comment How likely is it that Smartphone Camera GPS coordinates are wrong?
I am sure there is a way to change the data on the EXIF, but it is very unlikely.

comment Setting the Geometry with sql query
Without looking at the data it is a little difficult for me, but you could look at table joins or spatial joins. I am assuming you have some data with birth rates (points or polygons). If the birth rates data has any attributes related to the state, then you could do a table join with the state polygon to put that data into the state table. Otherwise, you may want to do a spatial join. Going about this will depend on how your data is put together.

comment Setting the Geometry with sql query
What software are you using to do this. A shapefile is not a database, and the query you are using is specific to a spatial database (ie: Spatialite, PostGIS, etc.). If you want to do those types of queries you will want to put your data into a spatial database (like the types mentioned above).

comment Image classification using google satellite images
You could do that, but be careful about having hard and fast rules. One of the issues with classification is that it uses real world imagery; and real world imagery has variation. Setting a RGB value may result in different classes depending on the temporal and spatial location of the image. If you will be using a repetitive location (ie: time series analysis) then you may be ok. But if you are not, or you will be looking at temporal change, then you will have to deal with a feature having different pixel values at different times of the year (ie: trees). Also don't forget about clouds, etc.
