What do you mean Mobile CAD, i want just a mark up on the JPEG image
based on predefined locations , thats it.
i thot Google Map API would provide me better support of doing markup
if i am able to convert JPEG image into google map
do u have any good pointer or reference to application which does mark
up on image.

Re: [android-developers] Re: JPEG Image has a map
It just doesn't seem like a good idea to use Android Google map to display a plan view of an apartment and call out POIs within it. On my Droid, at full zoom-in, my apartment takes up about 1/12 of the screen. Also, if you placed markers for POIs within your apartment, when you zoom out, they just overlap and become useless. Is there really a compelling reason to mashup your floorplan with all the features and layers of Google maps? Is is just a specifc feature of GM you are interested in? What is that feature? I suggest you use a different approach, like simply displaying the floorplan as an image view, displaying markers on that, and providing whatever detailed callouts you want. Chances are people are working on mobile CAD apps like this. -- You received this message because you are subscribed to the Google Groups Android Developers group.
