<div dir="ltr">Interesting problem - however I should direct you away from geotools-devel (which is focused on making great software) and towards either our users list (how to use GeoTools) or <a href="mailto:discuss@osgeo.org">discuss@osgeo.org</a> (generally questions).<div>
<br></div><div>The OSGeo foundation offers a list of service providers here: <a href="http://www.osgeo.org/search_profile">http://www.osgeo.org/search_profile</a> if you wish to look for help in your neck of the woods.</div>
<div><br></div><div>I am not sure that the Google Earth / Bing maps would have the detail you require (you may need to check their license terms to ensure a solution built on their technology would be cost effective). That said they are a good resource for your second point - that of geocoding (i.e. property address or GPS coordinate).</div>
<div><br></div><div>I have seen similar calculations does based on digital elevation module, you can identify what direction a property is facing for identification of an appropriate crop. I am not aware of a data provider that provides elevation data roof by roof in order to determine slope.</div>
<div><br></div><div>There are a couple of advances though, the US cleared higher resolution imagery for domestic use - perhaps the rest of the world will as well? And there is a rise of small satellite providers who may be able to step in with data products of appropriate detail.</div>
