TurboCAD - Professional 2D and 3D Design Software
For less demanding users, a less expensive Turbo CAD Deluxe 2D / 3D version is available. Its 3D tools are TC Surface tools and have a limited amount of Architectural and mechanical tools.
Salient Features of Turbo CAD
1) Advanced Drawing tools include over 40 line, arc, curve, and spline tools plus over 50 modification tools. They aren’t organized exactly like Auto CAD, but they are still easy to find.2) What if analysis is provided to streamline your design process. Being able to plan ahead and see if your ideas would work out without spending a lot of time designing them.
3) Select, copy, and editing tools allow you to edit more than one component at a time and can save you time by copying similar objects and editing them to create a new object.
4) Parametric design allows you to create objects and components that you can reuse throughout your project. For those of you who are experts there is also a scripting function to design your parts.
5) The Light works rendering engine has been updated to allow illumination to be added anywhere in your design. This is a nice wow feature for when you’re doing “the sell” presentation.
6) You can connect to any ODBC database and define bill of materials, field reports, and part lists.
7) With the Arch and Platinum edition you can add sheetrock, wiring, etc. Also a nice wow feature, but also a good way to keep building costs in mind.
8 ) Doors and windows parametrically designed can be dragged and dropped into place and yes they’re self healing.
9) Stairs, railings, and slabs have all been improved and there are tons of options.
Visit IMSI/Design for a wide selection of award-winning precision design, graphics and utilities software at great prices!
Turbo CAD software is the way to go since they are offering more functionality and features.

Antique Maps
Are maps realistic representations of the actual world? No--never! Field measurements are subject to errors of accuracy and precision.A map can display only a few selected features, which are portrayed usually in highly symbolic styles according to some kind of classification scheme. In these ways, all maps are estimations, generalizations, and interpretations of true geographic conditions.As far as historians and geographers can determine, every culture in every part of the world uses and makes maps. This deep lineage reflects the descriptive usefulness of a map—a map is one of the best proofs that a “picture is worth a thousand words.”
Man has mapped the heavens from the first moment he turned his gaze upward towards the celestial sphere. There, in the unfathomable vastness of space, he found both gods and devils, truth and mystery. Upon the starry sky, and its uncounted denizens -stars, comets, moons and planets- man imprinted his greatest hopes hates and fears. The skies he peopled with his memories and his wildest imaginings. Now, as modern science has broken the barrier of the firmament and taken us even unto the moon, we reach our aspirations ever higher and farther, into the unknown realms that mapmakers populated with dreams…
Greece and Rome, and home of the nomadic invaders that destroyed them. Here, the socio-cultural background developed that would eventually birth modern science, and send its navigators to the four corners of the Earth in search of new lands, treasures and peoples. During the period when many of our maps were designed, European powers stood astride the world like colossuses, and it is through these eyes that the cartographers gazed…Antique Map Gallery

Useful links to Geostatistics
Statistical techniques and procedures are applied in all fields of academic research; wherever data are collected and summarized or wherever any numerical information is analyzed or research is conducted, statistics are needed for sound analysis and interpretation of results.
Geographers use statistics in numerous ways:
- To describe and summarize spatial data.
- To make generalizations concerning complex spatial patterns.
- To estimate the probability of outcomes for an event at a given location.
- To use samples of geographic data to infer characteristics for a larger set of geographic data (population).
- To determine if the magnitude or frequency of some phenomenon differs from one location to another.
- To learn whether an actual spatial pattern matches some expected pattern.
These Links provides useful Literatute and fundamentals of Geostatistics
- Kriging link, contains explanations of variance in geostats
- Arizona university geostats page
- A resource on the internet about geostatistics and spatial statistics
