ILWIS is an open-source graphical user interface (GUI) for GIS software. It is a versatile tool that lets users view and manipulates various types of maps and data. Unlike most GIS applications, ILWIS does not present a single map window in the main workspace. Instead, users can open multiple layers in separate windows or merge them into a single window. Moreover, ILWIS provides a visible command line where they can run processes and access all available modules.

ILWIS can be embedded into Spatial Data Infrastructures and executed in on-demand and scalable cloud computing environments. ILWIS is used by many users in the remote sensing industry. This makes it easy to integrate it with other applications, such as GIS. However, ILWIS NG is a bit more complicated than its predecessor. Users can use a Python API to build applications.

RIWA GIS Zentrum

RIWA GIS Server enables offline data to be synchronized with online data. The application can also be used on a terminal server. In addition to its GIS server capability, RIWA GIS Server also has a mobile application. Using the app, employees in the field can easily display RIWA GIS data. It can also be used to generate reusable geonotizados. It can even help companies to eliminate the need for paper plans.

RIWA GIS Zentrum is an open-source software application and a rich Internet application. It runs outside of a browser and uses Java as both the client and server software. It was derived from OpenSource-GIS OpenJump. It also uses OpenSource libraries for the graphic client and server. However, the RIWA servers are not OpenSource. Those interested in OpenSource software should consult a RIWA GIS Zentrum representative.

For example, RIWA GIS Zentrum includes the GIS software packages tkgeomap and rmap. Both have been proven to perform a wide variety of GIS tasks. RIWA GIS Zentrum has several modules for creating and analyzing maps. It is possible to create interactive maps, manipulate geographic data, and even view satellite images with the application. These features help scientists understand spatial data in more detail.


An online/offline geographic information system, OpenWebGIS runs on a web browser and a mobile application. It is a free and open-source gis software that has been downloaded by tens of thousands of users. It has also been mentioned in various professional information resources. Now, the team behind OpenWebGIS needs funding to make a qualitative leap in development.

There are two basic types of GIS software available for download: commercial GIS and open source. Open-source GIS is free and available as open-source code for anyone to study.
