Is GIS Really for Dummies?
A new book has just recently been published called GIS For Dummies by Dr. Michael N. DeMers. Dr. DeMers is an associate professor in the Department of Geography at the New Mexico State University. This book helps introduce the Geospatial industry to those who may not be familiar with Geographic Information Systems. If you are not sure what GIS is, then I would suggest that you check it out! It seems to cover a little bit of everything.
For those of you have been in the GIS industry for a while, I question the actual need for this book. I understand that a lot of people think they are GIS professional, but are far from it. They would definitely benefit. I find it interesting that the authors describe its readers with this statement:
Whether you’re in charge of creating GIS applications for your business or you simply love maps, you’ll find GIS For Dummies is packed with information.
Do application developers really compare to map lovers? There is a big gap there. I do not think that one book can really cover adequately this entire spectrum. As a GIS professional, I would think that if there is a particular topic we want to learn then we will find a more specific GIS book.
Although I have yet to read this book, I would be very curious to see what this books holds. As stated on the back of the book, the following can be found within the pages:
- How to get paper maps into your computer
- How to create animated GIS output
- Different ways to measure distance
- How to organize your spatial data
- What raster and vector mean to a cartographer
- How to choose a GIS software vendor
- How GIS can help you determine appropriate land use
- Dozens of applications for GIS queries and analyses
All I can say is that you should form your own opinion. As an individual, you will find your own personal benefits that others will not. You will only get out of this book what you expect. Expect nothing, get nothing.

Geocoding – Guide to Address Locating in ArcMap
January 27, 2009 by Timothy
Filed under ArcGIS, Data Management, GIS Tips
Geocoding is a process that enables you to match database records to a real world location based upon attribute fields such as addresses, PINs, Cities, etc. Carrying out this process in ArcMap is very simple and can be completed in just a few steps.
Note: This example uses addresses, but other attributes can be used.
1. Compile Address Table – This can be done in excel, access, or other compatible file format .

2. Create Address Locator – The address locator will be based upon the data that needs to be located and the reference data.
- Open ArcCatalog
- Open desired folder for Locator to be saved in
- Right click in contents area
- Click New -> Address Locator…
3. Choose Locator Style – This will depend upon the source data and reference data. These data types need to correlate.
4. Set Address Locator Options

- Match corresponding fields – This will vary by locator style. US Streets is shown here.
- Set Matching Options – You will find which configuration works best through trial and error.
- Click Ok
Your locator has now been create and is shown in ArcCatalog via the “House” icon.
5. Add Address Table to Map – You can add Excel tables directly into ArcMap (9.2 or later) or create a .dbf table to be added in.
6. Right Click Table -> Geocode Addresses…
7. Add Locator to Map and Select it to be Used – You will need to browse to the folder (via the “Add..” button) that contains the created locator.
8. Complete Locator/Geocoding Options
- Select Corresponding Input Fields
- Choose Output Location
- Click Ok
Status is updated during geocoding process and results are shown on map.
10. You can Review or Rematch Any Address
- Right Click on geocoded point file in Table of Contents

Customize ArcMap Toolbars
One of the greatest benefits of ArcMap is the ability to customize the tool bars. There are many tools that are not visible on the standard tool bars. Some users do not even know the extra tools exist. The process requires only a few steps.
1. Click on the Tools menu at the top of the map document.
2. Select Customize….
This will open the Customize dialog. The Toolbars tab allow you to select which toolbars are visible. The Commands tab will bring up tools organized by categories. The Options tab will allow you change certain settings. I recommend browsing through the commands; you never know what you might find.
3. Once you find the tool you want, click and drag it to a location on a toolbar.
Customization of ArcGIS is a great benefit once you learn how to do it. It will allow you to add and remove tools. Customizing the interface can go as far you your imagination will take you. For additional tips on customiztion and the begining of using Visual Basic for Applications (VBA), I highly recommend the book: Getting to Know ArcObjects. I got so hooked to this book that I read and worked through it in five days. Get your copy today!
