Platform: Windows

Last update: 2008

All descendants of the original JumpGIS (as is gvSIG as well), originally funded by Canadian government entities. (as is gvSIG as well). Great vector editing capabilities. The best ones to check out are OpenJump, which tries to incorporate improvements from the other versions, and Kosmo, still open-source but being developed and expanded by a commercial company.

Key Indicator Data System (KIDS)

Platform: Windows

Last update: 2007

“The Key Indicator Data System (KIDS) has been developed by the World Agriculture Information Centre (WAICENT) of the Food and Agriculture Organization of the United Nations. KIDS is a software framework that provides the ability to implement thematic information systems that collect, reference, visualize, exchange and disseminate statistical, survey and indicator data. Visualization is possible through tables, mapping, raster images and graphs. Basic GIS overlay and legend editing functions are available for non-GIS users.”

LandSerf

MapMaker

Type: Free limited version; full-feature version installs as 30-day demo, reverts to free version at end of evaluation

Last update: 2008

A great mapmaking program, though the interface takes some getting used to. Also has vector editing and analysis functions, but after the 30-day demo has expired, can only be saved in a proprietary format in the free version; export into standard vector formats (SHP, MIF, DXF) requires the full version. But licenses for the paid version, Map Maker Pro, are available for free to not-for-profit organizations, educational establishments, and students in Africa.

MapWindow

Platform: Windows

Last update: 2008

A great GIS program from Idaho State University, with excellent vector-editing capabilities, plus a host of useful utilities; do a search for MapWindow on this blog for examples.

MicroDEM

Platform: Windows (runs in Linux under WINE)

Last update: 2008

A terrific GIS program for terrain visualization and analysis, but lots of other useful features as well; do a search for MicroDEM on this blog. Has vector editing, analysis, and display functions, but these aren’t as strong as the raster capabilities (but are currently in the process of being improved). New features being added continuously, so check the website for updates to the program and helpfile.

Management Information System (MIST)

Natural Resources Database (NRDB)

Platform: Windows

Last update: 2007

Description

NRDB is a free GIS tool for developing and distributing environmental databases. Its aim is to provide people in developing countries with a powerful yet simple tool to assist in the managing of their own resources.

Database

The Natural Resources Database is a spatial database. As well as storing data of type text or numbers you can also store point, polyline or polygon data.

The data structure of NRDB is hierarchical. This means that, for example, you can represent the administrative structure for your project area and calculate statistics based on this.

NRDB is also a time-series database, all data has a date associated with it. You can therefore observe changes over time in the data.

All data for the NRDB is stored in a single database file which can be redistributed with the software.

The database structure consists of features and attributes. You define these in the Data Dictionary. You can define a structure that meets the needs of your project. NRDB is therefore is applicable to a wide range of environmental / socio-economic projects in developing countries.

Maps

Maps consist of layers. Each layer contains a spatial attribute, e.g. an administrative boundary or the location of a village, and a text or numeric attribute to be used as a label e.g. the name of the village, or the number of households above the poverty threshold.

You can create thematic maps whereby the way the layer is displayed is determined by the values. For example you can make the fill color or symbol size dependent on the value or you can use different colors to indicate houses with and without access to safe water.

You can also change other aspects of the appearance such as the type of the symbol and the positioning of labels.

NRDB includes automatic layout for printing of maps.

NRDB supports UTM and other transverse Mercator projections. UTM projections can be selected simply by clicking on the world map.

Queries

As well as simple selection of features and attributes to display on maps, graphs and reports you can also use queries. These give you more control over what is displayed. With queries you can apply conditions, e.g. only select data for 2002 or display only households that are not formal settlers and are living in makeshift housing.

Queries can also be used for calculating statistics. You can for example count the number of households below the poverty threshold by municipality. You could also normalize this by dividing it by the number of households in each municipality.

In the same way that you can add layers to maps, by selecting values or using queries, you can also produce reports.

You can also output data as histograms, time-series graphs and pie charts.

Digitizing, Import and Export

Data can be encoded directly into the NRDB software. You can also encode data into a spreadsheet and then import it into the NRDB software.

Spatial data can be imported from shapefiles or text files. NRDB also includes a utility for georeferencing image files scanned from paper maps. You can then digitize directly using the NRDB software.

You can export map layers to shape files.

OrbisGIS

Platform: Windows, Linux

Last update: 2007

OrbisGIS is a Geographical Information System (GIS) dedicate to the scientific modeling and simulation. OrbisGIS is develop at IRSTV (Research Institute on Urban Sciences and Technics, CNRS/FR-2488), in the context of the Urban Data Federative Research Project. This project has to do with Urban GIS : tools and methods for the spatial analysis of the urban environment.

Three main axes structure this scientific framework :

  • data acquisition techniques (remote sensing, modeling and simulation, site enquiries…),
  • spatial data processing and representation (storage, modeling, multiscale 3D+t simulations),
  • geographic data sharing.

