jpstools's Introduction

jpsTools

tool for converting osm-data into jupedsim geometry files

Requirements:

Python3
shapely
pyproj
matplotlib
lxml

How to:

Download openstreetmap data for a specific area. In terms of being able to manually edit the data I recommend using JOSM (JavaOpenStreetMap-Editor)
Save the data of your choice as an .osm file
Run jpsTools.osmImport.main() with command-line argmuents [1] the folder of your osm file and [2] the filename e.g. 'resources/ Meckesheim.osm' [3] 'handle' if you want jpsTools to translate ways by attributes polygons and define transitions. leave [3] empty if you only want to convert a finished and edited .osm file.

Configurations

inside jpsTools.osmImport.main() modify or define as many filterTags and unhandleTags as you want. Depending on your the local osm community and their 'dialects' tagging might differ
filterTags describe which elements to load and handle from your osm file. If an osm element contains the key-value pair it will be used.
unhandleTags are currently used for nodes, which aren't supposed to be adjusted. e.g. Tag: 'elevator'='yes', it is not our aim to merge paths on either side of an elevator.
Check what tags you want to translate by playing around with your downloaded elements in JOSM
The tag 'width' = XX describes the width of an element in meters. If you know the shapes of you environment you can add the tag to any element and jpsTools will use the value to buffer its size.
Closed ways (first node equals last node) tagged 'area'='yes' are defined as areas and will not be adjusted in size.

jpstools's Issues

String convert?

I have a question to this line,
which gives me a SyntaxError: invalid syntax

Do you mean to convert i to a str? (str(i))

obstacles

handling obstacles not implemented yet

elements crossing each other

another case that is not properly handled yet

exit transitions

how to recognize exit transitions to the outside (end of the simulation)?

structure for unordered elements

no attribute 'iteritems'

Running

python main.py

gives the following error

consistency of element id's

defining proper exceptions

define custom exceptions. catch them to not handle elements

convert to sumo

linestring transitions

what if a transition consists of more than two points?
required: algorithm to connect end points of the linestring with a single line and adjust the relevant polygons

convert back to osm

you could then easily use josm for readjusting wrong geometries manually

how to manually adjust geometries?

output to could be written as osm-readable xmls. we can than easily an manually adjust them in josm
advantage: if we later compile a josm plugin the whole process stays inside a single tool
own interface
advantage: we can easily specify the allowed tools and constraints

-geojson:
advantage: standard format. accessible from e.g. QGIS

translate goals

define closed areas as goals in josm

tags:
area=yes
jupedsim=goal

switch to external osm library

e.g. imposm

Howto

Could you please explain what you mean with "Define input and output"?

It is possible to make a small video for this HowTo?

double tagged geometries

need a method to handle geometries within another geometry.

Example: A path (highway=footway) can be inside a polygon (indoor=corridor, area=yes).
We need to decide about which object to choose.

inner/outer polygons

handling inner polygons not implemented yet

Module missing?

  from pyproj import Proj
ModuleNotFoundError: No module named 'pyproj'

Something missing?

add consistency checks

are all polygons valid?
connecting points connected to relevant ways/polys?
original ways inside the equivalent poly?
...

transitions not always determined

sometimes transitions between rooms are smaller than they should be:

sometimes transitions aren't recognized at all. happened if one room has multiple transition with another room
