This part of the first Desktop Mapping series will cover Social Explorer and ArcGIS as tools to process and generate digital maps.
Social Explorer is an online GIS tool that allows you to interrogate data from the U.S. Census from the very first census to the most recent. While this portion of the workshop will assume some interest in using Social Explorer, like all other platforms, there are benefits and drawbacks for selecting this particular application.
Is Social Explorer right for me?
Do use Social Explorer if you…
- Have access to the internet
- Plan to use only U.S. census data
- Focus on the “story” of a map rather than a fully customized map
- Would like to use graphs from other data sources
- Want to share online maps
Do NOT use Social Explorer if you…
- Intend to use geographic data not a part of the U.S. census database
- Want to show data beyond:
- Census Tract
- Census Block Group
- Want to customize your own data symbolization
- Want your maps put into GoogleEarth, ArcGIS, or other desktop-based GIS solutions
Percentage below U.S. Poverty Line mapping: Data Layers
Making Visually Appealing Maps: Symbology
Exporting data out of Social Explorer: Using Reports
Fancy use of Social Explorer: Comparing, swiping, and stories
The first step is to understand that we are covering the basics of desktop GIS analysis using ESRI’s ArcGIS software suite. This is by no means an all encompassing “this is GIS” demo, but rather a view on how GIS is used to build maps from ESRI’s perspective, limited by the functionalities of the software provided.
Generally speaking, the ESRI ArcGIS suite consists of 3 parts:
- 3D GIS (ArcGlobe/ArcScene)
For the workshop, we will use only ArcCatalog and the ArcMap to demo the top 10 most used functions of GIS. Strap yourselves in and pay attention because there’s bound to be some confusion when we are visiting the wondrous land of ESRI.
A note about OpenSource Alternatives
QGIS is as an alternative to ArcGIS that is free and openly available to the public on all computing platforms. Despite the accessibility of QGIS, there is a steeper learning curve for those learning GIS for the first time. However, those seeking a free low-cost alternative to ArcGIS can apply the concepts learned in this workshop with that program.
