Agenda
• Geographic data – Maps
• Storing GIS Data on premise (‘locally”)
• Publishing GIS Data as web layers or services
![Page 3: Fundamentals of working with geographic data Miriam Schmidts.](https://reader036.fdocuments.net/reader036/viewer/2022062308/56649e595503460f94b52afe/html5/thumbnails/3.jpg)
• Information about geographic locations - Describes objects in relation to space
• Becomes GIS data when stored in a GIS compatible format- Visualized in GIS maps
• Represented as vector or raster- 2D and 3D
- Geometry
- Attributes
- optionally Time
Geographic Data

URL
• A GIS map is a compilation of layers
• Each layer is a representation of GIS data- Layers reference GIS data
- Stored on premise (“locally’)
- Published as services (web layers)

Storing GIS Data on premise (“locally”)
• File format- Vector: e.g. Shapefiles (.shp)
- Tabular: e.g. Excel (.xlsx)
- Raster/Image: e.g. Geotiff (.tif)
• Geodatabase- Native storage format of ArcGIS
- “Smart” storage container for data- Data Validation, e.g. Domains, Topology
- Advanced data modeling e.g. Networks, Parcel Fabrics
- Single and multi-user geodatabases
• Can convert data formats

Demo: Converting GIS Data formats
• Converting data formats- GPX to geodatabase
- Shapefile to geodatabase
- CAD to geodatabase
- Excel to Table
.shp

Sharing GIS Data as services
• ArcGIS Online/Portal for ArcGIS or ArcGIS Server
… also called publishing
GIS Resources Service type Supported in…
Map document Map ArcGIS Online/Portal + ArcGIS Server
Map document Feature ArcGIS Online/ Portal+ ArcGIS Server
Raster or mosaic dataset Image ArcGIS Server ONLY
Address locator Geocoding ArcGIS Server ONLY
Geoprocessing model Geoprocessing ArcGIS Server ONLY
Geodatabase or geodatabase connection
Geodata ArcGIS Server ONLY

Demo: Sharing GIS Data as services
• Publish a feature service to ArcGIS Online
• Publish an image service to ArcGIS Server
• Make a web map

Summary
• Map layers reference data sources- “Local” datasets
- Web layers (services)
• ArcGIS supports a variety of data storage formats- Geodatabase: native ArcGIS data format (smart container)
- Conversion tools to convert formats into one another
• Publish map and feature services to ArcGIS Online or ArcGIS for Server
• Other types of service: Image, Geocoding, Geoprocessing and Geodata
