What is a SDI?
SDI is a collaborative framework for various aspects of geospatial data and tools. Storage
Access
Metadata,
Querying, Display of spatial data
Access to spatial data services
Data integrity and organization
Reducing redundancy.

Data Storing
Create, maintain and store spatial data
Shapefiles, excel tables, databases (such as PostGIS), WMS layers
![Page 5: Exploring Spatial Data Infrastructure in an Open Source World Jacqueline Lowe UNC-Asheville National Environmental Modeling and Analysis Center Jacqueline.](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f175503460f94c2e1d8/html5/thumbnails/5.jpg)
Data Access
Different Users and different formats
Viewing, querying maps
![Page 6: Exploring Spatial Data Infrastructure in an Open Source World Jacqueline Lowe UNC-Asheville National Environmental Modeling and Analysis Center Jacqueline.](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f175503460f94c2e1d8/html5/thumbnails/6.jpg)
Demonstrating the Use and Concepts of a SDI
GeoNodeFree and Open Source!
Version 2.4
Configured on Ubuntu operating system
Works with GeoServer and PostGIS
Other SDIs, such as GeoNetwork

USE CASE EXAMPLE
Lots of data in different formats, vector and raster
Different scales including National, State, County
Different types of users, some proficient in GIS, others are not
![Page 8: Exploring Spatial Data Infrastructure in an Open Source World Jacqueline Lowe UNC-Asheville National Environmental Modeling and Analysis Center Jacqueline.](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f175503460f94c2e1d8/html5/thumbnails/8.jpg)
Uploading Layers to Catalog
Different data formats, raster, shapefile, other vector
Control over user permissions

Styling Layers
Not quite as extensive as some other mapping programs (Desktop GIS).
Shapes, add labels, and adjust the look of the points based on attribute values and scale.

Managing Metadata
Keywords are custom “tags”
Categories are based on metadata Standards
Both provide ways of standardizing the way data is accessed and organized

Automated Publishing to GeoServer
You can now access and share WMS layers with Geoserver.
![Page 12: Exploring Spatial Data Infrastructure in an Open Source World Jacqueline Lowe UNC-Asheville National Environmental Modeling and Analysis Center Jacqueline.](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f175503460f94c2e1d8/html5/thumbnails/12.jpg)
PostGIS Database
Layers are automatically added to PostGIS database
Ability to connect GeoServer to other data sources as well.

Viewing and Creating Maps in Mapviewer
In the Mapviewer, you can add multiple layers, (your own or selected)
Publish and save completed map
Access WMS
