 Topo-Grabber - Free USGS Topographic Maps

Topo Grabber. TopoGrabber allows you to download USGS topographic map free of charge. The maps can be any resolution including 30, 15 and 7.5 minute quadrangles. The maps can be any size, including huge maps that cover dozens of regular topographic quadrangles. The maps can be printed on single sheets of paper or on multiple sheets that can be taped together to create very large maps. Click here for more information

Update and Good News: Although Microsoft announced in 2012 that it was discontinuing their Map Server that Topo-Grabber used to get its topo maps, so many people complained that they relented. As of June, 2014, the server is working as well as ever and might even more responsive than before. I have noticed occasional service outages and at times, the server is slow, but it is usually responsive in if you wait a half hour.

Since the service continues to be available, the program has been upgraded with several new features. For example, the program loads the topo maps faster and uses less system resources. There is also the option to display 7.5, 15, 30 minute and 1 degree grids lines.

 Precision Time Calibrator

The Precision Time Calibrator is a tool for analyzing and controlling the performance of the Real Time clock in a PC. The program queries atomic clocks on the internet and compares these high precision time bases to the current time in your computer. It then displays any error between your computer and the atomic clocks. The display shows the absolute error as well as a graph of how the error changes over time. This makes it easy to see exactly how much the clock on a PC drifts over time and allows you to make adjustments to correct for drift.

 Window Image Tracker

Windows Image Tracker. Windows Image Tracker (WIT) allows you to track any image on the internet over time. If the images are comes from web cam or any other source that changes over time, the images can be combined to create animations that show how the images. This is ideal for tracking weather radar, web cams, satellite images, seismograph data and many other things. The animations can be saved and play later, creating a permanent record of events. The are even tools for enhancing and editing images.

 Sports Audio Delay

New Version: Audio Delay. Audio Delay is a program that allows you to delay any audio signal fed through your PC. This is useful for synchronizing audio with another media source. For example, people often like to listen to local radio play-by-play broadcasts of a sporting event while watching the video on TV. This used to be easy because the radio and TV were broadcast without any sort of delay. However, now with satellite feeds and digital broadcasts, the video may be delayed by as much as 10 to 15 seconds. This is very distracting and ruins the enjoyment of the game.

The Audio Delay program allows you to feed your radio's audio through your computer and introduce a variable delay of from 0.1 seconds to several minutes. This makes it easy to synchronize the radio audio and the Television video.

New Features. The latest version gives the option of saving all settings as defaults and automatic start when the program is first run. There are also improved VU Meters.

 Spectrum Analyzer

Spectracizer. Spectracizer is a program that allows you to do spectrum analysis on your PC. The programs takes audio signals fed to the sound card on your computer and does real-time spectral analysis on displaying graphs the spectrum.

Spectracizer can analyze signals ranging from 1 Hz to over 22Khz. It turns an inexpensive laptop into an instrument that can replace equipment costing thousands of dollars.

The program can also analyze and dissect audio files. Finally, it can also generate synthetic wave forms and play through the PC's speakers. The spectrums can be displayed as standard graphs or as spectrograms which displays changes in the signal over time.

 Used Car Price Evaluator

Car-Buy-Rater.  Car-Buy-Rater is a program for evaluating a used cars before you buy. It works by calculating the amount of useful life left in a vehicle and how much it costs per unit. That gives you a precise estimate of the value of the car and makes it easy to see which cars are the best value. Car-Buy-Rater can save you thousand of dollars on your next used car purchase by getting you the best deal. The program doesn't require "Blue Book" values, so it will work old cars as well as new ones.

 Terrain Modeling Software

Terrain Modeling. Estierra is a complete terrain modeling software system. It converts Digital Elevation Model files into photo-realistic 3D terrain that can be viewed and manipulated in real-time. The terrain models can be overlaid with aerial photographs to give photo-realistic views of the land surface. They can also be overlaid with topographic maps to allow precise location of land marks and terrain features. This is similar to Google Earth, but the terrain models are higher resolution and narrowly focused on small areas.

 XEdit - Programmer's Editor

Xedit.  Xedit is an editor specifically designed for writing programs, but it’s also useful for writing any kind of text. Xedit is not a word processor and it does not have fancy word processing features. Instead, it concentrates on being fast, powerful and efficient. It makes an ideal replacement for Notepad.

 XPL0 Programming Language

EXPL. EXPL is a specialize version of the XPL programming language that allows for program development under Windows. This version of the language includes an IDE with a code editor, compiler and simulated DOS/VGA console that emulates 61 Standard CGA, EGA, VGA, and Vesa Modes. It also includes a debugger that allows the programmer to single step through programs, view variable values, change variable values, set break points and step through the low-level I2L opcodes that compose the program. Finally, the language includes a set of more than 40 extended instrinsics that handle the functions that would be handled by DOS or assembly language in previous versions.
