With the emerging of online mapping starting from the year 2005, I can see the trend recently shifted to online data sources. With this crowd sourcing data now everybody can have their satellite images and other geospatial data for free and available online.
I’m starting to put my interest into this approach. I’m currently developing a system with the integration of these online data sources for local government agency (see snapshots below). This is 100% hard-coded program (it means no subscription to any commercial software ^.^).
Yes, it depends on the end user requirement and needs (accuracy issues, internet connectivity & others). But well, you need to decide then. Buy your own satellite images or view it without any cost?
If you’ve picked the first option, you have to rethink again if the systems is for mobile applications. Right?
