The ArcGIS Tutorial
2
The Exercises

• Intro to ArcGIS
• Building a Base Map
• Projections and Coordinate Systems
• NHD, Hydro network etc.
• DEMs, Watershed and Stream
• Time Series

3
Building the Base Map

• A Review for the most part
• Building a GDB
• Downloading and importing data
• Selection of watersheds join
• Relationship class
• Creating and projecting a point class
• Adding attributes thru editing table
• Creating chart
• Creating layouts

Did you get it to work?
That was new for me
4
Experiences

• For me it was a review for the most part
• But I found it easy to make mistakes if I did not
  read ahead
• I had it reinforced that when you create a
  feature class in ArcCatalog and then open the
  project the new one wont be there until you add
  it to the mxd

5
Your Experiences?
6
4 NHD, Hydro network

• Has three parts
• Intro to map Hydrography data features
• And how to symbolize
• Use Network tools to
• Build a network of river and coastline features
• Assign SINKS and SET FLOW DIRECTIONS
• Perform TRACES
• Application of the hydro schema to create an
  ArcHydro Framework dataset and use of hydro tools

7
Installs ArcHydro

• The data download includes everything needed

8
Installs MSXML

• The data download includes everything needed
  this too.

9
But

• It is not necessary, as near as I can tell, until
  later in the exercise

10
GIS New Stuff

• This is a long one! 41 pages!
• Almost all new stuff
• Building networks applicable to many things
  other than hydrology
• Pipes, Power, internet cabling, etc.
• Thus useful in a general sense
• Using ArcGIS Tools no harm in that
• Using ArcHydro Tools Not useful for all of you
  but worth doing anyway

11
Schema

• This is new and worth doing since schemas are
  common in data models
• What is it?
• A blank GeoDatabase that contains assigned
  attribute names for the ArcHydro feature classes
  and relationships between them
• The schema is applied to an existing dataset
• Need the schema wizard in ArcCatalog
• Lesson shows how to add if not there

12
Schema 2

• You MIGHT be able to do in the Cluster (Ill try
  after class)
• You can do it 414 (will be already done for you)
• You CAN do this in the mapping sciences lab (and
  you will be able to get 24/7 access by getting
  key when lab closed campus police)

AND, Wonder of wonders, you can now write to your
account in the MSL!
13
5 DEMs

• Problem 1 is that none of the graphics will print
  get big black blobs
• You will have to do with the html live on your
  computer screen
• 39 pager dealing with the extraction of
  hydrologic features from DEMs
• Looks interesting

14
6 Time series

• Get to use 3-D analyst so that is plus
• Covers getting time series data as in 2 and
• Displaying and graphing in Excel
• Using Nexrad (Weather radar) and displaying
  precipitation
• Using that data to model accumulation of water in
  the watersheds ( NEAT! )
• The exercise looks interesting and not too hard
  or time consuming.
