Simple Python utility to read in shape outlines in Shapefile format and extrude into a 3D model in Wavefront.obj format.
This script requires Python3, and the shapefile (from pyshp) and triangle modules. The matplotlib module can also be used to plot some basic visualizations where specified. These modules can be installed via, e.g.:
pip3 install shapefile triangle matplotlib
Running the script with no arguments prints a brief usage outline:
$ python3 main.py
Usage:
python3 main.py SHAPEFile prefix [key=val] [delta z]
Where:
SHAPEFile : path prefix to SHAPEFile data (don't include the file suffix!)
key=val : shape selector (if unspecified, list shapes in file then exit)
delta z : extrusion height on z axis (default: 1.0)
Example:
python3 main.py my_data/my_shapefile blah=eek 0.25
This looks for the shape in the my_data/my_shapefile.(dbf,shp,shx) file
combination filtered using whichever record key "blah" has key "eek",
and extrudes it into a 3d model of "height" 0.25 units. The output is
written to an "output.obj" file.
Assuming the presence of the Oklahoma Dept of Transport's county boundaries data set in the subdirectory counties, we may extract the boundary shape data for e.g. Logan county and extrude as follows:
python3 main.py county/COUNTY_BOUNDARY COUNTY_NAM=LOGAN 0.1
Here, we specify an extrusion length on the z-axis of 0.1 rather than the default 1.0 units. Note that the key,val data is case sensitive; using county_nam=logan rather than COUNTY_NAM=LOGAN will not work. This command results on the following output:
$ python3 main.py county/COUNTY_BOUNDARY LOGAN 0.1

As can be seen in the output above, the shape outlines have been simplified slightly. This is useful as duplicate points in the shape definition (as can be common in such data) can crash triangle's mesh generation routines.
To simply list some information about the shapes present in the file, we may omit the shape name:

Assuming the presence of the U.S. Census state boundary shapefiles in the subdirectory cb_2018_us_state_500k, and the Oklahoma Dept. of Transport's county boundaries shapefiles in the subdirectory counties, we can superpose e.g. a 3D model of Logan county onto a slightly thinner 3D model of the state of Oklahoma:
First, a 3D model of the state of Oklahoma is generated using the keyval filter NAME=Oklahoma with a width of 0.01 units:
$ python3 main.py cb_2018_us_state_500k/cb_2018_us_state_500k NAME=Oklahoma 0.01
