|

|
||||
For the curious users it may be useful to see how the analysis was executed.
|
||||
Also, given the source listings, it should be relatively straightforward to
|
||||
re-run the same analysis on a different area.
|
||||
We strongly believe that ability to reproduce the graphs here is critical for
|
||||
the longevity of the work. Therefore we have added all the source files of
|
||||
this report to the PDF document itself. To extract the files (and, if
|
||||
desired, re-generate the report), run this simple script:
|
||||
|
||||
The analysis was executed and report was generated on Ubuntu 20.04 with only
|
||||
system packages. This should be sufficient: {\tt postgis gdal-bin biber
|
||||
latexmk texlive-bibtex-extra python3-geopandas python3-pygments}.

This file binds all the pieces together:
|
||||
\begin{itemize}
|
||||
\item Prepares the PostGIS database.
|
||||
\item Generates helper figures (sine waves, squares).
|
||||
\item Runs analysis on input files ({\DP}, {\VW}, Chaikin).
|
||||
\item Invokes {\tt latexmk} as a final report generation step.

||||
\end{itemize}

|
||||
\subsection{layer2img.py}
|
||||
This file accepts a layer (or two) and generates a PDF image suitable for embedding into the report.

|

\subsection{db}
|
||||
Manages a PostGIS database in the Docker container. That way, the database can
|
||||
be torn down and re-created by automated tools like the {\tt Makefile} itself.
