IBM’s Smarter Planet initiative keeps marching on, and its latest stop is the city of Corpus Christi, Texas. Big Blue is helping the Gulf of Mexico port city with software that monitors water, roads, airport, parks, and utility infrastructure, with the goal of tying those disparate city services into a single view for more efficient operations. It’s similar to “Smarter Cities” initiatives IBM has underway in about 300 cities around the world, from capitals such as London, Stockholm and Dublin and major metropolitan areas such as Amsterdam and Sydney, Australia to smaller cities like Dubuque, Iowa, where IBM is helping revamp water and energy management. Cisco is another IT giant with smart city aspirations. The networking gear giant’s Connected Urban Development initiative has projects including networked schools in Portugal, energy efficient apartments in Spain, and an “EcoMap” of the carbon emissions from energy use, waste management and transportation patterns in San Francisco.
