This document provides an overview of free and open source GIS software. It discusses what open source GIS is, including the four basic freedoms it provides. It outlines some major open source GIS projects like QGIS, GRASS, PostGIS, GeoServer, and OpenLayers. The document explains why one would use and teach open source GIS, including low costs, community support, and driving innovation. It also addresses some common misconceptions about open source GIS software.
This document provides an introduction to Geographic Information Systems (GIS). It defines GIS as a computer system for capturing, storing, manipulating, analyzing and presenting spatially-referenced data. The document discusses examples of GIS applications, the history of GIS from the 1970s to present, and its use in fields like urban planning, hydrological modeling and the water sector. It also compares open source GIS software like QGIS to proprietary software like ESRI ArcGIS, and reviews some key open source GIS tools including GDAL, Python and OSGeo4W.
New tools are being developed by Czech Living Lab WirelessInfo, which allow users to easily publish their data and metadata as part of a Spatial Data Infrastructure (SDI). The paper describes the design of a Technological Infrastructure on the basis of ISO and OGC Standards and also the implementation of a prototype and first experiences. The solution is designed in distributed system form, which provides the connection to metadata about spatial data and services. This solution tests the principle of catalogue services at both national and international level which could be used in the UN SDI context. A catalogue portal is one of the independent components of GeoHosting complex system for raster and vector spatial data sharing. The catalogue portal provides data source searching on the basis of their metadata records through structure queries. The portal also contains edit functionality for new metadata records creating or editing. The metadata catalogue system corresponds to ISO 19115/19119/19139 standards [1], [2], [3], [4] and provides for cascade searching on the other standardized catalogue systems. The difference is, there exist different other initiatives offering publishing of own content like Google technology or OpenStreet Map, that GeoHosting is based fully on INSPIRE European standards and support establishing of network of distributed servers.

WORLDMAP: A SPATIAL INFRASTRUCTURE TO SUPPORT TEACHING AND RESEARCH (BROWN BA...Micah Altman
The WorldMap platform http://worldmap.harvard.edu is the largest open source collaborative mapping system in the world, with over 13,000 map layers contributed by thousands of users from Harvard and around the world. Researchers may upload large spatial datasets to the system, create data-driven visualizations, edit data, and control access. Users may keep their data private, share it in groups, or publish to the world.
The user base is interdisciplinary, including scholars from the humanities, social sciences, sciences, public health, design, planning, etc. All are able to access, view, and use one another’s data, either online, via map services, or by downloading.
Current work is underway to create and maintain a global registry of map services and take us a step closer to one-stop-access for public geospatial data. Another project is working on tools to support the visualization of spatial datasets with over a billion features. Current collaborations are underway with groups inside Harvard, such as Dataverse, HarvardX, and various departments, and with groups outside Harvard, such as Cornell University and the University of Pennsylvania. Major additional contributors to the underlying source code include the WorldBank, the U.S. State Department, and the United Nations.
The source code for the WorldMap platform is available on GitHub https://github.com/cga-harvard/cga-worldmap.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

2. • Free software means the users have the freedom to run, copy, distribute, study, change and
improve the software.
• Open source software is defined as software that has the source code freely available and is
licensed so that it can be freely distributed and modified as long as appropriate credit is
provided to the developers. There are several licensing options for open source software but all
of them follow these basic rules. More information about open source software is available at
the Open Source Initiative web page (http://www.opensource.org/).
• Free and open-source software (FOSS) is software that can be classified as both free
software and open-source software. That is, anyone is freely licensed to use, copy, study, and
change the software in any way, and the source code is openly shared so that people are
encouraged to voluntarily improve the design of the software. This is in contrast to proprietary
software, where the software is under restrictive copyright and the source code is usually
hidden from the users.
