ows.js's Introduction

#ows.js

Build Status

OGC Web Services Library for JavaScript.

This Library is based in the awesome work of Jsonix & ogc-schemas libraries.

Implemented so far

  • Basic Ows operations (ex: GetCapabilities)

  • CSW

    • GetRecords
    • GetRecordById
    • GetDomain
    • GetCapabilities (Refactored)
    • Transactions:
      • Create
      • Update
      • Delete

  • OGC Filters

    • Operators:
      • Logical Operators:
        • AND
        • OR
    • Spatial Operatos:
      • BBOX
    • Comparison
      • isLike
      • isBetween
      • isEqualTo
      • isLessThanOrEqualTo
      • isGreaterThan
      • isLessThan
      • isGreaterThanOrEqualTo
      • isNotEqualTo

Next TODOS

  • Clean Ows.js deprecated code.
  • Implement NOT operator.
  • PropertyIsNull
  • Improve Unit-Tests (Help is extremely Welcome here :D)
  • DescribeRecord

in the Future

  • WPS
  • WFS
  • SLD
  • etc...

Getting started

How to install ows.js in your project.

It is recommended to use bower, because this project depends on Jsonix and Ogc-schemas libraries.

 bower install ows.js --save

Using and configure CSW

The CSW standard strongly depends on catalogues profiles. So first you need to determine what profile you want to use and include its depencies:

####Basic CSW

Include in you project:

<script type="text/javascript" src="../bower_components/ogc-schemas/lib/OWS_1_0_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/DC_1_1.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/DCT.js"></script>
<script type="text/javascript" src="../bower_components/w3c-schemas/lib/XLink_1_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/CSW_2_0_2.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/Filter_1_1_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/GML_3_1_1.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/SMIL_2_0_Language.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/SMIL_2_0.js"></script>

Configure CSW:

var cswConfig = [
            [
                OWS_1_0_0,
                DC_1_1,
                DCT,
                XLink_1_0,
                SMIL_2_0,
                SMIL_2_0_Language,
                GML_3_1_1,
                Filter_1_1_0,
                CSW_2_0_2,
                GML_3_1_1
            ],
            {
                namespacePrefixes: {
                    'http://www.opengis.net/cat/csw/2.0.2': 'csw',
                    "http://www.opengis.net/ogc": 'ogc',
                    "http://www.opengis.net/gml": "gml",
                    "http://purl.org/dc/elements/1.1/":"dc",
                    "http://purl.org/dc/terms/":"dct"
                },
                mappingStyle : 'simplified'
            }
        ];

                mappingStyle : 'simplified'
            }
        ];

Make a request

Simple

var cswConfig = ..... ; //
var csw = new Ows4js.Csw('http://youcatalogueurl/', cswConfig);

csw.GetRecords(1,10).then(function(result){
    console.log(result);
});

With a ogc-filter

var cswConfig = ..... ; //
var csw = new Ows4js.Csw('http://youcatalogueurl/', cswConfig);
 
var filter = new Ows4js.Filter().PropertyName('dc:title').isLike('%water%');
filter = filter.and(new Ows4js.Filter().PropertyName('dc:subject').isLike('%polution%'));
filter = filter.and(new Ows4js.Filter().BBOX(-80, 150, 80, -150, 'urn:x-ogc:def:crs:EPSG:6.11:4326'));


csw.GetRecords(1,10, filter).then(function(result){
    console.log(result);
});
