MapCruzinTM Learn2MapTM Tutorial and Atlas

Introduction - Startup - Sample Project
Your Project - Add More - Free GIS - Conclusion


In this first section I have prepared a simple mapping project that will help to introduce you to digital mapping. It is based on U.S. Census Tiger 2000 files (more on this later) and ArcExplorer, a free GIS program from ESRI. The sample project covers my home county, Santa Cruz, California. We will work on this together - step-by-step. First you will download ArcExplorer, the free GIS from ESRI, and install it. Then you will download the mapping project that I have prepared. Later on you will learn how to create your own mapping project and add a variety of map layers.

One way to think about all of this is to imagine a paper map -- a base map -- that may have such features as the outline of county, perhaps some topography, major roads, etc. If you wanted a single map with more than that, some features might obscure others. The solution to this is to add map layers. Layers can be thought of as transparencies that you would place on top of your paper map allowing you to see the base map as well as the added features as you add, remove and change the order of the layers. As you work with ArcExplorer this will become clear.

Downloading ArcExplorer

Update: 11/02/2010 - ArcExplorer 2.2 is no longer supported by ESRI. If you have trouble with it in Windows Vista/7, some folks have said that they were able to make it work by switching to the XP mode. If that does not work or if you would like to try later versions of ArcExplorer or another free GIS program, check here. If you do use a different program the Arcexplorer project file will not work for you, but you can add each shapefile to your map with any of the other programs and then save as a project in their format.

The first thing to do is to download the GIS viewer, ArcExplorer. Note that ESRI is no longer supporting this version of ArcExplorer (see above).

Download ArcExplorer 2.0 to any directory that suits you (I like c:/mapcruzin_maps/downloads/). Once you have downloaded the program, go to the directory on your hard disk where you downloaded it, double-click on its icon and follow the installation steps.

Downloading the Sample Project

The next step is to download the sample project for Santa Cruz County, California. Further along in the tutorial you will find instructions for downloading the files for your county. We will get to that later. The project includes the map layers, listed below, in a single file archive (scruz.exe). Click here to download scruz.exe (1.6mb).

Map layers included in the Santa Cruz County project (check the readme.html included in scruz.exe for layer details).

  • Census Tracts 2000

  • Congressional Districts

  • Designated Places

  • Key Geographic Locations

  • Landmark Points

  • Landmark Polygons

  • Line Features - Hydrography

  • Line Features - Misc. Transport

  • Line Features - Non-visible

  • Line Features - Physical

  • Line Features - Rails

  • Line Features - Roads

  • School Districts - Elementary

  • School Districts - Secondary

  • School Districts - Unified

  • Urban Areas

  • Water Polygons

Go to the file archive, "scruz.exe," on your hard disk.

Double-click on the file name and a  dialogue box will open. 

Click on "unzip" and the file archive will automatically unzip creating 56 new files in a new directory on your hard disk named "mapcruzin_maps" (c:/mapcruzin_maps).

If you wish, you can over ride this default and unzip the maps to any directory that you prefer.
