Gradistat V 91 - Free

Get accurate live compass directions in the East, West, North, and South with our free online tool. Navigate effortlessly using our online compass.

How Can I Check My Directions Online?

The quickest way to navigate online is by using an online compass website. Unlike mobile compass apps that require installation on your phone, online compasses can be utilized without installation and only require an internet connection. Here's how to use our site's online compass

Geographic Directions on the Compass

On the compass image, the letter "N" represents magnetic north, while "S" stands for magnetic south. "E" indicates the east direction, and "W" denotes the west direction. Additionally, "NW" signifies northwest, "NE" indicates northeast, "SW" represents southwest, and "SE" stands for southeast.

Degrees on the Compass

The arrow symbol at the compass's top indicates zero degrees or magnetic north. The degree of difference in your current direction from magnetic north is displayed in the "Direction" section.

Activating Phone's GPS

To activate your phone's GPS, simply click the "Location services" button. You will receive a request for permission to access your phone's GPS. If you grant access, you'll not only have access to geographic direction but also additional information such as longitude and latitude.

Moreover, the compass will display your current location, the times of sunrise and sunset in that area, and the elevation of your location above sea level in both meters and feet.

Locking the Compass

The compass lock button comes in handy when you're on the move, whether you're in a vehicle or walking. In either scenario, your mobile phone isn't stationary. By enabling the lock mode, you can freeze the information displayed on the screen, ensuring that the compass no longer changes direction.

Sharing Information on social media

Another noteworthy feature of our online compass is its ability to display all the compass-related information, such as geographic direction, longitude, latitude, location, sunrise and sunset times, and altitude. Moreover, you can easily share the elevation above sea level at your current location.

Please Note: The compass must be locked to share all information.

Gradistat V 91 - Free

Gradistat V91 is an older Windows utility for analyzing and processing granulometry data, widely used in geology, sedimentology, and civil engineering for grain-size distribution, statistical parameters (mean, median, sorting), and plotting cumulative and frequency curves.

GradiStat v9.1 Free is a no-frills, deterministic tool designed for one thing: univariate gradient analysis (specifically, calculating the statistical optimum and tolerance of species along an environmental gradient). If you are a paleontologist or ecologist needing to replicate a 1990s transfer function, this is gold. If you expect graphs, intuitive data handling, or any support for multivariate analysis, look elsewhere.

Best for explaining the value to students or peers.

Title: 🛑 Stop calculating grain size stats by hand! Gradistat v9.1 (Free) is here.

Body: Hey everyone,

If you are working on your thesis or a research project involving sediment analysis, checking out Gradistat v9.1 is a must.

It’s a spreadsheet-based tool (developed by Simon Blott) that calculates standard grain size statistics using the method of moments and the Folk and Ward method. It saves hours of work by automatically generating cumulative curves and statistical outputs.

It is totally free for non-commercial use.

Hope this helps save some time during crunch week!


Gradistat v 9.1 is free, but it has limitations: no 64-bit Excel support, no automatic batch processing, and it can be unstable on modern Windows 11 with newer Excel. Here is how it stacks up:

| Feature | Gradistat 9.1 Free | Gradistat (commercial successor) | GSlope | R package ‘G2Sd’ | | --- | --- | --- | --- | --- | | Price | Free | Paid (~$100-200) | Free | Free | | GUI | Excel-based | Standalone | Standalone | Command-line | | Batch processing | No | Yes | Yes | Yes | | Hydrometer support | Yes | Yes | No | Limited | | Modern OS support | Partial (Windows only) | Full | Full | Cross-platform | | Learning curve | Low | Low | Medium | High | gradistat v 91 free

Verdict: Gradistat 9.1 remains best for students, quick analyses, and legacy data compatibility. For large-scale research (>100 samples), consider a modern tool.


Fix: This is a reference error. Open VBA editor (Alt+F11), go to Tools → References, and uncheck any missing "MISSING:" libraries.

Fix: The macro is optimized for up to 200 individual grain size fractions. For higher-resolution data (e.g., laser diffraction), reduce the number of bins or use a different program like GRADISTAT_2014 (a community optimized version).
