A project file DOES NOT SAVE DATA
A project file saves a path to data
Thus when you resume work on a project the
path (location must be the same as in the
past)
Using ArcView Part 2
Saving a Project: Proclib
Title: Using the Save As Feature for a Project File (.apr)
·
Purpose: To save files in the place you want, in this case to a C:/Temp/yourfolder file.
Procedure:
1.
In the U:/ drive or your thumb drive directory create a new folder with a name reflecting your work
2.
In AcrView Click on the File menu drag down to Save As and click
3.
Click on the drop-down list for the Save In field
4.
Select the appropriate drive, in this case drive U or F or such in the pick window.
5.
Scroll down and double Click on the folder you have created above to open it.
6.
Now, and not earlier, name the project something meaningful by clicking in the File Name title
boxremove the default name that was given and change it to your new file name
7.
Click the Save button.
8.
The new file name should appear in the title bar of your file or ArcView project window.

I suggest getting into the practice of saving
your project on either you U: drive or thumb
drive. Later in the quarter we will talk about
saving on the C: drive

Feature Data

Using ArcView Part 2
Feature Data – ESRI Definition
In ArcView, features are stored as vector data and their attributes
are stored in tables known as attribute tables. Each class of
features is stored in a shapefile and has its own attribute
table. Attribute tables contain one record for each feature of
that class in the coverage.
 Points: Points represent features found at discrete locations,
such as telephone poles, wells and mountain peaks.
 Arcs: Arcs represent linear features such as streams, streets
and contours.
 Polygons: Polygons represent areas enclosed by specific
boundaries, such as countries, states, land parcels and soil
types.

Image data – ESRI Definition
(my highlights)
An image is a graphic representation or description of an object that is typically
produced by an optical or electronic device. Some common examples of
image data include remotely sensed data, such as satellite data, scanned
data, and photographs.
 Image data is a form of raster data where each grid-cell, or pixel, has a
certain value depending on how the image was captured and what it
represents. For example, if the image is a remotely sensed satellite image,
each pixel represents light energy reflected from a portion of the Earth's
surface. If, however, the image is a scanned document, each pixel represents
a brightness value associated with a particular point on the document.
 To change the way an image looks and to derive additional information from
an image you can edit an image's legend. (Aside: but this is very limited)
 Images are often used as the background to views, with spatial data being
drawn on top of them. Themes representing images are therefore normally
moved to the bottom of the view's Table of Contents, so that they are drawn
on the view first.
 The main difference between image data and feature-based spatial data is
that images do not contain attribute data about the features they show.

Now you do it

Take a moment to build a definition for each
feature and image data
Using ArcView Part 2
Adding a Theme to a View

16
Be sure to choose between feature and
image data
Using ArcView Part 2
When adding a theme be sure to choose
between feature (usually default) and image
data

Must know the scale/Coordinate System at which
the data was electronically stored
The most common Coordinate System for ESRI
is lat/long
The most common in the US in governments is
State Plane
The most common internationally is UTM
Know mapping units and choose measurement
units

Take good notes then review them and make
them better
Wherever you work you will be doing this the
rest of your life
Good skills at this will lower you blood
pressure and pay big bucks
