Street Smart: 3D City Mapping and Modeling for Positioning with Multi-GNSS

July 1, 2015By

A particle-filter-based positioning method using a 3D map to rectify the errors created by multipath and non-line-of-sight signals on the positioning result delivered by a low-cost single-frequency GPS receiver takes a multi-GNSS approach, using the combined signals of GPS, GLONASS and QZSS. The method outperforms conventional positioning in availability and positioning accuracy. It will likely be fused with other sensors in a future pedestrian navigation application. read more

Ride Service Uber Acquires Mapping Company DeCarta

March 18, 2015By

Ride service Uber is buying mapping and search startup deCarta, reports Mashable, which said it learned of the deal from an Uber representative. The deal was expected to close earlier this month. Uber plans to use deCarta’s technology and talent to fine-tune its products and services that rely on maps, including UberPOOL, the smartphone-based ride-sharing app. Thirty out of 40 deCarta employees will... read more

Geomatics Offers Portable Surveying and Mapping System

March 3, 2015By

Editor’s note: GPS World explored use of the new system from Geomatics in the March 2015 issue. Geomatics USA from Gainesville, Fla., has designed a precision surveying and mapping system that can be easily stowed in an overhead compartment for airline travel. Surveyors can fit everything needed for important mapping and surveying jobs into a baseball-style bag, including tripods. The compact, light-weight system offers differential sub-foot accuracy.... read more

A Milestone in Digital Mapping

February 25, 2015By

Hard to believe, we have only now reached the 10th anniversary of Google Maps. As important as digital maps have become, their purpose is much the same as the printed and drawn maps that preceded them. Digital maps emerged in the 1960s with the Census Bureau’s DIME maps. These first digital maps were used for analysis of place-specific data, such as populations within census tracts or cities. Digital maps in turn led to geographic information systems (GIS) for spatial analysis. Though GIS had uses in fields like city planning, the main stimulus for digital maps came in the 1990s with the convergence of the completion of GPS infrastructure, and affordable and portable computers. read more

How does our brain understand where our body is in space, and navigate us from home to work? The components of Google Maps are easy for us to discern. We readily understand the mix of GPS location, an extensive map and a sophisticated way-finding algorithm. Our ability to understand our body’s innate relationship to location is far more complex. Discovery... read more
