Perform topological analysis on 2D map data.

To build map2model:

• If you want to install standalone map2model with Cmake, comment out the pybind11 include in map2model.cpp and parameters_reader.cpp and parameters_reader.h, and code after the main function in map2model.cpp.

mkdir build
cd build
cmake ..
make

To run:

./map2model ../Parfile

Visualization of output

To visalize output images (.svg file) use e.g. a util 'display' (Linux), or Firefox.
To visalize output graphs (.gml files) use e.g. yEd Graph Editor (cross-platform).
In eEd program, to see a graph, choose e.g. Layout --> Organic.

Input data format convertion

To convert shape files data to WKT data in UTM coordinates, use ogr2ogr util. Run script shp2csv.sh
To convert a single point in lat/long coordinates to UTM use gdaltransform util as:
gdaltransform -s_srs EPSG:4326 -t_srs EPSG:32750
and then type the point coordinates separated by a space, and press Enter.

Outputs description

An output image 'polygons_read.svg' shows all input polygons that were read, with marked clipping window.
An output image 'polygons_clipped.svg' shows the result of clipping of the input polygons with the clipping window.
An output graph 'graph_all.gml' shows topology for units, i.e., nodes correspond to units, and edges to unit contacts.
An output graph 'graph_no_sills.gml' shows same info as 'graph_all.gml', but contacts with units of type 'sills' are excluded.
