A. A. Ortega CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS

A. A. Ortega  Loading, Arranging and Exploring Layer Attributes  Add Data toolbar  Layer = map + attribute  Sorting Layers  Open Attribute table  Change Layer Properties CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS

A. A. Ortega  Zoom & Pan  Tool toolbar  Zoom, Pan and Change Map Scale CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS Zoom & Pan

A. A. Ortega  Selection Features: Selecting, Identifying and Finding Features  Select Feature Tool  Zoom to Selected Features  Statistics  Clear Selected Features  Identify Feature Tool CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS

A. A. Ortega  Finding Features  Find Toolbar CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Loading A Map CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  With ArcMap Open, click the Add Data toolbar  Search for the shapefiles (.shp) in the folders you created earlier and click Add

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Querying CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  With the layer, dtl_cnty checked, go to: Selection >Select By Attributes  Query the attributes (see illustration)

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Selecting & Creating Layers Out of Selection CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  Selected features (counties of Washington State) are highlighted  Create a new layer out of the selected features (see illustration)

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Creating Shapefiles CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  Create a new shapefile out of the layer ( see illustration ) & make sure to create your desired.shp filename in your folder ( for easy access )  Add the new shapefile using Add Data toolbar

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Creating A Choropleth Map CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  Choropleth maps are thematic maps in which areal units are shaded in proportion to measurement of variable (e.g. population density)  Right Click Layer of interest and Select Properties

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Creating A Choropleth Map CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  With Layer Properties opened, go to Symbology and then select: Quantities > Field (POP05_SQMI) > OK  A choropleth map showing population density (2005) per county within Washington State is shown

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Adding Fields and Calculating new variables CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  Examine Table Attributes of your created shapefile  Let us say we are interested to see the spatial distribution of proportion of blacks per county in Washington State  We can create a new attribute(variable) (say, variable name, pblack) for this by using the formula: pblack=black/pop2000

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Adding Fields and Calculating new variables CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  We first add a new field  Open attribute table  Right Click and Select ‘Add Field’

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Adding Fields and Calculating new variables CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  With the Add Field window open, fill-out variable specifics (name = pblack, type = double)  Right click the new variable, pblack, and click Field Calculator  With the Field Calculator window open, calculate the values (see illustration)

A. A. Ortega EXERCISE ALERT!!! 1. Make a choropleth map using the new variable, pblack. 2. Try exploring other map types, e.g. population dot maps

A. A. Ortega Easy Mapping Techniques Using ArcGIS |Map Layout CSSCR Back-to-School Seminar, Fall 2009 Introduction to ArcGIS  With our desired map made, we can proceed to create our map layout  Go to View > Layout View  In the Layout View, we can add the classic elements of maps, e.g. Title, Legend, Scale, Direction  We can save the map and convert it into image file by going to File > Export Map >
