The Google Maps feature in ERES displays geographical data using high quality on-line maps made by Google. Google Maps provides street maps, satellite maps, and terrain maps spanning the entire world. By using high quality satellite imagery, a very wide zoom range is possible, making it possible to display every imaginable area of the world. Google Maps are useful for displaying exact spots on the maps. These spots are called map points and they are marked with map markers. A powerful tool provided by ERES Google Maps is Geocoding. Geocoding can locate buildings/cities on map by knowing only their addresses. Usage of Google Maps is limited by Google Maps Terms of Service (To see the current version visit Google Maps API Terms of Service).

Google Maps can contain tool-tips and drill-downs. Tooltips are small reports or charts, which are displayed on mouse over a map marker. They display brief summary information related to the selected map point. DrillDowns are links to parameterized charts, reports or other maps, which are open, when user clicks on a map marker. They are usually used to display more detailed information about the selected map point.

SVG Maps display data on SVG (Scalable Vector Graphics) maps. They differ from ERES Google Maps in two ways. First, SVG Maps work with geographical areas (e.g. a state is marked by the whole territory, not just by a point in the middle of the state). These areas can be colored according to some criteria. Second, the SVG Maps feature requires SVG images as the map source and do not use any online map source. The SVG Maps feature may be used to display more specific and customized maps (e.g. maps of buildings, mine maps, etc.).
