 +====== Geodata Workbench ======
 +
 +The geodata workbench ​ is experimental. Interface and functionality will change with growing experience.
 +
 +The geodata workbench for short:
 +
 +There are 4 entries in the menu
 +
 +  *Import OSM Map
 +  *Navigator
 +  *Import OSM Heights
 +  *Create Houses
 +
 +
 +====Import OSM Map====
 +read all information for a given position from osm
 +There are still problems with the mass of data inside FreeCAD.
 +I have played with kthread but still not realy lucky.
 +
 +
 +First run the script without Process Elevation Data
 +Processing output says: "got data from openstreeetmap.org"​
 +progress bar stops at 0%
 +
 +Then run again with "​Process Elevation Data"
 +Processing output says: "​import fnished"​
 +progress bar stops at 100%
 +
 +result: buildings are placed in the right height
 +
 +Then run Menu - Geo Data -> Import OSM Heights
 +with the same coordinates
 +to get the ground profile
 +
 +====Import CSV====
 +  *Import a path from a file in csv format or 
 +  *direct input of data into a multiline editable text field
 +
 +The data are lines with latitude and longitude separated by semicolon or white space.
 +
 +The method needs the filename of the csv.file or the textdata and a reference point (origin with its latitude and longitude.
 +
 +
 +
 +====Import GPX====
 +
 +Imports a gpx-track data file.
 +
 +The methodes needs a reference point (origin with its latitude and longitude) and the information about the height of the startpoint relative to the  origin.
 +
 +With the option "​generate datas nodes" for every gpx track two mathplotlibnodes and a numpy node is generated.
 +
 +
 +====Navigator====
 +
 +tool for free navigation style
 +needs fine tuning for geodat dimensions:
 +speed, height for walker or car
 +
 +The idea is to be able to run, drive, fly in the model
 +
 +====Import OSM Heights====
 +reads height information for a reectangle
 +input: len, lat
 +
 +hard coded size parameter 30 generates an area pof about 3 km x 6 km
 +
 +The idea is to get height information and create a landscape for a givben position
 +The data are still requested from google instead from osm
 +
 +
 +====Create Houses====
 +create a LOD2 model of a house
 +
 +Length and Width
 +Height and Heught of the roof
 +4 parameters to define the geometry of the roof
 +
 +To bring the house into the osm map
 +Position on Earth
 +Orientation/​Rotation relative to North
 +
