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

The Joy of (con)Text

It's a common geo-rant (thanks AGI'09) that metadata cause alternatively boredom or angst among geo-geeks - why? because we know our data, our professional audience does too, but our wider audience does not. In other words, if we don't write metadata, no-one else will understand the context later on. I found a clear example, when I mapped Captain Cook's ships logs a while ago, and posted on ArcGIS Online beta:

Standards & Metadata, Part VIII

My previous post on this topic stated how careful documentation and appropriate metadata high-grades any information that is shared online by giving origin, context and other information. It helps build bridges and I quipped a well-known tear down this wall that also closed my second last post on free data and apps.

"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

Web 2.0 in action

The recent announcement of data.gov.uk under none other than Tim Berners-Lee is a great step towards freeing UK data to the public - I won't reiterate the arguments going back and forth between for-free (tax-paid) and for-fee (cost recovery) - and such availability has raised eyebrows even in the land of the free - namely, how useful is it to the end-user ranging from guv contractor, thru spatial business to end-users, perhaps in decreasing order of patience &/or savvy?

Unlocking Open Data from a legacy site

 In the process of looking at land cover per previous post, I found Natural England's Natural Capital Atlas - their story map encouraged me to enter EsriUK's latest competition - their Esri dataset is accompanied by ample documentation under data.gov. To save us reverting to ArcMap, let's use the provided layer files and a file geodatabase in three simple steps to map our own region on ArcGIS Pro.

"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.

Historic Fenlands Mashup

[See updates at bottom, and predecessors Medieval Fenlands GIS and Post-medieval Fenlands GIS]

Here is a mashup on giscloud.com of the geographic history of land cover and surface geology of East Anglia since Domesday based on:

Standards & Metadata - Part VI

A fable by Paolo Coelho inspired this post, a follow-on to Part V. Here is an excerpt from his e-book Stories for Parents, Children and Grandchildren - Volume 1.

Releasing data really works, Part V

It took five days (after hours) to stand up, learn, tweak and display my East Anglia Fenlands project on Mapcentia's web service. It started with a GISuser group post on LinkedIn on Monday, I used my Amazon Web Service free EC2 trial and GeoCloud2 under beta, and by Friday I had it working and styled. No small thanks to Martin Hogh's original work and help, the result is a simple yet modern and pleasing web map.

Rebranding conferences

Last week I presented at the PPDM London User Group Meeting, and the week prior at Finding Petroleum's (FP) January Conference.

"Who you gonna call?"

"Geo busters!" (apologies Ghost Busters).

Geodata access and availability is the real story behind the flurry of news around UK government freeing up some data, vs. Google collecting it and returning it for free, and many others. And this happens against a backdrop of various SDI (spatial data infrastrucutre) intiatives. I joined a UK government data developers mailing list, to educate myself on the ins-and-outs of data provision at the coal face, so to speak. And RDFa emerges as the way to resolve this - the more metadata one provides within any given dataset, the easier it is to classify and maintain internally, and to discover and distribute externally.

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.

When is a map not a map, Part II

I just posted on LinkedIn Pulse Opinions are free, but Facts are sacred, taking off from Simon Rogers ex of Guardian Data now at Google Data by way of Twitter. This was spurred by the EU Referendum, and setting aside debates raging around it, this is my contribution in my field of petroleum geology in general and mapping / GIS in particular. UN Comtrade has a fabulous collection of statistics, which are so easy to search & discover, that I simply copy&pasted screenshots into this video.

A day in the life of a petro-data manager - intro

[Update: Talend made the early version complex, so simpler one was posted later]

Have you ever been given plain text geodata and wondered how to database and map it? And has this happened to you lately with tens of thousands of lines of data? Well help is at hand! Here is an ETL  workflow (extract, transform, load) useful to any data manager in or out of petroleum using free tools:

Standards & Metadata - Part V

A quick follow-on to my series of same name posted here - I had a long email trail with a potential partner about serving up petrodata on the web, and here are a few lessons learned:

"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...

Gathering clouds over the horizon...

... intermittent sunshine and showers predicted tomorrow. No this is not a meteo prediction, but a metaphor for opportunities and confusion that cloud computing creates. I see it as a pressure-release valve, where the constant demand to deliver more for less is pushing both sectors, for-profit and not-for-profit.

Trending oilelefant.com, part VI

Last week I posted to relevant Linkedin Groups, a two-page extract on Slideshare of my article in the June Digital Energy Journal - the full source of Better Metadata for GIS can be found in my previous blogpost. I also updated slide 10 of my presentation on same.

Fun with puzzle maps, part II

 Having moved from Cambridge to my family home in SW FR, I found the historic map puzzle i described here on a previous visit.
