Bournemouth University\u2019s Geographic Information Systems (GIS) Development Officer Mark Dover recalls his Google Under-the-Earth: Seeing Beneath Stonehenge journey.<\/strong><\/p>\n

With the launch of the KMZ, knowing that the data is \u201cfree\u201d, being used and hopefully enjoyed in Google Earth, has made me reminisce about my time on the Google Under-the-Earth: Seeing Beneath Stonehenge.<\/p>\n

In the last few weeks before launch I\u2019ve worked feverishly editing KML code, checking Sketchup model imports and\u00a0re-positioning\u00a0Gigapan\u00a0panoramas\u00a0so they hugged the ground again.<\/p>\n

What stays with me is how easy it was to bring in anything we had created using the Google suite of products. Sometimes there were\u00a0glitches, but there was always a forum or blog post from someone who\u2019d encountered the bug, solved it, or had a workaround we could adapt and use. We rarely had to turn to our Google\u00a0Liaison.<\/p>\n

Most of our problems came from exporting GIS layers into Google Earth, and only then because of the difficulties of changing\u00a0Map Projections.<\/a>\u00a0The normal tools for this work well, but we needed our British Grid data to map exactly into the Google globe \u201creal location\u201d, rather than within a few meters. We had resigned ourselves to a complicated series of imports, map proofing and educated adjustments.<\/p>\n

Luckily we had our\u00a0Eureka\u00a0moment. \u00a0My colleague Harry Manley was showing me Google Earth\u2019s historical Aerial imagery.\u00a0I\u00a0knew one Aerial photography flight had just happened to catch some of our trenches being excavated in 2005; perhaps it was in Google Earth\u2019s historical Aerial Imagery? Harry moved the slider to 2005 and there were the trenches.<\/p>\n

We could then adjust our transformation so that our trench outlines fitted exactly, used the same formula for other applicable data and produced similar\u00a0work-flows\u00a0for the rest of our material. If we were doing it now, the \u201con the fly\u201d re-projection in open-source GISprograms like\u00a0Qgis<\/a>\u00a0is actually pretty amazing, as is its KMl export.<\/p>\n

Google<\/a>\u00a0has\u00a0brought GI and GIS map data to everyone (in fact they\u2019ve made it ubiquitous, recently celebrating\u00a01 billion downloads<\/a>\u00a0in September). Anyone\u00a0can now create, edit and share the\u00a0geography\u00a0that interests them, from our Stonehenge Landscape data to\u00a0Chinese Military Installations<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
