Can we use our own map in android?

Can we use our own map(Like our house map) and then use GPS to show where we are in the map? If it is possible 开发者_运维百科then how to do it?

You can do anything you want, but if you are asking if there is an easy way to do this, no.

You would have to produce a scale drawing, then map the pixel space to the scale of the image, know what geopoints represented the corners of your map, then project that onto your scaled display image.

Some open source products use tiled images similar to google maps, but they use OSM data, I suppose if you were dedicated you could use that and turn your map into tiles but I would think for your purposes it would be easier to do this your self.

You might check the google code repository etc. and other open source venues and see if anyone has done anything similar to this.

Also the best accuracy you are going to get is about 2m, and certainly not indoors (if you got a signal at all)
