The Memory Map application for mobile phones and PDA’s is fantastic example of software development for mobile devices. This application has been around for some time, and is the work of US based developer Richard Stevens and his team. Richard is a software developer with 15 year’s experience in scientific super-computing and high-performance real-time systems such as medical imaging machines and high-end radar systems.
From the MemoryMap web site …
“Memory-Map Weather Radar is an application to display live National Weather Service doppler radar images and animated loops from radars located throughout the United States. Radar is the most effective tool to detect precipitation, especially thunderstorms, and has been used by NWS forecasters since the 1940’s. Memory-Map now brings this information, conveniently and efficiently, right to your phone or PDA.
With Memory-Map Weather Radar, when you update the image, the radar data is downloaded as a compressed overlay, without having to download the whole base image each time. There are no usage fees or subscriptions for using the service, except your mobile carrier’s normal data access fees. If the sky is clear, the download is only 1 or 2 kbytes; if there is widespread rain, it might be 10 kbytes. The first time you view each radar station, the base map image is downloaded, which is 50 to 100kbytes….”
Although the radar product is limited to the USA, what I didn’t realise is that his company has produced a full navigation product Memory-Map Navigator – for hiking and sailing that covers the UK!. Take look at the excellent video here.
This takes the use of the built in GPS on a smartphone into a whole different realm….
