9. Geological Survey of Finland www.gsf.fi 9Geotietoydin-project A GIS-based data management system will be carried out for all geological field and map data with ArcGIS 8.1 in 2000 - 2003 The system is based on Oracle 8i (9i) database, where both locational and attribute information will be saved as nation-wide themes through ArcSDE gateway

10. Geological Survey of Finland www.gsf.fi 10Geotietoydin-project Contents of geological feature and attribute databases will be reorganized according to the work of object model-project reports (1998 – 1999) Requirements set by GTK’s quality-project to data collection and management will be taken into consideration All existing data will be imported to Geodatabases

11. Geological Survey of Finland www.gsf.fi 11 Why use digital field data capture? data validation while collected better control of field work reduces data transcription errors control of the quality of positioning speed of data collection faster field data distribution

15. Geological Survey of Finland www.gsf.fi 15 ArcPad data model Main data storage is based on Oracle 8i (9i) database, where both locational and attribute information are saved as nation-wide themes through ArcSDE gateway Geodatabase data model is used in Oracle Geodatabase feature classes are directly converted to shapefiles for Pocket PC/ArcPad users

16. Geological Survey of Finland www.gsf.fi 16 ArcPad data model Geodatabase classes (joined with relationships in Geodatabase) are converted to dbase-files (.dbf) and the one-to-many relations must be programmed in ArcPad (there is no ”join”-property) Value domains in Geodatabase are converted to.dbf- files and they can be directly linked to specified attribute in ArcPad 6 Application Builder

17. Geological Survey of Finland www.gsf.fi 17 ArcPad data model

18. Geological Survey of Finland www.gsf.fi 18 ArcPad application development User interfaces are designed with ArcPad 6 Application Builder which is installed on Windows NT or Windows 2000 Application Builder has some restrictions: –text editor is too simple –application doesn’t always work when editing xml- files with other text editor –path-definitions must be changed when transferring applications to Pocket PC device –Pocket PC emulator is missing from development environment

19. Geological Survey of Finland www.gsf.fi 19 ArcPad application development Programming is done mainly with XML and VBScript If needed, components will be programmed with embedded Visual Basic (VBCE) Applications are transferred with ActiveSync to PocketPC device

20. Geological Survey of Finland www.gsf.fi 20 Inserting ArcPad-data to Geodatabase Unique ObjectID is used in Geodatabase to link spatial feature to it’s attributes in class-tables (one-to-many relationships) This fact is taken into consideration when transferring data from ArcPad to Geodatabase: one feature and it’s related attributes are transferred at the same time to give them the same Unique ObjectID

21. Geological Survey of Finland www.gsf.fi 21MapLT a light mapping application that runs in mobile devices like PDA's and mobile phones (for example Compaq iPAQ and Nokia Communicator 9210) MapLT is written in Java and can be installed into EPOC and Windows CE devices -> platform independent User-friendly API is available for software developers, so you can even create your own mapping client! relatively low price, but requires a lot of coding

25. Geological Survey of Finland www.gsf.fi 25 Field computers operating systems: WinCe (or PocketPC) or Win97/98/2000 map interphase defines the size of the display rugged computers rare in the markets (but are coming) in some cases ordinary laptop can be used (vehicles)

29. Geological Survey of Finland www.gsf.fi 29Conclusions GTK is still at the testing stage -> decision on which software to be used needs to be done soon ArcPad is a strong candidate (but an expensive one) FieldWorker does not support raster maps, but gives good forms MapLT would be platform independent and relatively cheap, but requires a lot of programming hardware is developing fast -> it has been worth waiting for the improvements
