Apple Acquires Indoor Mobile Location Positioning Firm WifiSLAM

The race for improved indoor navigation goes on, MacRumors informs us that Apple Acquires Indoor Mobile Location Positioning Firm WifiSLAM.

From the Wall Street Journal: "The two-year-old startup has developed ways for mobile apps to detect a phone user’s location in a building using Wi-Fi signals. It has been offering the technology to application developers for indoor mapping and new types of retail and social networking apps. The company has a handful of employees, and its co-founders include former Google software engineering intern Joseph Huang. [...] Google already offers indoor mapping in certain locations like airports, shopping centers and sports venues."

Indoor Navigation On Your Smartphone, Using the Earth's Magnetic Field

Earlier this week Slashdot discussed a story named Indoor Navigation On Your Smartphone, Using the Earth's Magnetic Field.

Their summary: "Researchers from the University of Oulu in Finland has created an indoor navigation system (IPS) that uses the Earth's innate magnetic field to ascertain your position — just like a homing pigeon or spiny lobster. According to IndoorAtlas, the company spun off by the university to market and sell the tech, its system has an accuracy of between 0.1 and 2 meters. The Finnish IPS technology is ingenious in its simplicity: Basically, every square inch of Earth emits a magnetic field — and this field is then modulated by man-made concrete and steel structures. With a magnetometer (compass), which every modern smartphone has, you can first create a magnetic field map — and then use that map to navigate the shopping mall, underground garage, airport, etc. Compared to most other IPSes, which require thousands of WiFi or Bluetooth base stations to achieve comparable accuracy, IndoorAtlas' infrastructure-free approach sounds rather awesome."

This is an approach we mentioned in February 2011 when Samsung indicated they we planning the use of the magnetic field for indoor navigation, but I haven't seen any related product yet.

Researchers Track Cell Phones Indoors By Listening In

The second discussion over Slashdot this weekend was named Researchers Track Cell Phones Indoors By Listening In.

Their summary: "Researchers at Northwestern University and the University of Michigan have developed a technique which aims to extend the reach of mobile phone location tracking. Their free iPhone app, Batphone, extracts a location 'fingerprint' from a short recording of ambient sound. This software-only approach allows the device to determine its location with high accuracy using its built-in microphone. Unlike prior indoor tracking techniques, Batphone does not rely on the presence of Wi-Fi access points to serve as landmarks, although these can be used to assist the system when available. They also posted a web game which allows you to test your own ability to recognize rooms by listening. Technical details are in a paper which was presented at the MobiSys conference on Thursday. This is from the same people who brought you laptop sonar."

Announcing the New CDV Systems “BIM & CAD to GIS Workflow” Video

Since 1992, CDV Systems has been providing BIM & CAD training, implementation and technical support services to the engineering, architectural design and construction (AEC) industries. Our experience in managing full lifecycle Building Information Modeling (BIM) projects has given rise to a breakthrough workflow which extends  BIM & CAD data into the geospatial realm.

The AEC industry has found real success by planning, designing and constructing facilities using BIM technology. There is now an industry-wide awareness that when GIS data and BIM models are combined, an indoor GIS can be developed which offers dramatic improvements to the operation and maintenance of buildings.

Yet, full-scale repurposing and integration of this rich BIM data for indoor GIS use has been limited.

Design data residing in proprietary BIM software formats lingers as an underused resource. It is often bound by non-standardized file structures, bloated BIM databases and format conversion losses.

The CDV Systems “BIM & CAD and GIS Workflow” is a flexible methodology which allows legacy 2-D and 3-D CAD/ BIM data to make its way into the GIS environment in a more manageable fashion than was previously possible. The ability to smoothly absorb these disparate data sources into an enterprise GIS server paves the way for standing structures to employ exterior, interior, and subsurface GIS.

Indoor GIS raises facility return of investment to its upper limits by connecting to traditional enterprise GIS deployments and back again to the CAD/BIM environment.  The convergence of CAD, BIM and GIS brings advanced capabilities to GIS applications and in turn added value to the AEC industry.

We think that this short video entitled: ‘CDV Systems BIM & CAD to GIS Workflow’ will hold the interest of CAD, BIM, GIS and Facility Managers alike.
