Editor's Notes
- The extension is an optional extension to ArcGIS and adds additional functionality for reading over 100 GIS, CAD, and database formatsExtensionbased on Safe Software's FME technology and includes the FME Workbench application.The extension allows for data to be read directly from source and also includes quick import and export tools.Within the workbench application you can build complex spatial etltoolss.The extension is fully integrated with standard geoprocessing tools and model builder.
- Work directly with more than 100 data formats without the need to convert between formats. GML, XML, WFS, Autodesk, DWG/DXF, MicroStation Design, MapInfo, MID/MIF and TAB, Oracle and Oracle Spatial, and Intergraph GeoMedia WarehouseOnce the Extension is activated, you can see supported data in ArcCatalog And you can use the data the same way you would use esri datasets, for viewing, analysis and mapping
- The extension installs a data interoperability toolbox in ArcToolbox and includes Quick Import and quick export tools.The quick import tool loads directly from source into a personal or file geodatabase, this is very handy if you don’t require any data manipulation to be doneThe quick export tool can export to over 75 industry formats. Both tools can be run as stand alone or as part of a geoprocessing model or script to script tool.Data interoperability tool is fully integrated with geoprocessing tools, meaning you can keep your source data in their industry format and simply use them as input in any geoprocessing tools or even model builder.This model uses a MapInfo MIF file as input to a buffer operationAn ESRI shapefile is generated from the buffer operation, which is then output to three different formats – GML, file geodatabase and GeoMedia
- DemoLook at ESRI data in ArcCatalogEnable Data interop extension – refresh – can now see new data formats, looks like any feature class. Can be added to map, look at attribute.Look at interoperability extensions – Not all data immediately visible – double click to add. Select format, now you can see data and once again all standard map functions supportedCan use within arcmap, Symbolise, select, buffer??
- Extract the data from a source system. Transform the data into the format and data model required by the target system. Load the data into the target systemSpatial ETL simply means you can EXTRACT, TRANSFORM and LOAD Spatial data – often referred to as For Example:Enterprise organizations with multiple database GIS technologies
- Safe Software's FME Workbench application is included with the ArcGIS Data Interoperability extension. It provides a visual diagramming environment with more than 240 transformers [PDF] that enable you to transform both geographic and attribute information.Attribute transformers would be something like joins, Renaming or even creating attributesGeometric transformers may include building geometry (lines from points, polygons from lines), filter by geometry, coordinate setter etc.
- Give an overview of WorkbenchOpen existing ETL toolShow Navigator Pane – Source, Transformers, bookmarksShow Transformer Gallery – Categories, Search, Help, FavouritesWorkspace Canvas – reads from left to right Readers, transformers, writers – can add readers and writers from File Menu
- Some commonly used Transformers:To select a subset of you data you can use the attributefilter (select all records where value is more than 25000) geometry filter (popular with CAD) – split data into poin, line, polygon, annotationTranslation – valuemapper (attributevaluemapper) you want to change attributes from 1, 2, 3 to a, b, cConstruct Geometries – areabuilderManipulate attributes – join, neighborfinder (can find annotation closest to feature and assign it as attribute)
- Look at data in ArcCatalog – familirise with data, show properties are drawn as blocks and fence lines. WE want properties to be individual polygons and the property number should be assigned as an attribute.(if time) we also want to join a dbf file of the owners to the propertyCreate ETL tool – wizard – go through steps, level names, etcTransformers used
- Q: When do I use workbench over Quick import and Export tool?A: Quick import/export tool performs a straight translation without any manipulation. Workbench gives you the ability to manipulate your data Q: What is the difference between workbench and model builder?A: They are both graphical authoring environments, but workbench allows you to manipulate data at feature level, where model builder manipulates data at feature class (dataset) level. You can also have a spatial ETL tool within model builder.
