Due to an untimely departure from my previous employer I have gone into business for myself (and the job market stinks). A man has to Eat, and so does it wife and children...

I am now an independent GIS consultant focused on Telecommunications and Agriculture, my software focus is, but not limited to, Autodesk Infrastructure Design Solutions (AutoCAD Map 3D, MapGuide Enterprise, MapGuide Studio, Raster Design, and Topobase), MapGuide Open Source, and SQL Server. I also do database design, GIS system architecture and GPS fileld mapping.

I can be reached at www.gisXtreme.com and check out my history on LinkedIn!

Got my GISP!

YEEE HAW!

Just recieved my GISCI Certification Letter that states I am a GIS Professional! Here is the proof: http://www.gisxtreme.com/GISP_JM.jpg.

If you want more info go here http://www.gisci.org/

You have until Dec. 31, 2008 to be certified under the gradfathering clause on work experience alone. After that it is much heavier on Education and Contributions to the Profession.

Jeremiah, GISP (thats cool)

Creating True Scale Map Books with AutoCAD Map 3D 2009

The Map Book function has been a Part of Map 3D since the early days of ADE (check your way-back machine for that one). In the last several releases the functionality has become very robust and a whole lot easier to use due to the Sheet Set Manager and a Wizard. That being said, there is one piece of the Map Books that can cause you to go nuts (and many folks it seems just give up)… setting a % Overlap value and still getting a scaled map book. The key to solving this dilemma is in the Map Book template (.dwt). The following is a discussion of and tutorial on how to properly set up a map book template to produce a properly scaled Map Book set (and stop ramming your head against your desk).

First let’s discuss the % Overlap setting

% Overlap actually scales your viewport by the value and does NOT compensate for the Scale you set the viewport to be. THIS IS THE KEY #1
That being said, your scale affects the Viewport in your Map Book .dwt file. The Viewport has to be created to match the desired scale of the Map Book compared to the size of your Map Book Grid. To be successful in scale you must create the Grid (in model space) and use the “Custom” Tiling option. Do not use the “By Area” and “By Number” Tiling Options. THIS IS KEY #2
In order to create an appropriately sized Viewport you have to do a little math:

Yes, I also think AutoCAD is supposed to be doing the Math for us, but alas, human intervention is still alive and necessary! Let’s break down the equation…

In this example assume we have created a 1 mile by 1 mile grid and we want the scale to be 300 with a 5% overlap (24in x 24in plot):

1. Viewport Height

2. Viewport Width

The Viewport size will need to be exactly 18.48 x 18.48 inches to plot to scale.

In the next example assume we have created a 6000ft by 4000ft grid and we want the scale to be 500 with a 7% overlap (11in x 17in plot):

1. Viewport Height

2. Viewport Width

The Viewport size will need to be exactly 12.84 x 8.56 inches to plot to scale.

The Process (step by step tutorial)

Creating True Scale Map Books in Map3D

This link will walk you through the process of setting up a Map Book that will plot true to scale in Map 3D 2009. It makes use of one of the sample Map Book Templates and applies a 6000x4000ft grid, a scale of 500, and a 3% Overlap.

Please give me your feedback so I can make this better!

FDO makes life easy(er)!

Awesome! Even though I am not around as I should be my Clustr keeps getting larger. Thanks readers!

Now for some content:

FDO is cool. What is FDO? Feature Data Objects. What does it do? Makes our lives easier by allowing GIS Software to connect to non-native data sources natively with read and/or write abilities.

Where can you find it? http://fdo.osgeo.org/

Ill blog more on FDO later...
