|

There are two aspects to this product: the map context and the templates that |
|---|
| 22 |
provide map views of folder-ish objects. |
|---|
| 23 |
|
|---|
| 24 |
The PleiadesOpenLayers Map Context is based on the OGC's Web Map Context |
|---|
| 25 |
|
|---|
| 26 |
http://www.opengeospatial.org/standards/wmc |
|---|
| 27 |
|
|---|
| 28 |
and encodes all parameters necessary to save a map view of one or more layers |
|---|
| 29 |
from Web Map Services (WMS). Use the following values to get started with a |
|---|
| 30 |
simple physiographic map of the world: |
|---|

Spatial Reference System (string): EPSG:4326 |

| 35 |
Bounding Box (string): -180 -90 180 90 |
|---|
| 36 |
(left, bottom, right, top in decimal degrees) |

Online Resource URL (string): http://www2.demis.nl/mapserver/request.asp |
|---|
| 41 |
Styled Layer Names (string): Bathymetry,Topography,Rivers,Waterbodies |
|---|
| 42 |
|
|---|
| 43 |
Advanced WMS users may want to associate named styles with named layers. This |
|---|
| 44 |
is done with a / separator. For example: |
|---|
| 45 |
|
|---|
| 46 |
Online Resource URL: http://wms.jpl.nasa.gov/wms.cgi |
|---|
| 47 |
Styled Layer Names: global_mosaic/visual |
|---|
| 48 |
|
|---|
| 49 |
The current release provides users with no assistance in discovering servers |
|---|
| 50 |
or choosing reasonable bounding boxes, but these features are on our roadmap. |
|---|
| 51 |
|
|---|
| 52 |
The PleiadesOpenLayers ol_map_view.pt template will only work if a map context |
|---|
| 53 |
object can be found in the same container or one level higher. To make a map of |
|---|
| 54 |
site members, you should put a map context (such as the one above) in the |
|---|
| 55 |
/Members folder. |
