Among the OGC services, I guess using a WFS GetFeature with a query of
type "point intersection" against a layer that has precise shorelines, and
returning
only the hits as opposed to the records, would be better.

You could load data from Natural Earth, or if that is not precise enough,
use
the global high resolution shoreline dataset.

By the name of the layer I assume you're using GeoServer.
A request that would get you the result you want might be (mind, not
tested, and using some GeoServer
specific extensions for easier filtering):

http://host/geoserver/wfs?service=WFS&version=1.1.0&request=GetFeature&resultType=hits&CQL_FILTER=INTERSECTS(the_geom,
POINT(lat, lon))

Mind, since the above is using WFS 1.1 the coordinates will have to be
entered in lat/lon order, whilst the_geom is the name of the geometry
attribute for shapefiles in GeoServer, if you are loading into a database
check what is the actual geometry column name there)

Cheers
Andrea

Re: [OSGeo-Discuss] OpenLayers WMS OSM is LonLat in water?

[Fawcett, David (MPCA)]

I don't know what scale that you want to work at, or if you need inland water 
data also, but you might want to check out the Natural Earth data set.  The 
license is very liberal (PD).

Here is a link to the 1:10M scale oceans data:

Hi,
could someone let me know how I could find out if a chosen LonLat is in water?  
I looked at the GetFeatureInfo example, but it only applies to Tasmania map.  I 
have not been able to  find a worldwide map to use GetFeatureInfo assuming this 
is the right way to go.
Thank you

[OSGeo-Discuss] OpenLayers WMS OSM is LonLat in water?

[izzybitsie]

Hi,
could someone let me know how I could find out if a chosen LonLat is in
water?  I looked at the GetFeatureInfo example, but it only applies to
Tasmania map.  I have not been able to  find a worldwide map to use
GetFeatureInfo assuming this is the right way to go.
Thank you

[OSGeo-Discuss] json request to web map ?

[karsten]

Hi All,
 
I have been working with web mapping for quite a while but always with data
pulled from files or databases on the server. Now I was wondering about
suggestions how to go about mapping data I can request from a JSON feed such
as the following
http://sourceforge.net/projects/gvsigce/files/stats/json?start_date=2010-01-
01
 &end_date=2012-10-10 (which are the download
statistic for gvSIG CE) 
 
Especially if anyone has done something like that without pulling into a
data base table before rendering...
How would you do that and which tools would you use ?
I would preferably use OpenLayers and MapServer...
Cheers
Karsten

[OSGeo-Discuss] Open Source Geospatial Research and Education Lab established at North Carolina State University

[Suchith Anand]

It is my pleasure to announce the establishment of first Open Source Geospatial 
Research and Education (OSGeoREL) Laboratory in the United States at the Center 
for Earth Observation, North Carolina State University, Raleigh.  The 
laboratory is one of the founding members of a worldwide network developed 
under the auspices of the ICA-OSGeo Memorandum of Understanding (MoU).

In 2011, the International Cartographic Association (ICA) signed a Memorandum 
of Understanding (MoU) with the Open Source Geospatial Foundation (OSGeo) with 
a view to develop global collaboration opportunities for academia, industry and 
government organisations in the field of open source GIS software and data. The 
MoU aims to provide expertise and support for the establishment of Open Source 
Geospatial Laboratories and Research Centres across the world to support the 
development of open source geospatial software technologies, training and 
expertise.

OSGeoREL at NCSU is led by Dr. Helena Mitasova and Dr. Laura Tateosian.  The 
laboratory has an established program in graduate education in geospatial 
information science and technology using FOSS4G and extensive research in 
geospatial analysis, modelling and visualization with focus on natural 
resources.

Dr. Helena Mitasova is an Associate Professor at the Department of Marine, 
Earth and Atmospheric Sciences, OSGeo charter member since 2006, member of the 
OSGeo education and conference committees and Sol Katz award recipient  
http://www.osgeo.org/solkatz She has been actively involved in the GRASS 
GIS development since 1991 and together with Markus Neteler she has co-authored 
the first book about GRASS GIS.

Dr. Laura Tateosian is Research Assistant Professor at the Center for Earth 
Observation Her research interest focus is on visualization, human visual 
perception, computer graphics, geospatial sciences, non-photorealistic 
rendering, and human-computer interaction.


More details of the lab at http://gis.ncsu.edu/osgeorel/


For those of you attending the Open Source Geospatial Research and Education 
Symposium (OGRS 2012) http://www.ogrs2012.org/  later this month it will be 
good opportunity to also hear  Helena's Keynote presentation  on "Building open 
source geospatial education at research universities" to get more ideas on 
future research activities.

Our aim is to  establish 20 new research labs in the next 3 years. These new 
research labs are strategic to  help us accelerate research developments in 
this research area for the future. If your university wishes to establish Open 
Source Geospatial Lab, please contact me and i will be pleased to discuss 
details.

We look forward for your active participation for building up Open Source, Open 
Standards, Open Data research globally and helping share the benefits of 
geospatial technologies to all.

Best wishes,

Suchith
