Introduction to ArcGIS CORSE 2007 Advanced Track Lesson 1
What’s Happening… • Going to go over the differences between ArcView 3.x and ArcGIS • Introduce a new data container called a GeoDatabase • Then you are going to… • Download an ESRI on-line course • Download the data for that course • Do two of the exercises in that course
Objectives of Ex 1 • Familiarize you with the ESRI on-line courses • Familiarize you with the differences between ArcView 3.x and ArcGIS
The Challenge • You know how to use ArcView 3x • The world is going to ArcGIS, now in version 9.2 • ArcGIS can do everything ArcView 3x could do … • And MUCH MORE! • The price you pay is complexity • Which is not necessarily good from your point of view
Two basic things… • There is no such thing as an Active Theme! • All layers are active unless turned off • When in doubt, Right Click!
In ArcView… • You could… • Add themes to the view • Change symbology of themes • Re-order the themes in the Table of Contents • Carry out many operations on the themes • Select by attribute or location • Overlay themes to make new themes • Etc. • Make maps from themes
And in ArcGIS… • You can do the same things in ArcMap! • Let’s compare the old ArcView user interface with the new ArcMap user interface • But first • ArcMap comes in three license levels ArcView ArcEditor ArcInfo More Power – more $
AV3x User Interface Button Bar Menu Bar Tool Bar Theme View Window Shape-file Table of Contents(TOC) ProjectWindow
ArcGIS in General… • Can do the same kinds of things as ArcView • The interface is different and the terms used are different • Two things to remember • No such thing as the “Active Theme” • When in doubt, Right click
X Tool bars; can be moved around Tool bars; can be moved around Data View Menu Bar Button Bar And in ArcGIS9x Data frame Shape-file Table of Contents(TOC)
Data or Map mode Toolbarsand Extensions Many Tool Bars; RT CLICK CLICK And toolboxes
Add data Zoom in Zoom out Zoom to full Extent Pan Select Feature Basic Tools etc. • Open Toolbox • Open Catalog • FindInfo • Arc Length • Remember the tool tip lower left
The Layout view is where you make maps It is very easy to go back and forth between the Data and Layout views Layout view
Data Management • When you moved data in ArcView3x you had to be sure that you got all the shapefile files • Pain! • So ESRI provided a second software called ArcCatalog • In ArcCatalog you can copy and paste data without having to worry about missing some of the files
In ArcCatalog you can…. • Manage data • Preview data • Geography • Attribute table • View Metadata • When you find the data you want you can just drag it into ArcGIS!!!
Loading data • Data can be • Shapefiles – even ArcView 3 shapes • Various kind of images • Rasters • Coverage (older file type) • And can be either stand-alone data … • Or be in a new container called a GeoDatabase (GDB)
GDB GDB Feature data set (FDS) Feature Class(FC) ShapeFile in a GDB
GDB Feature Data Set Point Line Poly Raster Relate Datafile Text file Shape files Point Line Poly Raster Coverages Point Arc Poly ESRI ArcGIS File Symbols .mxd =.avl
GDB • GDBs are not hard to use • They are hard to build • You can drag them around in Windows Explore with impunity • More and more data is delivered in GDB • Consider GDBs and FDSs to be folders
Views of data in Catalog • The Contents View • Name • Type • Symbol
Views of data in Catalog • Preview of Geometry
Views of data in Catalog • Preview of Attribute table
Views of data in Catalog • Metadata • Description • Spatial data • Projection • Datum • Linear unit • Attributes
The Right Click Trick click
The Right Click Trick click
The Right Click Trick click click click click
Other Advantages of ArcGIS • Project on the fly • That means you don’t have to mess with projections and datums! • But only works if there is a .prj file • Automatic ordering of data in the TOC • Points at top, lines in middle, polys at bottom • Right Clicking! • Properties
Booby Traps • Never, Ever have a space anywhere in a path to ArcGIS data or project!!!! • Use “_” as a spacer not “-” X C:\My Documents\Good-Stuff\.... OK C:\My_Documents\Good_Stuff\....
Exercise 1 • Your have 2 documents • Print out of the course • A document describing how to download and store data • Demo of • accessing ESRI’s virtual campus • Downloading a course • Downloading the data for a course • Doing two exercises • #2 and #3
