New From FOLPI

This option allows a new problem to be defined using data contained in files formatted for use with another forest estate modelling program called FOLPI. These FOLPI formatted data files commonly have a .dat suffix. The compulsory information for LOG is area, yield and product information. Thinning, overhead and planting information are optional extras to include in LOG. If the user only has seperate files instead of one .dat file then the user can create the necessary .dat file by using IFS, which is a common Forestry program. This option may be available through LOG in the future. In LOG the New From FOLPI option will display a form similar to the figure below.

This form prompts the user to specify the name of the Data File and Problem File created by LOG. The ‘Save As’ button opens a window that allows the user to specify a file name and location for the appropriate LOG Data or Problem file. This process essentially creates databases in Microsoft Access for the data and problem information. Having the databases is useful as changes to any information can easily be made. The readability of information in the databases is significantly better than that of .dat files. 

Once 'OK' is pressed temporary databases are created for the LOG data file and the LOG problem file. These have to be saved at some stage before exiting LOG if the user wants to keep the files. This is because the temporary files are deleted when LOG finishes. After 'OK' has been clicked, LOG will take the user to a problem summary screen.

 

New From LOG

This option allows for a new problem to be defined using data contained in a pre-existing LOG Data File. Selecting New From LOG will open a screen similar to that in the figure below. The first part of this form allows for the LOG Data File to be located and opened using the ‘Browse’ button. Selecting ‘Save As’ in the second section of the New From LOG form opens a window that allows the user to create a new LOG Problem File. The user will need to specify a filename and location for this file.

Once 'OK' is pressed Temporary Databases are created for the LOG data file and the LOG problem file.

 

 

Open Problem*

A new feature of LOG is that there are now two ways to open a problem. Either the data file and problem file can be loaded, or only a problem file can be loaded. Both  options are used to open a pre-existing LOG problem for which LOG Data and LOG Problem Files have already been created, the only difference is that one opens up the data file, while the other option assumes that the appropriate data file is already open. On selecting the option to open both the data and problem files, the following window will appear.


This window allows for the user to browse for the desired LOG Data and Problem files using the appropriate ‘Browse’ buttons. Press ‘OK’ once the desired files are displayed or ‘Cancel’ to return to the LOG Introduction Screen.

Once 'OK' is pressed Temporary Databases are created for the LOG data file and the LOG problem file. LOG then brings up a problem summary screen.

 

The window below  appears when the 'Open Problem' option from the file menu is selected. It is important to ensure that the problem being opened relates to the data set that is currently loaded.

This window allows for the user to browse for the desired LOG Problem file by using the ‘Browse’ button. Press ‘OK’ once the desired file is displayed or ‘Cancel’ to return to the LOG Introduction Screen.

Once 'OK' is pressed a Temporary Database is created for the  LOG problem file. LOG then brings up a problem summary screen.
