Learning more of the basics for ArcView 3.3
Using ArcView Part 22
Areas to be covered today
Saving a project – how to and how not to Image and Feature themes (data types) Adding a Theme Scale – how to insure it appears on your final map Changing colors with the Palette Manager – especially
translucent colors Minimum Requirements for a Map Adding Name, Date and data source to your map Making a jpeg from a layout Proclib – what is it and what is required Additional Icons in ArcView
Using ArcView Part 23
Saving a Project
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 24
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 work2. In AcrView Click on the File menu drag down to Save As and click3. Click on the drop-down list for the Save In field4. 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
boxremove the default name that was given and change it to your new file name7. Click the Save button.8. The new file name should appear in the title bar of your file or ArcView project window. Originator: Lauren SeabyProcedure Date: 10-18-00Updated: p. buckley, 10-14-08
Using ArcView Part 25
First set drive
Second choose folder
Third create filename
Using ArcView Part 26
Saving a Project
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
Using ArcView Part 27
Feature and Image data
Our example using the simple exercise data set should well illustrate this
Also check-out Some Definitions on the Course Web Page
Feature data Image data
Using ArcView Part 28
First How To -- Definition Building
Divide text or powerpoint material into bullets Rank them by order of importance Translate these points in sentence(s) using
your own words. Insert examples in the definition
Using ArcView Part 29
Feature Data
Using ArcView Part 210
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.
Feature Data: Entity & Attribute
Using ArcView Part 211Note one Attribute (Descriptive Information) line or record for each Entity (Province)
Adding Image Data
Using ArcView Part 212
Change the Data Source Type
Using ArcView Part 213
Image Data
Note there are no Attribute Tables Available with Image Data
Using ArcView Part 214
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.
Using ArcView Part 215
Now you do it
Take a moment to build a definition for each feature and image data
Using ArcView Part 216
Adding a Theme to a View
Be sure to choose between feature and image data
Using ArcView Part 217
AddTheme
When adding a theme be sure to choose between feature (usually default) and image data
Using ArcView Part 218
Scale
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
Using ArcView Part 219
Setting Scale
From the Menus open
•View/Properties
•Then set map units to correct map units
•Map units are the coordinate system units in which the data is electronically stored like feet in State Plane
Coordinate system units
Using ArcView Part 220
Setting Scale
Here the Mapping units are metric (meters)
Electronically stored units
But when measuring around town in Bellingham the Distant units have been set to miles
Using ArcView Part 221
Selecting the measurement tool
Using Scale to Measure
Using ArcView Part 222
Measuring in Miles across Bellingham Bay
Measurement in miles
Mapping units (coordinate units) in meters
Using ArcView Part 223
Using Scale
Now the scale bar in the final Layout Map can be used
Using ArcView Part 224
Translucent Colors
Choose the theme you wish to work with Know the difference between foreground and
background colors Know what fills are Make your choices
Using ArcView Part 225
Translucent Colors
This is left as on exercise for you to figure out – Take GOOD notes in class
Using ArcView Part 226
Minimum Requirements for a Map
See the course web page
Also realize that this is a changing answer
However in my class use my requirements
Using ArcView Part 227
Adding metadata… to a map
Take some notes on the icons we use Also see PowerPoint notes from last week
Making a jpeg from your Layout
Choose File/Export
Using ArcView Part 228
Making a jpeg from your Layout
In order set the
1. Drive
2. Folder
3. Format (jpeg)
4. File name
Using ArcView Part 229
Using ArcView Part 230
ProcLib
Procedure Library – crib notes to remind you and your co-workers how to accomplish a given task
See my minimum requirements and examples on course Web Page
Using ArcView Part 231
Additional Icons
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
