Spatial Referencing Improvements

Raster Referencing Classes

The new spatialref.GeoRasterReference and spatialref.MapRasterReference classes relate georeferenced images or data to geographic or planar coordinates. Most Mapping Toolbox functions that work with referencing vectors and matrices now work with referencing objects, as well. Unlike the older referencing matrix and vector representations, a referencing object is self-documenting, providing a rich set of properties to describe both the intrinsic and extrinsic geometry.

These functions now work with GeoRasterReference objects:

areamat	contour3m	contourfm	contourm
filterm	findm	geoshow	geotiffinfo
geotiffread	gradientm	grid2image	imbedm
latlon2pix	limitm	los2	ltln2val
mapprofile	maptrims	meshgrat	meshlsrm
meshm	neworig	pix2latlon	resizem
setltln	setpostn	usamap	vec2mtx
viewshed	worldfileread	worldfilewrite	worldmap

These functions now work with MapRasterReference objects:

geotiffinfo	geotiffread	map2pix	mapbbox
mapoutline	mapshow	mapview	pix2map
pixcenters	worldfileread	worldfilewrite

Use the new georasterref and maprasterref functions to construct GeoRasterReference and MapRasterReference objects.

Compatibility Considerations.  Use the new referencing classes instead of referencing matrices and referencing vectors. To convert referencing matrices or referencing vectors to the GeoRasterReference class, use the conversion functions refvecToGeoRasterReference and refmatToGeoRasterReference as shown:

 R = refvecToGeoRasterReference(refvec, rasterSize) 
 R = refmatToGeoRasterReference(refmat, rasterSize) 

To convert a referencing matrix to the MapRasterReference class, use the conversion function refmatToMapRasterReference as shown:

 R = refmatToMapRasterReference(refmat, rasterSize)

New geotiffwrite Function to Write GeoTIFF Files

The geotiffwrite function exports georeferenced images or data. Now, in addition to reading georeferenced images with geotiffread, you can also write them, with geotiffwrite.

WMS Database Modified

The WMS Database changes on a release-to-release basis, as some new servers are added and some unavailable servers are removed. A total of 666 servers (26.8% of the number of servers listed in R2010b) and 234,156 layers have been removed from the database. A total of 190 new servers, with 16,395 layers, have been added. The new database contains a total of 2,023 servers and 83,087 layers. Since the number of layers stored in the database is significantly reduced from earlier versions, the access time is quicker.

If you want to find one of the new servers, use wmsfind to search for the URL:

wmsfind(URL, 'SearchField', 'serverurl')

The following updates have been made to the WMS Database since the last release:

• 57 new WMS servers from NOAA's Environmental Research Division Data Access Program (ERDDAP):

  http://coastwatch.pfeg.noaa.gov/erddap/wms 

  These servers provide oceanographic data. To find out more about them, visit the ERDDAP web site.

• Two new WMS servers from the U.S. Geological Survey Coastal and Marine Program ncWMS program:

  http://coast-enviro.er.usgs.gov/ncWMS/wms)

• A new Mars Space Flight Facility MapServer:

  http://ms.mars.asu.edu/TES_TI_Putzig?

• Two new servers from the Bureau of Land Management in partnership with the U.S. Forest Service:

  http://www.geocommunicator.gov

• A new Metacarta WMS server providing images from VMP0 tiles:

  http://vmap0.tiles.osgeo.org/wms/vmap0

• A new server from the NASA Goddard Space Flight Institute providing data for the Tropical Rainfall Measuring Mission (TRMM):

  http://gdata2.sci.gsfc.nasa.gov/daac-bin/wms_trmm?

• This version of the database is significantly reduced from earlier versions primarily due to the reduction of servers (servelets) hosted by the NRL GIDB Portal server:

  http://columbo.nrlssc.navy.mil

  In R2010b, 425 servers with 228,227 layers were listed in the database. At the time of qualification, the portal server is hosting data from only 51 servers, with a total of 10,715 layers.

• The JPL Global Imagery Service server:

  http://onearth.jpl.nasa.gov/wms.cgi?

  is no longer providing full WMS services for any of the datasets. Any server (e.g., http://webapps.datafed.net/OnEarth_JPL.ogc?) that cascades data from this server is also affected by the change. The server is still included in the database. Examples in the help and reference pages that referred to this server have been updated to use a different server.

  A small subset of the data can be accessed using a non-standard TiledWMS request. The available tiled patterns can be found at:

  http://pat.jpl.nasa.gov/wms.cgi?request=GetTileService

  The WMS parameters must be in the exact order. If you wish to obtain a tile, you can use the prefix:

   'http://onearth.jpl.nasa.gov/wms.cgi?/SERVICE=WMS&'

  in front of the request (found in the CDATA section of the GetTileService request). For example:

  url = ['http://onearth.jpl.nasa.gov/wms.cgi?/SERVICE=WMS&' ... 
     'request=GetMap&layers=global_mosaic&srs=EPSG:4326&'  ... 
     'format=image/jpeg&styles=visual&width=512&height=512&' ... 
     'bbox=-180,58,-148,90']; 
  [A, R] = wmsread(url); 
  

Enhancements to geotiffinfo, geotiffread, and worldfileread

The geotiffinfo, geotiffread, and worldfileread functions now have additional syntax options. Also, the geotiffinfo function now returns information about GeoTIFF tags.

Improved Performance for gtopo30

Enhanced performance for reading GTOPO30 tiles using the gtopo30 function.

Improved Performance for gshhs

Enhanced performance for reading GSHHS data sets using the gshhs function. The gshhs function has been qualified on GSHHS releases 1.1 through 2.1 (version 8). Also, it can now read even newer versions, if they adhere to the same header format as releases 2.0 and 2.1.

The improved gshhs can now read the files below:

wdb_borders_x.b
wdb_rivers_x.b

where x is one of the letters c, l, i, h, and f, corresponding to increasing resolution.

Second Input Argument of roundn No Longer Optional

The second input argument to roundn, a real, integer-valued exponent n, is no longer optional.

Compatibility Considerations

If you omitted n in previous releases, a warning was issued and a default value of −2 was used. Now, if you omit n, you will receive an error. Change any code that calls roundn with one input argument like this: roundn(x) to this: roundn(x,-2).

Comet Menu Item Removed from maptool

The Comet menu item is no longer available in maptool. You can still call cometm directly from the command line.
