The world we live in is increasingly challenged. Changes in population, over-consumption, and sustainability—these are some of the things we can begin to understand with GIS and data. Statistics based on data collection, analysis, and interpretation need a geographical background to understand it more, and thus to make a more accurate decision. Where statistics alone are not relevant without being associated with a specific place. The Palestinian Central Bureau of Statistics has embarked on a strong experience in the field of GIS, starting with collecting and storing statistical data in geodatabases, representing it on statistical maps, and disseminating it through interactive platforms and open data sites. This made it easier for researchers and decision-makers in Palestine to easily access statistical data and analyze it based on spatial coordinates and infographics provided by the GIS Web-based platforms and portals. Through the use of Esri's ArcGIS Technologies, which was able to develop desktop and web-based software packages such as ArcMap, Arc Editor, Arc Catalog, and finally ArcGIS pro and ArcGIS online, to support the journey of collecting, displaying, visualizing, and disseminating statistical data in an understandable manner for all categories that target this type of data. Speaking of the data collection stage (collecting statistical data based on spatial points using GPS); data collection systems have been developed through mobile cellular phones connected to the internet, which in turn send the data from filed work to pre-defined geospatial databases through the previously mentioned software package. Whereas, it is advisable to stream all numerical data in the data acquisition to the geodatabase. This will result in more reliable statistics, reduce the source of error, and save time. Thus ensuring high data quality and performance which in turn will lead to a more accurate decision. The stage of statistical data collection is followed by the stage of storing this data in a relational database based on geospatial coordinates. Named geo-databases which include a set of tables that contain spatial fields, and descriptive fields (non-spatial that includes statistical data). Esri's programs such as ArcMap and ArcPro provide tools to display these databases, modify them, perform statistical operations on their fields, and represent the statistical data on the map through multiple techniques such as Symbologies and 3D Cartograms. Esri's technologies have gone beyond the presentation of data to dissemination through web-based technology called ArcGIS Online, which in turn will make statistical data open and available to everyone and anywhere in the world, in addition to providing many tools for creative modeling in data presentation, and allowing the user to download geospatial databases with the extension that suits them directly and without an intermediary. In this paper, a lengthy presentation will be made about the effectiveness of using GIS applications in serving statistical data in Palestinian Central Bureau of Statistics projects, and the outputs that were produced as data collection techniques, geo-databases, statistical atlases, interactive maps platforms and open data sites to provide high-quality data, in an understandable manner to decision-makers.
