Not everything at Nokia is a distaster - Take the Ovi Maps department as positive example

Recent news about Nokia have not been very positive. First there was the anouncement that Nokia will do a partnership with Microsoft and replace their legacy mobile operating system Symbian with Windows Phone 7. Later Nokia informed the press that they cut 4000 jobs world wide - All in all they do not perform well recently and mobile competitors head away.

But eventhough Nokia faces a though time there seems to be one department within the concern who brings innovation after innovation and surpises with great new products. The OVI map group at Nokia does a great job. Recently the have announced OVI Maps 3D. This thing will blow you away. If you think Google Earth is cool then you will be thrilled to see OVI Maps in 3D. This piece of technology puts Google Earth Tech to Shame.

Ovi Maps 3D is 3D aerial mapping on the block. The technological background comes from a company called C3 Technologies, who has now partnered with Nokia to deliver the first usable version of its mapping data with Ovi Maps 3D. Developers of C3 technologies, took hardware originally used in missile guidance systems and adapted it to photography to capture extremely accurate 3D images.

Ovi Maps 3D currently features 20 cities

Take a minute to play with the maps and get a taste for how they differ from the flat images of Google Maps. Of course, Google Earth can do 3D, too. But not like this. Let’s take a look at the advantages offered by C3’s mapping technology.

Part of the process of building Google Earth involves using Google SketchUp 3D modeling. That involves people putting parts of maps together manually. C3’s map data, by contrast, is assembled almost completely automatically. C3’s planes are outfitted with DSLRs pointing every which way, capturing overlapping images to produce complete 3D images. All those pictures are then processed through custom machine-vision software to gauge the depth of the 3D and assemble the map data.

Traditionally, this sort of mapping is done using LIDAR, a process that uses lasers to gauge the size and shape of 3D geometry. And LIDAR is expensive--by relying on cameras and software, C3 is saving money while producing detailed maps. Usually photography requires manual correction, but C3 claims its process is 98% automated and requires little cleanup.

C3’s images, viewed in Ovi Maps, are definitely more detailed than what you’ll see in Google Earth--and they pop into focus more quickly, too. The texture resolution isn’t great up close, and the map software clearly has trouble figuring out the shape of foliage, but the potential here is amazing. And since C3’s already partnered with Nokia, this mapping software could make its way to Windows Phone 7 at some point.

C3 has adapted its methods for ground use on cars and boats and one day hopes to map the insides of buildings, too. Thanks to C3 and the augmented reality apps of the future, someday you’ll be able to tell exactly how many centimeters away the nearest Starbucks is.

Tesla Model 3 - Dashboard Concept

Will 2017 be the year of Tesla Model 3? At last years Telsa Model 3 introduction event Elon Musk stated that first Model 3 will be shipped to customers by the end of 2017. Latest news show that currently production lines are set up and first Model 3 shall be produced by July 2017 and delivered mainly to employees as beta tester. For this reason it is very likely that we will see some Model 3 on Californias roads by mid of this year. Some expert expect the total production of cars for 2017 to 30000 up tp 50000 cars, where high production rates will be reached not before 2018.

The design of the Model 3 is well known since the introduction event back in March 2016, and it is expected that the outside will not change much. But there are some roumors that there will be quite some changes on the interior of the car especially the dashbord.

Recently I came across a new dashboard study. Have a look here.

ArcGIS 10.1 Beta Launch and Deprecation Plan

ArcGIS 10.1 Beta 1 is now available for download to all those that have registered and been accepted into the program. Downloads have been made available from the Customer Care Portal and information and how to access this can be found on the ArcGIS Beta Community Site. This site is the portal for all information related to the beta.

One big drawback of ArcGIS 10.1:
There is no change in Desktop at 10.1 in regards to 64-bit support. ArcMap is a 32-bit application, but ESRI do support it running on 64-bit Windows. Currently ESRI is workung on a research project for native 64-bit ArcGIS application but it is not going to make 10.1.
ArcGIS 10.1 Deprecation Plan:
ARCGIS DESKTOP 10.1 ArcGIS 10.1 will no longer support the Solaris versions of ArcReader and ArcGIS Engine.ArcGIS 10.1 will be the last release supporting ArcReader for Linux.  SUSE Linux Enterprise Server 11 and Red Hat Enterprise Linux Server 5 will be supported.  However, SUSE Linux Enterprise Server 10 and Red Hat Enterprise Lin…

Precize 3-D model of Mount Everest

The highest mountain on earth is now available as 3D terrain model free for download. The resolution of the model is 50 by 50 cm. Not everyone can climb the Mount Everest (even though several hundred cimbs are registered each year, and still claim their victims) from their living room.

Scientists of the DLR (Deutsches Institut für Luft- und Raumfahrt) together with 3D Realitymaps and Digitalglobe have calculated a realistic three-dimensional model based on satellite imagery. The software for calculating the model was originally used for making 3D models of Mars. According to scientists currently it is not possible to create a more precise model based on civil satellites. The 8848 meters high mountain was recorded by various satellites and different angles. These data builds the foundation of the terrain model and 3D textures. To use the model on your personal computer you have to install a special viewer which can be downloaded via htt…
