Enhancements...
- DONE, Buttons lassen (keine Toolbar), kein "Title"-Feld.
- DONE, Alle Menu items und Buttons "Import " und "Export " mit "..."
- Flag: Set backround color to white (jpg, default: off) nach Rotieren
- DONE, Bei Änderungen "Data has changed. Do you really want to quit?"
- DONE, Vor speichern einer gleichnamigen Datei, warnen: "File already exists. Do you wan to overwrite it?".
- DONE, Bei Pull down menu "Map Type" fehlt "others".
- DONE, Es heisst "World File", bzw. "World file".
Später:
- In Swing umschreiben - gute Übung zum Vergleich.
Workflow
- Get image to be referenced about a region on earth; e.g. a floor plan from a building ('building map').
- Start Google Earth, create "New overlay..." and georeference image.
- In Google Earth export overlay as KML (not KMZ) "Save As..." (WICHTIG: Speichern als UTF-8!).
- Start WorldFileTool
- Choose "Open KML..." (which includes already overlay title, image name, bbox)
- (optional) or 1. open image file (e.g. jpg), take worldfile (e.g .jpw)
- adds metadata in GUI (if needed):
- floor (-99..99, default= 0)
- priority (1..100 i.e. 1= highest, 0=unknown, no default!)
- map type '<background> (2=Others, 1=Landkarte, 0=Gebäudeplan, default= 0)
- name (String, falls nicht vorhanden (Worldfile) default "Karte/Plan ohne Namen")
- using WorldFileTool do either...
- "Save KML" again (note: rotate image to north if needed, see below)
- (optional) Export world file
- (optional) Generate 'background map' (includes KML and image) (internet access required).
- Use georeferenced image in your GIS viewer (e.g. IndoorWPS), map server or GIS.
There exist alternatives to georeference an image: See GISpunkt Wiki (german) and freegeographytools.com.
Specifications
Floor: Stock. ACHTUNG:
- Erdgeschoss => first floor (en_GB: ground floor)
- 1. Stock => 2nd floor (US)
KML:
- Examples to test load/import (KML without metadata, image):
- http:files/amklusbach.zip
- Building map example to test export (KML, image):
- http:files/gebaeude.zip
- Background map example to test Google Maps export (KML, image):
- http:files/background.zip
- KML with priority
- (?upload)
Input with "unwanted" rotation parameter; image needs to be rotated to 'north', so that <rotation>-49.84368795876157</rotation> can be left out (= <rotation>0</rotation>):
