Spatial data export: Web Map Services

WaterWare supports a very basic WMS capability for the export of model results and selected model inputs ina georeferenced, graphical formats with links at various location (start screen main menu, selected model scenario screens) through out the system.

OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.

Geographical parameters (example)
are defined in the mapset page of the embedded GIS:

UTM zone 36N datum WGS 84 Bounding box:
E-W: 418000 - 658000 N-S: 3797000 - 3977000
PROJCS["UTM Zone 36, Northern Hemisphere", GEOGCS["wgs84", DATUM["unknown", SPHEROID["wgs84",6378137,298.257223563]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433]], PROJECTION["Transverse_Mercator"], PARAMETER["latitude_of_origin",0], PARAMETER["central_meridian",33], PARAMETER["scale_factor",0.9996], PARAMETER["false_easting",500000], PARAMETER["false_northing",0], UNIT["Meter",1]]

Configuration Options

DATE/TIME STEP: GET/POST-parameter is DIM_TIMESTEP=0..23

PARAMETER: This is selectable, e.g via the Layer (=map) name:

LAYERS=MM5_Forecast_precipitation
LAYERS=MM5_Forecast_temperature
LAYERS=MM5_Forecast_soilmoisture
implementation does only support a single layer per request (no combinations!)

DOMAIN: defined in the application defaults, Alternative domains could be supported by another paramter like DIM_DOMAIN=Turkey | DOMAIN_NAME_1 | DOMAIN_NAME_2

COLOR SETTING: TRANSPARENT=1 returns a transparent image if possible by the image format (png/gif)

IMAGE SIZE: WIDTH=width-in-pixel
