Introduction

I do programming for a living and I love to program. In my spare times I created a few programs that seem somewhat useful to me. I thought someone else might also be interested in them. I have considered releasing them as Shareware but I don't think I have the time to responsibly support them as Shareware. So, here they are. You are welcome to use them for your own private personal use. If you are using them for financial gain in any way, please, obtain my written permission.

Revision History:

001206: updated Myterra to use NetFirms server because MyCGIServer no longer support Perl script.
990506: added Amateur Radio AX.25 Baycom packet radio interface for GPS tracking (including sample program source code for packet processing).
980812: added PCX file support and fixed cursor x/y readout error.
980710: added 3.75 minute grid.
980513: UTM to long/lat conversion has been changed to use the correct ellipsoid corresponds to DLG's NAD27 CONUS.

Details:

This program receives realtime GPS coordinates from a GPS receiver and display the position on USGS DLG maps, Tiger sinusoidal projection maps, or rectangular projection maps.
Why do you want this program:
- Reads the 100k USGS DLG maps available free from the USGS US GeoData (goto 1:100,000 DLG and link to 'FTP via Graphics') or USGS sorted by map names or GLIS sorted by states or goto 1:100,000-Scale Digital Line Graphs for more information.
- DLG maps includes 4x4 trails, great for Off Highway Adventures.
- Realtime GPS moving maps.
- Runs on HP200LX palmtop computer.
Notes on getting DLG maps:
- The USGS ftp site are not always up. Keep trying. I sometimes have better luck with the ftp.exe program in a DOS prompt; the ftp site is sometimes so slow that the browser times out before the ftp server responds. The DLG maps are also available on the CD-ROM from USGS GLIS Product Prices.
- The USGS ftp site keeps all maps under sub-directory of the first letter of the name of the map. You can use this if you know the name of the map. It you don't know the name, use the GLIS site (it eventually also goes to the USGS site.)
- For example, I want to retrieve map of Boston:
  1. goto GLIS site
  2. goto Massachusetts
  3. goto Boston East
  4. goto transportation (other sub-directories contain the indicated features.)
  5. goto BO3.RDS31.opt.gz (getting the south-eastern most piece (1/16) of the map)
  6. save the GNU compressed file as BO3_RDS3.GZ
  7. gunzip (gzip-1.2.4.msdos.exe {my browser won't go there:( }) BO3_RDS3.GZ to uncompress
  8. dlg -h640 bo3_rds3 to view it

The OlyExif Utility is a collection of utilities for preparing JPEG pictures for uploading back into the digital camera. You still need Camedia that came with the camera or CameDOS for upload.

TIMKEEPR is a time control tool for office meetings. It runs best on the HP200LX but may also runs on any standard XT compatible computers. It is basically a count down timer. Length of time and interval are given on the command line. At every interval, it displays the remaining time in large font, beeps, waits for five seconds, and shuts off. When the count down stops, it displays a message and beeps.

TripPlan 1.0

Download TripPlan 1.0

TripPlan is a simple tool for visualizing local times for long distance (8 or more time zone differences) flights. It simply creates two time lines corresponding to the two time zones. With the time lines, one can quickly visualize the local times at both locations for time planning, e.g. sleep planning to minimize jet lag.

PV is a bi-level PCX graphics file viewer. It runs on the HP200LX as well as any standard XT compatible computers. Two unique features make it especially useful on the HP200LX:

The entire image is loaded into the RAM for fast scrolling and panning.
The entire 640 x 200 CGA screen may be divided into up to 8 horizontal stripes for displaying a thin stripes of an image wider than the horizontal screen resolution of 640 pixels. This allows a thin but complete horizontal stripe of an image up to 5120 pixels wide to be visible at once. This is particularly useful for reading the text of a faxed document whose paragraph that is as wide as the page.
