ArcMap 9.3 Geospatial PDF output

Just learnt via the MapAction network that ArcGIS 9.3 will produce PDFs ... and when viewed in Adobe Reader 9, "tools for coordinate readout and find XY will be available". Further ... "If that same PDF is opened in any of the pay-for Acrobat products, an extended geospatial toolset is provided, including coordinate readout, find XY, geodesic measurement, and georeferenced markup". [source: ESRI]. More good details here and here.

Seems like GIS'ers - i.e. ArcGIS 9.3 users - have an improved output option more readily available now. The previous look at GeoPDF by TerraGo was not totally encouraging.

Open Source Rolls On

So, now the NY Stock Exchange runs on Open Source software. Whilst there are quite a few good Free and Open Source GIS packages that run on the Windows Operating System, is it time for the major vendors like ESRI, Intergraph, AutoDesk and Leica-ERDAS to port versions of their popular packages for the Linux Operating System?

FOSS4G2008

The annual Open Source Geospatial Software conference, Free and Open Source Geospatial 2008 (FOSS4G2008), will be held in Cape Town, South Africa from September 29 - Oct 3 2008. The theme is Open Source Geospatial: An Option for Developing Nations. The Conference Chair writes, via a widely released email:

FOSS4G is renowned for its hands-on Workshops and Labs. 2008 is no exception. The Workshop/labs track has been going well in terms of submissions. We have (as of 9th May 2008) 26 interesting and relevant submissions to choose from, ranging across a wide spectrum of GIS topics. Desktop GIS (with spatial analysis and geovisualization to the fore) is a common theme and there is a strong representation from the broad Internet GIS field (web map servers, rich internet applications/web clients, OGC web services). Themes also making an appearance are geoportals, metadata, spatial ETL and the use of spatial databases. There is also some focus on programming/scripting. The emphasis is heavily on showing what is possible with FOSS4G through practical "how-to's", getting software/services up and running quickly and trying them out. Many of the workshops emphasise the excellent Java-based tools and frameworks.

GIS Snapshot

Here's an effort to develop a simple sense of the "state of play" of GIS in the countries of Latin America and the Caribbean - the GIS Snapshot 2008. It's a brief survey anyone can take online.

It's simple and short - 16 questions including your name (optional) - and respondents don't have to be "experts" to answer it. So don't worry about being super accurate; tell me about GIS in your country as best you can. The responses for each country will be combined for the best overall picture.

The survey will be available from today to the end of July 2008. A summary of the results will be emailed back to all respondents and made available in August at the URISA 4th Caribbean GIS Conference in the Cayman Islands.

GeoPDF

Paper maps are probably the most common form of GIS output. However digital products are obviously important too. Exporting maps from one's GIS as JPEGs is one easy way to provide users with digital copies - these can be posted to websites and/or emailed to your audience who can easily view them on their computers, insert them into reports, etc. . Here's an example set of free maps of Tobago.

GeoPDFs seem to provide a more sophisticated option for the GIS professional to consider. The GeoPDF format is proprietary and it needs a piece of software (Map2PDF from TerraGo Technologies) to produce. GeoPDFs are normal PDF documents, but with interactive maps - map layers can be switched on/off, users can zoom in/out, measure distances, view coordinates and attributes and change projections. They allow a fuller presentation of your GIS dataset to your audience. Acrobat Reader is needed to view the PDF, and in order to view the interactive elements in a GeoPDF, one must first install a free Acrobat Reader plugin (GeoPDF Toolbar). The plugin is 19MB. One needs to provide contact information to get it, which seems fair.

Jean-Nicolas Poussart of the CEP, who first mentioned this product to me, offers a user opinion of Map2PDF:
I tested the free trial to create GeoPDFs and it worked fine. I am not aware of a similar free product to make GeoPDFs, but it wouldn't surprise me if we would see this soon. As Acrobat is so popular, you can imagine how interesting it becomes to use this format (PDF) to distribute interactive maps.

Jean-Nicolas also points out that each GeoPDF is only one (interactive) map. I suppose to make a mapbook, or to include one's GeoPDF in a report that also includes text and pictures, one could collate the GeoPDF(s) with a PDF(s) of the text pages - with Acrobat.

Though it's free to try, Map2PDF has a cost - but neither the company's website nor its sales representative for the LAC region is immediately forthcoming about the amount. When a company doesn't state the cost of a predefined product, a person could feel like the customers are being kept at arms length, especially when the sales department doesn't reply to enquiries. (It's understandable if the cost of a service varies, as this may depend on what the individual customer wants and/or the circumstances). In addition, a GeoPDF on the manufacturer's website - their map of sales districts - seems to have an odd error. If you can download and examine it - with the abovementioned GeoPDF Toolbar installed - you'll notice that the Equator is apparently further south than it should be. It's a small scale map, but last we knew the Equator is just north of the mouth of the Amazon, and in this GeoPDF, when queried, the Equator seems nearer to the Tropic of Capricorn. See the screenshot at left. Again, the sales representative has not responded to a request for advice on this.

So, though I haven't tried it yet myself, and I very much like the concept of distributing GIS outputs as interactive PDF maps, I'm not overly impressed by the company's approach to the outside world. For now I might just stick to my trusty Export ... JPEG.

GSDI 10

GSDI 10 was held last week at the University of the West Indies, St. Augustine, Trinidad. 'Open' - as in the Open Geospatial Consortium (OGC), open access to data and Open Source GIS - seemed to arise as technological, administrative and social aspects of building a spatial data infrastructure were elaborated on and discussed by presenters in technical and plenary sessions. More thorough information can be had from the GSDI website (abstracts, and often slides and papers).

Mark your calendars for GSDI 11. It will be held in Rotterdam on 15-19 June 2009.

We will track you ... maybe

As mentioned in the SDI-LAC mailing list, the Jamaica Observer reports that Jamaica wants to track criminal offenders, but will not provide its digital maps to the private contractor they've hired to build the tracking system. "Absolutely not" is what the Ministry of National Security has said to the request for maps.

There may be more to the story than meets the eye, as the total price tag is some US$750,000, the contract was awarded by a previous government administration and the contractor is a Jamaican company, but headquartered in California; with a website registered less than two months ago (Nov 5, 2007) and obviously put up in a hurry (if the developer/owner reads this, the first link on the home page is broken and your pages don't have Titles - not a professional job at all). The company doesn't seem to have any particular expertise in GIS, just classic accounting/financial/networking, and no visible previous customers of their tracking system.

Whilst I'm encouraged by the effort to make wider use of GIS technology in Jamaica, this issue also raises the ghost of data-sharing past/ present ... and so far the future, of the Caribbean.
