Land Ownership Layer Chopped
« on: May 24, 2011, 09:01:45 AM »
Unfortunately it seems that the BLM server where TopoFusion gets the "land ownership" layer has been reduced to only showing BLM boundaries.  See this notice:

http://www.blm.gov/nils/GeoComm/home_whatsnew.html

As of yesterday this is the new string that will work:

/wmsconnector/com.esri.wms.Esrimap/BLM_MAP_SURFACE_MGT_AGY?VERSION=1.1.1&SERVICE=WMS&REQUEST=GetMap&SRS=EPSG:4326&LAYERS=BLM+Lands,BLM+National+Monuments,BLM+Wilderness+Areas,BLM+National+Conservation+Areas&TRANSPARENT=FALSE&FORMAT=image/jpeg

As TF is currently set up you will get an error message, or just downloading tiles, when trying to use the layer.  To replace it with a new string go to Windows->WMS Custom Servers and select the Land Ownership layer.  Replace the "Request" string with the one above, then hit "Save Changes."

The forest, national park and other boundaries were removed, so it's only BLM.  I have been doing some looking to try to find a replacement or alternate, but have not been successful yet.  Will post anything here if I find it.  If you know of any WMS, google tile or other web map service that has similar data, please let us know!

Thanks and sorry about the inconvenience.

I could swear this was working just a few days ago, but I guess it was pulling up tiles off my harddrive.

I would write them as owner of a small business asking them for more information about this change in policy. The overall explanation in their notice says concern for data quality. But that's a red herring because this is a prominent link on every page of their site (data disclaimer).

http://www.geocommunicator.gov/GeoComm/GC_disclaimer.htm

They also state "Data that is not managed by the BLM was also removed from the map viewers" without giving reason.

I would emphasize that the concerns of a few (BLM claims parties, private land owners, etc) should not outweigh the benefits to the whole (all public land users, mostly people just looking for where they can and cannot go). If all agencies took their position it would not be possible to create a single map layer showing who owns what. And the idea that data in a digital database updated as changes take place is less accurate than printed maps that were updated perhaps once a decade is nonsense.

This is just my speculation, but some special interest is upset at how this public information is being used and wants its availibility and ease of access limited. Sort of like, the info is available, but you have to go to each county courthouse to look at it. In my opinion there's no excuse for our government to limit and actually spend money reducing access to public information, to become less transparent. It does not look like this change was planned or well thought through because they still label the layer as Surface Management Agency on their interactive web viewer. In fact, this agency is run in the DOI BLM branch for the purpose of showing the ownership of all federal lands, not just BLM.

http://www.blm.gov/nils/GeoComm/Metadata/sma/fedland_metadata.htm

I'll write them myself, but I think a small business owner depending on public information has a better chance of getting results. Anyone else upset by this reduction in service should write as well.

In looking for more info on the Surface Management Agency I came across this GPS file

http://www.gpsfiledepot.com/maps/view/403/

Scott, I don't know if it would be useful for TF, but if it could be turned into user overlay map(s) that would be a work around (though we'd be stuck in 2009).

Hi Scott,

It seems like this Google Earth overlay (attached) is pulling down the old land status files with all the fed agencies. Maybe it contains some info you can use to restore the tiles to TF. Or maybe it's just pulling them down from cached servers.

Thanks Steve, for the ideas and especially the last kml layer.  I will have a look at it.

Re: Land Ownership Layer Back!

That worked, Steve, though I had to push out a new version to load tiles from an IP address.  Beta available now.  Details here:

Thanks again, that was a good find.  I am not sure how long this alternate server address will stay active, but it looks good for now!

Looks like the server used in the KML that sanewcomb provided above isn't up any more.  TF can't get land ownership tiles currently.  It's been down for almost a week now, I believe, leading me to think it may have gone away.

Steve, do you remember where you got that .kml file?

Thanks.
