Lithologic Database


This page is temporarily pending the launch of a Windows-based well query system. 

The FGS well data and the DOS-based program that reads the data may temporarily be downloaded directly from our public site according to the following directions:

First make an “FGSLOGS" folder in the root of your C drive, then place the lithprog.exe file and the unzipped well data files into that same folder. The FGS well logs program and data are found online at the site below:

Program: http://publicfiles.dep.state.fl.us/FGS/WEB/lithologic/lithprog.exe

Well data files are in same folder: http://publicfiles.dep.state.fl.us/FGS/WEB/lithologic/  (files are zipped and catagorized by water management district name)

The program file and all data files must unzipped to the fgslogs folder.

When you first run the lithprog.exe file it will ask some questions about the path to the data file, color preferences, and printer type (just use HP laserjet). Then on a second running it will ask you to input the county name, and on first access to each county will compile and save a separate directory of wells for that county, A list of our wells for the county, along with locations and depths will then display. Since it is running in DOS, you will need to use the 'arrow' and 'enter' keyboard keys to navigate the list (mouse won’t work). When you highlight a well number and hit 'enter' the litholgic log for that well will display.

In some cases, newer operating systems such as Windows 7 - 64  bit and Windows 8 may not run DOS-based programs, and additional DOS shell software such as "DOSBox" may be required. If you need assistance please call 850-617-0318.

Instructions for using FGSLOGS and DOSBox in a WINDOWS 7 environment

Follow instructions above for downloading and installing FGSLOGS. After this is done, follow the instructions below.

1) Download DOSBox. DOSBox may be obtained from http://www.dosbox.com/ and is required for the shell to operate properly.

2) Install and run DOSBox.

3) Once DOSBox opens, you will see a dos window. In this window, type the following:

Mount c c:\fgslogs\ (NOTE: “c” is the drive letter where FGSLOGS resides and “c:\fgslogs” is the PATH to the data and program.

 If either of these are different, then use the drive letter and path you installed the program on instead.

4) Once you have mounted the drive (#3 above), then you should type:

     c:   (this is the command to change the Directory to c:\).

    This will take you to c:\fgslogs (even though DOSBox thinks the directory is just “c:\”) (NOTE: your cursor should change from something like Z:\ to C:\ indicating that you have changed directories to c:\

5) Execute fgslogs.exe (type fgslogs, then enter at the DOS prompt inside DOSBox) and answer the questions as prompted.

 IMPORTANT—when answering (entering) the PATH = statement use c:\  NOT  c:\fgslogs (apparently, the MOUNT command in DOSBOX creates an alias which makes DOSBox think that c:\ = c:\fgslogs\)

 If you use c:\fgslogs\ in the path, you will probably generate an ERROR 76 upon running the program.

Finish answering the other questions ( use printer = HPIII, printer port = LPT1, and colors 1 and 7)

At this point, you should have the program open and it will ask you to ENTER COUNTY (no drive or extension) and the program should run after entering a county name.
