Apple, Google: Battle of the Cloud Maps
Nerval's Lobster writes "Google has sent invitations for a June 6 event in which it will apparently unveil 'The Next Dimension of Google Maps.' Meanwhile, rumor suggests Apple is preparing its own mapping service for iOS devices. The escalating battle over maps demonstrates the importance of cloud apps to tech companies' larger strategies." I only wish my phone would hold by default the X-million data points that my outmoded (but cheap and functional) dedicated GPS device does, without quite so much cloud-centric bottlenecking, and leave all expensive data use for optional overlays and current conditions.
As a contract job for Galileo (the main offline map for iOS, http://galileo-app.com/ I wrote a parser for the OpenStreetMap data. Those "X-million data points" fill 800 MB in txt.bz2 format, or 8 GB in plain text. That's why they're not provided by default. Anybody interested in parsing the 25 GB OSM planet database can contact me; I'd be happy to help. There are a few awk scripts I wrote that made it quite straightforward, and fast. You can then use BashServer (Cydia) and lighttpd on the phone, with bookmarks added to your home screen, to make an "app". The icon loads a local webpage (127.0.0.1/Scripts/poi.html), which runs Javascript to give a dialog "Enter search terms". Clicking OK triggers BashServer to run the associated shell script to generate a KML with the search results. The script then opens tells iFile to open the KML, which gives a popup asking which application to open it with. Choosing Galileo launches the "Import KML" feature, and your search results are in your offline map! Simple as that ;-).
