Although the API for marker creation is not there now, if there was interest in a plugin I could add one. The KAP API is a
single HTTPS call with the coordinate, zoom,
satellite provider, API key. Within SEAiq (navigation app) the user configures SEAiq to use Vf's API key. A simple double tap on a chart requests the
satellite kap from VF. It then loads and displays it. Has to be the simplest/fastest way out there. It has been in production for about 3 years now and is responsible for about half of the 101,000 kaps created on VF.
VF's markers are limited now, I am really hopefully a better programmer than marketer. VF also does routes, which is fairly unique. Routes are markers are also available by GPX download, organized by country (this requires a database of spatial objects that defines all the land masses). This DB is not perfect but when I have
internet I tweak it. Example,
Vanuatu is a great cruising ground but not much
commercial interest.
Charts are poor and land mapping not great. I am working in VF define the forgotten islands.
VF will also do position reporting. I sort of see all these "navigation" features part of a whole, another example. Position reporting in VF can automatically know which country you are in because of the marker spatial DB. Soon, it will know when you are
offshore (minor change but I am in
Morocco now with poor internet). Why all this? You will have to trust me, I have some pretty cool features planned.