OrbisGIS is a part of a more global Spatial Data Infrastructure. It is a mandatory component to anyone who needs to process spatial data(create, update, process and model) or visualize them. Based on robust and well-known libraries of the public domain such as JTS (Java Topology Suite) or ImageJ, it provide the ability to join or visualize 2D vector and/or raster data. Those both data types may be stored in a local or remote DataBase Management System or a flat file…

Structure and data model

In OrbisGIS, spatial data are stored in layers. This abstraction has a typical tabular structure that uses rows to store each of the elements of the data source. This structure is close to the JDBC standard, and, as an example, to the storage format of the spatial data used in PostgreSQL/PostGIS.
Concerning rasters, the storage format is the one that is used by ImageJ.

Data access

Data access are realized through two libraries :

  • GDMS (Generic Data-sources Management System) is a semantic layer that has the ability to address and manipulate heterogeneous data. It provides both an API and an extended Spatial SQL,
  • GRAP (GeoRAster Processing) is an abstract layer that provides the ability to process raster data independently from the storage format and from scale. It is a layer that relies on ImageJ.

Visit the GDMS and GRAP pages to obtain more information about supported format.

Quantum GIS

Platform: Windows, Linux, Macintosh

Last update: 2008

Possibly the best basic cross-platform GIS; great support for WMS, WFS and PostGIS. Nice georeferencing plugin, too. Is incorporating support for GRASS functions.

The final part of the series. Part One, Part Two, Part Three. All parts will be regularly updated as more programs come to my attention.

SAGA

Platform: Windows, Linux

Last update: 2007

Can’t say that I’m a big fan of the interface, and some of the modules aren’t fully documented, but boy does this have a lot of functionality. See this post for a more complete listing.

SavGIS

Platform: Windows

Last update: 2008

This GIS seems to have a lot of functionality, but I’ve put off looking at it because the documentation is available only in French. But there is an English version available (Spanish, too), so I’m sure I’ll get around to it one of these days. Here’s a link to Google’s English translation of the features page.

SpringGIS

Platform: Windows, Linux

Last update: 2007?

From Brazil, available in Portuguese, Spanish and English. Lots of English documentation available. Again, haven’t really looked at it in depth, but it does look like it has a fairly large feature set. Biggest disadvantage seems to be the requirement for vector data to be in their unique SPRING format, but translators are available for standard formats like shapefile, MIF, E00 and DBF

Terrain Analysis System

Platform: Windows

Last update: 2003

As a hydrologist and geomorphologist, I was very discouraged by the lack of an affordable software package capable of advanced modeling of catchment processes. TAS is designed to meet the research needs of environmental modellers and managers while being simple enough to use in the classroom. Some geographic information systems (GIS) possess some of the capabilities required by hydrologists, geomorphologists, and other environmental researchers; however, these programs are usually prohibitively expensive. In addition, very few programs compile the number of functions available in TAS in one stand-alone package. Often, such programs rely on other GISs for visualization and standard spatial analysis. TAS can display both raster and vector types of geographic data, and possesses many of the standard spatial analysis function that the environmental modeller requires. The graphical user interface is designed with ease of use in mind. As such, TAS is ideal for lab exercises in introductory to advanced level courses in physical geography, geomorphology, hydrology, environmental science, and watershed management.

TNTLite

Platform: Windows, Macintosh

Last update: 2008

Contains most of the features of MicroImages full TNT program, but has limitations on the total number of objects you can have in a project for the free version:

  • Project Files – No limit on size of .rvc files. No limit on number of objects in a file.
  • Rasters – 314,368 totals cells, maximum dimension of 1024.
    Examples: 1024 x 307, 614 x 512, 307 x 1024.
  • Vectors – 500 polygons, 1500 lines, 1500 points, 1500 labels. (no limit on nodes)
  • CADs – 500 elements, 5 blocks
  • TINs – 1500 nodes
  • Databases – 1500 records per table

TreeSAP

Platform: Windows, Linux, Macintosh

Last update: 2005?

From abstract of article in Progress in Spatial Data Handling: 12th International Symposium on Spatial Data Handling:

Spatial reasoning is a fundamental part of human cognition, playing an important role in structuring our activities and relationships with the physical world. A substantial body of spatial data is now available. In order to make effective use of this large quantity of data, the focus of GIS tools must shift towards helping a user derive relevant, high quality information from the data available. Standard GIS tools have lacked focus in this area, with querying capabilities being limited, and requiring a user to have specialized knowledge in areas such as set theory, or Structured Query Language (SQL). A fundamental issue in standard GIS is that, by relying entirely on numerical methods when working with spatial data, vagueness and imprecision can not be handled. Alternatively, qualitative methods for working with spatial data have been developed to address some key limitations in other standard numerical systems. TreeSap is a GIS application that applies qualitative reasoning, with a strong emphasis on providing a user with powerful and intuitive query support. TreeSap’s query interface is presented, along with visualization strategies that address the issue of conveying complex qualitative information to a user. The notion of a relative feature is introduced as an alternative approach to representing spatial information.
