Distributing Drawings and Maps to Users Without Software

In the world of CAD, there are people who may need to review drawings, but don't need a copy of MicroStation or AutoCAD. They just want to see the file and make a comment on it via the phone or email they don't need to mark it up or change it. This is also true to some degree for maps and imagery. The file distribution may be a one time thing and not justify an investment in software compatible with the original file format.

A typical approach to distributing files for almost everyone has been via Adobe Acrobat and the Adobe Readers. It is a rare computer user who doesn't have some version of Adobe.

Bentley has included the ability to write PDF files from MicroStation, and added the ability to move both animation and the ability to fly through buildings and over geography within the PDF file. Try several examples but be sure you have the latest version of Adobe Reader, 7.0.

While there are some limitations relative to layer control and selecting what you can see, there is a tool bar that lets you select or hide areas, and even choose from a list of pre-defined views.


Click image for larger view.

From left to right, the icons represent: Rotate, Walk (as in Walk through), Pan, Zoom, Pause Animation, Enable Extra Lighting, Background Color, Select, Show, Hide and Isolate.

There is also a list of more expansive options that you can activate with a right click on the drawing.



Just remember this is a viewing tool and it is not designed for mark-up or redlining. It fills a niche between a simple screen shot and tools like AutoVue Professional, Volo Viewer or DWF composer. At the same time, it is fairly robust as a viewing tool, as it allows you to view and traverse a 3D drawing and see animation. There is no cost to the user, and virtually no training. Note that the PDF file, when created, will support comments and attachments.

This is a different approach to providing files that can be seen in a universal viewer. As Bentley and Adobe extend the functionality, this medium will become a standard in distributing files that are no longer static, but are both dynamic and interactive.

Journal News Removes Interactive Gun Permit Map

The Lower Hudson Journal News has been under fire for publishing a map of gun permit holders in two counties in New York State  before Christma. (APB coverage 1, 2, podcast). On Friday January 18 the paper removed the interactive map. Why? Publisher Janet Hasson gave answers in a media statement and in a letter to readers.

In a statement in response to The Poynter Institute (a journalism school) she argued:

With the passage this week of the NYSAFE gun law, which allows permit holders to request their names and addresses be removed from the public record, we decided to remove the gun permit data from lohud.com at 5 pm today. While the new law does not require us to remove the data, we believe that doing so complies with its spirit. For the past four weeks, there has been vigorous debate over our publication of the permit data, which has been viewed nearly 1.2 million times by readers. One of our core missions as a newspaper is to empower our readers with as much information as possible on the critical issues they face, and guns have certainly become a top issue since the massacre in nearby Newtown, Conn. Sharing as much public information as possible provides our readers with the ability to contribute to the discussion, in any way they wish, on how to make their communities safer. We remain committed to our mission of providing the critical public service of championing free speech and open records.

In a letter to readers published on Friday she wrote:

So intense was the opposition to our publication of the names and addresses that legislation passed earlier this week in Albany included a provision allowing permit holders to request confidentiality and imposing a 120-day moratorium on the release of permit holder data.

She goes on to say that during the 27 days the map was online any one interested would have seen it and that the data would eventually be out of date. She also noted that the paper does not endorse the way the state chose to limit availability of the data.

The original map/article still includes a graphic - but it's a snapshot, a raster image, with no interactivity. Says Hasson in the letter to readers:

 And we will keep a snapshot of our map — with all its red dots — on our website to remind the community that guns are a fact of life we should never forget.

I continue to applaud the paper for requesting the data via a Freedom on Informat request, mapping it, keeping the map up despite threats and criticism and now responding to state law. I think the paper did a service to the state, to citizens and to journalism.
