More sources
Shelob keeps finding and adding public spatial sources: national agencies, state and city portals, utilities, transport operators and research bodies.
COVERAGE
Global, and growing
every day.
Shelob collects spatial data from governments, public agencies, GIS servers, transit feeds and open-data portals on every continent. New sources arrive all the time, and every time a source is revisited, the new version is added and the old one is kept.
OBSERVATIONSHundreds of millions, and counting

REACHEvery continent
01 / ALWAYS GROWING
A catalogue that gets bigger and deeper on its own.
More history
Sources are revisited over time. Each new version is stored alongside the last, so every place builds up a record of how it has changed.
Nothing thrown away
Two sources describing the same place stay two records. Nothing is merged or overwritten, so you can see where sources agree and where they differ.
02 / WHAT KIND OF DATA
Whatever governments and agencies publish about places.
From building footprints to flood zones, bus stops to zoning plans. What exists for a given place depends on what its publishers release.

03 / WHERE
Every continent. Deepest where publishers share the most.
Coverage is broad everywhere and richest where open-data programmes are strongest. It changes daily, so the live picture always comes from the product, not from this page.

04 / THE LIVE ANSWER
Ask what Shelob holds about your place.
Give Shelob an address, a site, a region or a map area. It tells you what it holds there right now: which sources, what kinds of data, how far back the history goes, and the licence on each record.
05 / CHANGE OVER TIME
Every observation adds to the story of a place.
Shelob keeps successive observation windows rather than replacing yesterday’s data with today’s snapshot. As the catalogue grows, each place builds up a record of what appeared, disappeared, moved or changed.

How has this place changed since 2018?
ILLUSTRATIVE ANSWER
Development and freight activity rose faster than drainage capacity. The site’s flood-exposure trajectory shifted upward.
Every observation retains its date, publisher, source and licence record.
