From static to dynamic maps, my travel so far

I tell people "I know just enough java to be dangerous", and it has served my well in my prior attempts logged in my old web page. These were all Google Maps API v.2 I built about 5 years ago. This blog as well as my new map catalog showed how I built maps in QGIS then ArcGIS, and then posted them on giscloud.com and AWS via Mapcentia GeoCloud2. I recently posted maps on arcgis.com on desktop and smartphone, static results of 'traveling salesman' geoprocessing on the desktop or online.

Handy maps

A 'handy' is what Germans call a mobile or cell phone. I uploaded free ArcGIS for Android on my  smartphone, which now has a decent screen to read maps on - love my Navigon Europe on it, and Google Maps too - but here is a quick&easy application of arcgis.com for the rest of us. 

... now HOW open is open?

[Update: Part II is on my Medium professional channel 2½ year later: Almost open data]

A lot of (virtual) ink has flowed around opening up data, as in this blog, GISuser crowdsourcing open data (below left) etc. etc. And everyone is getting into the act, from White House (below center) and Whitehall (UK Cabinet Office) to the number of open data hits (below right).

Releasing data really works, Part VI

Three months into posting data on my web service - Part V - I created a short list of free data for Great Britain on my Map Catalog called GB Freebie.

Global Sailings (1662 - 1856, English, Spanish, Dutch, French) revisited

[Update: climate data (wind speed & direction) have now been added in short & long posts]

I originally extracted CLIWOC (CLImatological database for the World's OCeans) ship captains' logs ships locations over a decade ago, to demonstrate the processing of 250K+ points in ArcGIS desktop using then new File Geodatabase. Five years later I posted this on my old website with instructions how to use it in  old ArcGIS Explorer and KML, and then I put a layer package on arcgis.com - both related historic details like de laPerouse's demise below, the importance of data standards and metadata, and the interst it generated elsewhere - more recently I posted a time-based variation of same, where using a time slider helps clarifiy complex data on desktop GIS.

Maps are forever (Part III)

My first post on this theme traced beautiful medieval maps from the British library in London to the Harvard Libray online, to land on a 1610 beauty.

My map catalog also works well to post new projects: added British Geological Survey web mapping services to East Anglia web map, in order to compare historic and current geology. The Snapshot format also give a variety of viewing options of the catalog.

Map catalog continued

In my ongoing suite of posting webmaps in my new and fresh Mind the Map blog, here is another take on loading global vectore megadatasets but this time on Amazon Web Services direct via Mapcentia's GeoCloud.

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.

More map catalog

Last week was the inaugural post of my catalog, highlighting maps from this blog in (very) roughly reverse chronological order. The second entry make the display options more evident, as this is meant to be a light and flexible version of this more complete blog. I am not about to end its success quite yet, and have no fear I will post items of substance as well as cross-links to the catalog until it has its own followers.
