The Data Source Report
script we posted on ESRI's
ArcScripts page solves an outstanding problem in ArcView: how to
identify the underlying data source (file or database connection) behind
every ArcView document and theme. |

We have added a new article
on bias in environmental investigation of soils. It explains and
illustrates how standard investigation and statistical procedures tend
to underestimate contamination, sometimes with enormous error. |

The popular Rotate Graphics
extension now works in all versions of ArcView 3.x, not just 3.2.
We have also expanded its capabilities: it rotates layout objects, has a
more efficient interface, and allows you to type in rotation
angles. Find out more through our software catalog. |

Our new References page,
accessible from the home page, lists books on GIS-related subjects we
have found most useful for learning or probing more deeply into the
subject. Wherever possible, there is a link from each book to
pages with further information (typically, but not always, at Amazon.com).
Our interview with Rich Turner, program manager for ArcView
development at ESRI, is appearing in two parts on the Directions
Magazine pages beginning with Part
I.
We have re-posted an article written last fall at GIS Instruction.
It summarizes answers (from 44 respondents) to our questions about
experiences with GIS courses. You can find it and more at our Articles
pages (follow the "GIS" link for more GIS articles, for
example).

The Move Docs
ArcView extension has proven so useful in managing our projects that we
have made it available on our Free Software pages.
Our article
on changing projections and datums, published last week in
Directions Magazine, has been very popular.

We have updated the Avenue
Encryption page to reference interesting materials recently
appearing elsewhere on the web.
An enhanced version of the Reproject Grids extension for

The Simple Random Sample
extension for ArcView 3.x is the newest addition to our Free
Software pages. It enhances the capabilities of the Sample
extension released last week.
The Cell IO extension for
Spatial Analyst 1.x creates a development environment in which modelers
can interface their code directly with Avenue and in which Avenue
scripts can directly change grid data values cell by cell.

The Sample extension for
ArcView 3.2 is now for sale at our Catalog
page. Anyone who has to design a spatial sampling program will
find that this inexpensive software saves time and increases the quality
of the program and its documentation. |

Read our reports
of the ESRI 2000 Users Conference: 10,000 attendees, 900 maps,
and plenty of interest in the technology underpinning the next releases
of the ArcInfo and ArcView software. |

Today we added a PowerPoint-derived
presentation ("Fitting Data," about 30 slides) requested
by a U.S. EPA workgroup concerned about assessing the risks of drinking
water disinfection byproducts. This presentation describes a
rigorous approach to analyzing data distributions as mixtures of simpler
("normal") distributions. It is already being applied to
improve human health risk assessments. |

The article on the Star
of David puzzle now features a supplement
describing how GIS was used to solve the puzzle. Techniques
discussed include finding all subsets of a set of features, determining
how many sides a polygon has, computing the elements of a permutation
group from a set of generators, and applying group elements to spatial
features. |

We have posted
several hundred pages on GIS complete with technical explanations,
how-to for ArcView and Spatial Analyst, and a highly selective and
powerful collection of links and print references. For the
beginner and advanced student both. |
