Development of Spatial Grids and...

The Association for Geographic Information Geocom2017 gathered at the Geographical Society in London late last October. Its Lightning Talks showcased new ideas and businesses. I was invited there to challenge attendees "to think about the development of spatial grids and the structure of spatial data models". The presentation itself and thank-you letter were followed by a short report in GIS Professional scanned here:

A tale of two cities: web maps new and old

Last I posted on vector online GIS, and that appears to be gaining traction. Mapbox offers through TileMill and OpenStreetMaps editing. These are new an emerging technologies that are exciting, and it contrasts with Esri who offers a slew of tools on the desktop and in arcgis.com. WMS is for example still immature on giscloud.com (though it is OGC compliant now), as are the symbology and labels. They do not offer model builder like Esri or Qgis (thru Sextante). But they do offer a service to process GIS functions online and allow to load data direct from web source, avoiding costly down- & up-loads. Here I compare how I used a 180K vector dataset from NOAA NGDC described previously.

Mapping Tropical Storm / Hurricane Isaac

A map slide show last year tracked dust and wind storms in Kuwait. I simply refocused it on the Gulf of Mexico to track the tropical storm Isaac, predicted to gain hurricane strength by land fall in Louisiana. It shows NOAA's cloud cover, wind direction and alert areas detailed here. [Please be patient as this map may take a while to load.]

New look and banner maps

You will have noticed that the banner picture is now a dynamic map... The monsoon season has passed and the hurricane season is starting: So let's augment the previous image of dust cover with NOAA's wind speed map too, shall we? You can zoon in&out or pan across the banner too! And you may have to "wait a sec" for the display to refresh. But I simply used the "embed" feature of ArcGIS Explorer maps, available from other packages too, and reformatted the entire banner to accommodate that.

Simple Feature or Full Feature Specification for OGC?

The issue of how to write-to and read-from geographic databases has been around for quite some time. Esri shapefiles were a runaway success partly because of their open specification. As we moved onto spatial databases, the Open Geospatial Consortium (OGC) offered the simple feature specification (SFS) that all the players could read to or write from. This came in especially handy for consuming web mapping services (those and many other specifications have grown since). But it gets trickier when it comes to reading from and writing to spatial databases generically. By that I mean not from the native application but from others', like with shape files.

Even more beautiful maps in current affairs

I'm baaack! Here is the web mapping service directly in ArcGIS Explorer (AGX). This was posted two weeks ago as a layer package on arcgis.com. I wondered then why AGX would not accept OGC WMS services? While I was away ESRI Support responded with two caveats:

More beautiful maps in current affairs

As I'm off for two weeks you get next week's posting today! Following last week's blogpost on Esri's beautiful ocean base map, I painted over it (to use their simile) Goddard Earth Sciences' stunning near-real-time global sensor data for:

"...with a little help from my friends", Part II

James Fee cracks me up every time. First he does not dance on ArcObjects' grave but praises it, secondly he exults Google Earth Builder until he, well, hits nothing, and best of all he sees off Esri's webADF to welcome its REST API. Currently in the business of hosting data on the web, his head is not in the clouds but bolted on tight by business concerns, mostly clients' who gives them a certain sharpness as they're always right, right?

"Better metadata for GIS"

Just posted my two-page extract from the June issue of Digital Energy Journal:
We are going to see much more improved "metadata" system for geo-graphical data - which will help integrate it much more closely with bigger information management systems, writes Andrew Zolnai, sales and marketing director, Interactive Net Mapping Ltd.

"The proof of the pudding is in the making"

The FOSS4G conference early this month in Barcelona raised a host of issues as usual. One picked up by James Fee and Jo Cook's blogs among others, is the role of SpatialLite in particular and exchange file formats in general? My main takeway is Jim's point, that while file exchange formats are important, efforts should be focused on internet exchange formats. We all agree that it's usage eventually that will dictate future formats, rather than vendors or standards bodies...

Standards & Metadata - Part VII

Facebook/twitter diary excerpt from an information manager:
Vast majority of information is not held on computers but in people's heads
If Information is Communication, then what is Metadata?
Monday E&P IM mantra: METADATA. METADATA. METADATA
Data, data everywhere. Hidden. [...] High value. Low awareness
Would like to take a broom to the data management techniques used

A tale of two approaches

Continuing on my "tale of two" series - conferences, cities and systems - here are current affairs promised in my previous blog. Two events displayed contrasting approaches in finding novel ways to solve old problems.

"East is east and west is west...", or is it?

Geo-meta-data news flashes:
quickly access web resources regardless of resource location via ESRI's geoportal extension
free metadata tools for the EU INPSIRE website using ESRI Irelands Be-Inspired site
quickly add data anywhere in the world, crowdsourcing debut on Google Map Maker
geocode data into the recently increased Google palette in the US at least announced

Geocommunity2009

I followed UK's premier GIS meeting hosted this week by AGI in Stratford-upon-Avon UK, on its excellent website and twitter (#geocom and other attendees). You can read there that the debate over FOSS vs. COTS is morphing into GIS vs. neo-geography. But I found the following to be very a-propos for petroleum: Yahoo!Geo Technologies' Gary Gale explains in his blog the importance of a global geographic ontology - that is identifying not only by location, but also by metadata and by topology.

What's in a name? Part II

Tim O’Reilly started the Web 2.0 movement via eponymous show a few years ago. Gov 2.0 was his iteration of same in Washington DC last week. In the All Points Blog podcast on same, APB Executive Editor Adena Schutzberg said:
...not only are they [gov. GIS sites] really, really useful, people don't think of them as GIS, they're apps: they happen to have maps in them, you get your answers to your questions...
