  1. FOR357/557 Module 1 Highlights Learning your way around

  2. Course Stuff… • There are now 45 of you! • So I have to change some things • Each week when you hand in • Quiz from module • Exercise I assign • You will add a reflection page for the WEEK • You will put The week #, your name, Your Class (357 or 557) on the back, upper right of the reflection page. • This does not apply to this week.

  3. MORE • There is a fairness question – • Some have lab Tuesday and some Friday • Yet things have to be turned in on Tuesday • BUT: since labs are help sessions and since usually they are only 20% full (after the first couple of weeks) anyone can go to any lab. • SO DON’T WAIT TO FRIDAY TO WORK – START EARLY • Tuesday night stays the turn in day (Actually Wednesday AM @ 8:00 is when I take things out of the box outside my office.

  4. questions ?

  5. OK, back to technical stuff

  6. Table of Contents (TOC)

  7. Data Frame Data Frames Data Containers…

  8. Layout View;Active Button

  9. Tool Bars You can move them around. In fact, you can move them right off the ArcMap Window

  10. Data Views • Data View • Layout View • Attribute Data View

  11. Data View

  12. Layout View

  13. Attribute View (Hotels)

  14. TOC – 3 flavors • Display Tab • Allows you to manipulate the data • And change layer position by dragging This is usually where youwant to be!

  15. TOC – 3 flavors • Selection Tab • Shows which layers are selectable • And you can change that right there By default ALL are selectable andthat can be a booby trap that canget you into trouble in many ways!

  16. TOC – 3 flavors • Source Tab • Allows you to manipulate the data • Shows path to data • Cannot change layer order

  17. . M?? things • In the previous slide the San Diego data was stored in a GeoDatabase • I can tell this from the symbol and from the extension (mdb) on the file “folder” that contains the layers • The .mdb folder = a GeoDatabase • The other .M thing is the .mxd or map document

  18. GeoDatabase? An object-oriented data model introduced by ESRI that represents geographic features and attributes as objects and the relationships between objects but is hosted inside a relational database management system. A geodatabase can store objects, such as feature classes, feature datasets, nonspatial tables, and relationship classes.

  19. GeoDatabase? An object-oriented data model introduced by ESRI that represents geographic features and attributes as objects and the relationships between objects but is hosted inside a relational database management system. A geodatabase can store objects, such as feature classes, feature datasets, nonspatial tables, and relationship classes. All in one chunk!

  20. Identification • There are several ways of identifying features (and this is related to selecting) • Use the Drawing toolbar selection tool to display a “map tip” if one exists • Use the Identify tool to display the record of data for that object • Select the feature and look in the attribute table for info

  21. Selection • Selection is a way of focusing the system’s attention on a specific feature (object) or set of features • There are several ways of selecting • Use the selection toolThe feature will get a strange aqua color or outline. The record in the attribute table will be colored aqua also • You can shift-Click to select a number of features • You can select a record in the attribute table and it will also be selected in the dataview

  22. More Selection • Under the Selection menu there are a number of options • Select by location (select features from one or more layers based their spatial relation to features in another layer) • Select by Attribute (select features based on data in the attribute database)

  23. Adding Data • Directly from ArcMap • Drag from ArcCatalog

  24. ArcCatalog • Is a very handy application • In Exercise 1a you will see that a shapefile is composed of 3-~8 files • And thus is hard to move because you always leave something behnid • In ArcCatalog, however, it appears as one file and you can move, rename, etc much easier

  25. ArcCatalog (cont) • Booby trap – sometimes if you are working with data in ArcCatalog you cannot add it to a map because Catalog is using it • Solution – close ArcCatalog • Point – this is not a ESRI thing but is due to Windows not liking two apps working with the same data at the same time!

  26. ArcCatalog (more yet) • ArcCatalog is very handy because you can preview data before you load it into ArcMap • You can look at • Contents (name, Type, Symbol • Preview • Geographic data • Table data • Metadata

  27. Avoid Booby Trap • You should always manage your data in ArcCatalog and NOT in Windows Explorer. • In ArcCatalog shape files are represented by one file • In Windows Explorer shape files are represented by 3 or more files • Too easy to miss one if moving files around!

  28. Questions? ?
