... visual analysis of geographic-demographic-economic patterns
Neighborhood demographic-economic patterns might be most effectively understood using GIS tools supplemented with
tabular/spreadsheet data. Geographic Information System (GIS) applications provide an appealing
and flexible way of visually examining thematic patterns ... such as patterns of median household income as one
measure of economic prosperity. By combining different layers, such as counties, cities and census tracts,
we are able to better understand patterns in the context of multiple types of geography.
This section is focused on use of GIS and related geographic-demographic-economic data to examine
You can use resources described here to flexibly examine neighborhood patterns for your areas of interest.
The GIS resources reviewed in this section are provided as a part of the ProximityOne

Visual Analysis of Neighborhood Patterns
The graphic presented below (click for larger view) shows a thematic pattern map of Connecticut census tracts by median household income.
This graphic shows the "start-up" view of the GIS project described in this section.
We will review how, in just a few steps, how you can develop maps like this one for interactive use;
perform geographic drill-down and navigation;
label tracts and other geography;
change attributes of patterns and/or variables used in thematic maps;
add other layers; and examine the data in tabular form.
Steps to Develop the Above Map (requires Windows computer with Internet connection)
1. Install the ProximityOne CV XE GIS
... run the CV XE GIS installer
... take all defaults during installation
2. Download the Connecticut Neighborhoods GIS Project zip file.
... requires ProximityOne User Group ID
(join now, no fee)
3. Expand the zip file to the folder c:\dmi.
4. Initial start-up.
... after completing the above steps and with CV XE running (use desktop icon)
... use File>Open>Dialog to open the project file named c:\dmi\ct1.gis
... the map view shown above should appear.
About the GIS Project
The GIS project includes several shapefiles, represented as layers, and OpenStreetMaps (OSM) as an optional base layer.
Use of the OSM requires an Internet connection. The OSM layer is optional. It can be deleted from the project,
However, the automatic roads and topology view is then not available.
Other than the OSM layer, there are no Internet dependencies; CV XE and this project operate without Internet.
The layers include U.S. by states, state by county, state by city/place, state by census tract.
See User Guide for information on opening and closing project.
When the GIS project is opened, the GIS project file is read; this operation is what establishes the start-up view.
No changes to the project are saved if CV XE is closed without saving the active GIS project.
If the active project is saved, the settings active at that time will be reflected when that project is subsequently opened.
It is recommended that a new name is used when a GIS project is saved.
You can add other layers, representing different shapefiles (for example schools as point locations or roads as lines), to the GIS project and save the new project.
When getting started, saving the project with the same project filename is not recommended. Simply close CV XE.
CV XE Selected Operations
See User Guide for additional information.
Develop a vision for what you want to show or analyze. A simple example would be to zoom to view of a particular county or city, highlight those boundaries,
possibly label with an item of interest (e.g. educational attainment)
and save a graphic of the new view; add the graphic to a web page or document where it might be discussed with related text. Selected CV XE operations are reviewed below.
1. Map View Navigation
2. Map View Composition -- selecting layers & setting layer attributes
click layer checkbox on in legend panel to make the layer visible.
change layer attributes -- use Layer editor to set layer attributes -- label tracts with tract code (yellow background).
slide layer up or down: click on a layer in legend panel, hold down mouse button & drag up or down.
3. View Profile for a Geographic Object -- use select/identify tool
4. View Layer Data as Table/Spreadsheet
The scroll section below shows attributes/fields available for each census tract/neighborhood.
Most items are derived from four datasets:
General Demographics (D items),
Social Characteristics (S items),
Economic Characteristics, (E items) and
Housing Characteristics (H items).
A few items (HDMA) have been derived from the HMDA
"Census 2013" dataset and integrated into the shapefile used in the project.
Several hundred additional items can be made available.
Item HMDAS1 is the Tract Income Level and determines the census tract HMDA LMI designation.
The values that this field can take on are shown as codes 0 .. 4.
Using this classification there are 5,588 tracts having a HMDAS1 value of 1 or low income.
Use vertical scroll bar at right to scroll and view all fields.
