Using Arc/View pt. 12

1. Starting Arc Map

Accept Default of Empty Map

This window is called the Table of Contents (TOC)Where your data layers are accessed

This is the Data View Window where you cartographic results will appear

Roles of Table of Contents

Top Tool Bar & Menu Tabs

Middle Tool Bar

Bottom Tool Bar

Adding Data to your GIS project: With Layers (Data Frame) highlighted click on Black Cross to Add Data

This window is called the Table of Contents (TOC)Where your data layers are accessed

This is the Data View Window where you cartographic results will appear

We will start with a very, very simple data set on the J drive under j:/Saldata/Envs221 /Data GIS Assignment

After navigating to J:/saldata/Envs221/Data GIS assignment using your Shift Key and mouse highlight the following three data layers (also called shape files):

cities, fishhab, & hydr100k Finally hit the Add button

Accept the defaults and the data layers will appear in the Table of Contents (TOC)

To activate these in your View window you must click the check boxes to turn on the data, the colors that result are random and arbitrary

Now we need to learn how to zoom in on the image and change the colors to a combination that makes better sense.

• Zoom in and out with click and drag capabilities• Simple Zoom in and out to image center• Pan• Full Extent zoom key

Experiment with each until you are comfortable

Zoom Keys might have been placed on the divider between the data layers and display window or can be accessed by using the right mouse button when in the View window, each may be slightly different we will use the right click ones first.

After you have zoomed in and out a bit the following two buttons are also available• Go back an extent (one step back)• Go forward one extent

• Experiment with these

Sometimes the Tools instead of being between the two windows they will just be “floating” around in the View window

Highlight the layer that you want to work with

Right click on the layer then scroll down and click on Properties

From the Layer Properties window that opens click on the Symbology tab then click on Symbol button

This then opens Symbol Selector which has too many choices, but we will only change the color.

Change the Hydrology to blue and also set the width to 2, hit OK to close the Symbol Selector

Looks nice! But now let’s work on the Fish Habitat layer. Start by highlighting FISHHAB and again go the th symbol selector

A faster way to get to the Symbol Selector is to click on the symbol immediately below a file name like FISHHAB

6. We have been working in the “Data View” now move into the “Layout View”

This is the Layout View this is where the final output (map) is built

From the above menu list we can add details to our map

Title in, change its size by adjusting the Font size of the text

Building the Legend

Legend inserted

Putting in Meta dataUnder Insert tab select Text a box will appear towards the center of your map, at this point start typing

Double click in this box to open a text window to type correct data and set font size and style

Moving Back into the Data View

Data View

Using the mouse buttons we are going to adjust our cities display, click on Properties

Highlight CITIES and open Properties

Right now we have a Single symbol for all cities we will change this

Click on Categories then Unique value

In the Value Field pick window scroll through the attributes to JURISDICT

Then turn off the (all other values) and click Add All Values

Click OK

Looks Good each city has a separate and Unique Color

Now let’s return to the Properties and see how to make things transparent

Again make sure that you have Unique Value & JURISDICT, unselect (all other values), Click on APPLY to make sure all is as it should be then choose the Display Tab

Again make sure that you have Unique Value & JURISDICT, and unselect (all other values), Click on APPLY to make sure all is as it should be then choose the Display Tab

Under the Display tab find the Transparent window.

Currently it is 0% or no transparency. We will change this to 50%

Make the change then click OK

RESULT

Now move CITIES to the top of the TOC so it draws first and notice how we can “see through” the cities boundaries – however this still needs some more work

Some results on the final Layout Map

Now lets add some Labels or Names.

Under the Lables tab Click on “label features in this layer”

The jurisdictions labels should appear…
