gdalwarp -geoloc allows you to use the complete 2d-array of latlon as georeference. With that, you can use any target CRS to reproject your data to a commonly used projection.

See my answer to this question for an example:

How to match a raster NetCDF data with a vector layer in QGIS?

Georeferencing uneven/irregularly gridded rasters
I worked on my title page, and there is some undesired vertical space before a tabular environment. I made two fboxes to illustrate the vertical distance I wanted to be the same 116 pt. But after the second box, a tabular environment starts and I assume it adds some vertical space before itself. This could be removed manually via \vspace*{-6pt}, but I am curious where does it come from?

\documentclass[a4paper, 12pt, headsepline, headings=small,]{scrreprt}
\overfullrule=1mm
\usepackage[onehalfspacing]{setspace}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[a4paper,showframe]{geometry}
\geometry{left=2cm,right=2cm,top=2cm,bottom=2cm}


\newenvironment{tightcenter}{%
  \setlength\topsep{0pt}
  \setlength\parskip{0pt}
  \begin{center}
}{%
  \end{center}
}

\begin{document}
% \topskip= x pt  % 12 pt in scrreprt
\vspace*{12 pt} % so in effect 24 pt
\begin{tightcenter}
Title \\
Title more info \\
Title more info \\
\fbox{\begin{minipage}{116 pt}  \hfill\vspace{116 pt}\end{minipage}}\\
%\vspace{116 pt}
\Large\textbf{\textrm{Huge Title Huge Title Huge Title Huge Title Title Huge}} 
\fbox{\begin{minipage}{116 pt}\hfill\vspace{116 pt}\end{minipage}}
%\vspace{116 pt}
\end{tightcenter} 
% \vspace*{-6pt}
\noindent\begin{tabular}{p{3cm}p{3.75cm}l}
&amp; Advisor: &amp; text text text\\ 
&amp; More info: &amp; text text text\\
&amp; More info: &amp; text text text\\
&amp; More info: &amp; text text text\\
\end{tabular}

\end{document}


Can I somehow remove this space other than using a negative vspace? 

Thanks.
