Esri UC 2014 | Technical Workshop | Geograpic Data (Geodata) Information about geographic locations that is stored in a format that can be used with a geographic information system (GIS). Can be stored in a - Geodatabase - Raster image - Tabular data such as dbf tables or Excel spreadsheets - Shapefiles - Other, e.g. - Computer aided design formats (AutoCAD DWG or Microstation DGN files) - GPS Exchange format (GPX) Fundamentals of Working with Geographic Data
6
Esri UC 2014 | Technical Workshop | GIS Web Services A GIS resource made available on the web - Map layers – Map Service, Feature Service - Feature access makes a feature service - 3D layers – Globe eservices - Address locators – Geocode service - Geodatabase connections – Geodata service Each Web service has a distinct HTTP location (URL) Can be hosted - On-premise ArcGIS Server server - ArcGIS Online, - Portal for ArcGIS Fundamentals of Working with Geographic Data ArcGIS
7
Esri UC 2014 | Technical Workshop | Geodatabase Native storage format of ArcGIS “Smart” storage container for data - Stores data as - Feature Classes / Feature datasets - Raster Datasets /Mosaic Datasets - Tables - Validates data through - Topologies - Attribute domains - Subtypes - Networks - Parcel Fabrics - Many more… Fundamentals of Working with Geographic Data
8
Esri UC 2014 | Technical Workshop | Demo Explore the source data of a map - View common geographic data storage formats in ArcGIS Fundamentals of Working with Geographic Data
9
Esri UC 2014 | Technical Workshop | Data Conversion Editable data formats in ArcGIS - Geodatabase feature classes - Shapefiles - dBase tables - Tables in any supported DBMS (e.g. SQL Server or Oracle tables) Read only - CAD datasets (e.g. DWG or DGN) - MS Access tables - Excel tables - Text, ASCII, or comma-separated value (CSV) files - Many more.. Fundamentals of Working with Geographic Data
10
Esri UC 2014 | Technical Workshop | Demo Converting data formats - GPX to geodatabase - CAD to geodatabase - Table to Excel - CSV table of addresses to point feature class Fundamentals of Working with Geographic Data
11
Esri UC 2014 | Technical Workshop | Summary Each map layer references a source dataset - Source data can be feature classes (collections of points, lines, or poygons) or raster/image data ArcGIS supports a variety of data storage formats - Geodatabase and shapefiles are editable formats - There are many conversion tools to convert formats into one another - Tables of addresses / XY coordinates can easily be converted to points on the map The geodatabase is a “smart” storage format that allows for data validation and modeling Fundamentals of Working with Geographic Data
