Problem

Researchers in ecology, epidemiology, and other fields increasingly rely on spatial analysis, but are often limited by the capabilities of traditional, specialized software. Analyzing spatially explicit datasets, particularly with the increasing volume and complexity of data from sources like genome sequencing and remote sensing, requires flexible and accessible tools.

Solution

PASSaGE (Pattern Analysis, Spatial Statistics, and Geographic Exegesis) is a free software package designed to provide a comprehensive suite of tools for spatial analysis and statistics. It enables researchers to identify patterns and relationships within biological, ecological, and other spatially explicit data. With both a graphical user interface and a command-line interface, PASSaGE offers accessibility and powerful customization options for data analysis in both laboratory and classroom settings. The software supports various coordinate systems and data import/export formats, facilitating integration with existing workflows.

Target Audience

The primary users are researchers and students in ecology, evolutionary biology, environmental science, epidemiology, geology, geography, and mathematics who require tools for spatial data analysis.

Features

Supports X/Y, Latitude/Longitude, and UTM coordinate systems.
Imports and exports data in Text, Microsoft Excel, Lotus 1-2-3, ESRI Shapefiles, Surfer BLM, and native PASSaGE formats.
Includes network methods such as nearest neighbors, minimum spanning trees, relative neighborhood networks, Gabriel networks, Delauney triangulation, and tessellations.
Offers point pattern analyses, including second order analyses, bivariate & covariate analysis, and directional analysis.
Provides contiguous data analyses like quadrat variance analysis, wavelet analysis, lacunarity analysis and spectral analysis.
Performs scattered data analyses, including correlograms, Mantel correlograms, and semivariograms.
Conducts anisotropy analyses using bearing method, windrose correlograms and directional wavelets.
Incorporates miscellaneous analyses such as Mantel tests, Local Indicators of Spatial Association, and boundary detection.
Offers both a GUI for Windows and a command-line interface compatible with Windows, Linux, and Macintosh.
