This GIS Data Model and the NG9-1-1 system rely on standardized, accurate, and up-to-date GIS data. This document updates previous GIS Data Models for use in the NG9-1-1 system while remaining backwards compatible with existing Enhanced 9-1-1 (E9-1-1) GIS data needs.

A closer link between data modelling and spatial data offers an excellent growth medium for built environment projects and digital asset management solutions.

The GIS community is invited now to start thinking about how a template design might look for own organisation and industry, how we would document the various parts of the data model and how we could share tools and methods across user communities. The spartial Reference: describes the measurement system for finding the extent of a model of the Earth. Sourcing GIS Data. Here are a few places where you can get the best free GIS data: Esri: The Esri Open Data Hub is a goldmine of free data. As of 2020, this GIS website provides its users with over 250,000 datasets from over 5000 organizations.

Once you find a relevant data model, you can download a geodatabase template from the site that you can use to jump-start your design. You can build a test geodatabase, load some data into it, then test and refine the design for use within your GIS. Steps in using an ArcGIS data model as the basis for your design

Data modelsare a crucial concept for GIS users to understand. Data models describe how geographic data will be represented and stored.

The aim is to analyse GIS data models, stored in UML class diagrams, for scale-free and small-world properties. Moreover, a robustness analysis is to be carried
