Natural Earth version 1.2 release notes

Posted in Miscellaneous on May 25th, 2010 by Nathaniel – 1 Comment

This update introduces supplementary hydrography features in North America and Europe that quadruple (4x) the number of lakes and rivers there. Many thanks to Tom P. for generalizing the vectors and Preston M. for adding tapering to North America (absent in Europe). In some cases the basic 10m rivers and lakes were modified to fit the new information and that’s been refreshed, as well. The North America data comes from the CEC North America Environmental Atlas. The Europe data extract is kindly provided into the public domain by the European Commission, Joint Research Centre (JRC), thanks Alfred J! Check out their original, higher resolution Europe data.

On the cultural front, North America gets roads and rails. General 10m detail roads and railroads come from the CEC North America Environmental Atlas. The supplementary roads are donated by XNR Productions and are at 1m scale, thanks Laura M. and Rob!

If you have data or time to contribute, especially to flesh out the new transportation and hydro themes, please contact me at nathaniel@naturalearthdata.com.

Note: We are not committing to building out supplementary level of detail in the rest of the world (we’re not THAT crazy!), but will incorporate such data if you contribute it. As always, we edit these data files but you should too before you publish maps using them. Feed us back corrections.

Natural Earth Version 1.1 release notes

The download manager will be updated the next couple weeks. In the meantime, please check out the ZIP, linked below, to get the 61 changed GIS shapefiles (SHP). Release notes follow.

NOTE: Version 1.1.1 corrects the name of the 50m cultural “50m_admin_0_countries” file by adding the missing “r” (XQHSANQW71), updated March 15, 2010. Thanks Ben!

Thanks to over 50 contributors for making version 1.1 happen!

Visitors: 123,000 page views since we launched in early December, 2009. Over 30,000 visits (20,000 unique) from 157 ISO countries, or 4.25 pages per visit. 65 percent are new visits. Visitors spend an average of 3 minutes 51 seconds on the site with a bounce rate less than 50 percent. Source: Google Analytics.

Downloads: 34,000. Three out of 4 downloads is ala cart, except for 10m cultural which is 1 out of every 2. Three out of every 4 downloads is for the 10m, with the rest split between 50m and the 110m.  Just less than 1 out of every 2 downloads is for the raster. Source: Download Manager.

CHANGE LOG THIS RELEASE:

Overall

  • ADDED – National Parks for the United States of America.
  • ADDED – Landscan urban polygons (masks for population extraction out of original LandScan data). Keep using the existing urban areas theme, this one is for research modeling only.
  • REMOVED – admin 0 marine boundary lines. The indicator lines are still there.

More than 50% changes

  • 10m, 50m, 110m Cities has new towns being added, 30m selection created, various corrections, now include geonames.org IDs, bounding boxes from the landscan data, and historical populations for 500 mega cities. As this triples the file size, a new “simple” version is also available with the updates, but not the full attributes.
  • 50m and 110m Admin 0 and admin-1 get better country names and thematic codes, including slight reranking of some units and link out to the Correlates of War database (cShapes).
  • 50m and 110m Admin 0 and admin-1 in 10m are rebuilt to fix coastline offset and overlaps and gaps between countries and state/province lines.
  • 10m, 50m, 110m Geographic label points for peaks and summits. Now spun off into separate feature class.
  • 110m country boundaries, missing countries, added missing mid-range islands. Includes Caspian sea and admin-0 scale ranks.
  • All files names now use “_” underscore instead of “-” in filename for better compatibility with ArcMap.
  • Handful of file name changes for consistency.

Less than 5% changes

  • 10m Rivers and lakes. A couple names, fixed the scaleRanks to show as integers rather than strings.
  • 10m, 50m Updated the geographic areas marine names (Indonesia straight).
  • 10m, 50m Updated the geographic areas polys names (Seward Penn, Alaska).
  • 10m coastline updates for Venice. Same for land and ocean.
  • 10m bathymetry updates for several island mounts.
  • 10m Antarctic ice shelves, now includes ice shelf names.
  • 10m glaciated areas: names cleaned up, feature class column filled in.
  • 10m, 50m, 110m WGS84 bounding box has more point to aid in reprojecting as a linearized curve.
  • Fixed TWF extent on the raster imagery to improve import into popular open source GIS packages.
  • 50m ocean can now project into web Mercator.
  • 110m all cultural and most physical themes now inside the +/- 180, +/- 90bounding box.

TODO, spring 2010:

  • Better thematic codes and names on admin-1 (about 50%, can someone help on the other 50%?)
  • 10m Admin 0 and admin-1 get better country names and thematic codes, including slight reranking of some units and link out to the Correlates of War database (cShapes).
  • 10m Admin 0 and admin-1 in 10m are rebuilt to fix coastline offset and overlaps and gaps between countries and state/province lines.
  • 10m Coastline and land edits in 10m: Add in Greenland islands for towns. Remove several duplicate Pacific islands.
  • 10m Admin-1 with clipped poly and lines for larger lakes. ZZ7DR1ZXAU
  • Tribal areas in the US (US Census).
  • US National Forests (CEC North American Atlas).
  • More rivers in US, Mexico, and Canada; in Europe. Selection done, tapering in progress (CEC North American Atlas; European Commission, Joint Research Centre, Institute for Environmental Sustainability). Will include minor updates to existing rank 0 to 8 rivers in terms of headwaters.
  • More towns in US, Mexico, and Canada. Selection done, location research remains on ~200 (CEC North American Atlas)
  • Roads – in US, Mexico, and Canada.
  • ArcMap MXD / Layer file

TODO NEXT, fall 2010:

  • Adding georeferenced manual shaded relief plates for select areas (US National Park Service).
  • Possibly more from the gRoads project. Data source identified. (CEC North America Atlas, gRoads CIESEN)
  • Urban areas – gain names, more towns get latLng bounding box, remove bad polygons, move some. Data source identified. (University of Madison, Wisconsin)
  • Wetlands – polygons. Data source identified. (University of Madison, Wisconsin)
  • Incorporate US physiographic regions from Matt Fox. Other refinements to the polys. Data source identified. (USGS)
  • Add in alt names for more populated places using GeoNames ids.
  • World protected areas (terrestrial, marine)

Other

  • Are we missing a theme or have one to contribute? Please comment on this post!

Planning for our first data update

Posted in Miscellaneous on December 7th, 2009 by Nathaniel – Comments Off

We’ve had a good first 3 business days and it’s rewarding to see folks writing in with corrections and addendums. This is, after all, a group volunteer effort and it’ll only get better with your input so please keep using the Corrections system and talking back in the Forums.

We’re hoping to have the first rounds of edits made before Christmas and then another update in early Spring 2010. Edits are primarily focused so far in the populated places (towns), admin-0 (countries), and physical features (point labels). The Spring update will include an overhaul of our admin-1 features with better coding for thematic mapping.

Do you have data to contribute or have time to review the existing data for errors? Great! Possible data for future updates include transportation (roads and railroads), time zones, and terrestrial hypsography. Please reference our guidelines about creating new data. If you have ideas for Natural Earth or want to show how you’re using the data in the map gallery, please drop us a line.

So far we’ve had about 7,000 visitors, over 30,000 pageviews, and about 9,000 downloads (both a la cart and combo meal) from 95 ISO countries around the world. Our average time on site of 4 minutes. Please keep it coming!
