2. ArcCatalog • Manage Files and folders • Create new shapefiles and geodatabases • Preview files • View metadata in format of choice • create metadata so your data can be understood and shared with others • Save metadata files as .xml, .txt., .html or .sgml

3. ArcGlobe • View the world as a globe • 3D effects • Animated fly- throughs

4. Terminology • Georeference: Aligning geographic data to a known coordinate system so it can be viewed, queried, and analyzed with other geographic data. Georeferencing may involve shifting, rotating, scaling, skewing, and in some cases warping or rubber sheeting the data. • Geocode: associating a table of address data with a gis street file to create a point gis layer

5. Shapefile (.shp) • A vector data storage format for storing the location, shape, and attributes of geographic features. A shapefile is stored in a set of related files (.shp, .dbf, .shx…) and contains one feature class (point, line or polygon.

6. Geodatabase • relational databases that contain geographic information (stored with the extension .mdb – same as MS Access). • Can contain points, lines, polygons, tables, annotation and rasters • Enables topology: a set of relationships that defines how the features in one or more feature classes share geometry—for example, in an underground network it is important to know which pipes are on top or bottom and if they are connected; census tracts cannot cross each other nor county lines. • Data in a geodatabase must all be in the same coordinate system and share a common geographic area • Must have ArcEditor or ArcInfo license to create and edit

7. Learn about Geodatabases • ESRI virtual campus classes (http://libraries.mit.edu/gis/teach/esrivc.html) • Basics of the Geodatabase Model • Creating and Editing Geodatabase Features • Creating and Editing Geodatabase Topology • Creating and Editing Linearly Referenced Features • Creating, Editing, and Managing Geodatabases • Migrating Coverages into the Geodatabase • Working with Geodatabase Subtypes and Domains • Working with Map Topology in ArcGIS • Library resources • http://libraries.mit.edu/barton • Title words: geodatabase • ESRI online support • http://support.esri.com/

8. CAD in ArcGIS • Readable and writeable CAD formats: • AutoCAD drawing files (.dwg) and partial drawing interchange files (.dxf) • MicroStation design files (.dgn)

9. CAD in ArcGIS

10. Add data to ArcMap from the Internet http://www.geographynetwork.com/

11. Today’s Exercise • Georeferencing: Aligning geographic data to a known coordinate system so it can be viewed, queried, and analyzed with other geographic data. Georeferencing may involve shifting, rotating, scaling, skewing, and in some cases warping or rubber sheeting the data. • Adding tabular data • Geocoding: associating a table of address data with a gis street file to create a point gis layer • Adding xy data • Spatial Join, Dissolve, and Field Calculation to determine the density of schools per neighborhood • Creating and running a model – automate tasks, save the processes run on your datasets, etc • Editing shapefiles • Create a 3D model in ArcScene
