Now, a series of posts listing a large number of free programs / services for doing geostatistical / geospatial analysis. Programs included will be those that specialize in this area; other general purpose GIS apps with statistical functionality (e.g. SAGA, MicroDEM, gvSIG) won’t be included. Descriptions come from the software’s website or documentation; this has the advantage of concealing my vast ignorance in this subject area. I’ll probably put biologically-oriented software in a separate series. Click on the program title to go to its website.
BayesX is a software tool for estimating structured additive regression models…BayesX is able to manipulate and draw geographical maps. The regions of the map may be colored according to some numerical characteristics.
CrimeStat III is a spatial statistics program for the analysis of crime incident locations.
CSPro (Census and Survey Processing System) is a public-domain software package for entering, editing, tabulating and mapping census and survey data.
Cyze And Associates Software
Geospatial Explorer has been written to enable geologists, environmental scientists, and engineers to apply innovative science and technology to enhance and expedite the reduction of risk to human health and the environment. Geospatial Explorer permits the user to identify, understand, and solve complex environmental problems better, faster, and cheaper.
As part of Cyze & Associates’ support for Geostatistical Analysis, Cyze & Associates provides a free Geostatistics package that compliments Geospatial Explorer by providing an interface to the SAGE 2005 variogram reports and GSLIB 2.0 kriging and simulation executables.
DMAP is a Windows compatible program that produces disease rates using variable spatial filters and tests for their statistical significance using Monte Carlo simulations. The program computes values that are inputs to GIS software that will produce disease rate maps and maps of statistical significance. Input data are either individual disease records and individual at risk records or are aggregates of the above.
Epigrass is a software for visualizing, analyzing and simulating of epidemic processes on geo-referenced networks.
With Epi Info™ and a personal computer, epidemiologists and other public health and medical professionals can rapidly develop a questionnaire or form, customize the data entry process, and enter and analyze data. Epidemiologic statistics, tables, graphs, and maps are produced with simple commands such as READ, FREQ, LIST, TABLES, GRAPH, and MAP. Epi Map displays geographic maps with data from Epi Info™.
EpiInfo – Community Edition
Epi Info™ is a public domain suite of software tools designed for the global community of public health practitioners and researchers. It provides for easy data entry form and database construction, a customized data entry experience, and data analyses with epidemiologic statistics, maps, and graphs for public health professionals who may lack an information technology background…. Epi Info™ Community Edition is the open source project to reproduce the popular Epi Info™ suite of tools in C#, with the goal of developing a data collection and analytics system for public health that is highly scalable, platform independent, and database agnostic.
Developed by the GeoVISTA Center in close cooperation with users at the National Cancer Institute, the ESTAT toolkit provides user-friendly, open-source software designed to support exploratory geographic visualization. While developed initially to support cancer research, ESTAT is designed to handle any kind of spatial data with attributes. If you have an ESRI ArcGIS shapefile, you can … quickly convert your data into something ESTAT can use.
Flowmap is a software package dedicated to analyzing and displaying interaction or flow data. This type of data is special in the sense that there are two different geographic locations connected to each data item: An origin location where the flow starts and an destination location where the flow ends. The flow data itself can be people (e.g. commuters, shoppers, hospital visitors), goods, usage of agricultural services or telecommunication and so on.
