+\subsection{Overview}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\begin{frame}[fragile]{Overview}
+
+Remote Sensing has been a limited topic in GRASS
+\newline\linebreak
+
+\begin{itemize}
+ \item GRASS 5: Raw images (esp. aerial photos)
+ \item 1990s Public: AVHRR (1100x1100m)
+ \item 2000s Public: MODIS (250x250m)
+ \item 2010s Public: Landsat (30x30m)
+\end{itemize}
+
+Rekindled strong interest from the geospatial community.
+\end{frame}
+
+\subsection{Imagery}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\begin{frame}[fragile]{Imagery Functionality}

+\end{itemize}
+\bigskip
+Modules also have development stages, \\
+from experimental (add-ons) to stable (main).
