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.

Vectors are your friend, Part II (updated)

[Update: ESRI blog post here for clear explanation and treatment of same, thanks Eileen Buckley! See also my ArcGIS Online / Amazon Web Services update at bottom...]

Following on my previous post about giscloud.com posting vector maps directly on-line in HTML5, I loaded NOAA's GSHHG - A Global Self-consistent, Hierarchical, High-resolution Geography Database in its entirety. You must be crazy, you say, to load a 425 Mb dataset on line! But here is the workflow:

RSPB2013 bird counts mapped

Releasing data really works, Continued

RSPB 2013 Big Garden Bird Watch released data by county, listing bird counts for each county in order of abundance. Why not then transpose these into one row of bird types (73) per recorded county (96, excl. N Ireland):

Maps are forever (Part II)

I wrote earlier about a 1610 map from the Harvard University Library of the Cambridge UK region, a snapshot of which I simply edited the tear and restored it by eye-balling it in Photoshop Elements. I detailed before some local history and geology too.

Mapping languages on the internet

[Update: I noted on many of my Google Fusion Table posts that, while the data are still on Google Drive for you to view, GFT no longer offers a polygon or heatmap option, only geocoding by country centroid in its new version. Not sure why, but on this, this, this and another example posted as Iframes not Scripts preserved the old GFT maps.]

Let's explore global language distribution from World Mapper, then language usage on the internet as seen from Wikipedia. This was inspired by an article in The Economist as well as data I previously collected an posted on Google Drive to explore various topics on Google Fusion Tables.

"Free Google" e-Book review

JM Internet Group published a guide to "Free SEO, Social Media, and AdWords Resources from Google for Small Business Marketing". I am offering it an honest review as a former net'preneur - I use the internet social media round-trip to help along this blog today and oilelefant.com a while back, and shared my experiences on SlideShare. I also create web maps, and without any further technical ado let's say Google were less than forthcoming in providing help with crossing an API upgrade... This echoes  author Jason McDonald's (JM) reason to write "Free Google..." in the first place! He set out to render explicit for the rest of us what is implicit to geekdom and help 'free Google' from itself.

Local maps one year on from Kuwait

Hard to believe it's over a year since I left Kuwait, and I'm back in Cambridge now working west of London - the shortest commute yet, weekly as opposed to every 10 weeks in Kuwait or every two weeks in Milan three years ago - so just out of curiosity I looked for web maps of the area again.

Google Fusion Tables for new Google Maps?

[Update: I noted on many of my Google Fusion Table posts that, while the data are still on Google Drive for you to view, GFT no longer offers a polygon or heatmap option, only geocoding by country centroid as evidenced below. Not sure why, but on this, this, this and another example posted as Iframes not Scripts preserved the old GFT maps.]

I posted on my old website a number of Google Maps in v.2 API that I have not converted to v.3. I also used Google Fusion Tables a number of times under the 'old look' - the 'new look' doesn't afford Heat Maps and polygon rendering as yet out-of-the-box - along comes a Google Fusion Tool that helps both on v.3 API and the new régime with very simple Google Fusion Table templates and new  rendering.

"The shots heard around the world"

Recent mass shootings in the US and elsewhere affect me in a particular way: My parents grew up in Nazi then Soviet occupied Pest, on the east shore of the Danube overlooked by the Buda Castle (dark green below), from which guns fired down streets perpendicular to the river (grey at right below), so residents literally ran the gauntlet across those streets, and friends of my parents lost a babe in arms from a stray bullet; my parents thus emigrated just before my birth to give me a better life, but that included six months in Algiers during a revolution where I too witnessed two fatalities early 1961.

Maps are forever...

... or they are Man's best friend. I'm a big fan of the British Library, not only because it's next to Kings Cross station I alight when coming to London often (or rarely hop onto the Eurostar at nearby St Pancras to Bruxelles or Paris) - bl.uk has an amazing array of old maps, which they just finished georeferencing through a significant effort in crowd-sourcing (the 21st. c. variant of volunteering).
