mapping frameworks, compares mapping libraries and services with code examples, and gives a little bit of a mapping history.
Manipulating and presenting geographic data can be tricky. If your destination is beautiful custom web maps, it can be tough to navigate the multitude of tools to get there.
Need directions? Toptal engineer Tomislav Bacinger shows the way, demonstrating how the D3.js library fulfills all your cartographic desires.

Out of my initial future plans list, only the support for additional coordinate systems, namely Gauss–Krüger zone 7, is not realized. Unfortunately, so far I did not get any request for that feature.
At the moment, I am thinking to improve the accuracy of the tool by providing more transformation parameters with the ability to select more precise transformation parameters for specific areas/counties, namely using Transformation parameters per each county in Croatia document.
In the end, many thanks to those who did sent me a bug reports and helped me to resolve them.
I’ve finally got the project where I could try the latest version of the Intergraph GeoSpatial Portal. Here is my short experience with the Portal, and a few problems that I have run into.

Klokan Technologies GmbH, Switzerland announced EPSG.io, a new web service that simplifies discovery of coordinate reference systems. New service includes a database of over 6000 coordinate systems used in maps worldwide, based on the official EPSG database that is maintained by OGP Geomatics Committee.
- It is much easier to find the coordinate systems (for example query “utm wgs norway” gives list of all UTM zones with WGS covering area of Norway).
- All available transformations for selected coordinate reference system are visible and applicable (it is possible to find alternative 7 parameter transformation for Proj4js replacing a default grid transformation, or choose a transformation with higher accuracy for a selected area).
- Preview location for any numerical coordinates on a detailed map - with copy&paste functionality.
- Complete EPSG database with codes for datums, units, transformations, etc is indexed and searchable, and the individual EPSG records are linked from every detail page.
Zurich-based academic and researcher Sergei Lupashin had an idea - to put the quadcopter on a leash. The story behind it is to show that a leash can completely change the nature of a drone and that it eliminates a need for special piloting skills. Lupashin compares a drone on a leash to a kite, and therefore calls it Fotokite.
At the core of the Fotokite approach is the “keep it simple” philosophy. There’s no remote control and there is no GPS unit, just accelerometers and a gyro that measures the speed of rotation. The software on board of the Fotokite takes care of maintaining the same relevant angle to the direction its “pilot” is moving. This allows a steady control over photos and video shots from above.
And what is the best part? Because of the tether, the drone is not autonomous. And because it is not autonomous, it falls outside of regulation on “unmanned aerial vehicles” in most cases. Especially in the United States where Federal Aviation Administration regulations on “unmanned aerial vehicles” don’t apply to tethered aircrafts.
For a long time now, I have been reading stories about drones (also known as Unmanned Aerial Vehicles (UAV) or Unmanned Aerial Systems (UAS)) and their use in surveying. Drones have altered modern-day photogrammetry by easing capturing of photogrammetric geodata, especially compared to satellites, airborne photogrammetry and traditional land surveying. They are more immune to bad weather than satellites or aircrafts, and they are much cheaper to run. All this intrigued me to buy one. But the problem was their high price, and very long and steep learning curve to properly fly them without breaking them, or hurting somebody on the way.
Until I’ve found interesting and very affordable little drone with a camera - Hubsan X4 H107C. It is small 2.4Ghz 4 channels RC quadcopter with 0.3 MP camera, 6-axis gyro and flying outdoor ability. It was a perfect way for to me to get into drones for affordable price. After some googling, I’ve found it on the Chinese webshop called Banggood. The shop has very mixed people reviews, but I’ve decided to take a shoot and ordered one from them. I also bought reserve battery and 16GB MicroSD card to have more flying time and to record video.Read on ...
