1. Unit Eleven: Develop New Data In this unit… ► Overview ► Using ArcGIS Components ► On-Screen Digitizing

2. Unit Twelve – Develop New Data 2 Overview Types of new data creation you may encounter: ► New Data Frame (?) ► Data imported from another format ► Fields and data added to tables ► New Feature Data from  GPS  Digitizing  Sensing positional data in tables 4 4 7 Sorry, not data Did it! As needed… This Unit

3. Unit Twelve – Develop New Data 3 Using ArcGIS Components ArcGIS components work separately or together:  Drag & drop from ArcCatalog to add data  Launch components with icons  Convert/import data with ArcToolbox and add to map document in ArcMap  Preview data in ArcCatalog to confirm file content before adding to ArcMap

4. Unit Twelve – Develop New Data 4 On-Screen Digitizing Digitizing factors:  One Data Frame editable at a time  Reference feature(s) normally required  ArcCatalog required to create an empty file  Digitizing Done in ArcMap Data View  Advanced editing tools available* *(not addressed in this workshop)

6. Unit Twelve – Develop New Data 6 On-Screen Digitizing Orientation: For every feature you may want to edit… there is a corresponding “sketch” - change the sketch to alter the feature.For every feature you may want to edit… there is a corresponding “sketch” - change the sketch to alter the feature. Q: When is feature a “sketch”? A: When you can see the vertices… or whenever the feature is being editedQ: When is feature a “sketch”? A: When you can see the vertices… or whenever the feature is being edited Sometimes, a new sketch will be used to modify the sketch of another featureSometimes, a new sketch will be used to modify the sketch of another feature

7. Unit Twelve – Develop New Data 7 On-Screen Digitizing Orientation: 2. Pick the task 4. ID the Target layer (only layers in the active Data Frame are listed) 3. Select a tool 1. Start editing in the active Data Frame

8. Unit Twelve – Develop New Data 8 On-Screen Digitizing Snapping  An orderly and reliable method for connecting: ► End points ► Vertices (nodes) ► Mid-points ► Edges  Interactive and context-driven ► Right-click the feature you would snap to

9. Unit Twelve – Develop New Data 9 On-Screen Digitizing Tips:  Right-click menu for ► Interactive snapping ► Ending part ► Ending feature… etc.  Double-click to end part  Zoom and Pan tools active and independent  Select new drawing tools mid-feature
