  1. ArcGIS Programs & user interface

  2. Overview • ArcGIS is composed of two programs • ArcMap • ArcCatalog esf Laboratory for Applied GIS

  3. Overview • ArcGIS is composed of two Applications • ArcCatalog • The data management and step 1 of data creation • ArcMap • The data creation (step 2),assembly, analysis, and mapping application esf Laboratory for Applied GIS

  4. Increasing tools and options BUT…Booby Trap • ArcGIS is an encapsulation of ArcMap and ArcCatalog • ArcGIS comes in 3 license levels – from low power to high “power” • ArcView – the basic software • ArcEdit • ArcInfo – the most powerful software Student esf Laboratory for Applied GIS

  7. Data Management

  8. How to manage YOUR data • Problem: You can’t store data on the public machines – they get wiped clean every day or so. • You really have to work with data in the folder C:/Workspace • And so does everyone else! • So… esf Laboratory for Applied GIS

  9. So… • Keep your data on a memory stick (flash memory) • In a workspace called “yourname”* • When you fire up a campus machine • 1- erase everything in C:/workspace • 2- copy Yourname into workspace • When you are done copy (drag) yourname back into your memory stick. • If you are a nice person you will delete your “yourname” folder from C:/workspace! * “yourname” is a stand-in for your name. Example: if you are Eustis B Nifkin then you might call your personal workspace EUSTIS esf Laboratory for Applied GIS

  10. On your flash memory stick On one of the ESF computer cluster machines For Example COPY or Drag esf Laboratory for Applied GIS

  11. There is more to this… • A .mxd file (your map document) does NOT contain ANY data! • Only paths to the data • So, for example, if you were to move the data files the .mxd would not be able to find the data. • This is a booby trap too. • However... esf Laboratory for Applied GIS

  12. However… • You can set up your .mxd so that as long as the data and the .mxd are in the same relative relationship in a data tree then you don’t have to worry about this problem • So if you flash data structure is Z:\Eustis\data and on a cluster ‘puter it is C:\Workspace\Eustis\data every thing will work just fine!  esf Laboratory for Applied GIS

  13. So how to you do that? esf Laboratory for Applied GIS

  14. You need check that this is the default way to save data every time you open ArcMap or a .mxd!!!!!! DEMO esf Laboratory for Applied GIS

  15. Map Lab • I asked a poor question on the map exercise lab. • It was supposed to have you calculate the scale of an enlarged map. • But it was a little confusing. esf Laboratory for Applied GIS

  16. Computing Scale • If you know the distance between any two points on a map you can calculate the map’s scale Scale = 1 unit one the map / number of units on the ground If the distance between 2 points is scaled off or known to be2 miles and the distance between the points on the map is 10 inches Then the scale is (10 inches)/(2 miles) or 5in/1mi= 5/(5280 *12)in = 5in/5268in = 1/1053.6 esf Laboratory for Applied GIS

  17. Booby Trap 1 WARNING Never, ever create a path to ArcGIS data that has spaces in it. If you do ArcGIS will not find the data! esf Laboratory for Applied GIS

  18. Booby Trap 2 Save the .mxd often! ArcGIS has a habit of crashing at the most critical part of a project! When doing something that you do not want to lose it is a good idea to increment saves. First save: mystuff1, second save mystuff2,….mystuffn esf Laboratory for Applied GIS
